7500f/7600 undervolt equalizer set to PBO -30
This feature of the PBO Curve Optimizer sets it apart from standard voltage offset undervolt solutions. The level of offset changes along the voltage range—lower at smaller voltages (around 90mV) but higher at larger voltages (up to 150mV). This means there isn't a one-size-fits-all approach like in traditional undervolt methods.
Needs to verify SOC voltage again. Previously lowering it caused system crashes if I recall. Right now, 0.08 v with auto SOC gives slightly better temps—89°C and 84 watts versus the original 90W and 91°C. This suggests a similar result, but further reductions bring scores down by about 300 to 400 while also dropping temperatures significantly into the low 70s.
I reached as low as 1.05V without any problems on my direct-die 7950x3D. Every other setup I've used set it to 1.15V and stayed stable, which is roughly a 100mV drop. This has covered about five different AM5 models so far, with a couple still untested. Keep in mind this applies to systems using dGPUs and 6000MT/sec EXPO/XMP RAM packages. The iGPU could struggle at full load when heavily undervolted via IOD, though that's just speculation.
Identical with any stable low voltage, reduced energy use while maintaining the same output.
