Double-check you enumerate your GPUs correctly. I know it sounds like a silly suggestion, but you know... been there, done that.
If the onboard GPU is anything AMD, it gets listed too (usually GPU0).
I hear ya, made plenty of stupid mistakes myself. But yeah, TRM miner shows the bus number and changes I make to the other GPUs do take effect. I’m wondering if it’s because I’m using CLI and the - -i parameter and it’s not reading the last GPU in the parameter setting?
You don't happen to start TRM with a -d in config?
No, but I’m going to do some further tests tomorrow with the latest version and see what happens, maybe double check the settings with the GUI (I’m using CLI right now).
You're using '--i' and not '-i', correct? The example usage in the help text (amdmemtweak --help) shows the latter, which is not valid. (EDIT: this was the case in older versions - appears to be fixed in the latest)
