  • Need help interpreting memtest results!

    Hi, I have a 1 day old full rig that I built myself with a i9-9900k and 2x8GB DDR4 3200MHz (PC4-25600) CL16, XMP 2.0, which gave me BSOD after 1min of playtime in PUBG giving me the famed "page_fault_in_nonpaged_area" BSOD after a mere minute of playtime. Important to note: XMP Profile was not enabled.

    I then disabled the "automatically manage paing file size for all drives" in windows - which seemed to help for a bit, but more problems would arise, crashes in other games, system had trouble downloading and reading game files over and over. I then ran a chkdisk - everything fine - now at this point PUBG and CSGO were running fine besides some stutters I'm not sure whether to attribute to my poor internet connection or my system. My now main issue was on another game that I tried(Escape from Tarkov), the game would launch, but when loading into the map/game it would simply crash/close. Multiple resets to no avail. I then tested my RAM sticks 1 by 1, still crashing. Was originally using A2 & B2 slots, after I was done troubleshooting RAMs I switched to A1/B1 - still crashed. Then I ran MemTest86, and got some results I have no idea what mean:

    After this I thought of enabling XMP profile in UEFI - things seem stable enough now- have been using my system and gaming hard for 10hours with no crashes/bsods or any other major faults, maybe some stutters but nothing major - however the results from the memtest were quite jarring as it looks to me as it's more of a CPU problem(?), and seeing as my system is brand new I can easily return defect hardware and get a replacement. What is your advice? Thanks in advance!

    I then disabled the "automatically manage paing file size for all drives"

    It is an Internet myth that this helps fix anything. Worse; most people who change the setting have no clue as to the real effect.
    Don't do it.

    From the log above, it looks like the RAM is bad. See,

    Turning on XMP won't normally help, but maybe the XMP profile slightly lifted the voltage and fixed (hid) the bad RAM.

      Yes I figured this was just a load of malarkey after a while, I turned it back on before I started troubleshooting ramsticks.

      Okay, well that's a relief, sorta, I've ordered some new RAM now, different brand but same size/speed so let's see if that does the trick!

      I'll be back with the results as soon as the new RAM arrives.
