Today a friend of mine bought a new 4870x2 card . An Asus one to be more specific.

So ... We plugged the card and tried 3dmark03 . First run at 800Mhz core gave us about 740fps at GT2 . I started o/cing the card and at about 850 it crashed .

I turned the PSU off ... and then on again ... booted in windows and run again GT2 at 800Mhz core . Result ??? About 850FPS GT2.

I shut the computer down again . PSU off ... and then on . Run again ... and GT2 at 740FPS.
Again the same story . Shut down ... power off and power on . Run again and 740FPS GT2.
And again I power down the PSU ... then on again ... and this time we got 850FPS !

Powering down the PSU is the key for fast 3dmark03 runs in our case .
