how do you guys get R9 290x working with cgminer?

whenever or whtaever I try i get the decrease TC increase LG error.

only way for me to mine with 290x is using Guiminer-scrypt

I solved this problem by adding another 4GB memory stick to my rig to up the memory to 8GB.

To repeat, to get the Thread Concurrency above 8192 or 28160 which is 10x 2816 shaders it seems that the pc needs more memory. I have no idea why.

Also, I read on here that TC should be at ~ 12x shaders, or 33792 was good, but i got better performance at 32765. 875 stable Khash/sec.

Also, I am working to see if adding or removing --auto-fan helps hash rate. does anyone know about this?

EDIT: I just tried with and without the --auto-fan option, and no effect on hash rate.
