5970 performance problems..

Hey all, I got my 5970 about a week ago, and have been using catalyst 10.5. I tried 10.6 however that driver screwed up my display. so I uninstalled it and installed 10.5. I have been able to run DIRT 2 at 1920x1080 maxed out with vsync on at 60 fps.

After starting it up again yesterday, I noticed slight freezing when going though menus and loading screens. I ran the benchmark test and found that my minimum was 32 fps, but the previous day was 59 fps.

How could performance drop if I didn't install anything or change any settings? Is there a way to check if the cards is being used completely?

Thanks.

did you use driver sweeper when you removed old drivers? if not then use it and remove the drivers and then install the new driver
download gpuz and see the clock speed at which it runs when you do benchmarking it should jump from low power clocks to high clock

I am running windows 7, running driver sweeper is not necessary, you can just delete the ATI folder and install new drivers. I did that anyway, and I still have problems.

Okay there is a problem..

According to GPU-z

One GPU is running at 730mhz. and the other at 157 mhz. One memory clock is 1000mhz, the other is 300mhz.

One of them is not being used properly..

idle or full load ?
July 3, 2010 7:18:36 AM

Oh and GPU load is at 0% for both...

Wait,
Launch a game and play for about 5-10 minutes, then minimize the game(and check the clocks of both cores)

How do i check?

I am running DIRT 2 at the same time.

I have DIRT 2 running at 1920x1080, on ultra details. Clock speeds are still what I said before.

just use driver sweeper , remove old drivers and install new one..
i still think its a driver issue

I already that, however I might try 10.6 again...

I have a Gigabyte 5970 running the latest drivers and im having the same issue as mentioned above under load.

My specs are:
Antec TruePower Quattro 1000W TPQ-1000

Microsoft Windows 7 Ultimate 64bit

Gigabyte ATI Radeon HD5970 2GB

Gigabyte GA-X58A-UD3R Motherboard

Intel Core i7 930

Western Digital Caviar Black 1TB WD1002FAEX

G.Skill PI Series F3-12800CL7T-6GBPI 6GB (3x2GB) DDR3

And yea in game it has relaly poor proformance. One gpu on bout 732 and the 2nd on 132 any ideas guys ?

the 5970 has two GPU's, does the game support this? maybe this could be the problem, once the one GPU is pulling to much than it will let the other GPU for some "help"....

maybe the game doesn't support dual GPU simultaneous processing?

just my thought

since technically a 5970 is pretty much 2 5850s on one pcb, it doesnt really suprise me that one gpu is basically idling for all intents and purposes, my 5850 maxes out DIRT2 at 1920x1080 on ultra settings, and typically stays around 60 with vsync on, so unless you hit a really rough area i dont see why the 5970 would use both, especially since you are essentially "capping" your framerate, now to the original post, im not sure why you have a sudden decrease in performance, could be many things, but if you installed the card like new then i dont see how it could be a driver issue
