FYI, I completed an evaluation between win10 driver 18.6.1 vs 19.4.2. Found no hashrate/power draw difference with TRM 0.4.4 miner. Evaluated on CNR algo only.

Still using ODNT? How do you set your fan speeds? IIRC there is no target temp in the beta version.

I tested a few 19.x drivers recently, on a 3x vega 56 rig, TRM 0.4.2 (also CNR only) and came to the same conclusion. Didn't have enough time to play with ODNT, but it felt weird having to spend time tweaking fan speeds. Target temp has been a set and forget kind of thing for me so...

You can set your target temp in PPT...

Vega (hex short, byteswapped -- e.g. "1c,00" => 0x001c => 0d28):

Polaris (hex char -- e.g. "28" => 0x28 => 0d40):

Thank you for that!! It seems to be working! Your posts have always been immensely helpful.

I can't try the beta ODNT right now as I'm currently on old drivers and it's crashing so, am I right to assume the fan speed section can still be disabled in beta?

Np - happy to help. I don't know about disabling, but ODNT just reads the value from PPT, so you shouldnt need to worry about it, unless you want to change it.

It doesn't seem to be reading it from PPT, I just double checked to make sure. Apparently it just defaults to 75 no matter what value I set in PPT. So unless the fan section can still be disabled in newer ODNT versions, it will just override whatever is set in PPT apparently.

Sorry - was thinking more of older versions. Don’t have much exp w/ windows since 19.2. Based on what @kerney666 said, it sounds to me like fan support is actually broken in later drivers. Like you, I’ve always found target temp to work perfectly in the past, but wattman still provided working fan curve support for those inclined.

Seems like the new fan curve impl has borked a number of things.
