Linus was right.

Buy NEMIX 32GB DDR4 ECC RAM (PAID LINK): https://geni.us/Hf9H

 

It’s possible to use ECC server RAM inside of your regular desktop computer at home, but is it something you SHOULD do?

 

 

 

[IanCutress]

Just to add this in, as it wasn't included in the video.

 

AMD's ECC for Ryzen is not POR (plan of record), which means it isn't post validated. A system can very well say it's running ECC, and it'll show in the options that ECC is running, but that doesn't actually tell you if ECC is enabled. The only way to truly see if it's enabled is to force a bit-flip and see if it catches it.

 

I responded to Torvalds' thread on RWT with this info at the time.

Secondary, DDR5 has ECC per chip, not per module. It's quite a different and important distinction designed mostly for the memory cell reliability than correcting errors. Most DDR5 for consumers will be non-ECC, and ECC variants of DDR5 still require that 9th chip to enable true SECDED support.

Using a parrot to censor Linus' finger.

Nice.

After watching this, didn't you think that either referencing old research on the frequency of Bit-Flips or even running your own experiments was worthwhile? 

 

I'd be extremely curious on how often this actually roughly happens in a modern machine. I have no Idea as I expect not all Bit-Flips would result in a crash.

 

Because references go up to 4 Bit-Flips per day

That seems rather significant...

If it's so important, why not just use mirroring instead of parity?

Because that would increase cost and reduce performance further, while parity achieves the job well enough already?

I get an average 3/4 bit flips a month on my server and the only reason I know is because I run ECC memory on a btrfs raid array with check-summing enabled.

wait, you reference the legendary Torvalds clip but you have an nvidia card on screen the entire video???

 

how did nobody involved in making this notice that?

Registered specifically to thank you for the link. Always amusing (and informative) reading what Linus (the grumpy programmer one) has to say.

[Dutch_Master]

Someone recently mentioned in a comment somewhere, and I'm starting to notice myself now too, that LTT is more and more focussing on "soupa-gaimahs" stuff. Please don't. I for one don't care about gaming (at least not the way some fanatics respond to this info), but by'n'large tolerate it as it's bleeding-edge tech. I'm sure I'm not the only one. Do more non-gaming content, if only to keep your audience diverse.

 

TIA!

 

Your audience

so it's a little more resilient than non-ECC RAM, but not the ECC anyone expects for servers and scientific computing? o_o
how much less should i worry about errors with the non-DDR5 generation compared to non-ECC DDR4? or rather when should i start worrying about errors in general? (outside of those dealing with finance or accurate results)

 

just to describe my headspace at the moment: after watching the video i kind of decided to drop all my curiosities with ECC on DDR4 and relegate that to the DDR5 generation, and then i've learnt (here) that it's kind of not the full ECC I've had in mind

 

writing as a student in 3D media with a personal threadripper platform, still kind of gauging if i should set aside some eventual curiosity money on ECC RAM. haven't gotten any luck from XMP for a long time (which i think isn't recommended if i prefer stability?)

Check the link I posted on how AMD systems potentially say that 'ECC is enabled' but it's just a register check and there's a chance it isn't actually enabled unless you test for it.

[Radium_Angel]

Registered ECC for the win!

Sorry, this is some next level bullshit, LMG.

 

Thumbnail: Famous image of LT giving the finger to NVidia

First frame of video: Article of LT saying "F-K you NVidia with said image from thumbnail

 

Video content: Nothing to do with NVidia at all.

 

The line between "appeasing the algorithm" and "actually being disingenuous for clicks" is pretty goddamn thick.

My biggest takeawak from this thread is WTF is going with that profile pic of James? He looks possessed.

Because LinusT flipping the finger ain't just about nVidia. Sure, he made it while commenting on nVidia but he is also pissed at Intel for this very topic of the video. I'm sorry you weren't well read enough and jump to conclusion based on a thumbnail and lack of knowledge.

Am I missing something here?! What does Linus Torvalds getting angry how nvidia refuses to work with him on Linux drivers, and Intel disabling ECC on consumer chipsets have ANYTHING to do with eachother! I mean I get it both are things that Linus Torvalds got angry about, I know nvidia used to make MOBO chipsets, and I know that these companies are not AMD.... But what do these different topics have to do with each other? I clicked on the video expecting a rant along the lines of "NVIDIA HAS DONE IT AGAIN!" rather than "Linus Torvalds Fbombed and flipped the bird to NVIDIA years ago because of drivers. So because of that, let's talk about why Linus T is angry at INTEL because of ECC!"

But that image is only ever associated with Nvidia, there is NO way LMG would not have used that image KNOWING this. There has been a lot of hate around NVidia for quite some time now, so it wouldn't surprise me if they used this particular image as "well it's Linus, but people hate NVidia a lot right now, so if we keep it vague people will come to our video thinking it will be more things to beat down on NVidia for"

So use a different image of him. it's not like the image they used is the one and only image that exists of him

you're right, i'm not "well read" about it, because i think Linus Torvalds is a colossal bag of dicks and I put all of his words and anything he says in the same pile as 98% of twittter, 100% of 4chan. (see: rambling of insane people who i do not care about in the slightest)

I actually followed this thread when it came to the news, and I still find the thumbnail and title to be misleading, I clicked in the video thinking it was going to be about nvidia for some reason.

[Superio]

A little bit Meta, but does anybody know the name of the second background music track from the video? I really like it.
