Re: My Scrypt Miner, Best Settings for 7850?

I had my 7850s running with --gpu-engine 1050 --gpu-memclock 1450

That would get me ~380 kh/s each

Not sure about actual watt consumption since I didn't have a kill-a-watt

Can you elaborate please? What exactly do those commands accomplish? The memclock command overclocks the GPU right? How about the gpu-engine command? What did you have for intensity? Also, any thoughts on the --thread-concurrency command?

Does anyone have a good resource for learning the cgminer settings?

Thanks!

The memclock controls the speed of the memory on the card. The engine controls the core speed. 

I usually run all of my cards at I 19, but I'd play around with that and see what works for you .

Concurrency should be 64*memory bus width => so 64 * 256 = 16192 (I typically run 16000)
