9800X3D PBO Testing

Hi

I’ve been dialing in PBO/CO on my 9800X3D coming from a 5900x and wanted to see if I’ve basically covered stability testing or if there’s anything else I should throw at it.

PBO / CO settings:

PBO: Enabled, Scalar = Auto, Boost Override = +200 MHz

PPT/TDC/EDC: Auto

Curve Optimizer (per core):

Core 0: −36

Core 1: −28

Core 2: −38

Core 3: −39

Core 4: −40

Core 5 (best core): −32

Core 6: −38

Core 7: −48

Stability tests completed:

CoreCycler + Prime95 SSE HeavyShort (~6h)

CoreCycler + y-cruncher 19-ZN2 (AVX2, ~6h)

CoreCycler + y-cruncher ZN5 (AVX512) 5h

OCCT stress test

Prime95 SSE All FFT overnight (~12h) ,

No errors/WHEA, temps are fine and system seems stable

Are these values normal for this chip? Did I luck out? or is there any other test people recommend for complete stability testing?

Thanks
