@eXe_NIBIRU, that crash is the one where the CPU decides to execute an instruction starting in the middle instead of at the beginning (like one that @Lunchb0x88 just reported). A properly functioning CPU shouldn't be able to do that.
I'm not convinced that this problem is limited to overclocking, but it might be an exacerbating factor.
Overclocking can cause faults even without overheating. If you're overclocking, you're reducing the time the CPU is allowed to take for each step of each instruction, but the transistors still toggle at the same speed as they execute each stage. If the clock is ever shorter than a step of an instruction, the next step of the instruction can start before the previous step's results are done.
As an analogy, imagine you're doing a 10-digit addition problem, and somebody else is going to use your answer. Normally, they give you enough time, and you get all 10 digits before they look at it. However, if they're in a hurry (as in overclocked), they may look at your answer when you've only written down the first 8 digits. They don't see the problem you're working on, only your answer, so they use those 8 digits as if it was the correct answer, when it's not - it's just part of the answer. So anything they do with that number is likely to be wrong.
Overclocking and overheating can both cause rare CPU errors. You can get errors from overheating without overclocking, and you can get errors from overclocking without overheating. If you're both overclocking AND overheating, that's really pressing your luck!
Again, I don't know whether this is due to overclocking or not, but I do know that none of these crash reports seem possible with a properly functioning CPU.
I absolutely need everyone who is crashing at stock CPU speeds to disable Spectre and Meltdown protection as per my above post last page, and see if that helps stability.
If there is a bug in the Intel microcode, Intel needs to hear about it. (This is only for current updated versions of windows). I'm still seeing people post crash reports and 0 people attempting to do what I suggested just in case. As I said, Intel pulled older Kaby/Coffee series microcodes before because they were actually destroying chips...(9900k and 9700K were not released yet).
