So I have a rig running (4) XFX R9 290s for about 3.5mh/s. I was just wondering what are the optimal cgminer settings for these 290s. Right now they are all running around 83-84 degrees, is this too hot or are they suppose to run this hot?
My settings are:
GPU: 1000
Mem: 1350
Intensity: 20
fan speed ~75%. (auto)
You can up the fan speed to 85%, but don't go above that.
Are you are getting 875kh/s with each (that's pretty good)? What's your WU like?
And for your question, 83-84 is ok-ish, under 80 is good. Did you undervolt?
