I am using the following hardware:
I-7 7700k
ASUS Prime Z270A motherboard
EVGA 1080TI
EVGA 2060
32MB ram

This is my app_config.xml

</app_config>


Is there anything I need to change to get better results?

You have paired a high end GPU with 11 GB of Memory with a Mid-range GPU with 6 GB of Memory. You also have your sbs set tp 2048, which would be fine for the 1080Ti when running 2 work units per card but with the 2060, any work unit would be starved for Memory after the first work unit loaded.

So you can either removed the 2060 (which I don't think you need to do), Change your setting for 1 work unit per GPU (also not necessary) or change your values for sbs to 1024 to free up some RAM for the second work on that 2060.

Truthfully, the best ratio for a 1080ti is 3 SoG per GPU but that's not going to work with a 2060. There is also a lot more commands in your commandline than I ever used with the SoG.

Might want to read thru this thread.

I am only seeing 56 to 57% of memory being used on the 2060 card.
