My best setting so far is 882KH/s. 920/1500 TC 32765 -g 1. Still havent had time to mess with -g 2, but the only way I can get -g 2 to work without hw errors at 800kh/s or more is with TC at 22550ish or higher. -g 2 needs intensity of 19 or 20 with this card, not 13 like a 7970. These don't configure like previous cards at all.
