Just want to share my experience about problems due to bad default configuration on many systems with chipset x299 and Skylkae-x cpu. So it seems to be a flaw from Intel or all motherboard manufacturers. I hope thhey can fix this cause it has made me loose a lot of time. I hope my post can help others avoid loosing so much time.
I have a x299 and Skylake-x cpu (i9-7980XE on Alienware Area 51 R4). And I had A LOT of blue screen (6 or 7 a day). But the solution is not to disable Intel Turbo boost like some people think. If you disable it your cpu will work less and will just have less chances for BSOD. If you don't use the cpu at full load, you will not get BSOD but we all want to use the cpu at full power or why do we pay that much to Intel?
I found the solution on Puget System website: https://www.pugetsystems.com/labs/support-hardware/WHEA-UNCORRECTABLE-ERROR-on-Gigabyte-x299-and-Skylake-X-SOLVED-1042/
And it works!!! No more BSOD for me and I even overclock my cpu (an i9-7980XE on Alienware Area 51 R4)
So I just increased my cpu voltage to 1200 (the default was 0) and I let the mode to adaptive (the default anyway). And from that point the BSOD stopped! So it's like the cpu are not having enough voltage for the turbo by default. So you need to give them more voltage or they simply don't work!
Then I wanted more juice so I tried to overclock the cpu and the BSODs were back. So I then lowered a bit my overclock and jalso put 5 in each of AVX offsets (there are 2 in my bios). And then it seems I no blue screen anymore even on overclock.
My BOSDs were happening when rendering with V-Ray in 3ds max.
Many people have this problem so it's really a flaw with Intel cpu so I hope they can correct this, I lost so much time trying to troublweshoot this: I changed my motherboard, changed my ram, reinstalled windows all possible ways, I spent days and days and days on this! For a cpu that I paid almost 3000$ that's quite disappointing to loose so much time...
Here are some links of other people having the same problem (but the best solution is from Puget Systems website (last link or see same link above):
I hope Intel will test their cpu a bit more before releasing them with such obvious flaws or is it that they motherboard manufacturer are not aware of how to setup the bios by default for those cpu.
