Scanned the comments and didn't see it mentioned. MV is megavolts. mV is millivolts.
The text was in all caps
No one uses MegaVolts, kV (kilo-volt), V, and mV (milli-volt) are much more commonly used in practice.
@@Kelan-pn6em No it matters regardless.
With SI units, MV is always megavolts. There are no exceptions.
If you want millivolts you use mV.
The first thing I would think isn't that they mean mV, it would be that they are an imbecile that doesn't know what they are talking about.
@@jeffreyblack666 if you can't tell instantly from the context that it's millivolts and not megavolts, you are the imbecile
@@IamQuuick Well good thing we have these metric prefixes so even the imbecile would be able to understand.
Didn't even know undervolting is a thing. Thanks for this video!
Define what sorts of quirks are we talking about when in idle? Just recently undervolted my i3 in a ITX build using offset cpu voltage so it still can scale itself down to 0.625v when in idle while not using the original stock voltage in under full load.
Instability. Loss off Data. Not rendering results as espectet.
undervolting has similar characteristics to overclocking. when you undervolt too much, it will be unstable, same goes to overclocking too much, it too wil become unstable.
I undervolt my R5 1400 from its stock 1.25V to 1.14V and overclocked to 3.6GHz which result in better performance and less power usage.
Quirks such as?
so erm basically you are saying in a long and windy way.... you have no proof that undervolting is the issue.
I'm going to use this early comment opportunity to say that this channel has blown me away with the production quality and in-depth analysis of topics without any dank memes or distractions of that sort. I could watch these videos for no other reason than to enjoy the music and overall style of your work. So thank you, this channel is a breath of fresh air and I just wanna keep breathing!
Thank you so much for the kind words!
So true. May you gain many more subs, like you deserve!
I agree, you got really high quality so far. =)
I started subscribing to you with this video.
Luredreier Thank you man. The quality will only get better as I upgrade my camera equipment 😁
Jason Swanepoel I totally agree. I'm glad that I found this channel.
Slight overvolt overlock in winter, slight undervolt underclock in summer. That's the way I roll.
My 8350 stock voltage is set to 1.42. I don't know whether to be impressed or scared.
hows the summer in the room
Ak47 it gets warmer in the room? :O
Too bad winters are warm too, here in Spain.
First comment where I really see someone using his brain haha :)) Really good tactics for the cpu!
Dude, I have an HP Envy with an i7 4720hq. While rendering one of my own blender scenes with turbo boosting turned off(cpu running 2.6Ghz), I will reach 82-84c with a zero offset voltage of 0.885v. I offset the voltage by 0.1v down to 0.785v and the temp dropped to 69-71c, that's a 13c drop. Absolutely fantastic. I tried a 0.12 offset and it crashed..... I was hoping to squeeze a little more out of it but I cannot complain at all about a 13c temp drop.
Thank you for this video.
I was able to overclock my i7-7700k to 4.7GHz @ 1.12V. It was rock-solid stable, and silent! This is on a Asus Maximus IX Hero (Z270). I have since OC'd to 5GHz @ 1.25V , just because I NEED that 5,000,000,000 Hz... lol
5GHz @ 1.25v is nice, I could imagine you have decent temps at that voltage.
5GHz + 1.25V + 100% AVX CPU usage + 100% fan & pump speed on Corsair H100i V2 = 85C max
I would love to delid and not need such high fan speeds. I really shouldn't have cheaped-out on the cooler.
dang... lottery winner if you can run 5ghz at avx load 100% stable what test were you running prime small iff or ibt max?
Aida 64 , BOINC, ibt, with integrated GPU running fur Mark at 1400MHz
man that thing is a beast for overclocking as IBT maximum takes a good bump in vcore for me to get a passing score i can run it without blue screening pretty easy but for it to pass a 10 run sweep at the max ram i can give it it ussaly need a good +40mv tp 50mv over what i can pass on rog real bench. quite an impressive chip you got there to handle 5ghz under avx on ibt as most need an offset for that
the most important cpus to undervolt are those in a gaming laptop.
What bout for work and web browsing
@@itwilsonboiii4789 unless you render videos or work in photoshop or something it’s not something you’ll notice
Oh ok phew
Agreed, Laptops really need it. Makes a big diff. Great video BTW !
Dude thank you so much! I watched this video before and just recently built a system that used this perfectly. I have a 2600x that was ramping the fan up like crazy and spiking temps along with fan RPMs. When I pulled up HWInfo I noticed that the vcore was ramping up to 1.45v!!! I set the vcore to 1.2 with an all core clock of 4.0ghz and it was whisper quiet! I'll adjust clocks up to turbo and see what vcore is required. Made an INSANELY loud system run smooth as butter with much lower temps
Im gonna save you 5 minutes of your life.
*Yes you should.*
The products should just be undervolted by default tbh
@@TheTrainMaster15 it's not, because processor manufacturers want the CPU to keep a stable clock speed and heat while the voltage is at an equally stable level while yes undervolting is helpful leaving it at stock makes sure you get the rated performance at all times with any problems 99% of the time
@@gabea6275 its silicon lottery, I can magically put -0,2 on my 6700hq , that's a lot, and my laptop heat dispenser loves it
thank you sir, I had my doubts earlier.
thx mate
I never realized you could achieve such a noticeable benefit when undervolting. I'm definitely going to mess around with this later in the week.
The 'Auto' bios settings tend to overvolt things in order to guarantee stability.
that must be whats going on with my computer
@@fortuna19 On laptops especially its a pain. Temp difference can quite high. If you got a golden chip undervolting could even reduce temp by 20 degrees in some (rare) cases.
undervolting cpu voltage on laptop gives me about 30 minutes more battery life. dell inspiron 1440
Awesome quality. I see you are on your way to 10k. All you need is a few months...
300k
Damn, your videos have come a longggg way. Well done mate, keep up the fantastic work!
I love undervolting! In my office were running Ryzen and Epyc platforms and undervolting has overall made our office cooler, quieter and much much more pleasurable. For most of our work 3.4ghz is plenty and if it isn't we can offshoot it to the server. We were able to drop the voltage to 1.1v on a few lottery winners and 1.18v-1.24v on some others. Cool temps! With some systems with Noctua NH-D15s, full load temps could be well below 60° at full load for 10-20minutes at a time. This is better than overclocking!
This is great! As a laptop user this is extremely helpful. Running on a Intel i-7 9850h clocked at 4ghz by laptop manufacturer. Managed to undervolt 125 mV stabily and now I no longer have heating issues, thanks.
undervolting is the holy grail for laptops, especially compact ones.
i have an alienware 17 r3 with 6700hq, it ran at 1.2v stock, i managed to drop 135mv fully stable with it and i got much quieter fans AND 10c off my load temps across all cores.
Best thing about this is essentially risk free, and very very easy to do with throttlestop or xtu
I dropped my my 6700hq by 150mv and knocked almost 10 degrees off my temps.
Can i undervolt the CPU if i have overclocked the GPU?
Yep, and if the GPU shares anyway heatpipes with the cpu it will help the GPU stay cooler at higher clocks.
@@seanlacroix Nice!
@@seanlacroix may I ask what application you used? I got a predator 15 and tried the msi program based off the recommendation oglf the internet and it doesn't even let me adjust the voltage of anything, not even the fans
Lovely video. =)
This is especially relevant now with AMDs processors out there.
AMDs old Piledrivers loved both undervolting and underclocking and you'd get a significant improvement in performance pr watt in both cases.
I don't know exactly how well Ryzen tends to respond to undervolting, but I know that if you *also* under-clock them you'll get significant efficiency gains.
ryzen undervolts well for my 3600x undervolted and base clock adjusted (wont ramp up in clocks) that was to agressive on amd original settings, i dont know if the voltage or the clocks set to high original, but since i've put my own clockspeed @ 4.2 ghz and lowered the voltage (srry don't know the numbers anymore) its stable since no bluescreens anymore..
Content is spot on and the production quality is top notch. No corny jokes or stupid sponsored ads...:D
You can also undervolt and overclock your cpu at the same time, to balance temps from the overclock. My 3770 (yeah, non-K) at stock of 3.9ghz and 1.365v would idle at 27c and cap at 67c at full load. I've been running it at 4.60ghz and 1.185v for years now, never seen it go any higher than 65c at full load. Since day one, I'm using the stock heatsink but swapped out the crappy 1600rpm stock fan with a NIDEC 80mm fan that rolls at 7800rpm tops (never goes over 3000rpm though). You can also lower CPU PLL from 1.80v to something like 1.60v, and that too will lower your cpu temps.
I undervolted my i3 4150 and intel HD 4400 , after a lot of cpu stress test and gpu benchmark I found the right voltage offset , now my cpu runs at 56 degrees at 100% stress load , before it was hitting 72 degrees on stress test .
CPU and cache voltage offset :-134.6 mv
iGPU : -105.5 mv
Now runs amazing same performance but at different temperatures, I forgot to mention that my iGPU was overclocked
Thanks for the video.
Very great results!
I undervolted my surface pro 3 and my SFF PC and get a great reduction in heat and noise. the SP3 was mainly for heat while my desktop was for noise reduction. great video!
Damn, that's a great idea for the Surface. Thanks for watching!
I just got a used i9-11900k for 120$ installed on my Asus B560M-A HTPC rig, turbo boost disabled, vcore set to static at 0.905V, (all cores synced at 3.5GHz) Coolmaster g100m low profile air cooler, running very stable with more than 50% performance boost compared to my older i5-11400 CPU. I can now go withnextreame settings in MadVR w/o any frame drops as with the i5-11400 (I have 16GB DDR4 RAM xmp-1 profile). Best 120$ ever spent.
So undervolting can be used to run your system cooler at normal clock speeds or even slightly overclock without increased heat in some cases... good to know. It's real nice that this guy cam discuss with enthusiasm more than one type 9f optimization.
A very good and very sensible video, I understand gamers in the pursuit of maximum performance but there are a vast number of tasks where continuity and reliability matter. I regularly process video with ffmpeg that uses all cores and threads and you want stability and reliability over peak performance.
A very interesting topic for discussion. well done!
i got ban from live stream chat, he asked how to reduce heat, so I recommended undervolting, and his fans say don't it's gonna fry the CPU, then he was like "YA BRO I AINT DOING IT TROLL" I'm just speechless
Who?
Henrry The Gamer this streamer name Antt, he’s using threadripper yet doesn’t know shit 😂
Thanks for the good video and explanations mate :) I wanted to know if undervolting has an influence on the performance or something. Now I got the answer: No. As long as I don't change the clockspeed/multiplier and just change the voltage of the cpu/vcor downwards, the performance will stay the same.
Hi! I am the guy requesting help with a
Silent build under the last video. This video really helped me figure out some stuff before making my purchase. Just wanted to thank you for the immense effort you obviously invest in your video! I really think you will blow up and become really big if you keep at it with the same effort!
Exotic Butters Thank you for the kind words! Glad the video was of help to you.
I underclocked my 8350 for fun one day. cant remember the voltage but it was much lower than stock @3.5, with only 2 cores running.
I did this for certain games that dont require a monstrous cpu. It ran great, low temp, no noise (with evo 212).
I only used this underclock for a few days so i forgot about it and played GTA V. Loading was incredibly slow but once in game there was barely a noticeable difference.
"why is it laggy tod... o yeah. only 2 cores."
All Aperture Science personality constructs are designed to run in apocalyptic, low-power environments of as little as 1.1 Volts.
Val i have an i5-7600k overclocked to 4.2 ghz at 1.095v
this is the most useful in laptops
So smart!!i didn’t know it could happen never tried it before I am always driving my cpus over the stock voltage just because I can and I don’t really care if the chip dies..but for home theater setups or just a daily office pc that would be nice because you can save on repairs (maybe)!!
I undervolted my Alienware 13 R3 i7-7700HQ by -140 mv (stayed stable throughout all stress tests). It used to reach temps of 94 degrees Celsius during heaving gaming. Now it maxes out at 80 degrees! It was like buying a new laptop. Another thing is that the GPU temps are now much lower too. I think it might have the same heatpipe as the CPU or something like that. It used to reach 87 degrees.. now it maxes out at 80. Idle temps also dropped from 54 to 42. My battery life was also increased by around 45 mins. If you haven't done this yet, go do it now..
Nice video and interesting data. Almost seems like engineers have taken a lazy safety margin above the bottom instability point and are operating in a higher wear area maybe even.
keep up the great work! I hope to see your channel keep growing because you don't just appeal to the super enthusiast pc gamers you actually appeal to everyone.
You can TOTALLY undervolt your locked Intel CPUs. I built a SFF PC for my bro about a year ago with an i5 4460 in a GA-B85N- Phoenix motherboard, and the Arctic Freezer 11 LP I bought for it was a bit too loud, so I undervolted the CPU in the UEFI. I was very easy. 100% recommended.
Yes, you should, especially if your cpu fan gets really loud, the temperatures go insanely high, or if you are on a laptop.
this is a very nice tip... undervolting CPU will allow for less power draw, noise and temp.
Too bad Intel locks their CPUs so i3 mini itx rigs (which would be great candidates for undervolt in mini-itx rigs) are out of the question.
I do not know how well would it work on AMD Ryzen 3s, and i have my doubt about if there's a need to turn off any turbo technology on the CPU in order to gain stability when undervolting (that will hurt performance). But since most CPUs have a safety overvolt in order to work with any shitty PSU, i think there is a chance of reducing voltage (at least a little) on any CPU if rig allows. And that's not only for new tech rigs, AM3+ FM2 and any older LGA from both intel and amd can be undervolted at least a little
This channel reminds me of the cold fusion channel!
Undervolting is even more crucial in laptops where the size of the heatsinks and fans is very limited. Therefore if the CPU runs cooler the clock speed can get even higher (closer to the stock speed) since the system do not over heat at all even under heavy load like 4K rendering. Also your CPU drains less power and therefore your you can squeeze a bit more operating time from your battery.
I have a i7 6700 and it runs with core voltage in 0.990V. I did undervolting and I recommend. I never saw my chip overcome 49 degrees, even at 100% for hours!
on a desktop if definitely wont hurt, but with a laptop all it does is help! you get cooler temps, quieter fans, AND better battery life. i added over an hour to my laptop with 150mv undervolt
I Hate overclocking and therefore this is Exact what I was looking for, Thank you very VERY much :)
very nicely explained. thanks.
Awesome !!!
I'm impress by this channel, subscribing. generic channels always offer bleeding edge tech, I'm interested in efficiency.
Great idea for the tiny dan case a4.
My personal Intel Celeron laptop is fully Locked and I can't undervolt it at all, even on Intel XTU. 😭😭😭😭
But Wait!!! One day, I was going to Mom's office because there are no one else at home, and then I suddenly found an empty unused PC there at the Office!
Unfortunately it had a spec of a potato, with a Pentium G3620 (Dual-core 3.3 Ghz) & 2 Gigs of DDR3...
But the fun thing is that I could install Intel XTU with no troubles at all!
I tried to undervolt it to the limit, as most kind of people do, and I started from -55mV and keep moving down every 10mV to -65, -75,...
I was suprised that I could put it down to -150mV!! Moreover, the Maximum voltage at stress test is now only at 0.947 volts, which is pretty low on a desktop CPU...
I finally stopped at -195mV @ 0.895V since it crashed after 30 seconds of stress test. So I turned it back up to -135mV.
But -195mV is a really massive number on the CPU world, and moreover, this is desktop CPU!!!
Note: using Intel cooler
I use amd overdrive for my amd A10-5750m processor base clock at 2.5ghz with 0.88v 2.8ghz with 0.925v 3.2ghz with 1.050v and 3.5 with 1.187v.
Temps and ghz before around 90C and throtheling at 1.49ghz. Under load.
Temps and ghz now around 75C and turbo at 3 up to the full 3.5ghz! From zero to Hero!
MSI laptop btw
Actually, I believe that undervolting CPUs and GPUs, while remaining stable, could possibly increase perfomance, as your getting lower temps, which means clockboosts will be more agressive :D
It actually does by almost 250%
I actually did something like this with my R5 1600 since I got it. 3.2-3.6(turbo) speed, 1.118-1.4V vcore, which is waaay too much for the turbo mode. So I just manually set the whole thing to 3.6 ghz on all core and fixed the vcore at 1.2V - speed is way better, temps are somewhat cooler, and the most notable part: I measured 82W total system consumption while watching a 1080p60fps youtube video on default, and by fixing the vcore it dropped to 71W. Pretty neat.
have you tried an oc at 1.35v?
I have a pavilion gaming and it was going 95, 97 and even 99c sometimes. After undervoting I am now sitting around 77 to at most 83c for even the most demanding titles.
Edit: that's the cpu not gpu. Cpu seems to overheat much more than gpu in my experience at least.
Super helpful. Thanks :D
i actually did that with my 4790k, 4.4Ghz 1.21v, at stock it was pushing 1.32v at the same frequency
In my experience, Undervolting is way more effective and safer than overclocking. Every time I overclocked my CPU, I experienced Blue Screen of Death (BSoD).
Yeah same, when I finished putting my brand new PC together and had a successful post, the default motherboard Intel CPU settings were on Turbo Overclock, didn't notice until I got a BSOD mid game.
I would suggest overclocking as much as possible at stock voltage if the CPU is well binned, thus overvolted from the get go.
I have nvidia rtx 2060 and i just went down from 1.1375V to 0.95V. Temp on stress tests dropped from ~48C all the way down to ~37C. Maintained stability. Thanks for the advice ;)
i love your vids
I undervolted a socket A 2400+ with an overclock to 3000+ speed 15 years ago max temp under load is 38C and still running perfectly
Great video, you can do the same thing for you GPUs as well. I got HD 7870 running that should be 1169mv 1000/1200, I got it down to 1100mv 1100/1300 stable and even with added overclock that is whole 5C less under full load then the stock setting. So now it runs 60C max and not 65C, if I keep the stock clocks the temperatures from such a small undervolt go as much as 8C lower under full load when running furmark.
in 20 years, the kids will say, "we feel sorry for people in the past, who used i7 processor"
hihi.

Putting the CPU on the edge of a black rug to serve as a divider for the editing? *Bloody Genius*
I was able to get a 160mv undervolt on my work PC, which used to cause people to glance at me when it would let the world know how loud its fans can scream. Difference (for me) is about 15 degrees C at 60% fan speed. (Or the difference between running at 80%+ and 50-60%)
It's definitely worth noting that you're just as subject to the silicon lottery with undervolting as you are with overclock/overvolting. Though, the quality control on the 7700k is pretty good so I'd imagine most people would be able to replicate your results or similar should they want to!
Is there also an opposite of this, where you increase your clock speed as much as possible without increasing the voltage?
I bought an i5-6600K and the Z170 Platform in the thought that I'd like to get into overclocking. Have played around with it briefly once but haven't had anything consistent simply because it being stock was more than enough than what I needed it for, especially in games. I'll probably start overclocking when the 6600K starts to bottleneck other components which hopefully won't be for a fair while.
3:26 That's not how temperatures and percentages work. Don't use percentages when you talk about a drop in temperature on the Celsius scale.
Impressive that you thought of that
it should temperature difference against room temp, then it can use percentage.
Also laptops made a very good use of undervolting; 10°c reduction on mine at least
Why didn't you mention the power saving? Good for your walled and especially great for a laptop. You might get a significant longer running time if your laptop bios supports to change the voltage.
it doesn't need any special bios since 4-th gen, all laptops with core i series CPUs support undervolting via software like Intel XTU or Throttlestop
Yes, i have AMD FX 8350 which will throttle even with a good cooler. I know 2 persons who had throttle problems, even with a water cooler. I can' t imagine, why stock cooler is even added to the box :D Undervolting my AMD FX 8350 removed any throttle problems, still runs solid at 4GHz. So you can even fix some bad CPU' s, and not just get fan speed down.
You have a very good CPU. Running Heaven benchmark my CPU drew as much as 1.368 volts at stock speed [not overclocked] and it fails to finish POST at 1.2 volts. [Edit] I forgot to mention maximum core temperature was 54 degrees C.
This is Electronics 101 + or - 10% on all values. Voltage, resistance, capacitance, etc. Though with digital and precision circuits a well regulated voltage with minimal deviation from the recommended spec is obviously most ideal.
i have underclocked my 8350 with 1.28v (vs the stock 1.37) and its stable. ive done this just for cooling. so, yes this works. i would recommend it.
Just realized I've been running 20mins on Prime95 max heat mode testing undervolted temps before checking this video out :D
so overclocking with this undervoltage is safe for my laptop?
great video
I would think that someone who doesn't want to overclock, also wouldn't want to mess with bios settings to undervolt. Perhaps I underestimate the typical undervolter.
damn am 4.9ghz 1.354V stable with my i7 7700k, can't wait for delid tool to come. At stock settings its around 1.18V.
board msi z270 titanium
Albin Keranović It will most likely degrade within a couple of months if you keep it at that voltage
So you are new to overclocking cpu if you said that.
You can have 1.52 volts max on 7700k (www.intel.com/content/www/us/en/processors/core/7th-gen-core-family-desktop-s-processor-lines-datasheet-vol-1.html). If you don't want to read it all you have a table at page 114, at 116 is for intel graphic chip.
I am currently 1.375V on 5GHz after delid. Temps are now 70C max in prime95. I can hit 5.1GHz after delid, but i must put 1.48V to get it stable (prime95 86C max), so its a poorer chip, some can get 5.2ghz at 1.44V. So i have backed up because its a slow boost 100mhz for that much more voltage.
1.52V is apsolute max for 7700k, so its not safe (its like living on edge), but everything belove 1.5V is ok if you can keep temps belove 85C.
Above 90C 24/7 will degrade your intel 7th generation cpu, but very slowely 2-3years maybe more, it depends on certain cpu, every cpu is different, and depends what are you using your cpu for.
I had fx8370e at 4.8ghz at 1.5V 24/7 (max temp 55C) for year and half, no degrade, every bench test was equal all the time, now my dad is using it, everything works as it should be.
Btw you must have a great motherboard so the power delivery and vrms can keep up. Only poor motherboard, or faulty motherboard can degrade your cpu at voltages lower then 1.4V, if the temps are at normal lvl.
I will contact you in couple of months if everything is fine with my cpu, so that people know for sure. ;)
Albin Keranović so how has it gone?
49ghz @ 1.35 for me I see no point to delid
@@hasanenhaider1060 they have water coolers that go straight onto the processing chip under the lid that keep them icy cool with massive overclocks.
Bro undervolting helps at long game sessions.
Yes it does I just got into pc gaming with ryzen 7 4800h and rtx 2060, in winter when we have like under 30c and as low as 19-24c at best, it was pretty good being able to keep its clocks nice and high, but now it's summer with 35c+ to 40-42c temps and lowest 33c, it was struggling and so I disabled the turbo (did not want to install ryzen controller) since I only play very GPU intensive games or games like valorant which give 144+ fps while cpu throttling anyways, it's pretty good under 85c most of the time. While boosting it almost immediately reaches 95c, but you gotta give it to those ryzen chips man, at idle it's literally averaging 45c it's crazy like just 8c over the ambient.
@@Varad13Plays 85°C - 100°C range is pretty damn toasty for those Ryzen chips my dude 😬 they will definitely start thermal throttling with that range under load. Try everything ya can to get it cooler!
@@TheNightKing22 chips are rated to not throttle till 105c man and asus has done a bad job with its cooling, I am going to cut vents into the bottom panel and add some copper heatsinks on, replace the thermal paste then it should be better
@@Varad13Plays well you're right the actual limit for the 4800h is 105° but it does depend on which chips we're talking about where they actually start limiting. Still! CPU and GPU dies are not super stoked to be running close to those Temps, and in theory could shorten lifespan of course. Are you running an air cooler?
@@TheNightKing22 no its a fully custom loop with a 360mm rad
I’m not even joking I won the silicon lottery got my Ryzen 5 2600 from 1.13v at 3400mhz base clock to 0.95v did multiple stress test like Aida64, blender renders, unigen heaven 100% stable. I also undervolted my gpu from which has been factory oc rx 5500xt btw from 1145mv down to 1045mv
Bro thats awesome
amazing channel. great quality :D subbed and liked. Watching all videos now. They are really varied and interesting to watch. Keep it Up! next big tech channel :DD
you should always have the lowest possible voltage for you desired cpu speed, so the answer is always yes.
for noise consideration you can run a 6700k at 1.28 volt with a noctua d15 cooler at 800rpm with no cores going over 70c.
so i think any of the 2 latest cpus from intel can be cooled quietly with an overclock.
Personally I run an i5-7400T with 16Gb of low voltage ram and an SSD with an LCD screen. The entire system is under 90W. Most CPUs take that on their own. Needless to say the fan on the heat sink (which is designed for a 95W CPU) rarely gets above idle speed.
AMD Phenom II 965 BE C3 stock 3.4ghz 1.376v daily use undervolted 1.264v and 3.7ghz oc 44c full load temp or i can undervolt to 1.312 and 3.9ghz 51c full load temp. it's a thing for me from 2010. Only Ubisoft(Denuvo) with Far Cry 5 and AC Origin force my hand to upgrade my golden chip to newer gen because lack of SSE4.2 instruction set otherwise i can play all released games and enjoy not just play to date with 8gb ram and a gtx 970 at 1080p at high settings or above some at ~40fps some above 60fps but usually i use adaptive vsync to get rid of screen tearing so 60fps with neat details its more than enough for my ancient tech.
The logic is straightforward: if you're able to overclock without touching the voltage, then you're able to undervolt at stock clocks.
I undervolted G4560 from 1.032 = 60°C (BOX intel cooler) to 0.971 = 54°C and I can do more but now it is stable :)
Even more important on gaming laptops...even though the CPUs are not supported
what do you mean not supported? all core i series laptop CPUs are supported since 4-th gen, and undervolting is super efective on them since 6-th gen
Ahhhh. Definitly a hidden requirement for all gaming rigs or laptops.
alienware 17 r4 7700HQ @3.4ghz from 87c down to 70c at max temps.
It's super weird to see MegaVolts related to ordinary CPUs...
Millivolts are with lower case m. Upper case M is for Mega SI prefix.
My 7600 survived the Prime95 with a 150 mV undervolting. However, it crashes occasionally at idle. Thus I only got a stable 100 mV undervolting.
I think this is the drawback of an "offset" undervolting. 1.2 to 1.05 is fine. 1.0 to 0.85 results in crashes.
My 2014 Macbook Pro laptop I have to undervolt and run custom fan profile to avoid constant overheating when playing computer games on it... With under volting it can run full 3,4Ghz boost 100% of the time with all 4 CPU cores at full load :) Without the under volting it overheats and throttles CPU speed down badly just from running GTA V at 40% CPU load usung GTX 980ti external graphics card...
i have 100c my thermal paste i changed yesterday and my fan is working perfect
I've done this, i have a 7700k and a MSI Z270,
I was putting in auto mode running in stock Ghz, that turns to 1.288 on Vcore... my cpu was getting 80-85 Cº on full load... So now i set the vcore on 1.118 and Load Line Calibration on level 3 (that's push to 1.160) and my cpu now only reachs 65cº its a huge difference... and also its not delided
I did this with my Haswell laptop 2 years ago, when I disable the undervolt the cpu will start overheating and thermal throtteling.
I have -80mv and it helps so much.
Yay! Someone that mentions undervolting :)
This video fucks my eyes more than Depth of Field
Got a 9900ks.i leave it @5ghz and lowerd the vcore.tested with aida stress fpu ,stress cpu ,stress cache all at same time! vcore bios 1.24volt static and 1.19 under load!Stable
