@davidrevoy It occurs to me that if you bought your RAM in 2020 it's unlikely to be affected by demand for AI kit spiking the price of DDR5—it'll be an older type of module. So should still be available second-hand for not too much more money.

@davidrevoy oh, man, I feel you. I went through this few years ago with my 5900X platform and 2 RMAs with G.Skill. I don't have a proof, but both times it was a module that was located under the CPU heat-sink, so I was wondering if it was simply cooking (temp-wise) there, after 2nd RMA I switched to AIO, so no heat area around CPU and it worked for a few years without issues. I was going mad too when it was happening.

@davidrevoy Oh wow :( J'ai eu cette peur y'a quelques jours (PC qui crash pendant des grosses compilations, mais memtest est passé, faudra que je teste un truc comme cpuburn).Et je connais pas la durée de la garantie chez G.Skill mais y'a des constructeurs qui font de la garantie à vie donc ça peut valoir le coup de regarder.(Après vu le marché ça peut valoir le coup d'attendre un peu histoire de pas se retrouver avec une ram de mauvaise qualité)

@davidrevoy I had faulty RAM modules multiple times in my live (I used to fiddle around with PC Hardware a lot and had a lot of used PCs).The first time I had a faulty RAM module my road to discovering the issue was about as long as your (I even started an RMA request for the motherboard before someone hinted me towards memtest).So I really feel you (besides that I did luckily not have a deadline back then)

@davidrevoy @cstross DDR4 has unfortunately also significantly spiked in price, but not to the extent DDR5 has. If it's just a single 8 gig stick tho it might not be totally bankrupting...

@davidrevoy If you were in need of DDR5, I have two kits of 2x 32GiB = 64 GiB 6400MT/s that I misordered by accident just days before the price hikes started. For trusted people in the FOSS community who are in serious need for RAM, I'd part with them for a price close to what I bought them at.

@davidrevoy > I followed the memtest documentation's advice ( Troubleshoot page, "1. Removing modules"Be aware that the webpage of GPL memtest86+ is https://www.memtest.org/ the other ones are proprietary versions of that software.>Your Experience?I've been doing computer diagnosis and maintenance since I'm 14yo. This is a classic case of faulty ram .In such cases you have to test both the motherboard and ram modules.-For ram modules it's easy to just remove them one by one as you stated.-Test the mother board, to go faster I usually use other ram sticks that are known to not be defective to check as fast as possible.-To test ram as quickly as possible I put it in one or more computers.Once the tests are done, faulty are set aside and I redo it on the main for 100% certainty that there's no further issue with the original RAM and Motherboard.That aside these symptoms are also signs of a lot of things, ram isn't exclusive, it could have also been storage corruption. Bad cables, hdd pcb etc... I've seen so much I can't honestly tell someone exactly what it is as it can be anything, even the PSU can be the cause. In a recent case that drove me mad, a wireless card couldn't connect because the owner had put a magnetic sticker on a specific place of the case and which rendered impossible connections (crazy first time issue).Anyway three most important things to test from the start are the PSU, RAM and HDD/SDD/nvme.For HDDs you have both smartmontools and gsmartcontrol (GUI for smartmontools) plus badblock.For NAND based storage, there's nothing to do proper maintenance, manufacturers are extreme cunts with this tech. The only way to predict failure on these is to check the filesystem as the controller of these will often eliminate faulty pages (several bytes of faulty information) but don't update the filesystem as a result.For ext4 FS:e2fsck -DfFv /dev/sd*For F2FS:fsck.f2fs /dev/sd*

@davidrevoy Worst RAM issue I ever had was not noticeable via crashes etc. But over time I noticed broken bits in images, texts and other data that was read and written back to disk. First I thought of a faulty disk but after copying everything over the data on the new drive was even more corrupted. Long time ago but still gives me the creeps.

@davidrevoy Crucial Ballistix had severe problems with a particular batch, and I lost ram in my computer as well as one I built for someone else, and warrantied. Back when I cared about computers, I was into overclocking and stuff, and it was standard practice to memtest new builds. Some failures were due to aggressive overclock, some due to manufacturer faults. I've probably lost 8 sticks over the years through no fault of my own. 1:2

@davidrevoy Also keep in mind that it’s not just RAM that can have issues, but also the slots it sits in.Had a server-grade workstation (dual-socket, 8 RAM slots with 16Gb ECC REG DDR3 apiece). Each piece of RAM tested perfectly OK by itself in the default primary slot, but failed consistently in one secondary slot and intermittently in another. The slot hardware (pins) were fine, but something elsewhere had broke.Which is why you also test each slot, to be sure.

@davidrevoy It seems to me that operating systems could and should detect bad memory, but sadly a lot of software is built without fully taking into account the fact that hardware fails.Relevant fact: Linus Torvalds is an advocate of error-correcting memory (https://arstechnica.com/gadgets/2021/01/linus-torvalds-blames-intel-for-lack-of-ecc-ram-in-consumer-pcs/) and uses it on his own machine (https://www.youtube.com/watch?v=mfv0V1SxbNA).

@davidrevoy I've had so many weird problems caused by (what turned out to be) failing RAM, that I swore off regular RAM years ago. I've since only been using ECC modules. Luckily most Ryzens support ECC, though not all motherboards have all the lanes connected, so if you go this way in the future, check the specifications first (Asus and ASRock usually support ECC, Gigabyte sometimes doesn't).Of course, right now any kind or RAM is too expensive, so this is advice for the future.

@davidrevoy Not cool. RAM issues basically boils down to "everything's borked LOL".Although it might also be the slot on the MB that is faulty, not that it changes anything, since you use all other slots anyway.But, I didn't see other mention this: a LOT of memory sticks have a lifetime warranty. You could check if that's the case here.

@davidrevoy There was a patch for Linux that allowed the kernel to grab memory, but never use it. I can't find the link, and the first hit on Google seems to be dead.There was also a blog post at Oracle that seems to have gone away; 'attack of the cosmic rays' or some such which was neat but not relevant to hard errors.I hope your rig stays better.

@davidrevoy Wow, that sounds rough. Thankfully I've only ever had one RAM failure in my four PC builds this millennium, and when it failed, it just caused a boot issue so I was able to diagnose pretty quickly. It's good to hear about the different things to watch out for and test. I've had just about every component type fail at one time or another, save for a CPU. I've got fingers crossed that my current setup from 2019 keeps for a good while longer.

I'll try to check the conditions when I bought it, and send the defective one and get a replacement.

@vvelox Thank you for the feedback. Good to know about aging, as I was fearing a domino effect as all my RAM modules are around the same age (almost 6 years).For ECC, it's a big 'TIL' after publishing this article. For sure, I'll be interested into this a lot from now on. A defective non ECC RAM feels just too dangerous for my work now.

@rekabis Good advice, thank you. I guess I accidentally tested a lot the first slot (the one with the defective RAM module "A") because I tested all other RAM modules B, C, D with this slot after. So; at least for this slot; it's safe to conclude this one is ok. But I'll keep that in mind in case I have another one who go defective.

@vfrmedia hehe, he was a bit angry to me that I chased him to not go inside this box on the desk. 😅 And then, when I called him while taking photo, he was looking like: "eh, what now?!" 🤣

@elly Thank you! Yes, I read about BadRam: https://www.memtest86.com/blacklist-ram-badram-badmemorylist.html , I'll probably try to play with it if I can't send back the RAM module for warranty. I'll try to play this first, as the manufacturer announced lifetime warranty on them, and I still have the invoice.

@datenwolf Thank you for the offer! Wow, what you misordered back then is now worthing more than gold. See here https://www.ldlc.com/fiche/PB00544141.html ; 1379€ , unbelievable. But I'll try to play the warranty first on this defective module (or maybe G.skill will ask the two because on my invoice I bought them two by two). My motherboard can only handle DDR4. The price for DDR4 has doubled, and, on second hand market, I can still probably find a replacement for around 40€. But thanks a lot again.

@davidrevoy @nuculabs Are you sure - I see you're using a Ryzen? My Ryzen 3950x can do ECC; AMD ones often can - whether your motherboard can I'm not sure.(I bought 2nd hand ECC server ram from a refurb company about a year ago; with ECC I'm less bothered about buying 2nd hand)(It really feels like you should be able to draw a broken Ram)

@davidrevoy You're welcome!Maybe you should check the filesystems after running days with bad ram:1. Backup!!!2. Boot once with kernel command line parameter fsck.mode=forceThis took just a few seconds on modern systems. Check the result with journalctl -u 'systemd-fsck*'ECC is an expensive feature but standard for server hardware. They know why.And for new Hardware: run memtest for one night.

@penguin42 @nuculabs I'm not 100% sure, but from what I read of my CPU, a AMD Ryzen 7 3700X (not a pro one, Matisse architecture) then the spec of my motherboard: https://www.asrock.com/mb/AMD/B450M%20Pro4/index.asp#Specification it looks like only the "PRO" labeled CPU in this products can benefits of ECC.

@davidrevoy OMG, yes, this kind of failure is just crazy-making, when many things crash, and the system just seems unstable... I had that happen last October. It started with occasional Firefox crashes, and then at some point, I got build failures for Inkscape, which I thought were Inkscape-related. Asked our devs, and they had never seen that kind of error, so I thought it could be the RAM - and it was. Used memtest, too. Unfortunately, it was the built-in non-replaceable RAM that was broken.

@Moini Exactly, now you mention it; I saw a tab or two crashed on Firefox on Sunday evening. I thought: maybe the code from Youtube or Protonmail and a bad Firefox version, this will pass. But now I'm thinking, it was already little signs about the RAM going more and more defective.

@davidrevoy En attendant de changer la barrette de RAM, il est possible de dire au noyau ( paramètre memmap ou via GRUB_BADRAM ) d'exclure les zones/pattern défectueuses reportées par memtest ( si les erreurs concernent toujours les mêmes plages d'adresse et sont "stables" )

@davidrevoy @nuculabs My reading is that line in the spec is only for the APUs (ie. the ones with the onboard GPU). I believe my 3950x is also a Matisse, and I'm on the X570 Pro 4 motherboard https://www.asrock.com/mb/AMD/X570%20Pro4/#Specification which has the same warning.

@davidrevoy I’ve had bad ram enough times to know the signs as soon as you started to describe the problems.There’s no real solution to avoid them going bad - if a stick has been running well for years it’s usually a manufacturing fault if it dies. But now that you know what to look for, if it happens again you can recover more quickly 🙃

@davidrevoy @elly Thanks to share your experiance.If Linux is unstable, mostly the hardware is the reason.In EU, there should be a chance to address a warenty issue with detailed report up to 2 years.Keep in mind, quality issues mainly effekts series, not single parts. So you need to verify all RAM modules, especially from same delivery lot (min 2, sometimes 4).

@davidrevoy I know another person that had some memory issues before. Linus Torvalds. He then stuck with ECC RAM."Torvalds shared a story from earlier in his career. He once used a system with non ECC RAM that ran fine for about two years. Then he started seeing strange segmentation faults and compile errors while working on the kernel. Naturally he assumed there was a software bug and spent days hunting it down. In the end the culprit was not a coding mistake at all. The machine itself had started producing bad memory data. With no ECC in place the system happily used that corrupted data until it crashed."Source: https://ejscomputers.com/blogs/news/linus-torvalds-perfect-pc-why-ecc-memory-matters-more-than-you-thinkandhttps://youtu.be/mfv0V1SxbNA?si=-vpyFLbrZZP-80lx

@davidrevoy you know, 4 modules, generally still a tricky thing even on newer platform, and switching to 3 modules switches you back to a single channel mode, I don't know if that's something you want, but depends on your needs. I know, now is not the right time to re-think you memory configuration, so, I guess make the best of what you have.

@herrorange Yes, I know that with this 3 modules, I'm loosing the Dual Channel, the manual of my motherboard is clear about it > "It is unable to activate Dual Channel Memory Technology with only one or three memory module installed"But for my painting application, getting more RAM storage, even slower sounds a better deal than just 16GB very quick. I really need this to avoid my computer swapping the 'undo operation' or 'clipboard content'.

@davidrevoy @alex Certains portables sont encore suffisamment “repair-friendly” pour qu’on puisse changer les barrettes de RAM soi-même sans avoir à envoyer le portable au SAV (pour combien de temps encore, ça reste à voir… 🙁 )Mais ça reste clairement plus pénible que sur une tour – avec beaucoup plus de trouille de casser quelque chose irrémédiablement pendant l’opération. Je l’ai fait une fois sur mon portable actuel (pas à cause d’une barrette défectueuse, juste pour avoir plus de RAM), j’ai pas vraiment envie de le refaire.

@lazy I can't imagine when it's mission critical, with life depending on this... Creepy random bitflip! Here I saw in my renderfarm the damage: it messed with the md5sum I use to triage if a file was updated or not in my cache, and launched re-render for many files; with behind it imagemagick, libPNG, zip, everything failing and they left corrupt files all around the place on my disk, then sync this with rsync to the server. I spent part of my Thursday into cleaning this up. Very destructive.

@davidrevoy I do remember having bad RAM in a pc we built out of bits on about 1998, we were playing Quake and would randomly fall through the floor where level data got loaded into bad memory
