Ah yes, ye olde bribery.
Wtf that’s repost someone has already said it on another video
Another great thing about ECC memory that if there is a problem with one of the memory sticks the computer can still boot and give us information on which memory slot it is.
I feel like thats something that should be available to every commercial ram, which is very unfortuante if its really just on ECCs.
Thatd been AMAZING! Took me a LONG time to figure out which stick was bad i had…would crash only once a day
ECC memory should have been implemented on personal computers by the late 1980s. It would have made microcomputing a couple of orders of magnitude more reliable, but only slightly more expensive.
But again, intel
Nonsense, computers are unreliable because of shoddy software.
ECC saves you from one crash a year at the very most.
I have ECC on my machines because I work with big data-sets.
Yet all my programs crash just as often as on any other machine.
@@lrrrruleroftheplanetomicro6881 - It is _not_ "nonsense" and is readily testable. Re-run the program under identical conditions. If it fails reliably in the same way, it's a program bug, but if you can't reproduce the crash, it is most likely a soft error that could have been caught and corrected by ECC. A soft error may not even cause your machine to crash, instead producing incorrect results, but if you are unaware of it, it could have *_deadly consequences._*
@@Milosz_Ostrow Dude, as I said, I use ECC myself. And I still see non-reproducable crashes all the time. Complex software has a tendency to do that. At the same time there's millions of macbooks out there that never reboot and still don't get bluescreens.

My RAM has, like, 10 clocks. One clock is for the proles.
Actually No ECC slows down over clocking. If you poorly overclock ecc memory it's gonna cut its speed in half because it's spending most of the time fixing all the errors you just caused. ddr5 in die ecc It's hard to check if it's airing so the only way you can check it is to check the latency.

Having had workstation servers which always had ECC and DID fix some data corruption, I made sure to order ECC memory on servers.
Unfortunately not all boards/CPUs supported it.

You can push the timings on ECC way past what you can with normal RAM, so you can actually get the timings lower with ECC. Of course, you'll be pushing them into failure and consuming their ability to correct errors in the process.

Agreed. Fucking linus bait tips
IKR. Just as I thought Linus is going to blast how NVIDIA is bad to Linux desktop users.
Yeah for real, he is right, sure, but what does ECC memory have to do with NVIDIA?
I'm running my R5 3600 with 64GB of micron single rank ecc ram.
One more advantage to the stability is, that it runs 3200Mt/s at 1.2V and stays perfectly cool without the need for heat spreaders.
The standard voltage also has the advantage, that it runs the 3200Mt/s stock without having to use D.O.C.P. .
And it might be more gentle to the cpu's memory controller.
Ram never needed heat spreaders, it was just a way to upsell you
Ram heat spreaders are unessecary for modern memory. It only is really needed with DDR2 FB-Dimms used on the LGA771 (not 775) Platform, these requires active cooling and heat spreaders. Some modern server dimms such as LR-DIMMs or Rambus RD-RAM used on the first generation Willamette pentium 4s. Head spreaders and active cooling isn't needed for consumer DDR4 memory modules.
on servers, other than reliability ECC ram is also a security feature, with the speed of modern networks, remote rowhammer exploits are pretty much possible

I'm so glad you posted this video. For YEARS i have tried to explain why (or why not) someone would need ECC, and what the tradeoff is between these two memory types. My first encounter with ECC was a Slot-A motherboard BIOS. It allowed the user to turn support on or off. However, back then a 700MHz. system took heavy hit by turning this feature on, and ECC memory was out of reach by most of my home computer customers. Funny, how this subject comes up again.
ya, back in the day ECC / hamming was slow, you still stop operations, a full ram stick test is insane long (you really need a ram checker). I never saw the benefit. Unless someone invents hot swappable ram, I'm not blowing my brain over it.
@@carlynghrafnsson4221 Large-scale mainframe computers use redundant memory, where you can rip one RAM stick out, and the system will keep chugging along. These mainframes then form a cluster, where any node can be turned off, while all other nodes stay working. Skynet?😁

Professional streamers could probably benefit from having ECC memory, just to reduce the number of crashes then get while live. And hopefully to keep the OS from corrupting in the long term, from misplaced bits. Because having to take days or weeks to fix a computer is bad for business.

want the utmost instability? dont mind losing a few FPS? then go AMD! 😂
It can also be read as ‘the utmost in stability’ which is probably what he meant. But it’s funny how two sentences that sound exactly the same can mean directly opposite things!’
@@dalehorton7748 Sorry, but AMD ain't about Zen(1) on early BIOS anymore.
Zen3 is better than Intel in most games (stock or max-stable OC not really any difference) and uses less power while supporting PCIe 4.0 and ECC. Suck it, Shintel fanboys!
Funny anecdote: ECC was/is actually possible on socket 1156 with normal i5's. Sandy Bridge to my knowledge removes this option unless you use Xeons and with newer gens many Intel boards don't even support Xeons at all. How do I know? Well, let's say I've gotten one of those chips for free and bough a "cheap" (considering the age and nun-functional overclocking not so much) €32 server-board to play with it. The board does not boot with some (or all non-)ECC UDIMMS and the manual says so. I unsuccessfully tried many different variants of non-ECC, but with some random cheapo eBay UDIMMS it does work fine with 16 GB total on the cheap. Obviously only the Xeons support RDIMMS though.
Another personal story, skip over if not interested…
I tried it, it was great for raw performance, but man the 1700 I liked nothing more than not working, especially when overclocking it to levels an 1800X should run stock. I mean who need more than 3.7 GHz at sensible voltage anyway? At least with 7 nm Zen I had decent luck with my 5600X probably (not fully tested yet) doing 4.7 GHz allcore ~1.3V and even more insane (considering the older architecture and lower SKU) I have a 3600 that does 4.6 GHz all-core @~1.37V fully bench-stable and at "safe" voltages it does like 4.55 GHz - could probably play most games @4.625 GHz even (talking about instability).
@@ShawFujikawa I realized that was the intended sentence, but his pace and cadence allowed for this misinterpretation. A minor offense for sure, but an error that could have been caught in scripting.
Whoever typed the CC needs to learn the difference between "parody" and "parity".

It’s worth noting certain filesystems require ECC memory. ZFS is quickly becoming a go to choice in the NIX world. I’d guess this is partly why Torvalds was so bothered by the decision.
Not actually true. ZFS is no more susceptible to bitflip issues than any other filing system.
@@joshuapettus6973 Yes but ZFS gives you file reliability guarantees no other filesystem does.
If you run a scrub: the filesystem can correct any corrupted sectors from backups. But if you get a bit flip during your scrub: there is a possibility that a memory error can corrupt data stored on disk.
Intel artificially locking out features to customers? This is absolutely and completely unexpected!
intel already blocked it long time back, well they are boss back in the day so it make sense to block ECC for more margin

They didn't, it's just the only explanation when a bit changes in a way that is impossible according to the code. Although the cosmic ray thing is far from the most likely source of a bit flip, there's also other background radiation, faulty memory or just normal electromagnetic interference.
Bits can flip in mass storage too, not just in memory. I’d love to see some videos for digital packrats on how to protect the integrity of your data
It's called RAID
@@RawbLV If a bit flips in storage and it’s simply copied over to a new disk in raid I’m pretty sure it’s just the new “bad” data that gets duplicated. Maybe I’m wrong about that though. Also, how do you maintain integrity across offsite backups and not just on-site redundant copies?

"Utmost instability", something we all strive for.
Great, I'll grab my stuff!
I'm reasonably certain much of my computer's weirdness in long uptimes comes from RAM screwy-ness. The errors usually persist over software restarts but not operating system cycles. Never been able to track them down either.
In fact, my browser suddenly started bugging out, eating 24% of cpu, and started the memory leak creep seconds after posting. Hasn't happened in a while either.
I've been using ECC in dual cpu rigs for 3D work, and some gaming, for decades. Only thing I really knew was it is supposedly more stable, but after those decades it sure seems to be true. May not be faster but in the six years with my current workstation I have never had a BSOD, or any crashes (system, games, applications, etc.) The price does suck, and a good board that supports ECC is usually more so double whammy but it seems to be worth it. Go the extra mile and get dual cpu's, then you can have dozens of cores and terabytes of ECC memory. Is that overkill?
Great video!
I think the main (minor) speed difference comes from mostly the timings in the ECC memory, a 3200 stick runs around CL22 to CL24 while a non-ECC stick would do something more in the CL16 - CL19 range. Also ECC RAM doesn't go higher than 3200 right now. (but does only need 1.2V, while most faster 'gaming' sticks run 1.35 or even higher)
Ah ECC. Brings back memories from my Abstract Algebra Class 😂
Heh heh memories
Oh fuck no
@The Mystic Fez it breaks down counting principles
ECC memory(s) 😏😏
Galois approves this comment
I'm surprised there's no law that requires financial institutions, such as e.g. accounting firms, to have ECC memory in all computers.
2:39 on rockets a bit flip has resulted in a rapid unscheduled disassembly.
5:36 Damn you guys insert that meme everywhere
copy cat
@@talkntech9707 I didn’t even see your comment
@@Herr.Mitternacht its a joke, no need to take it seriously
For those who don't understand Spanish: Linus is talking about And Yes Yes memory.
For us programmers, &&11 memory.

LA MEMORIA!!!!!!!
I have ecc in my gaming rig most stable pc I ever owned. e5 1620 -v2 , and gtx1070 8gb and I absolutely love it never a problem just works. I like spybot great for controlling bloat ware .
DDR5 WILL COME WITH ECC INCLUDED, CAN'T WAIT!!
Yay, more expensive memory!
@@rockytom5889 are you dumb? Ofcourse it'll be more expensive than the last generation regardless of ecc
@@1h3art_mys3lf- of course it will be, but it's going to be improportionally more expensive because of added features.
@@DasDieDerErik Literally its one module. Ram overall is cheap They sell it and make one hell of a profit. Those RAM chips are probably 5 bucks each. And then you go and pay $90 for it
8:35 - Yes, I would like the utmost instability please!
in stability
Oh, so that's where Watch_Dogs' DEDSEC comes from: SECDED
When secded came up I though of watch dogs 2 and couldn't figure out why lol
Nope, it is an reference to "Dead Sector"
@@SnailgamerLindo Is that so? I was just thinking that this matched the spelling a bit better but if you are right, that is good to know.
DRINK ALL THE BOOZE, HACK ALL THE THINK!
Detecting a broken memory stick is a far more important feature of ECC than correcting the occasional bit flip caused by radiation. You can have a broken memory stick for quite a while before realizing it and that might create havoc with your file system.
8:36 "But if you want the utmost instability..." haha!
I think I had a cosmic ray event several months ago. All at the same time, my main PC had texture corruption while gaming, my 2nd PC had a BSOD, and my phone restarted itself. I knew about cosmic rays but that did make me realize how much cosmic rays can actually affect our hardware.
2:23 Now it's time for bit flips brought to you by Manscaped
Can you do a video that provides an objective comparison of stability when using ECC vs. Non-ECC ram? Hours of gaming between crashes?
My home server and workstation's error logs have a list an error a year on average. Last one I see was in January. The number will be very very low if not overclocking, not using all the memory slots with high density memory, temps are under control, not living on top of a mountain, and stable power/UPS usage
Damn, reminded me of good old computer science days back in uni...
