I'm new to the whole multi gpu stuff. Got my 2 5770s, crossfire bridge attached and crossfirex enabled in ccc. But, furmark gives the same fps rating with one as with two. Also, gpuz reads as my main graphics card having crossfire enabled (2 gpus), whereas on the second it reads as crossfire disabled. Do I need to have two monitors connected or something to make it work? Or is it working and I'm just being a n00b? Thanks
FurMark also has a Multi-GPU EXE, you need to use that for a Crossfire rig. Otherwise use MSI Afterburner to see just what your cards are doing when playing games with a crossfire profile. Should put your mind at ease that it's working then! Also handy for dealing with overclocking and temperatures.
Thats normal. If you want to make sure, you could always do a few bench runs on Heaven or similar with cf enabled and cf disabled to see the performance difference.
