Question 5.0ghz 9900k oc crashes on r15 but runs stable on everyting else

[KFCCCCCCC]

why is this happening? I'm running a 5.0ghz on my 9900k on a aorus z390 pro motherboard and when i run prime 95, aida64 and cinebench r20 it all runs stable but when i try running r15 is crashes.

Verify the AVX2 offset.

If it's crashing it's not stable...you'll have to tweak voltages or reduce clocks...Cinebench R15 doesn't use AVX so that's not likely the issue
