Re: CGminer + Radeon HD 7850: Hardware errors [0.002 BTC award for solving]
...
Therefore, along with a 7900 series card as a display card, with 8GB of memory on the desktop, I was able to tune the 7850 with the following settings to get over 360khs on this desktop, and another 7850 (by itself) to run at 380khs, all without hardware errors:
--intensity 12 --gpu-threads 2 --gpu-engine 1050 --gpu-memclock 1200 --gpu-vddc 1.1500 --shaders 1024 --thread-concurrency 4096 --worksize 256 (dont just copy paste in case i mis-spelled something)...

Thank you for this! I was getting either errors, or very low hash rates. I tried a lot of different values but I didn't think to try 2 gpu threads! I just pasted the above settings right into cgminer (as you advised) and I'm now getting a constant 360k with no errors (yet)!
I will definitely toy with it more, but I'm just happy to have it running.
