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
