    Constant and Random WHEA_UNCORRECTABLE_ERROR


    Hi all,

    For the last week I have been trying to figure out why my computer keeps getting WHEA_UNCORRECTABLE_ERROR BSODs, with no success. They happen constantly and seemingly randomly, anywhere from 30 seconds to 30 minutes after turning on my PC. Hopefully one of you can help out.

    My PC specs:
    OS: Windows 10 Pro, Version 21H2 (OS Build 19044.1645)
    CPU: Intel Core i7-8700K 3.7 GHz 6-Core Processor
    MOBO: ASRock Z370 Extreme4 ATX LGA1151 Motherboard
    RAM: G.Skill Trident Z RGB 16 GB (2 x 8 GB) DDR4-3000 CL15 Memory
    SSD: Samsung 850 Evo 250 GB 2.5" Solid State Drive
    HDD: Western Digital Caviar Blue 1 TB 3.5" 7200RPM Internal Hard Drive
    GPU: EVGA GeForce GTX 1060 6GB 6 GB SSC GAMING Video Card
    PSU: EVGA G3 650 W 80+ Gold Certified Fully Modular ATX Power Supply

    I've tried the following to test various things:

    Drivers:
    Reinstalled MOBO-suggested Drivers (from ASRock > Z370 Extreme4)

    CPU:
    Intel Processor Diagnostic Tool: No errors
    Prime95 Stress Test
    Idles around 35, 55-60 in the stress test
    Cleaned and reapplied thermal paste

    GPU:
    Removed GPU and uninstalled drivers

    HDD/SSD:
    Attached one at a time, tried to reinstall Windows on both
    Detached both, tried to install fresh Windows from USB to new SSD
    I get WHEA BSOD during both the above.

    RAM:
    Windows Memory Diagnostic: No errors
    Memtest86+: Found a pair with errors, RMA asked to return the pair of sticks (1 good and 1 bad) together. Other pair is okay. 10 passes with no errors.

    PSU:
    Jumper Test: Works
    Watched rail voltage: 3, 5 ,12V rails all had appropriate voltage without spikes

    Motherboard:
    Reset BIOS settings (by just loading default in BIOS)
    Clear CMOS Jumper
    Reflash BIOS

    Windows:
    Windows Update
    sfc /scannow
    Dism /Online /Cleanup-Image /RestoreHealth
    Tried to reinstall through "Reset my PC" as well as downloading a fresh copy to bootable USB and trying to install to a brand new SSD, but I get BSOD during the process.

    I've also tried taking a look at the dump files using WinDbg, but couldn't find anything. I'm guessing it could just be an actual CPU/PSU/motherboard hardware issue, but hopefully I can narrow it down and not have to try replacing parts one at a time. Also, my PC does not seem to crash when booted into Safe mode, if that helps narrow things down.

    Logs from the V2 Log collector are below:

    Hi,

    Did your computer crash with these RAM modules that tested negative for errors in the brief period of the Windows install?

    I am asking, because I see the same pattern of crashes in your logs indicative of RAM problems or possibly the memory controller which would point to the CPU.

    Yeah, even when using the RAM with no errors, I would get a WHEA crash during a fresh Windows install. Are there any other RAM/CPU tests I can run to keep checking?

    Probably, but I can already tell you that they are no complete tests. No software test can 100% test a hardware component because it is simply too complex.

    Your best option is to swap the component.
