A TC as high as 58624 won't work on any of my cards.  Right now, I primarily use either 20479 or 28672 , although different values seem to be optimal for different algorithms/clockrates/BIOS versions.  My experience suggests that lower thread concurrency actually yields better results a good portion of the time, and I find the lowest (shaders*n)+1 or -1 value that doesn't produces HW errors often yields the most completed work.

I will pull and build YACMiner on one of my rigs setup later and see what happens when I try your posted settings.

2> STFU

I am not looking for a troll war.
