I'm currently on 1002, and I plan on updating to 0079 bios with the new microcode. I have a question about p-states. I have a manually overclocked 1700x to 3.9 on 1.35v, I noticed that in the OS idle or not its essentially hovering around that voltage constantly. Are p-states just flat out disabled when manual overclocking is done? Also does enabling epu power saving mode on the board adjust the voltages based on usage? Or are we gonna just have to use the zenstates software to do this. I'd like to spare my cpu from being locked in at a set voltage when theres no load on the cpu.
I thank you in advance for your help and information (I would have tried the epu power saving etc, I'm just at work at the moment and my curiosity is killing me as I won't be able to get home and experiment until late tonight).
Whenever you manually overclock, and go above the factory set levels, the CPU enters OC mode. In OC mode, all power saving options are disabled.
I wouldn't mess with the EPU at all if you're overclocking. That would only be useful in a handful of ultra low power use cases.
Right now, I would recommend using one of the AGESA code BIOS' (0079 or later) and the new ZenStates 0.2.2 program elmor put out.
Just set your CPU voltage to auto, manually set your other voltages, and set global c states to enabled. Disable bank group swap, if you are using single RANK DIMMs.
If you're using the default Ryzen power profile that came in the latest chipset driver, you will need to change the minimum processor state down to 0% to get proper down clocking for the P1 and P2 states.
