Nice work eva, very nice indeed

I have not tried this but I have read around the traps that these cards are scaling very well and seem to be quicker in Vista 62 than XP. Be nice to see a comparison

thanks

Yeah read about vista being better for 4870x2 so definitely installing vista and will try some 4GB DDR3 benching too

edit: Vista Ultimate SP1 64bit installed, first run on 3dmark vantage at stock cpu/stock card

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.

Interested to see what you find. So in some cases a small PCI-e Freq increase can help or were just exploring this as well?

pci-e frequencies sometimes help depends on board, i hear for P45 they don't like pci-e frequencies set too high though

Fresh OS installs didn't help with 3dmark2003 low GT2/3 bug Anyway, using XP SP3 now for 3dmark2001 and this looks better than Vista 64's 70k score hehe

3dmark2001 @850/950 = 97,916
3dmark06 @850/950 = 23,806



Not bad for dual core 3dmark06

Awesome work eva. Tell you what I was having issues with my SM2.0Score recently and it had dropped out from ~53xx>>>44xx and I was thinking this started with the installation of 8.9. I found these modded 8.9 drivers on Guru3D http://forums.guru3d.com/showthread.php?t=274344 and my SM2.0 is back . Not sure whether it was driver install issues with 8.9 or an XP64 issue?!? Now they are back and time for some benching runs gotta try and get 15k on my lowly 4850.

thanks mate... interesting about the difference from drivers could be XP64 as i hear it ain't that great for 3d compared to XP 32bit ot Vista. What drivers you use prior to 8.9 ?

I was using 8.8Cats, but did read the release notes of the 8.9's and noted a specfic sub-section for XP64 but nothing specific to my problem. The new drivers are working well and have just done 7 runs with some interesting results.

I am curious how you bench your card to find asymptote (just purely for benching runs)? Your CPU guide has become my gospel but interested about the GPU. My results are a bit erratic but show some strong and interesting trends. I think I have found my GPU RAM hot spot as I got a nice spike but not really sure if this is correlated to ambient+operating temps?
