The problem is that in crossfire mode, do not scale well to overclock more than 1000/1375.
separately 1200/1600.

You need more volts in Crossfire to achieve same clocks than separately, noticed this myself aswell. My cards does 1100/1600 separately @ 1.075V, but in Crossfire they need 1.175V.

Hi All

I've got 2X 5770's at the moment, but something isn't quite right, According to CCC my Crossfire is enabled, but according to GPU-Z it isnt, also when I run any stress test (Or game for that matter) the second card remains Idling at 0%... Pulling a big W*** T*** F*** from my side.

Not sure whats happening and any help will be greatly appreciated

Thanks

update: Got experimental so i swapped the cards to test if the 2nd one was dead, when booting into windows got an error from catalist saying "No AMD device installed" and the drivers were doing funny things, so i reinstalled drivers and rebooted, now whenever i stress test GPU 2 does all the work and GPU1 idles, but my screen output is via GPU1....

BTW: Using MSI afterburner to monitor things and OSU! to test... only cause its fast to load tongue.gif

This is relative to a current problem i have, since last night i have had huge what i only know to describe as artifacts, i have decided the crossfire bridge has gone bad so removed a gpu until the new one arrives, anyway i have only ever tried to oc my gpu`s in dual config and never had any success over the factory gigabyte oc regardless of voltage. Since being on single gpu this morning i attempted to clock it again and had success, the single card has clocked to 1200/1450 easily from stock 1100/1200. I now need to test the other card on its own to see if that was holding the crossfire oc back or not, be interesting to see if the other also clocks the same in single config.
