New 8800GTX - Really low performance

I got an OcUK 8800GTX for Christmas and I've just installed it now. I put on the latest 169.28 drivers and fired up 3DMark06, but I got a rather shoddy score of 7,145. Pretty disappointing since my old 7900GTX got about 6,500 with the same CPU. I tried 3DMark05 and got 10,514, lower than the 11,700 ish I got with my old card.

I tried uninstalling the drivers and putting in the 169.21 WHQLs, but that didn't help. Then I had a look at the 3DMark06 properties page and it was reporting that my clock speeds were 108MHz for the core and 337.5MHz for the Memory :(

I've reconnected both power cables for the card but I'm still getting the same low clocks and scores. Power shouldn't be an issue since I've got a Corsair HX620W. Anyone have any idea what's going on?

Btw this is on a fresh install of windows, I formatted a few days ago.

3dmark is also big on cpu by going on yours it looks about the right score its quite a low range cpu nowa days :)
 
check the nvidia driver isnt set to 8AA (override game setting) or something. And check whether pci-e slot is running at x16.

you could do with checking it in another motherboard, i was using an amd system 5600+ or something similar and in a brand new asus crosshair board the score was 6k and with an older asus mobo the score was 9k, all other components were identical
 
Thanks for the replies everyone.

Here's the link to my 3DMark06 score. The lowest scores with X2s at 2.5-2.6GHz I can find are all above 9000 :( I know the CPU isn't ideal for the card, but surely it shouldn't be holding it back this much.

Everything seems fine according to GPU-Z, including clocks and PCI-E speed:

Image quality settings in the drivers are set to "let the application decide".

Unfortunately I don't have another system to test it on at the moment, pretty much all my mates have crappy old AGP systems. The only guy I know with a PCI-E system is in Bulgaria until the end of January...

I'm going out for a while now but I'll try running some other benchmarks later, I'll report back in while. Keep the suggestions coming anyway!
 
sumthign wrong there mate. yours scores:

3DMark Score 7014 3DMarks
SM 2.0 Score 2990 Marks
SM 3.0 Score 3056 Marks
CPU Score 1993 Marks

my scores:
3DMark Score 9550 3DMarks
SM 2.0 Score 4115 Marks
SM 3.0 Score 4649 Marks
CPU Score 2213 Marks

Defo sumthing up with the card. its running nearly half the power of mine, and mines a GT!?

Trobule is i cant advise u on what the problem *** be :-S

Matt.
 
Assuming the GTX isn't overheating and throttling down (check temps and aim a deskfan if they seem very high)

You could also try underclocking the card or defaulting your CPU clock to see if it makes a major difference. If it takes a large dive it may help to indicate it is your CPU.

AFAIK CPU bottlenecking can also cause low SM2/3 scores as well, I still think that's the culprit.

I really don't think the CPU should be this bad, here's a link comparing mine to another AMD X2. He's got a 4200+ at 2.65GHz, I've got a 3800+ at 2.60GHz. He gets 9,461 and I get 7,041. My CPU score is actually a tiny bit higher than his!

I'm running ATI Tool's artifact scan now and my temps have maxed out at 85 degrees. Seems reasonably high but within the safe limits for the card? Cooling shouldn't be a problem since I've got an Antec P182 with 4 Sharkoon Silent Eagle 2000 120MM fans.
 
Do not , please , be insulted by the next ? But it's the kind of trick I've pulled myself.:D

After re-install of windows did you install m-board driver?
 
make sure it's set to "performance" in the nvidia tat

also make sure that your old gfx card drivers are uninstalled
 
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. :)
