First and foremost stop tying to compare the way X68/Z77 BIOS works with X79, there is no profit in that they are not the same. There might be some cosmetic similarities but that is coincidental. However your 'bugs' are noted and will be replicated by me to confirm.
🙂 So thanks for that.
Second - when you system gives you these BSOD are you at defaults, and that includes memory? And out of interest is your OS a fresh install or the old Sandy OS that you have just put into the new system?
Here is what I would do. Download the bios again. Use a fat formatted USB device and the flashback method I would re-flash the bios. Let your system do the full firmware upgrade if required.
Then I would clear cmos once the entire process has completed. That done into BIOS and set your SATA mode if running RAID. Now boot to OS and see if your system is stable, play your favourite game for a couple of hours, not overly worried about stress tests as they prove nothing to me.
Here is what I would do. Start with the memory. Use the XMP profile as your starting base, you can either set the profile values manually or let the system do it for you. I like the manual method but both work just fine. Ideally I would suggest your follow the guide to memtest86+ in my sig to the letter that will take out a whole heap of the variations that might be the cause for your issue.
With your cooler you are not going to get too much OC done with that CPU. But here is a good instance where a stress test has value. See how your Cooler copes after 30 minutes of Prime or similar. If still manageable then all good.
0124 is 99% of the time vCore.
Will check back later.
