Okay, sorry if this topic has been discussed too much, but I've read too much already, with no decent answers.

I have bought myself a XFX 7800GS Extreme Edition last week. I plug it in my computer (who had run a XFX 6800 Ultra a few months before, so PSU should be good enough).

I install the drivers (after having removed all the old ones). All good, I update to the newest drivers: after reboot, a minute or two later (so when everything is finally fully booted) my CPU goes on 100% and my screens shakes and turns black randomly and comes back etc. Task Manager says it's task manager that runs at 100% ... riiiight!, as if
Shutting down task manager again, doesn't do shit. Okay, back to the drivers on the disk. They run! Whoohow. But Performance? Hell no!!!! I could run HL2 on full graphics very very decent (and those were recommended settings too). Now recommended is everything rather low and on full the performance is way too low.

I have this problem in all games.

What driver should I install or what is the problem?

I have 460 Watt PSU
AGP Aperture size on 256 MB
Fast Write disabled.

Personnaly, I would start to enable the fast write function, then check these things:


-make your card is running at 8x speed.

-make sure your aperture size is equal than the amount of memory that you have on the video card.

-Try out the NGO Optimized drivers for Nvidia Cards. In my opinion they are the best optimized drivers out there.

-If it still doesn't work, ask somebody else... cuz i think you r screwd

AGP Aperture size doesnt need to be the same amount of memory of your memory card, thats just a myth, its proved that AGP Aperture size is stable at 128 ( but some people says that the least aperture memory allocated better, other vice-versa). ( http://www.techpowerup.com/articles/...ing/vidcard/43 ; http://www.tweakguides.com/NVFORCE_2.html). It seems to be a hard problem, try underclocking your video card, formatting maybe. Or RMA your card see if they find some problem with it.

Like I already said: mobo settings are fine! AGP Speed 8x, version 3, Size 256MB

Same as on my 6800 Ultra

i like to keep aperture at a quarter of my ram as a general rule of thumb

After a full update of my motherboard, I have achieved quite an improvement. Latest drivers run stable, in-game performance is a bit boosted

BUT

performance is still too low.

Besides: temperature is only 32°C, which is abnormally low for a GPU of XFX

hi there, i have a xfx 7800gs extreme and had some problems with me card 2.. what i did? well first i used ngo driver.. ran pretty stable and got good preformance, but my temps went 60C in game with ngo drivers. used that a while and couldnt play oblivion at all (part of the heat but also caus my processor is way to slow).

then the new nvidia driver came.. 91.47 i believe.. to lazy to go and look. they run fine.. getting myself an new mobo and proc

BUT! make sure you update the latest chipset drivers for your mobo and agp chipset and stuff!

everything else look pretty good @ your set up so it should work perfectly.. but remember that this card is a master of disaster.

I finally managed to run the latest drivers stable. Issue was my NForce 3 chipset. Update of it fixed it

BUT

performance is still way too low. This seems to be due to the so called "cold bug" (idle temp below 38°C).

I'm trying a fix right now. I'll tell when it worked

You probably do not want to hear the fact that there are not very many people who know enough about eliminating every reference to the old driver install from your 6800 that will keep you from reinstalling your OS. I have seen a million posts like yours with people just doing a basic driver uninstall and swapping out the card and getting really limited performance. Some chipset drivers and BIOS are better at detecting the new hardware than others and results will very but if you want the full potential of your new card to be available you need a fresh install of your OS.

normal solution would have been using nibitor (2.8 or higher) and disable temp monitoring and then flash GPU with nflash. but for some reason, I couldn't disable it. Solution was NGO Optimised Driver
