Well, good! Heat is pretty much a dead limit, and bigger coolers only give diminishing returns. So if there's a heat limit, less heat per core means more cores, and cores are computers and computers are good!

Then he showed the backside of the back-plane with a tangle of yellow wires which needed to be configured to your setup. That's when my confidence waned.

@@MOSMASTERING I'm a little surprised that Dave didn't spring for a chiller. Given the machine was twenty grand, another few kilodollars for a real chiller isn't unrealistic.
@@BinkyTheToaster Haha.. Kilodollars, I like it. Given the increase in prices in just about everything right now, I'm assuming kilodollars are how I'll be describing my weekly grocery shop... I think he mentioned something about this being as loan CPU for testing, so probably isn't allowed to screw with it too much. I'm upgrading my studio computer at the end of this year and I can't get a straight answer from anyone about what chip would serve me best, audio processing is an extremely unusual set of variables split between single core power and threads. I posted here in the hope Dave might find a way of doing benchmarks for audio type stuff..
@@MOSMASTERING that's true about the "loaner cpu." I was just thinking that the chiller would give the cores a bit more thermal overhead to run the clocks higher than what a simple closed-loop 420 would allow. I'm hoping to do a PCVR rig by EoY if only to cram it into an InWin POC (the green/yellow, it's total cyberpunk), but I want the video feed coming out the top USB/Displayport and I'm not sure how to rig a card to do that.
4:30 Dave I suggest running folding@home if you ever want to run multi gpu tests and look at the points per hour calculation and test the entire system
8:14 Dave (or anyone for that matter!) should probably have a look at Mold, it's a modern drop-in replacement for the GNU/GCC and LLVM linkers and it takes advantage of multiple cores. It's a bit dark wizardry, but it works amazingly well. Can't imagine how fast it would link huge project binaries on a 7995WX :-)
It would be something that needs to get stable and adopted by the projects first, because thats what matters. you'd need to check if the final program with that linker is as well optimized etc
Can I just say, the colour grading and quality of video seems immaculate... better than 90% of "professional" UA-cam channels.. Considering the amount of lights, RGB and various colours all around you - its all captured and reproduced fantastically. I assume you know what you're doing with video encoding types. I haven't made videos in well over 15 years, so I'm totally out of touch with anything video related.
The uncore of these CPUs uses a lot of power. AnandTech did a really good write-up on older Threadripper processors which covered the high uncore power usage. My own old and 'lowly' TR2950X uses 35-45W for the uncore and 25-135W for the cores. The wider Infinity Fabric on the same generation of Epyc processors the uncore was 66-86W while core was 10-90W. Even disabling a lot of the cores still requires a lot of uncore power use.
They couldn't just call it "non-core", could they, the bunch of autists? Between the bionic hive-mind of the chip designers, and the monkeys on Macintoshes in marketing, that term somehow escaped out into the public. Even the smartest people are getting stupider.
@@Salzui Voltage is kind of irrelevant in that instance. The uncore of the 5600X is much smaller than on a Threadripper and uses a lot less power. You can use something like HWMonitor to see the core/uncore power use under Windows.
I have to say, this is my first time viewing your channel and I loved listening to your content, excellent presentation, very professional indeed. I'm an intel XEON fanboy too, really enjoyed the content. :D
Not sure why I wasn’t subbed in the past having watched a few vids here and there when they popped up In the feed. Great enjoyable content my dood! Keep up the the great work!
For an all in one watercooling system like this, I'd expect the maximum sustained dissipation to sit somewhere between 200-350W for a desktop CPU, possibly a bit more for this setup since the heatspreader is so enormous. For 1000W you basically need a custom loop with some MoRa external radiators or a waterchiller. "For some reason or another, I could never get their RGB software working" - that's a very common occurance, it's amazing how all of these RGB software suites manage to be even worse than the next. Great video by the way, you've gotten really good at these. Compare the way you're speaking now to some of your earliest videos, quite the difference.
You're seriously underestimating how much heat a small radiator can dissipate if you don't mind the water getting a bit toasty and the fans getting a bit noisy. Remember the >300W GPUs with a single 120mm radiator AIO for cooling? I do...
@@Steamrick I had some of those, yeah (6900XTXH LC). There are other issues aside from just the total amount of heat where radiator size can help you. The quality of your waterblock matters a lot more at 500W+ than at 200W. At 1kW you should have a dedicated product and not something that is primarily designed for desktop platforms. The highest dissipation I cooled for prolonged amounts of time was with intel's skylake-x, where CPU-only I got to around 750W. To keep this from thermal throttling, I needed to run the best available block directly on the die instead of using the integrated heatspreader, since while my radiators could dissipate the heat, my block could not keep up with the additional layers between it and the core. At some point, you cannot buy a better waterblock anymore (or run into diminishing returns), but may still run into thermal throttling regardless even if you could theoretically dissipate enough heat via your radiators. Once you reach that point, reducing your coolant temperature by having more surface area to work with (or using a water chiller) helps immensely with this issue. You'll also want a good pump or course!
Threadripper's the reason that I got into custom water cooling. The only AIO that fully covered the TR was the Enermax cooler and people were complaining about them failing (the coolant turned to sludge). They've had a few revisions since then, so I don't know if they still have that issue or not.
yes they do. go heatkiller iv or similar, there are many choices but not enermax. anyway if you do have an enermax, clean it and refill it with pure distilled water +1 drop each of Mayhems Inhibitor+ / Mayhems Biocide+ (or similar). i think the problem is in the materials they used. i'll never touch enermax again
Given V-core is likely around 1.4v under load, we can guess that socket was pumping a bit over 700A into the CPU through all those little pins. I've welded with a lot less current that that.
First, love the video! The absurdity of just taking a 96 core threadripper and turning on PBO is amazing. Second, I take minor issue with "you can only do 350W of work no matter the core counter". The energy efficiency of modern processors goes up dramatically when you slow them down. If you have enough work to keep 96 cores busy, 96 cores at 350W will do it a lot faster than 16 cores at 350W. That is assuming of course you have the IO to keep the 96 cores fed, which is not a small consideration. This threadripper is amazing is that it can effectively do both, it has a ton of cores for parallel work, and still has 5+GHz when the work gets single thready. Third, minor suggestion. I am an AMD enthusiast and I'd like to suggest you explore undervolting. PBO has a setting called the Curve Optimizer and what it does is give you a voltage offset that scales with the CPU's standard voltage setting at any given speed. The brilliance here is you aren't dialing in a big change that you'd want at a higher clock speed all the time. Quick primer done, AMD chips today seem to love undervolting. I have a 5800X3D and I set a -30 curve offset, which made my CPU clock about 5% faster under a prime95 test load at the same power limit. 5% isn't massive at 8 cores, but it's basically free performance, and on 96 cores that might be an impressive jump. Keep tinkering, I love this stuff. 🙂
Also, those extra cores will reduce the amount of context switching. Each one gets it's own L1 and L2, so you will have a higher hit rate. I would expect some workloads to benefit a lot more from more cores.
Very interesting stuff, Dave! I built my own system a couple of years ago. I didn't give myself a completely unlimited budget, but I didn't cheap out. Luckily, I did my research and kept everything in spec and made sure everything fit without modification. Thus, I've never had unstable performance or stability issues. I think that's the biggest takeaway from your video.
Surprised a guy like you Dave, didn't build a custom water loop. First time watching your channel. I miss Dos 6.0...starting to play with it in middle school.
Hey Dave, just so you know, your channel is NOT that small!! Kudos to get 3 of those beasts.. Shoot I'm excited I grabbed a 5800x3d (I play games on that machine) for 289 nib.. Oh well.
As someone that do not have any RGB or window in my pc. Honestly I would recommend you to make a water cool loop. It is great fun, looking at different blocks adding all the radiates you can fint in your case and set the fan speed to below audible levels. I use soft tubing and fittings that hold on tight, ran the loop without booting the pc, got all the air out of the loop and made sure there was no leaks. Honestly it is pretty easy but very satisfying.
As someone who does have a window, and is running a H110 for almost 10 years now, the fans are very quiet, system is 3x as quiet as a laptop, with 120mm fans but that damn pump noise, cuts through everything and is louder than a 3.5" hard drive. The pump noise alone is worth avoiding liquid cooling if you can, at least in my opinion. Otherwise it would be whisper quiet, I'm talking about my i7 4770k system, ancient by modern standards but still kicking! :)
@@q1337 I have no pump noice. The only noise i have is coil whine from the GPU when passing ~300 FPS. It is not often I hear that. But still annoying. If you had the system for 10 years you have probably tried this. 1. Tray moving the pump while it is running to move air that might be stuck in the pump. Try to get the air stuck at the top of the loop, have the tubes at the lowest point of the radiator and so on. 2. Try changing the pump speed to see if this changes the sound. 3. Top off the loop with demineralized water. 4. Well after 10 years you could clean the loop. Maybe dere is something stuck in the pump. If you had an open loop you could have changed the pump.
@@Petch85 Yeah, well I have it mounted the classic way on the fan slots at the top of the motherboard, the tubes are horizontally aligned with the radiator so water flow is optimal, I set the pump 3 pin (CPU fan header) to max power, no control years ago since I read the pump was designed to be run at max speed, fans were the things that were to be adjusted as needed, besides, the pump is even louder when going slower, topping off a fully closed off AIO is a good idea after so long, but since I doubt there is buildup (since it's fully closed off, and sounds exactly the same for the last 10 years) I'm not gonna bother with it. The most amazing thing I should mention is it's still under warranty :D It came with a 10 year warranty and im around one quarter away from that time. I know tech improved and maybe I just chose the wrong AIO at the time (in regards to noise, cooling is great, max ~50c at 3.9GHz full load all cores with HT) but with the advancement of noctua air coolers I'm gonna finally completely get rid of the slight pump noise. To be completely clear, the pump is very silent, but the thing is when the rest of the system is dead silent (5x 120mm noctua fans with low noise adapters, corsair psu that is passively cooled (never reaches 50% usage))it sticks out as the only thing you can hear.
@@q1337 No I get it. If something makes noise it makes noise and that is frustrating. And You are right that a good air cooler can probably do about just as well an AIO. I am not the biggest fan of AIO's myself, but on the other hand I do understand why people like them. They seem easy. But I perfer open loops. Cause you can clean them your self, add GPU cooling, add as much radiators as you case can handle. And when you get a new pc, you can just reuse it. But they are more expensive and a little harder to install. I have had 2 water cooling pumps over the years, and non of them had made any sound. I have installed them with some soft material to avoid any vibrations traveling though the tower. And I am just running them at a fixed speed (I adjust the fan speed depending on the water temp in the loop, but I have 2x360 radiators and my delta temp is never above 6 C, so the fans are always running super slow). But to hear the water pumps you need to have the side panels off and have your head inside the tower. And at that point you can hear the moving air around you head anyway and it is hard to see the screen. 😂 My tower has a little sound dampening material But I have 8 fan + the PSU fan, thus the tower is pretty open, and I promise you, you cannot hear the pump from outside the tower. At one point I had two loops in the same pc, and even with two pumps you could not hear the pumps at all. I have worked on a friends pc that had a Corsair h80, but I don't remember hearing the pump. But that Pc had a lot of other problems, the 120 mm puss/pull fans was unnecessary loud. We ended up changing the cooler for an air cooler, because the block was installed using the wrong stand-offs and therefore did not make good contact with the CPU. So I never really focused on the pump sound. So I can't tell you if your pump sound is normal or not. But it does not sound normal to me, I would not expect to be able to here the pump on a system installed in a normal pc case from outside the case.
@@Petch85 I replaced the fans on my h110 before installing it with noctua 120mms NH12 i think, and my case is a corsair 750D with the front panel removed (idiots designed it with 0 air intake, but put 2 120mm fans behind it) since the replacement "Airflow" panel was a ripoff. I admit it would sound a tiny bit quieter if I put it on but I'm not the only one that complained about the pump. It's probably just how it's designed to work, It is after all somewhat early design of AIOs, no rgb, all black, wires seem cheap etc. But like I said, it's not that big of a deal just the fans hit a certain frequency and this thing hits another and stands out. as for custom vs this, I never wanted to have something I needed to think about maintaining, just wanted to put it in and forget it. For that part it did it wonderfully. One critical thing that pissed me off was there was no refill hole/access port, they completely sealed it which due to the use of rubber etc is not perfect and eventually it will run out of liquid, I mean I doubt many people use their AIO for nearly 10 years but still, how much could it cost them for 1 hole with a fitting so I can refill/flush it without drilling it
I was going to buy that motherboard just to enlarge my E-Penis, but I couldn't find any other justification to own one. So I settled for half a dozen Dell R610's and a server rack enclosure. I love the loud jet-like fan noise/heat emanating from them. It's absolute bliss when everything at home is powered 24/7 with solar panels and 45KW hours of lifepo4 batteries. Dave here too, but not a plumber - cheers from Texas
Thank you, Dave, for always bringing us the relevant information that we need without all the frills and bullshit some channels dabble in. It's refreshing to find what's needed in the age of clickbait. Stay fresh and keep it real, Dave.
This was very informative. Thank you for your excellent videos. I wonder if the core count will continue to increase and eventually high-core-count processors will become a commodity. I expect the technology will no longer be silicon by the time that happens, and the power requirements will be lower.
On the subject of custom watercooling - I'd always recommend steering clear of bending pipes (aka hard tubing) and go with industrial black ZMT instead. The compression fittings are foolproof and in 5 years I've had exactly 1 leak - and that was because I forgot to put a blanking plug into on of the ports on my GPU block.
So l ong as you also make sure to use the right tubing cutter, and also to lubricate the O ring seals insode the fittings as well before inserting the tube. Makes a big difference to them, especially at the larger sizes, and at the small end where those seals have very little leeway in them.
Would love to see NiceHash CPU mining on XMRig using the RandomX as a benchmark. Would be fun to see how it compares and then you could also test the 100% workload how it affects the cooling system, which you did later in the video using other ways. Good job!
Back in the early 1990s I bought a Sun 3/160 from a guy out in East Bay. I remember opening up the front of the cabinet and seeing the sticker “1.5 KW” on the power supply. Went straight to KW, no messing around with Watts. 😊
I assume you mean Asetek pump at 13:15 instead of "Asus tech". Asetek makes proprietary pump designs that are used in many different brands all-in-one liquid coolers, including Asus obviouisly. Arctic, on the other hand, makes their own pump design in-house for the Liquid Freezer II and the just released Liquid Freezer III.
Awesome video! Loved the results and the custom machine for the 1kw tests. Only thing I would’ve changed on it is upgrade the PSU to a 1500-1600w (maybe more) one, might reduce the chance of crashes with the extra headroom since the cores are pulling 1kw with the CPU’s IO die pulling probably 100-150w plus the rest of the system, then the 1200w PSU isn’t up to snuff anymore. (I’m sure it can handle a bit of a overload, but not for 15-30 mins haha)
Dave, custom water cooling is no big deal and is not very difficult, given a case big enough and designed for it. The key is measuring and planning with appropriate parts that will fit. Don't be afraid of it as the benefit will be well worth the effort.
Really sweet. As I remember when dirt was invented, it's always good to see one of my generation rocking the absolute cutting edge kit. Hope to live long enough to catch one of these chips that I could afford on the used market, maybe. I rather enjoy seeing what percentage of the latest and greatest with my outdated, used gear. I think Dell (or one of the OEMs) just announced plans to accommodate a 1000w GPU from nVidia. Maybe you'll have to revisit your 1000w CPU paired with whatever 1000w GPU seems to be in the pipeline?
I’m thinking that one of the PDP 11’s might be able to compete on the thermal side of the challenge. I enjoy watching you working projects which go as far back as the PDP and Altair and as up to date as the Threadrippers. Of all my old PDP collection the only part I use on a regular basis is my old DEC coffee cup. Thanks.
Omg I'm jealous of the custom built you did. I could configure that sucker to run well. That 512gb of ddr5 5800 is no doubt putting the board traces to the test. You could completely get stability with 5200 m/ts. Good logic for figuring out the waterblock issue.
Dave I just purchased a thermal contact plate for my Intel 13th gen cpu. It replaces the stock bracket and gives it more surface area to dissipate heat.
I’ve never listened to such a highly concentrated stream of super specific techno verbiage for so long while maintaining an absolute lock on the thread and attaining complete comprehension. Then again I was an hp engineer at the same time as Dave was at Microsoft so I suspect we’re simply bypassing the interpreter part of the human brain and going straight to the back plane.
I've run into that with memory several time, even when you buy the exact DIMMs recommended by the MB maker, they often just done run stably at specified speed under load. I once bought a replacement mother board thinking I had a thermal issue and later discovered that there was a single bad row in a brand new DIMM when the new MB had the exact same symptoms of the old one. D'Oh
@14:15 If that AMD 7995WX Threadripper uses the same tech as their 7000 series CPUs, they were engineered to push to 95C at all times. Most of the Tech Tubers I watch all ran into this (Gamers Nexus, Hardware Unboxed, etc...). The CPUs push to 95C then throttle to keep the temps around 95C. I do not personally own one. I have a 3900X build, a 5900X build, and a 5800X3d build so I do not know how true that is.
Interesting and entertaining! It would make an excellent fan or radiator heater for winter; simple heaters do nothing but heat. The expense is a bit of a stopper for me. Then there is the question of what work I would really need it to do. That is impressive.
I have a Puget System's workstation at home. They were worth every penny. More than a year after purchase they are still incredibly responsive to queries and I am confident if, god forbid, I had any hardware issues they would resolve them within the terms of their warranties with no bullshit (and that is a big reason for why I was ok with the higher price, no back and fourth). Additionally if the root cause of any failure was out of warranty they wouldn't hesitate to give me all the information I needed to order a replacement part.
That's awesome Dave! Can't afford a system like that yet but man, what a beast! Thinking maybe a 7960X non pro with more RAM than I have now (architecture / 3D rendering) would work.
Ah, waiting on compilers/cross-assemblers. Spent a 'few' hours doing that in the early '80's running a bit-slice assembler on a PDP-ll/70. Took an hour for every run. The AMD 2901 4-bit slice disk-controllers typically had a 48 to 64 bit control-store 'word' which required recompiling MANY times during the the controllers development. A Ryzen back then would have made life simpler. Eventually 'canned' uP's were used, i.e. 8X300 or 80186, which came with a pre-defined instructions set.
I talked to the friendly and very helpful people at Puget Systems, but they don't do water cooled. I was planning to put in the basement where it won't heat up the office and is closer to the distribution panel and its noise won't be a problem. Sometimes it is true that.

Then he showed the backside of the back-plane with a tangle of yellow wires which needed to be configured to your setup. That's when my confidence waned. When I saw the power plug, I knew: Even if I could buy such a system, and even I I could configure it, the electricity bill would kill me.
Tip top content once again...appreciate the effort... We all know you do this out of love - and we LOVE it!
Very well researched, written, presented, and produced! Great job, Dave :)
Dave, power on! You've created and are maintaining a garage that exists in my dreams. Thanks for sharing.
Yes, we did teach a rock to think, but not to oversimplify; first you have to flatten the rock and put lightning inside of it.
Then covered it in water
@@MOSMASTERING I'm a little surprised that Dave didn't spring for a chiller. Given the machine was twenty grand, another few kilodollars for a real chiller isn't unrealistic.
@@BinkyTheToaster
Haha.. Kilodollars, I like it.
Given the increase in prices in just about everything right now, I'm assuming kilodollars are how I'll be describing my weekly grocery shop...
I think he mentioned something about this being as loan CPU for testing, so probably isn't allowed to screw with it too much.
I'm upgrading my studio computer at the end of this year and I can't get a straight answer from anyone about what chip would serve me best, audio processing is an extremely unusual set of variables split between single core power and threads. I posted here in the hope Dave might find a way of doing benchmarks for audio type stuff..
@@MOSMASTERING that's true about the "loaner cpu." I was just thinking that the chiller would give the cores a bit more thermal overhead to run the clocks higher than what a simple closed-loop 420 would allow.
I'm hoping to do a PCVR rig by EoY if only to cram it into an InWin POC (the green/yellow, it's total cyberpunk), but I want the video feed coming out the top USB/Displayport and I'm not sure how to rig a card to do that.
Define "a rock" what is it composed of? Can it process? What are the properties? These are important things!
I'm really enjoying your videos, Dave.. excellent presentations, man...
It's been sometime since I cared about the main processor but your presentation made the instantiation of these new threadrippers into a new light!
Glad you got the samples to test and thanks for your eval. My wife is an elementary school special ed teacher and I got her your book for Christmas.
4:30 Dave I suggest running folding@home if you ever want to run multi gpu tests and look at the points per hour calculation and test the entire system
Can be tricky though as not all work units scale to more CUDA cores, though admittedly its seems a lot rarer lately to get a WU that doesn't.
8:14 Dave (or anyone for that matter!) should probably have a look at Mold, it's a modern drop-in replacement for the GNU/GCC and LLVM linkers and it takes advantage of multiple cores. It's a bit dark wizardry, but it works amazingly well. Can't imagine how fast it would link huge project binaries on a 7995WX :-)
It would be something that needs to get stable and adopted by the projects first, because thats what matters. you'd need to check if the final program with that linker is as well optimized etc
Can I just say, the colour grading and quality of video seems immaculate... better than 90% of "professional" UA-cam channels..
Considering the amount of lights, RGB and various colours all around you - its all captured and reproduced fantastically.
I assume you know what you're doing with video encoding types. I haven't made videos in well over 15 years, so I'm totally out of touch with anything video related.
That looked like a clip from "Running on empty" a classic. Nice work again mate, loved every minute of it.
can't believe I've only just found your channel. at least I have found it now. thank you Dave I'll be here for every new video now I'm subscribed.
The uncore of these CPUs uses a lot of power. AnandTech did a really good write-up on older Threadripper processors which covered the high uncore power usage. My own old and 'lowly' TR2950X uses 35-45W for the uncore and 25-135W for the cores. The wider Infinity Fabric on the same generation of Epyc processors the uncore was 66-86W while core was 10-90W. Even disabling a lot of the cores still requires a lot of uncore power use.
High "uncore" is not just a threadripper problem. my motherboard wanted to get 1.2v into uncore of a 5600x, it runs rockstable with ~0.88 or so for me
They couldn't just call it "non-core", could they, the bunch of autists? Between the bionic hive-mind of the chip designers, and the monkeys on Macintoshes in marketing, that term somehow escaped out into the public. Even the smartest people are getting stupider.
@@Salzui Voltage is kind of irrelevant in that instance. The uncore of the 5600X is much smaller than on a Threadripper and uses a lot less power. You can use something like HWMonitor to see the core/uncore power use under Windows.
I have to say, this is my first time viewing your channel and I loved listening to your content, excellent presentation, very professional indeed. I'm an intel XEON fanboy too, really enjoyed the content. :D
He’s been a Plumber for a year decades now 😂😂😂😂😂😂😂 Nice one Dave, I see what you did there.
Not sure why I wasn’t subbed in the past having watched a few vids here and there when they popped up In the feed. Great enjoyable content my dood!
Keep up the the great work!
I love this channel. You are amazing at explaining things with great detail and as a bonus, you are playing with some cool toys too!
Nice to see a channel where I can check in once in a while and see what the fastest PC in the world is like :)
For an all in one watercooling system like this, I'd expect the maximum sustained dissipation to sit somewhere between 200-350W for a desktop CPU, possibly a bit more for this setup since the heatspreader is so enormous. For 1000W you basically need a custom loop with some MoRa external radiators or a waterchiller.
"For some reason or another, I could never get their RGB software working" - that's a very common occurance, it's amazing how all of these RGB software suites manage to be even worse than the next.
Great video by the way, you've gotten really good at these. Compare the way you're speaking now to some of your earliest videos, quite the difference.
You're seriously underestimating how much heat a small radiator can dissipate if you don't mind the water getting a bit toasty and the fans getting a bit noisy. Remember the >300W GPUs with a single 120mm radiator AIO for cooling? I do...
@@Steamrick I had some of those, yeah (6900XTXH LC). There are other issues aside from just the total amount of heat where radiator size can help you.
The quality of your waterblock matters a lot more at 500W+ than at 200W. At 1kW you should have a dedicated product and not something that is primarily designed for desktop platforms. The highest dissipation I cooled for prolonged amounts of time was with intel's skylake-x, where CPU-only I got to around 750W. To keep this from thermal throttling, I needed to run the best available block directly on the die instead of using the integrated heatspreader, since while my radiators could dissipate the heat, my block could not keep up with the additional layers between it and the core. At some point, you cannot buy a better waterblock anymore (or run into diminishing returns), but may still run into thermal throttling regardless even if you could theoretically dissipate enough heat via your radiators.
Once you reach that point, reducing your coolant temperature by having more surface area to work with (or using a water chiller) helps immensely with this issue. You'll also want a good pump or course!
Threadripper's the reason that I got into custom water cooling. The only AIO that fully covered the TR was the Enermax cooler and people were complaining about them failing (the coolant turned to sludge). They've had a few revisions since then, so I don't know if they still have that issue or not.
yes they do. go heatkiller iv or similar, there are many choices but not enermax.
anyway if you do have an enermax, clean it and refill it with pure distilled water +1 drop each of Mayhems Inhibitor+ / Mayhems Biocide+ (or similar).
i think the problem is in the materials they used. i'll never touch enermax again
This is great! I've been trying to decide between buying an OEM and building a custom 7995WX system. This was exactly the data I needed.
"when its allowed to run free and eat" Love it, because it is eating amps and spitting out watts! Thanks for leaving that in!
Given V-core is likely around 1.4v under load, we can guess that socket was pumping a bit over 700A into the CPU through all those little pins. I've welded with a lot less current that that.
First, love the video! The absurdity of just taking a 96 core threadripper and turning on PBO is amazing.
Second, I take minor issue with "you can only do 350W of work no matter the core counter". The energy efficiency of modern processors goes up dramatically when you slow them down. If you have enough work to keep 96 cores busy, 96 cores at 350W will do it a lot faster than 16 cores at 350W. That is assuming of course you have the IO to keep the 96 cores fed, which is not a small consideration. This threadripper is amazing is that it can effectively do both, it has a ton of cores for parallel work, and still has 5+GHz when the work gets single thready.
Third, minor suggestion. I am an AMD enthusiast and I'd like to suggest you explore undervolting. PBO has a setting called the Curve Optimizer and what it does is give you a voltage offset that scales with the CPU's standard voltage setting at any given speed. The brilliance here is you aren't dialing in a big change that you'd want at a higher clock speed all the time. Quick primer done, AMD chips today seem to love undervolting. I have a 5800X3D and I set a -30 curve offset, which made my CPU clock about 5% faster under a prime95 test load at the same power limit. 5% isn't massive at 8 cores, but it's basically free performance, and on 96 cores that might be an impressive jump.
Keep tinkering, I love this stuff. 🙂
Thanks! That's why I was careful to note that its not linear... not every watt is equal!
Yeah, 4.5Ghz for all 96 Cores is enough for desktop usage.
Even as workstation, were sustained workloads need some wiggle room for an all nighter 😁
Also, those extra cores will reduce the amount of context switching. Each one gets it's own L1 and L2, so you will have a higher hit rate.
I would expect some workloads to benefit a lot more from more cores.
This is the first time watching your channel really enjoyed this video. Thanks.
Glad you enjoyed it!
So the Chromium browser is bigger than the Linux kernel? That surprised me.
These days browsers are operating systems by themselves.
Very interesting stuff, Dave! I built my own system a couple of years ago. I didn't give myself a completely unlimited budget, but I didn't cheap out. Luckily, I did my research and kept everything in spec and made sure everything fit without modification. Thus, I've never had unstable performance or stability issues. I think that's the biggest takeaway from your video.
Excellent video, Cheers Dave
Thank you for translating the wattage to horsepower. Finally the gap between my two greatest interests, since childhood, has been closed.
Great video on the 7995WX.
at around 8mins 50seconds that scanline shader or whatever it is, is magic to my eyes !!!! thanks
Surprised a guy like you Dave, didn't build a custom water loop. First time watching your channel. I miss Dos 6.0...starting to play with it in middle school.
thank you for this awesome video dave
Hey Dave, just so you know, your channel is NOT that small!! Kudos to get 3 of those beasts.. Shoot I'm excited I grabbed a 5800x3d (I play games on that machine) for 289 nib.. Oh well.
Great episode
GOOD GREIF! I guess that's why I watch Dave.
I love these ultra high performance PC videos!
As someone that do not have any RGB or window in my pc.
Honestly I would recommend you to make a water cool loop. It is great fun, looking at different blocks adding all the radiates you can fint in your case and set the fan speed to below audible levels. I use soft tubing and fittings that hold on tight, ran the loop without booting the pc, got all the air out of the loop and made sure there was no leaks. Honestly it is pretty easy but very satisfying.
As someone who does have a window, and is running a H110 for almost 10 years now, the fans are very quiet, system is 3x as quiet as a laptop, with 120mm fans but that damn pump noise, cuts through everything and is louder than a 3.5" hard drive. The pump noise alone is worth avoiding liquid cooling if you can, at least in my opinion. Otherwise it would be whisper quiet, I'm talking about my i7 4770k system, ancient by modern standards but still kicking! :)
@@q1337 I have no pump noice. The only noise i have is coil whine from the GPU when passing ~300 FPS. It is not often I hear that. But still annoying.
If you had the system for 10 years you have probably tried this.
1. Tray moving the pump while it is running to move air that might be stuck in the pump. Try to get the air stuck at the top of the loop, have the tubes at the lowest point of the radiator and so on.
2. Try changing the pump speed to see if this changes the sound.
3. Top off the loop with demineralized water.
4. Well after 10 years you could clean the loop. Maybe dere is something stuck in the pump.
If you had an open loop you could have changed the pump.
@@Petch85 Yeah, well I have it mounted the classic way on the fan slots at the top of the motherboard, the tubes are horizontally aligned with the radiator so water flow is optimal, I set the pump 3 pin (CPU fan header) to max power, no control years ago since I read the pump was designed to be run at max speed, fans were the things that were to be adjusted as needed, besides, the pump is even louder when going slower, topping off a fully closed off AIO is a good idea after so long, but since I doubt there is buildup (since it's fully closed off, and sounds exactly the same for the last 10 years) I'm not gonna bother with it. The most amazing thing I should mention is it's still under warranty :D It came with a 10 year warranty and im around one quarter away from that time. I know tech improved and maybe I just chose the wrong AIO at the time (in regards to noise, cooling is great, max ~50c at 3.9GHz full load all cores with HT) but with the advancement of noctua air coolers I'm gonna finally completely get rid of the slight pump noise. To be completely clear, the pump is very silent, but the thing is when the rest of the system is dead silent (5x 120mm noctua fans with low noise adapters, corsair psu that is passively cooled (never reaches 50% usage))it sticks out as the only thing you can hear.
@@q1337 No I get it. If something makes noise it makes noise and that is frustrating. And You are right that a good air cooler can probably do about just as well an AIO.
I am not the biggest fan of AIO's myself, but on the other hand I do understand why people like them. They seem easy. But I perfer open loops. Cause you can clean them your self, add GPU cooling, add as much radiators as you case can handle. And when you get a new pc, you can just reuse it. But they are more expensive and a little harder to install.
I have had 2 water cooling pumps over the years, and non of them had made any sound. I have installed them with some soft material to avoid any vibrations traveling though the tower. And I am just running them at a fixed speed (I adjust the fan speed depending on the water temp in the loop, but I have 2x360 radiators and my delta temp is never above 6 C, so the fans are always running super slow). But to hear the water pumps you need to have the side panels off and have your head inside the tower. And at that point you can hear the moving air around you head anyway and it is hard to see the screen. 😂
My tower has a little sound dampening material But I have 8 fan + the PSU fan, thus the tower is pretty open, and I promise you, you cannot hear the pump from outside the tower. At one point I had two loops in the same pc, and even with two pumps you could not hear the pumps at all.
I have worked on a friends pc that had a Corsair h80, but I don't remember hearing the pump. But that Pc had a lot of other problems, the 120 mm puss/pull fans was unnecessary loud. We ended up changing the cooler for an air cooler, because the block was installed using the wrong stand-offs and therefore did not make good contact with the CPU. So I never really focused on the pump sound. So I can't tell you if your pump sound is normal or not. But it does not sound normal to me, I would not expect to be able to here the pump on a system installed in a normal pc case from outside the case.
@@Petch85 I replaced the fans on my h110 before installing it with noctua 120mms NH12 i think, and my case is a corsair 750D with the front panel removed (idiots designed it with 0 air intake, but put 2 120mm fans behind it) since the replacement "Airflow" panel was a ripoff. I admit it would sound a tiny bit quieter if I put it on but I'm not the only one that complained about the pump. It's probably just how it's designed to work, It is after all somewhat early design of AIOs, no rgb, all black, wires seem cheap etc. But like I said, it's not that big of a deal just the fans hit a certain frequency and this thing hits another and stands out. as for custom vs this, I never wanted to have something I needed to think about maintaining, just wanted to put it in and forget it. For that part it did it wonderfully. One critical thing that pissed me off was there was no refill hole/access port, they completely sealed it which due to the use of rubber etc is not perfect and eventually it will run out of liquid, I mean I doubt many people use their AIO for nearly 10 years but still, how much could it cost them for 1 hole with a fitting so I can refill/flush it without drilling it
You Got It!
Great Video!!
Thank You!!
I was going to buy that motherboard just to enlarge my E-Penis, but I couldn't find any other justification to own one. So I settled for half a dozen Dell R610's and a server rack enclosure. I love the loud jet-like fan noise/heat emanating from them. It's absolute bliss when everything at home is powered 24/7 with solar panels and 45KW hours of lifepo4 batteries. Dave here too, but not a plumber - cheers from Texas
Right on. Thanks for sharing.
BRAVO!!! Thank you for the Engineering!
Great video Dave!!
Amazing video Dave!
Thank you, Dave, for always bringing us the relevant information that we need without all the frills and bullshit some channels dabble in. It's refreshing to find what's needed in the age of clickbait. Stay fresh and keep it real, Dave.
Thanks Dave!
This was very informative. Thank you for your excellent videos.
I wonder if the core count will continue to increase and eventually high-core-count processors will become a commodity.
I expect the technology will no longer be silicon by the time that happens, and the power requirements will be lower.
On the subject of custom watercooling - I'd always recommend steering clear of bending pipes (aka hard tubing) and go with industrial black ZMT instead. The compression fittings are foolproof and in 5 years I've had exactly 1 leak - and that was because I forgot to put a blanking plug into on of the ports on my GPU block.
So l ong as you also make sure to use the right tubing cutter, and also to lubricate the O ring seals insode the fittings as well before inserting the tube. Makes a big difference to them, especially at the larger sizes, and at the small end where those seals have very little leeway in them.
Oh wow, I got my 14900k to pull 375 continuous... after about 5 mins the mo-bo became heat soaked and we blue screened... 1000w is wild!
Would love to see NiceHash CPU mining on XMRig using the RandomX as a benchmark. Would be fun to see how it compares and then you could also test the 100% workload how it affects the cooling system, which you did later in the video using other ways. Good job!
"Run free and eat..." I love that! Now I have to look for opportunities to use it.
Putting the ripper into Threadripper!
Back in the early 1990s I bought a Sun 3/160 from a guy out in East Bay. I remember opening up the front of the cabinet and seeing the sticker “1.5 KW” on the power supply. Went straight to KW, no messing around with Watts. 😊
I assume you mean Asetek pump at 13:15 instead of "Asus tech". Asetek makes proprietary pump designs that are used in many different brands all-in-one liquid coolers, including Asus obviouisly. Arctic, on the other hand, makes their own pump design in-house for the Liquid Freezer II and the just released Liquid Freezer III.
Very cool. Yup on the Spectrum.
Awesome video! Loved the results and the custom machine for the 1kw tests. Only thing I would’ve changed on it is upgrade the PSU to a 1500-1600w (maybe more) one, might reduce the chance of crashes with the extra headroom since the cores are pulling 1kw with the CPU’s IO die pulling probably 100-150w plus the rest of the system, then the 1200w PSU isn’t up to snuff anymore. (I’m sure it can handle a bit of a overload, but not for 15-30 mins haha)
Might explain random spontaneous reboots.
Now compiling chrome in under an hour, that’s a flex.
In germany we say "Völlig sinnlos, aber geil!" ... keep up the good work😍
That blooper was hilarious. Utterly bonkers performance on your custom build.
Dave, custom water cooling is no big deal and is not very difficult, given a case big enough and designed for it. The key is measuring and planning with appropriate parts that will fit. Don't be afraid of it as the benefit will be well worth the effort.
Too much hassle
thanks for this bucketful knowledge you shared dave
Really sweet. As I remember when dirt was invented, it's always good to see one of my generation rocking the absolute cutting edge kit.
Hope to live long enough to catch one of these chips that I could afford on the used market, maybe. I rather enjoy seeing what percentage of the latest and greatest with my outdated, used gear.
I think Dell (or one of the OEMs) just announced plans to accommodate a 1000w GPU from nVidia.
Maybe you'll have to revisit your 1000w CPU paired with whatever 1000w GPU seems to be in the pipeline?
I’m thinking that one of the PDP 11’s might be able to compete on the thermal side of the challenge. I enjoy watching you working projects which go as far back as the PDP and Altair and as up to date as the Threadrippers. Of all my old PDP collection the only part I use on a regular basis is my old DEC coffee cup. Thanks.
Omg I'm jealous of the custom built you did. I could configure that sucker to run well. That 512gb of ddr5 5800 is no doubt putting the board traces to the test. You could completely get stability with 5200 m/ts. Good logic for figuring out the waterblock issue.
Dave I just purchased a thermal contact plate for my Intel 13th gen cpu. It replaces the stock bracket and gives it more surface area to dissipate heat.
at 7:07 you said gpu when you meant cpu - amazing video as always!
More outtakes please Dave- genuinely funny!
I always wondered what it would look like if I were to do this. thanks!
I’ve never listened to such a highly concentrated stream of super specific techno verbiage for so long while maintaining an absolute lock on the thread and attaining complete comprehension. Then again I was an hp engineer at the same time as Dave was at Microsoft so I suspect we’re simply bypassing the interpreter part of the human brain and going straight to the back plane.
I wonder how long it will be before these kinds of setups are consider "old school" or "vintage". Amazing how far we have come.
nVidia's latest Grace Hopper CAUs- possibly the most expensive silicon ever sold on the open market- can dissipate over 1kW of heat in operation.
Epic video.
A custom water block with compression fittings and some proper rads/fans (dual d5 pumps) could probably shave alot more off that time.
I've run into that with memory several time, even when you buy the exact DIMMs recommended by the MB maker, they often just done run stably at specified speed under load. I once bought a replacement mother board thinking I had a thermal issue and later discovered that there was a single bad row in a brand new DIMM when the new MB had the exact same symptoms of the old one. D'Oh
Just WOW the design of the CPU and supporting hardware is awesome. Major kudos score for everyone at AMD and I am an Intel devotee.
Nice - we need it to make the ‘one task per docker’ as fast as the ‘one thread per task’ was on the pentium.
Just keep in mind that the Enermax Liqtech TR4 have had a lot of issues with corrosion and precipitation inside. Not sure if that has been fixed.
The latest models have fixed the issue. It was the first two versions that were borked due to using mixed metals.
@14:15 If that AMD 7995WX Threadripper uses the same tech as their 7000 series CPUs, they were engineered to push to 95C at all times.
Most of the Tech Tubers I watch all ran into this (Gamers Nexus, Hardware Unboxed, etc...). The CPUs push to 95C then throttle to keep the temps around 95C. I do not personally own one. I have a 3900X build, a 5900X build, and a 5800X3d build so I do not know how true that is.
15:32 "Even though I've been a Plummer for many decades" Aww! What a cute pun 😊
Interesting and entertaining! It would make an excellent fan or radiator heater for winter; simple heaters do nothing but heat. The expense is a bit of a stopper for me. Then there is the question of what work I would really need it to do. That is impressive.
Excellent video as always. Did the homebrew prove to be stable in the longer term?
Love your content, Dave! OMG, 1k watts. $10k😪
I have a Puget System's workstation at home. They were worth every penny. More than a year after purchase they are still incredibly responsive to queries and I am confident if, god forbid, I had any hardware issues they would resolve them within the terms of their warranties with no bullshit (and that is a big reason for why I was ok with the higher price, no back and fourth). Additionally if the root cause of any failure was out of warranty they wouldn't hesitate to give me all the information I needed to order a replacement part.
That's awesome Dave! Can't afford a system like that yet but man, what a beast! Thinking maybe a 7960X non pro with more RAM than I have now (architecture / 3D rendering) would work.
Ah, waiting on compilers/cross-assemblers. Spent a 'few' hours doing that in the early '80's running a bit-slice assembler on a PDP-ll/70. Took an hour for every run. The AMD 2901 4-bit slice disk-controllers typically had a 48 to 64 bit control-store 'word' which required recompiling MANY times during the the controllers development. A Ryzen back then would have made life simpler. Eventually 'canned' uP's were used, i.e. 8X300 or 80186, which came with a pre-defined instructions set.
I talked to the friendly and very helpful people at Puget Systems, but they don't do water cooled. I was planning to put in the basement where it won't heat up the office and is closer to the distribution panel and its noise won't be a problem. Sometimes it is true that. "The more you by the more you save".
18:34 Everyone's gotta run free and eat sometimes 😂 Loved this video, Dave!
Thank you!
