    Hi Archeon,
    Just when I thought we had found the cause of the BSOD's. I have been running the 2 mem modules in slot 1 on both banks and leaving slot 0 on both banks empty. I have used the PC extensively - no problem. The PC has been on non stop since then. I got up this morning and found that the PC had rebooted during the night. This is when it was idling. Attached please find the mini dump. Just wanted to check if memory is still the problem as there may have been a power dip or something similar during the night causing the reboot.
    Kind Regards,
    ZuluShark

    Same issue, i.e. memory corruption with PFN List errors at addresses 82fbc0c0, 82f6a0c0, and 82fa20c0 respectively.

    By the way have you installed/updated motherboard/chipset drivers for this board ?

    Is this RAM is under warranty?

    Hi,

    Yes the Modules have a lifetime warranty.
    I have not downloaded any updates/drivers for the mobo or chipsets.
    I will create a restore point and then d/l any available updates and install.

    Ok, I am totally guessing here, because we have so many other avenues, perhaps the modules are not compatible or something like that with your motherboard?

    Edit:
    One more thing, is the RAM Voltage in BIOS is set to 1.5V ?

    Checked the BIOS voltage for the Mem Modules. It was setto Auto. I have changed it to manual and set it at 1.55V (the closest to 1.5V of the options available)

    sounds like i was having the exact same problems but setting at 1.500 didn't help me.

    I hope it is Zulu, if you need further assistance just let us know.

    @00firebird
    It is always best to start your own thread, so you can get specific help for your own issue.

    Anyway, what are the exact specs of your system including PSU, OS etc.

    Hi Archeon,

    Just to say thank you once again. Setting the Voltage for the RAM to 1.55V has done the job !!!!

    You are welcome, I'm glad it worked out to be a perfect solution Zulu, safe/happy computing.

    @fire
    You may need to fiddle around a bit with settings/voltage to see whether your system stabilizes.
