“Error setting OC mode”

[fyr233]

Hi, I'm new to ZenStates. I just build ZenStates dev branch with ZenStates-Core.
This is my CPU info:

When I enable Manual Overclock and click Apply button,

The out status here is 0xFD,

and cause an error.

Is thie behavior expected? What should I do?

Hi,
Milan is pretty much unsupported, the limited support in the app is done mostly based on assumptions.
I don't have access to server hardware, but the last Epyc that could be somewhat overclocked was Rome ES/EQ.
There are some possible reasons for the error:
a) SMU command ID for setting manual OC mode is wrong
b) the chip has manual OC disabled on firmware/fuse level
c) the motherboard's BIOS is configured to disable the command

There's a way to possibly find the correct command ID (if supported at all), but this involves blindly trying different IDs which might lead to unexpected behaviour and some people even killed Rome ES chips by doing that.
