any thoughts on how to get 280x's stable with this gpu miner yet?
and why gigabyte 280x's seem to suffer very low hash rate, eg struggle to break 300h/s when compared to an asus 280x that does 360 with ease.
That's what you mean ? Gigabyte like my another rig ?

are they the windforce 280x's rev 1 or 2?
i run 2 of them and one can do 310H/s at 1200/1500 and the other does about 308H/s at 1200/1500. cant seem to push them any higher on mine. even tried different motherboards and the same affect, they are also the ones that drop out 98% of the time....
