Mixing two brands · DIGIT-ARC

V

Currently i have XFX ATI hd 6870 graphic card. now i want to put it in crossfire. so the next 6870 card has to be made by xfx only or can i buy someother make such as Asus.

thanks

u can pair any 6870 of any manufacturer.

it's not depend on brand, it depends on serise only .. So you can cfx with any brand but it must be 6870 only.
BTW what cpu and psu do u have ?

Op can even use a HD6850 to CF with his HD6870.

BTW, Op has i7 950 cpu and he is probably going to get a tx 750 v2 ;-)

@OP: You can use 6850 or 6870 from any brand to crossfire.

And please do mention the PSU you are using.

Try to cross fire with same rated cards. If you join an 6870 to a 6850, the former will run at the speed of the latter. Else do not.

Yap, u r right, rather i should mention 'any 68xx gpu' .. But in cfx gpu will work in lower clockspeed (which gpu has lower clock). He can oc to match gpu clock though.

two HD6870s can run with their own clock speed - no need for down clocking ;-)

Regarding Crossfire, HD 6870 and HD 6850 can be crossfired and they will work as per their own frequency. Unlike SLI, in Crossfire both the cards can work at different Core and memory clock speed. So HD 6870 and HD 6850 will work at their own frequencies, 6870 won't be downclocked to HD 6850's clock speed.

thanx all for ur responses. Thank u very much
My cpu is core i7 960
Psu is corsair tx850

Ty

Cilus, I think they will be downclocked.
