ATI cards can be funny when pushed too hard or at the wrong clocks

but he very well may have a card that is capable of benching with stable 3D numbers past 1250 who knows heh

to be honest 1.4v was something i was told recently. i benched 4890s and have returned them since without checking with DMM but if it says 1.488v that should be pretty good for high LN2 clocks
