I'm hoping my advice will help, but your issue could be something completely different.

I have an x299 board from ASUS and I was having the exact same crashes. I finally figured it out and solved it after a few weeks of tinkering.

It turned out that the stock voltage used in the standard (non-overclocked) motherboard profile wasn't giving the CPU enough voltage.. I have a 7940x. This meant that the machine ran fine, until it was put under any sort of load and then it would crash, especially in stop start workload environments.

Try and run CPU-Z on your processor and let us know how much voltage is being applied to it. This might identify if it has enough juice. From memory I went into my BIOS and changed a few power delivery settings so that when the CPU needed extra juice the motherboard would gladly give it to it.

If you're unfamiliar with BIOS settings I can try and point you in the right direction, but the thing that worked from me was changing the regular "Auto" AI-Tuner settings into "Manual" and just trying things until the system felt a lot more dialed in. From memory, I applied 1.08v to my CPU and that seemed to stop the BSOD's completely.

It was the first time I had in my computing history where my overclock was more stable than the factory settings.

I wouldn't recommend overclocking if you aren't familiar with what to do, but Linus has some good tips on ramping up power delivery on ASUS boards to i9 chips in this video:

Good luck!

Hey, thanks for chiming in. I have the same MB and same CPU.
And yes, somehow my feeling comes from it having to do with power voltages.

I managed to install the Windows Debugger and went deep into the memory dump and all I could find is that "GenuineIntel" has to do with it, so the CPU.

And yes, opening the CPU-Z window, I can see that my voltage is usually at around 1.05 and ofter way lower (its jumping a lot between 0.720 -1.110 frequently) . Hardly ever going up. And from reading into forums the 7940x should have a hower cpu voltage. (Although I could be mistaken here).

Also every time the crashes happened it didnt feel like it was stressing anything particular really hard, it happened instantly. For example just changing a port in the node editor in octane c4d while the two cards were rendering inside the IPR in the background.

So yeah, your solution does feel like it could be it. I definitely have to try it out, but like you said I'm a total newb in overclocking. Could you tell me exactly where you changed this? Since we have the same BIOS.

So my motherboard is an Asus Rampage VI Extreme, so I think we actually have different motherboards. However, it is the same manufacturer and same chipset so all of this should largely apply.

The aim of the following settings are to get your CPU to work at stock settings. There's nothing really crazy going on here, but be careful if you enter a wrong number you can definitely damage some expensive hardware!

These were the settings I got to work with my hardware. Bear in mind that your settings could need to be different.

AI Overclock tuner - MANUAL
Asus Multicore - AUTO
CPU Core Ratio - AUTO
CPU SVID - DISABLED
CPU Core Voltage - MANUAL
CPU Core Voltage Override - 1.090 - (Make SURE this value is no higher than 1.100. The temperatures otherwise might ruin your CPU. The lower the voltage the lower the CPU temp. I think 1.080 also worked for me before I eventually overclocked my CPU).
CPU Input Voltage - 1.540 (this is kind of the high side, but I needed it to work with my CPU)

Extreme Tweaker\Digi+ Power Control Section -
Load Line Calibration - LEVEL 2
CPU Current Capability - 140%
VRM Spread Spectrum - DISABLED

(Can't remember the name of where this setting is - but it has something to do with the CPU)
Intel Speedstep - DISABLED

Also, might be a good idea to install CoreTemp and check that immediately once the computer has started up that your temperatures aren't going crazy. If your temps start going higher than 70 degrees with no load then something is wrong.

I hope these settings help you instead of blow anything up. But perform at your own risk!! (as necessary as it may be to do). Without being in front of the machine it's hard to gauge what exactly needs to happen. These is just my experience - Good luck!
