BSOD randomly (mostly) when idle dxgkrnl.sys

VTT should be bumped to 1.168 V and the system tested by doing your normal routine in Windows for twice as long as it normally takes for a crash. See if the system runs stable.

Sounds good. I will implement that immediately.

Just out of curiosity though, if changing these values were in fact the fix, theoretically wouldn't running through Memtest86 again result in no errors? If so, wouldn't that be a quicker stability test? Don't misunderstand though. I'm not challenging your instructions. I'm really just genuinely curious. As much as this BSOD sucks, I am actually learning quite a bit through these various troubleshooting attempts.

Running Memtest86+ is another option if you have time to do so. Often, Windows is a better test of the RAM settings than Memtest86+ because it stresses the RAM in more ways than Memtest86+ does. Also, testing the RAM through Windows allows you to do your normal routine rather than being kept from using the system during a memory diagnostic.

If you have the time and patience to run Memtest86+, it would be a good idea to do so to see if the errors still occur.

Alright. I'll do that as an initial stress test. I most definitely have the time. My present computer needs are being met with an old iMac I have lying around. It's only my gaming that is suffering in the meantime

I'll relay the Memtest86 report once it's had several passes. If it comes up error free, than I will convert my daily computer usage back to the PC and stand by for a potential BSOD. Thanks.

You're welcome. Let us know how things go as you progress.

Wow! So, there have been 5 passes so far and no errors yet. The last time I ran Memtest86, the errors were early and often. Now, none. I'm not going to get too excited yet as it still has to go through a Windows stress test for a good month before it's wise to call it good. Nevertheless, it's a promising development.

Educate me. What does the VTT voltage do and how would increasing its value potentially be the fix for the problems I was experiencing? From what little research I managed to do, it has something to do with the CPU. Right?

The VTT voltage increase provides more support for the CPU's memory controller. The default VTT in many motherboard BIOS settings is designed for up to 4 GB of RAM. Usually 8 GB will run fine on these settings, as well. Anything over 8 GB in my experience will need a voltage bump for some systems. I'm hesitant to say your problem is solved, as well. Errors in Memtest86+ leave a bad feeling, but hopefully now that you are not getting errors, Windows will run stable and you can come back in a month or however long you need to feel comfortable.

I'll remain subscribed to the thread, so whenever you are ready, just post back, and I'll get a notification in my e-mail. :)

I really appreciate it. I cannot thank you enough for your patience and your continued support.

No problem. :) Best of luck!

...and again. This is frustrating.
