Update:

A while back, I attempted to swap out my ram to see if the random code 29 was caused by that, and it still occurred.
About a week ago I got a new 9820x cpu and installed it, only to see...

I’ve already tried flashing the latest BIOS again, both original and latest microcode modded. I’ve started a topic on Intel’s forums here and thus far all responses are that it is an ASUS BIOS issue...

I just bought a 9820x and I noticed that the BIOS shows the microcode is 00000000.
I previously had a 7900x and the microcode was shown correctly.
When Windows is booted, the correct microcode can...

I’ve had an issue with booting any 32-bit media with CSM enabled and boot mode set to Legacy Only since updating to 1301.
Issue persists with secure boot disabled and boot set to Other OS. Issue...

Timing changes seem to have no effect. I have tried running at their rated timings of 19-23-23-45-2T @ 1.35v with a lower frequency, but code 29 still occurs randomly. The only thing that seems to...

I’ve tried vDIMM @ 1.35v before without success, but not all three voltages increased at the same time. I’ve also tried setting vDIMM to 1.4v and eventual vDIMM to 1.29v, also without success.
