-cvddc -100 - Apparently you have to set it to relative values.
I use absolute value for all of my 5700XT cards and 6600. Is this special for 6600xt? The API help says "Set GPU core voltage in mV (0 for default)" and doesn't mention the relative value. May it works also.
In my case, 6600 non-xt, PM takes the absolute value. The log shows below. I have "-cvddc 900" in config.txt
set GPU clocks to 1100 MHz (Vddc 900 mV)What the log shows if you use absolute value for 6600xt?
Log says it can only do relative values.
ReleaseNotes.txt:
- Implemented optimized kernels for AMD RX6600XT cards
- Added support for the latest AMD Windows drivers (21.10.2, 21.10.1, 21.9.2, and 21.9.1).
- Added support for the latest AMD Linux drivers 21.30
- Implemented full hardware control for AMD RX6900/6800/6700 cards under Linux.
Note that with these cards under Linux you need to specify relative core voltage:
e.g. -cclock -50 will set the core voltage to be 50 mV under the default value
Apparently it also counts for -cvddc
Alright, you are using Linux and I am using Windows.
