    Memtest86 fails at 10k errors, but the system seems stable. Am I missing something?

    Recently changed my boot drive and reinstalled windows. Didn't touch CPU/RAM hardware or settings during the process. System had been VERY stable before the drive change. After Windows was reinstalled I had a few BSOD crashes while getting everything installed and configured, that SEEMED to be related to GPU drivers, but I figured I'd run a RAM test to be sure. I hadn't run one in a few years on this hardware so I figured why not.

    Loaded up memtest86, ran it, and it started throwing hundreds of errors pretty much immediately. Within 30 minutes or so it hit the 10k limit and gave up. Didn't even finish the first pass. But the system seems pretty stable. I've been actively using it (although probably not really maxing out the 32gb RAM) for the past few days with zero crashes.

    In my experience even a couple of errors over multiple hours of testing usually means "bad RAM", so I would expect that many errors to mean something is really wrong. But that isn't matching the current experience so I am second guessing my assumptions.

    Am I perhaps doing something wrong with the Memtest settings? Or is my understanding on how stable a system can be with those kinds of issues incorrect? Any other advice? Thanks in advance.

    Hmmm. Stable except when it crashes.

    Errors seem to be limited to a fairly small range of addresses.

    Might just be getting lucky in Windows and those addresses aren't used for anything critical most of the time. I am guessing you are probably only using 20% of your RAM for critical stuff. Errors in video buffers, disk caches, unused RAM aren't going to result in a crash.

      The key is "had". There were zero crashes before reinstalling windows, and none after deleting and reinstalling the GPU drivers 5-6 days ago. I haven't run anything intense since reinstalling windows, but before that I pretty regularly ran plenty of modern video games. Not something that will usually take up a full 32GB of RAM, but not nothing. I think I've had maybe 1 BSOD crash in the 2 years prior.

      However, if this test is telling the truth, then it is what it is.

      I still don't know why my old M.2 drive randomly died. I know it happens, but it's pretty uncommon for that model ( <4 year old Samsung 980 Evo Pro). I'm wondering if maybe I had a power surge or something. If that was the case, something could have perhaps damaged the RAM at the same time.

      Anyway, I appreciate the confirmation. Really wish this had happened like a year ago with RAM prices and all, but oh well.

        There is also the adage, Don't fix it if it isn't broken. So you could just live with it if it isn't causing a problem.

        But GSkill offers a lifetime warranty, So the cost of replacement might be zero (or pretty low).

          Wow. Thanks. In all of my years building PCs, I never caught that.
