    Failing Prime95 on RAM test - HW failure?


    Hi all,Over this weekend I've been testing my RAM modules due to a request I got from technical support.
    I use Private Internet Access VPN and if I leave my VPN running for 24 hours, at some point its process will get killed.
    The support told me that I probably have a memory leak due to log files warnings, and I was asked to test my RAM.

    I own 4x4GB Corsair Vengeance 1600MHz on XMP profile over Z97 chipset. I used latest Memtest86 build and I tested each RAM module individually on each DIMM slot.
    Each RAM module was tested to 10 passes, which I believe is enough to establish an issue.No errors were presented.
    Yet. memtest86 is not enough because I don't really stress the RAM controller in dual channel mode.So I installed all RAM modules back in place, ran Win10 and disabled all 3rd party processes that boot with windows.

    I also killed every process which is not required.I launched latest Prime95 build and did a Custom test and allocated 14500MB (no FFT) and have only fixed 1024MB of virtual memory (manually handled, that is, not handled by Windows).

    I started the test on Aug 27, 08:57AM
    Worker #6 stopped working on Aug 28, 6:05AM with the following message:
    Cannot initialize FFT code, errorcode=1005 Unable to allocate memory.
    One possible cause is the operating system's swap area is too small.
    Torture test completed 276 tests in 21 hours, 7 minutes - 0 errors, 0 warnings.Worker stopped.

    All other workres are still running.Is this a HW issue? Configuration issue? or some OS corruption?

    :)
     

  2. [Win10 BSOD]WHEA Uncorrectable Error appears in a periodical manner

    Ok I Prime95-ed the PC and the crash do happens lots faster, it crashes 5 hours after the last crash. But the problem is is that a CPU issue or is that a RAM issue? Sense Prime95 uses both when testing. Also if the DMP
    refers to genuine Intel, it can also be a north bridge caused problem...?

    Bug Check 0x109: CRITICAL_STRUCTURE_CORRUPTION, A critical MSR modification

    Sorry I took awhile to get back to you.

    So I ran the memtest86+, again, but that time the 11th test returned errors.

    Tried all 4 slots, changed nothing.

    Tried other RAM sticks, also failed on that test.

    Bought 2 new sticks as placeholders, brand new straight from the store bought today... They failed too :/

    So now I'm thinking it's the motherboard, or the memtest is broken.

    So yeah... What are my options on testing the motherboard and maybe CPU? I know Intel processors have a special program, but what about AMD?

    I'm going to put the memtest on an usb stick and test again on this machine. And then I'll check all the "failing" RAM sticks on another machine, another motherboard, to see if it's the MoBo or CPU.

    Edit-

    The windows build-in memory test never fails though

    I'm now running prime95, to check on the CPU and RAM again.

    I'm also checking the old RAM sticks on a different machine

  4. Failing Prime95 on RAM test - HW failure?

    One thing that could be done is trying SiSoft Sandra. There is a free version you can download. This will stress all the major compnents in your system. CPU, RAM, GPU, etc. Run this and see if it fails on any specific test.

    Other things that could be tried to see if this is an OS issue are:

    Open a admin command prompt and type: sfc /scannow

    This will tell you if there are system files that are corrupted and will fix them in most cases.

    Could also try typing in that same command prompt: dism /online /cleanup-image /restorehealth

    This will fix the windows component stores if they are corrupted.

    I'll try the sisoft Sandra. SFC command didn't find any issues so I didn't proceed with DISM command.
