Hey im new to the forums and I have a question about why isn't my gpu's not working properly in crossfire mode.
I have a HIS 6850 and a Gigabyte 6850 with a factory oc. I upped the HIS gpu clock to 850mhz and downclocked the Gigabyte memory clock to 1000mhz (getting artifacts with my HIS gpu if I oc'ed the mem clock)
But when I crossfire them I do not see any gains from crossfiring and I tried both 10.12 and 10.10e in crysis, arma2, and bfbc2
My computer specs are
Asrock 870 extreme mobo
athlon 2 x4 3.33ghz
antec earthwatt 650psu
Yeah I already did that and enabled the crossfire watermark to show up when crossfire is working and still no gain in performance. I know both of them are working i switched them and ran both of them alone and same fps for both cards so i dont have a faulty card that i know of
