5850 xfire overclocking

[ossian]

Hi

Got the 2 cards running sweet at stock in xfire, tested around 6 games no probs off and on for 48 hrs so machine seems stable, I ran Trixx 4.01 last week with only 1 card in the machine with no probs, now when i try to change any settings the machine freeezes completely.....

Any ideas?

List your specs and we shall see

Try taking one card out again, see if it works. Just to rule out that it's something else that changed around the same time.
