I'm going to try something crazy tonight after the first week of folding is done with this card. I should have a bunch of different WUs to compare the new results with. Maybe drop the core and mem by 25%, crank the fan as LCB suggests and give 'er hard on the shaders. I'm getting a series of those damn dirty 511 point WU's which I haven't gotten in the last 6 days, trust them to rear their ugly heads on the last day of my one week test.
