HD4870x2 + 3dmark2003 high/low bug

Folks benching 3dmark2003 with HD4870x2 might have come across a yet to be explainable high or low score bug in GT2/GT3 test. Seems I'm suffering from the low GT2/GT3 test bug, so thought I'd do some runs with E8600 @4Ghz - 8x500FSB and HIS HD4870x2 at various GPU/MEM clocks to see how the card scales and whether the low GT2/GT3 score bug exists at all GPU/MEM combinations.

@830/900, @830/925


@840/950, @850/950


Unfortunately, all runs were low GT2/GT3 bugged as I should be some where around 92-96K in 3dmark2003 at those clocks according to some results posted here.

I've tried raising PCI-E to around 105 and not much difference. Tried at 1024x and my windows default 1600x1200 resolution and that didn't help either. 3dmark05, 3dmark06, 3dmark vantage all seem spot on except for 3dmark2003.

So I've decided to wipe my hard drive clean and do some fresh multi-OS boot partitions for winxp pro sp3 32bit and vista ultimate sp1 64bit and see how I go.
