New 8800GTX - Really low performance

[johny dolan]

When i first got a gtx i had a x2 4600 and my 3dmark06 was 8500 but same card with a e6800 will do 10700 and even more with a quad core.3dmark needs cpu for a big score.Bottleneck wont be such a problem in games just run as high a res as you can and crank the settings and the cpu bottleneck will dissapear.

Do not , please , be insulted by the next ? But it's the kind of trick I've pulled myself.

After re-install of windows did you install m-board driver?

I did, I'm not quite that bad

make sure it's set to "performance" in the nvidia tat

also make sure that your old gfx card drivers are uninstalled

I tried setting it to performance and I was getting basically the same results, I only did the first test but it was chugging just as badly as with the previous settings.

I did a full uninstall of the old drivers with Driver Cleaner .NET before putting in the new card.

I would make sure all 16 "lanes" of the PCIe bus are being used. CPUZ shows this or check BIOS. I've heard of some people having to increase bus speed by 1 mhz to get full bandwidth.

CPU-Z is saying that both "link width" and "max supported" are 16x in the graphic interface section, I presume this is what you mean? I've had the bus at 105MHz since I got the motherboard as well.


I did a couple of game tests and got some interesting results:

F.E.A.R (1920x1200, All Max Settings, 4AA/8AF, no soft shadows): 63 FPS Average

Crysis (1280x1024, High Settings, 0AA/0AF):

30FPS seems just about ok for 1280x1024 but a min FPS of 9 is pretty horrible.

F.E.A.R on the other hand seems grand. Any other games I should try that people could compare their results to?

I'm using an nLite install of windows, which could have something to do with the results. I was pretty conservative with what I took out though and I've done about 5 previous nLite installs with no problems before this. If I can't figure out what's going on I might do another reinstall of windows, not customised this time.

Reset your BIOS. If that doesnt clear up some miscellanious settings that may help, then I suggest a reinstall of windows. It may not help, but worst case scenario it removes the OS or software as a posiblity.

Finally, a decent score!!

I reset the BIOS as Stabhappy suggested, but that still didn't do anything. As a last resort before a format I switched back to an older BIOS and for some bizarre reason it helped.

Now I'm getting 9,637 - much more like it

Thanks for all the help everyone. Now I can properly settle into some UT3 and Crysis...
