Crossfire gone haywire

[blair]

Hi,

My pc was working fine till it crashed once, and now crossfire isnt working properly. GPU2 when in the desktop or not in games should turn its self off and normally did it had 0/0mhz and 0% activity now though it has 500/1575Mhz and stay at this speed doesnt matter what you do.

Turning crossfire off then on again fixes it till you restart the pc again then its back to having high clocks.

Have you tried disabling ULPS in the registry?

Start>regedit

Tools>find>"EnableUlps"

modify value to 0

Since you are there you might as well enable "EnableCrossFireAutoLink" (set the value to 1). Sometimes that helps too.

done and done second card still stuck at 500/1375Mhz i dunno why it suddenly did this also shouldnt it be completely disabled when at the desktop anyway its what it used to do.

i installed amd application profiles and both cards are now at 300/150Mhz but when everything was working before when browsing or doing anything outside of games etc the first card would be at 300/150mhz and the second card would be at 0/0mhz and would only come on if something used crossfire.

cancel that after restart back to its usual shit 500/1575Mhz

Are you using amd overdrive? When I have it activated in CCC it does exactly what you are describing.

I just reinstalled windows only stuff i have installed are chipset drivers and amd drivers havnt changed any settings nothing and the second card is still clocking its self at 500/1375Mhz

ok now it all clocks down to 0/0Mhz but takes 2 mins from log in.

I found the program that was making my second card stay in2D clocks it was the Logitech G19 drivers the current ones i downloaded the legacy ones and no problems GPU goes back to 0/0Mhz in a few seconds after stopped being used.

Ah, nice to know. It's also known that having youtube videos and other flash based webpages open can cause GPUs to clock strangely.
