Crossfire is not working

[DoctorRockGames]

So it has been about 5 days since I got my 2gb Sapphire HD 7850 from Newegg. I was planning on doing a crossfire setup with my other Asus 2gb HD 7850 but after days of trying to get it to work, I have not been successful. I would appreciate it if someone could help me. Battlefield 4 beta comes out in a few days D:

What does it say when your trying to enable it?
did you restart your PC after you update your drivers?

I restarted my pc and now it is enabled, but when I go to configure it the second card has 0 activity 0 GPU Clock 0 Memory clock and o Temperature

Thats strange, never heard of that problem before. did you disable ulps in the registry?

How would I go to the registry? Lol, I feel really dumb asking that question

Never mind the other comment, I changed EnableUps to 0 and it works, thank!

No problem

Have you tried un-installing and re-installing drivers?
also do this
Go to registry and disable Ulps:

[HKEY_LOCAL_MACHINE\\SYSTEM\\ControlSet001\\Control \\Cl ass\\{4D36E968-E325-11CE-BFC1-08002BE10318}]

and change "EnableUlps" to 0 under the 0

Have you tried any other games?

whats the rest of you Specs?

have this running in the background while playing and check to see how both GPU's are doing

Hi. I am having similar problems as this other guy. Just got two new 290's. tested individually. Work great. Put in Xfire and fan of one Sapphire TRIX does not work, when in W7 desktop. But when I try games, the fans spool up. Also, both GPU's getting really hot. I suspect it is due to ULPS.

I downloaded ULPS configuration utility. It came with various options. I selected disable ULPS but response came back file not detected.

How do I disable ULPS when I cant find the file?. Please help!. Thanks.
