I read somewhere that maybe disconnecting and reconnecting crossfire a few times syncs them and it seemed to work (however at this point i think it may have only fully using one card still). I jump on today and its running smooth in crossfire but only using one card fully still it seems (low usage and other specs on other card) so i tried disabling ulps with that resulting in the second gpu usage increasing during game but only seeming to stay around one cards performance ?
I dont know much about crossfire or amd cards (graphics cards in general) and am wondering what i can do to get them performing optimally ?
usually amd cards will perform great on crossfire
i havnt seen a problem with my 7950 crossfire yet
i have a feeling for the new R9 200 series the powertune setup hasn't been done properly
since the powertune tech requires on temps and TDP to boost i have a feeling theres a bug in the software
