Oh.... Some of us find it very handy to use a few things in steps along the way. Prime95 for me is the last of the tests after getting by the first clocking steps where there are sure to be adjustments needed. To make a tweak and run Prime95 for several hours and then tweak again to wait another several hours..... every time I make an adjustment..... is painful.
May I suggest:
Familiarize yourself with Windows Event viewer in, Settings/Control panel/Administrative Tools/Event Viewer. Go there and select the top of the list "Event Viewer (Local) so it will show you a window similar to the screen shot below. Then expand the categories especially the Critical, Errors, and Warnings and see what you have. Now don't freak out on every issue, because there will be non-critical stuff there, just key in on WHEA's. If you have none have a beer and celebrate. But with those temps and that DVID, I dunno. I am a novice just trying to share.
What my mentor pointed out to me is if we have WHEA warnings in the list we still have tweaking to do before we can claim to have a stable build. My guess is you have them.
Do your first BIOS clocking and run Intel Burn Test on high and see if it passes. It does not run as long as Prime95 but if you have major or obvious corrections needed you will get a failure message. You can then make adjustments and run it again, all the while going back to Event Viewer in between to see if WHEA's are still being generated.
I always have a RealTemps window running and CPUID so I can monitor things.
After I get Intel Burn Test to run with success and no or very few WHEA's, I then run Prime95.
