system freeze when second graphic card installed

[Isbre]

Iv been using Everest for a long time but about two years ago i stopped using it when i got a seconf Radeon 5870 graphic card configured in crossfire. I have always used Everest for monitoring mainly and this has worked fine with one card. I tried AIDA64 the other day and still same problem.. I have new formatted windows and have had meny new windows installations sinse last time i swich from one graphic card.

My specs:

Windows 7 x64 Pro

AMD Phenom 1090T

Crosshair 3 Formula

2x2 gigs of ram

Radeon 5870 in CF

Hi ChiefZeke and thanks for your reply.

I believe this is most likely something that must be sorted out by the programmers of AIDA64. I cant see how this has anything to do with the graphic/crossfire drivers.

It seems ULPS causes troubles on your system too You can do the following:

1) Disable Multi-GPU support in AIDA64 / main menu / File / Preferences / Stability. You need to restart AIDA64 to apply the changes.

This however may not help at all, since it is not effective in some cases.

-- or --

2) You can disable ULPS by scanning the Registry (using REGEDIT.EXE) for any occurences of EnableUlps, and changing the value for all those keys to 0. You then need to restart Windows to apply the changes.

You will need to disable ULPS again after upgrading to a new Catalyst release.
