I have been tinkering around with PBO and curve settings, but will PBO go above 5250MHz on a Ryzen 9 5950x? In HardwareInfo 5250MHz is shown as the global max

Limiter is set to 200 (max) with limiter set to disable I only went to 5200MHz

+200 MHz is the clock offset limit for ryzen. not like it's stable anyways.

Play a game like COD or Forza and it'll probably crash. Or you are a God at overclocking.

run core cycler with either p95 AVX2 or y-cruncher for 12 hours and come back with the results.

Yes, PBO can go above the defined limit of AMD.

It's by using BCLK. If you increase the BCLK from 100Mhz to 102Mhz your looking 5355Mhz or so. Some boards go up a few more Mhz higher and some don't.

Golden rule is always cooling, and perhaps a tad undervolt, to provide a little bit more room for higher clocks.

But, bclk is extremely tricky. Some NVME drives do not boot beyond 103Mhz.

Well I did play 4 ours of Destiney 2 yesterday with these settings - but the points is its not a fixed OC its PBO boost and reflects the cooling

Will try that @Jism and the changeing my TDC and EDC on a higher setting when I get a cold day

I cant get my all core boost in GPUz above 4500MHz during the test with my current settings so its not cold enough to beat my personal best yet :)
