My EVGA 6800 Limited Edition is running very slow!

[yhelothar]

I just got the highly acclaimed eVGA 6800 Limited Edition 256MB GDDR yesterday. I installed the 66.81 drivers, which I previously used for my 5900.

I ran 3dmark, yes I agree it's a poorly made benchmark, but it's good to compare against the same cards. I confirmed that AA/AF is off, and it's set to high performance mode.
On my old 5900Ultra, I got 15k on 3dmark2001, and on my 6800, I'm only getting 14k!

I ran 3dmark05, my 5900 got 1K, and my 6800 is getting 2.4K, while I see other 6800GTs getting 4.5k for the same setup, 2.3GHz AthlonXP, and my 6800 is clocked at 350/1.1

I ran farcry at 1600x1200 2xAA/2xAF, river level, and it's pretty choppy, i'd say around 15-25fps, much lower than what anand tested, 35fps @ 1600x1200 4xAA/8xAF

I played quake3 @ 1600x1200 4xAA/16xAF, and I only got 90fps, seems a bit low for this card, considering I get the same results with my 5900 at 8xAF.

Richard burns rally was a tad bit choppy at 1600x1200 4xAA/8xAF, whereas it ran buttery smooth on my 5900@5950 at 16x12 2x/2x

Nalu is a bit choppy at default settings(application controlled AA/AF, 1024x768). I'd say it's running at about 15fps.

So what's wrong here?!

Which driver are you using? I'm using the 66.81's and get about 4700 in 3dmark05 with same card(mines at 370).

 

[yhelothar]

Just updated with the driver version

 

[Vallybally]

Hmmm, this is of interest to many of us with that recent hot deal. Can you give us more specifics on your computer components? Also your drivers. Did you thoroughly remove your old drivers before installing your new card? And tests run at stock speed? Does everything seem ok (# of pipes etc) when you check via RivaTuner or other scanning software?

 

[Cannabis]

What about your AGP aperture size in your bios? Don't know if that would cause a slowdown though.

 

[yhelothar]

I think the AGP aperture size is either 512 or 256MB.
Yes rivatuner reports that this card is 16x1 6vp.

Only thing else I can think of is maybe turn off fast writes.

Set the size in BIOS to 128MB, make sure AA/AF are application controlled, and perhaps try turning of vysnc. The last of those 2 options are right there in the nVidia control panel.

 

[Ironmanstl]

That is low...

you r right
you should be getting 4500 to 5000

all I can think of is run riva during the bench and make sure it is holding its speed and not overheating

good luck

 

[yhelothar]

The thermal sensor is broken, it's stuck at 98C, so maybe it's throttling? But it says it throttles at 120C.

 

[Marsumane]

Try running driver cleaner and then reinstalling the drivers. Just a guess. Also check to make sure its clocked right.

 

[yhelothar]

hmmm my fillrate is VERY low, it might be explaining why my card is running so slow

Maybe there's really only 12 pipelines free and rivatuner is misreporting there the 16 pipelines?

Before I installed mine using the 66.81 drivers, I had a 5700U in it. I removed the drivers and ran a cleaner. then shutdown took card out and installed new one. I then ran the forceware driver setup. My results where.

Doom 3 - 1280x1024 med settings - 63.4fps
Aquamark3 - 58,546
D3mark05 - 4260


I am not OCing at all on any part of my system, does these numbers seem right then? I think they do, every game Ive played so far its been smooth and looks awswome, even AO which is laggy as heck smoothed out quite abit.

 

[Vallybally]

Why these high AGP aperture sizes of 128+? My Abit IC7-MAX3 defaults to 32mb there, wth lol.

Is there some technical articles that explains this setting and appropriate level?

Google has what's called a "search function"

I just tried that. I uninstalled the graphics driver from add/remove programs, then rebooted.
Then upon reboot, I ran driver cleaner and cleaned it all out. Then I reinstalled the 66.81 drivers.
I rebooted after installing it then ran 3dmark05 upon bootup
2250 3dmarks

I'm calling eVGA

 

[IceMole]

Uninstall from add/remove, disable or unplug your network card, reboot in SAFE MODE. Run driver cleaner and clean the cabs just to be safe also. Try using the 61.77s off nvidas site. Also try reinstalling your chipset drivers.

 

[yhelothar]

and how is that supposed to help?

 

[scorp00]

I'm having the same problem with the same card. If you find out how to fix it, let me know. I'm getting 11.2k in 3d2k1 and doom3 at 640 x 480 is choppy. I haven't tried uninstalling and using a cleaner yet as I didn't have much time to play around with it last night.

 

[Viper87227]

mine should be waiting for me when I get home....time to pray i dont have the same problem.

 

[CraigRT]

Sounds like the type of problem when someone doesn't install the mobo drivers/ and/or the wrong order of drivers were done during install.... but that's just what i think when i read that..

I'd consider re-installing your chipset drivers, and then re-install DirectX.

 

[BF04]

Have you guys been able to find the problem?

One thing to look as it seems you need a really good quality PS. What type of PS are you using and are you using dedicated lines to the vid card.


One thing I really like about the OCZ PS is that it has special shielded dedicated lines for vid cards.
