Hi,

Just started mining and on my main rig I am running a Radeon 7850 2GB card overclocked to 1100MHz Core and 5600MHz Memory but only hitting 230Mh/s - the second machine is running a GTX 550 ti at stock and only hitting 40Mh/s.

Anyone know if there is a guide somewhere to improve performance for windows mining?  I am currently using BFGMiner.

Thanks,

Paladine
