Title: Crossfire not working properly?? Post by: Zindawg on 12/05/2012, 12:09 PM I'm running duel AMD Radeon HD 7950's, i have xfire enabled and i know xfire doesnt work in windowed mode, but in BF3 i play full screen, on ultra i dont get any fps lag, however, CCC shows that one graphics card is at 100% use, and the other barely hits 20%... i heard that they should both be equally used around 50-60%? I read up that some USB 3.0 Turbo boost in your BIOS can effectively halve the bandwidth, making the second graphics card not do as much as it can, i tried going into my BIOS and i honestly couldnt find that option to disable, idk if that is an out of date option for older version windows or what, i got windows 7 ultimate... so yeah is this normal? is one card meant to be at 100% and then the other kicks in? or is something wrong? cheers for any input

Title: Re: Crossfire not working properly?? Post by: Psych0Kyller on 12/05/2012, 04:17 PM Is there a setting that can enable crossfire that the driver would have disabled when u updated it

Post by: Zindawg on 12/05/2012, 04:40 PM Yeah mate i've checked, crossfire is definitely enabled, the 2nd GPU does get some use, just that its as if it waits for the other GPU to get to 100%, surely it would be better for them to both work equally, and i heard that is what is meant to happen
Title: Re: Crossfire not working properly?? Post by: Alucard on 12/05/2012, 04:47 PM is there a crossfire profile or anything that you can change
Title: Re: Crossfire not working properly?? Post by: Zindawg on 12/05/2012, 06:15 PM Wow... just realised it was at 0-20% when i alt tabbed to check CCC because i alt tabbed... that cancels xfire... i had CCC open when i alt tabbed and they were both at 100%, sorry for this dumb arse post, i feel sickingly stupid atm
