Hi

I run a 13900k with an Asus z690 Prime-A, DDR 5 ram 2 x 32gb (no XMP). 360mm AIO. RTX 3080Ti.

I built this system in December last year. Everything has been running fine until start of this month (November).

It started with the software I use for work crashing every 5 minutes. Error code being 0xc0000005. I contacted developer and they created 3 debug builds to pin poin the error. The latest crash dump confirmed our suspicion, “It might be a CPU bug”.

Today, I saw another post saying ASUS board are causing high core density CPU’s to crash?

Any testing software that can pin point which part is causing this? All tests are coming back negetive for errors.

From the developer

Now it is obvious it is not a problem in the Editor.
Here is the problematic instruction sequence:

00007FFFCE548A6D  mov         qword ptr [rsi],6Fh
The rsi regirter changes its value somewhere in the middle, because the first and the last instructions write to different memory addresses (the last one was captured by the hardware data breakpoint and generated this crash dump, while the first one was executed normally. And there no instructions in between that can change the rsi register.

    Very much looks to me like a software bug. It would be helpful if the developer also posted register dump of RSI and the memory location pointed to by RSI.

      PDF Xchange crashes often .

      Microsoft word crashed

      Discord crashed Steam crashed

      I don’t know man, it feels so unstable for work…

    it might be your cooler is too tightened and causing bending. i’ve honestly never heard of the asus board issue.

    So… I just went through hardware replacement after replacement chasing this

    I was 13900k on Asus Prime z790

    Ram NVME PSU Motherboard

    All were replaced in that order w/same

    Then Intel stepped in and replaced the processor.

    It was the processor. Start your RMA with Intel.

    I had a problem also this year with a 212 Evo and z170 7600k cpu couldn’t figure out what was the problem, literally spend a year trying to solve the issue, the issue was the coolermaster 212, somehow it manage to bend the mobo, probably cause bad contacts somewhere XD, my most painful experience.
