They're referring to a different voltage setting than what's normally used by the CPU. Because of vdroop, the BIOS voltage will typically be higher than the actual CPU voltage. Your 5950X shows a slight drift above 1.35 volts when tracked with HWInfo, but it should remain stable as long as it doesn't stay there too long. Many users are used to manual overclocking where voltage is fixed, which can cause faster wear. If the system stays stable at a lower voltage, it's safe to proceed. Otherwise, it's better to keep it unchanged unless you're certain of stability.
I understand that current testing stability requires more performance than what most CPUs can provide.
Precision Boost and PBO serve distinct purposes. Ryzen achieves 100% boost when PBO is turned off. PBO tries to increase performance while maintaining parameter limits. https://www.gamersnexus.net/guides/3491-...ks-auto-oc
It's fine since it runs automatically, but it won't increase beyond its maximum speed, making it pretty ineffective.
Struggling to hit 4.3 on 1.35 or lower, prefer not to push higher. Something odd occurred: after setting 4.3 at 1.35, temperatures weren’t extreme, but lowering to 4.2 caused a sudden spike to 95°C. Eventually stopped testing due to errors. Maybe I should stick to around 4.1 and let PBO turbo reach its rated 4.2 when needed, avoiding the rounding issues on prime.
I’d reset the CPU to its default setting, then execute operations like prime 95 small FFTs to observe the board’s vcore output. Using that vcore, I could establish a stable static clock. Achieving around 4100MHz would be reasonable. My initial AM4 board was a 3600XT running at 4400MHz with 1.2875v and 4500MHz at 1.3375v.
Just adjust the multiplier and voltage. PBO doesn't work well with Zen2.
Decide whether to switch it off or keep it in auto mode. For your last point, monitor the stock, apply stress tests, and verify the hardware feed from the board. Then choose the setting—4.1 or 4.2—based on what you find.
