Radeon HD 7970 / 7950 Crossfire

post #1 of 8
Thread Starter 
I got a XFX Radeon HD 7950 DD right after they got released and i am now thinking about getting either a 7950 more or a 7970 so my question is can you run a 7970 and a 7950 in Crossfire will the 7970 underclock and lose some cores and speed or will they work with the right cores and speed?
And also the XFX DD is loud as hell can anyone recommend a better card either 7950 or 7970 thats makes less noise
Thank You

You can run the 7970 with a 7950. The 70 will clock down though.

I believe they'll run at the same speeds then if you OC. You can crossfire, the same lineup of the same generation (79xx). The only detriment is you have less cores, but I'm sure you knew that. But crossfire will work without a hitch.

Also look at some of the sapphire cards, like the sapphire toxics. They can be quite quiet. Or the ASUS DCIII, the monster cooling setup is extremely quiet.

I am sorry but i didn't understand that will that mean that the 70 card will go down from 2048 cores to 1792 that the 50 card has or what i am confused

AMD cards can work at their own specification (core, memory clocks, voltage and SP/Shaders) in Crossfire. They don't have to downclock or sync'ed, etc.
