I have terrible case cooling -- don't ask.

I'm unable to get 950+ at any settings.

Only relevant parts quoted - nuff said... fix your cooling situation - VRM and GPU needs to stay cool.

stop using gpu-threads 2... 1 is optimal for 290(X)

Where the heck is that thread-concurrency from? Try some normal numbers as posted everywhere.

If you are tuning intensity/xintensity, get rid of the shaders line.

Crank your FAN! Why are you using variable? Stick it to 90 or 100% if you need to to keep it cooler. temp-* is too low. cutoff should be 95, overheat something like 97, and target 92.

If you are mining on a pool that has a good reject policy, crank the xintensity up - 1100 is a good value. Only pool like CM, or solo-mining low-diff coins, will reward a low intensity.

Thanks for the reply.

The TC is from 2816 * 8 + 1 and just a guess. Where the heck is 24000 24550 32765 from?

2816 * 5 + 1 = 14081
2816 * 6 + 1 = 16897
2816 * 7 + 1 = 19713
2816 * 8 + 1 = 22529
2816 * 9 + 1 = 25345
2816 * 10 + 1 = 28161
2816 * 11 + 1 = 30977
2816 * 12 + 1 = 33793

It doesn't seem happy using more than 30k thread concurrency so I'm using *8 at the moment. I can remove the shaders line but I am pretty sure the card has 2816 shaders so I doubt it makes a difference. I'm willing to entertain other numbers but I'd like to hear a reason.

I want to keep the fan low (hence 60-85) and the temps low to increase overall longevity of the card and avoid a bad time when summer hits. I'm willing to give up some kh/s to do it but I also want to run an optimal setting. Giving up 10% so far seems like an OK deal but 5% would be nice. I'll try a single gpu thread and see where that gets me. And more trial and error. I think it was generally better than 2 in my attempts earlier.
