Title: Can I Crossfire XFX 6970 And HIS 6970?
Post by: EnGineer on June 28, 2011, 11:45:36 AM
Hi,
First Time I Am Building A Rig And Don't Really Understand In The All Crossfire Thing...

I Am Buying A XFX Radeon HD 6970 And Also I Have Found In A Really Good Price A HIS Radeon HD 6970 So I Wanted To Know If It Is Possible To Crossfire Two Cards From A Different Brand?

Thanks For Replying,
Ray

Yes you can crossfire two cards from different brands, but you don't need to for mining.

The cards should perform better if you don't crossfire them.

Be wary about the XFX cards, they are the cards I detest in my mining rigs. My XFX 5850s run much hotter than other brands I have and they were the worst when it came to overclocking. My asus and sapphire cards perform the best. Not sure about HIS, never had one.

Oh, thanks for the info.
Good to know they will work fine on crossfire but are you sure it will be better NOT to crossfire them? Also for gaming purpose?

Yes, I am sure that you will get better performance when mining if you disable crossfire.

Crossfiring = 1 cable going from card to card and an on/off switch in the settings. Nothing to lose sleep over. Play with it when you get them and see what works best.

Search this forum for posts mentioning the same brand/model card as the ones you're looking at and see what they're doing.

What OS are you going to run?

For sure am going to play a bit with the cards and see whats best... :-)

As for now, I am going to have a x2 HIS Radeon HD 6970 (Crossfire OR not) working on a Windows7 OS.

Thanks for your prompt reply.
