I have a pair of BFG 6800 GT OC cards in SLI and it seems coolbits fails at whatever speed I put it at, even underclocking. The cards run good and score great at stock speeds, just can`t understand why they don`t OC at all, not even 2MHz.
a3500 @ 2.8GHz
A8N-SLI
True Power 430 volt mod`d on all rails
OCZ PC4200 (beta sticks)
71.84 drivers

any ideas??
Thanks for any imput.
