Ati 5770 help

post #1 of 9
Thread Starter 
I have 2 ATi 5770s installed in my new gaming PC but the problem is, the second one will randomly go to core clock of 000Mhz and memory clock 000Mhz, I also cant control the fan on the GPU with CCC. Restarting the computer is the only way I found to fix it. Any ideas?

try wiping all your drivers and reinstalling them.

Nope didnt help.

Are there any programs that might cause this?

The clocks u seeing are the clocks during the time you checked them, since you have 2 hd5770s in crossfire you are only monitering 1 card which was inactive at the time. Try checking the other card.

Well i didnt think of that, but the first gpu is at 157/300. most of the time the second one runs at 157/300 too. also, I cant control the fan which is why I dont think its that.

Okay nevermind, you were right, when I started a game it turned on. Is it some kind of power saving thing? If so is there a way to disable it?

Update: Found a fix. "ULPS" http://www.overclock.net/ati/667144-...ling-ulps.html

No, it is simply that at the time that you were using it there was no program that utilized the graphics card therefor the graphics card did not need to have high frequency clocks at the time. While you are playing a game or editing a video, though, the graphics card will go to the target clock you have placed. You need to turn off automatic fan to control the fan. To do this check the manually fan control option and check the box, but I do not recommend putting the fan at manual control.

No no, what it does is disable ULPS which is a power saving option for the graphics card. So now the card doesnt go off.

And I gave rep.
