ATI 6870 X2 Tri-Fire?

post #1 of 21
Thread Starter 
Anyone here of this being done yet? None of the 4 reviews on newegg have anyone doing this. I was curious if it is for sure possible (and also want to know how efficient it would be).

By trifire, I of course mean using my existing 6870 in one PCI-e 8x lane and the 6870x2 in a PCI-e x16 lane...

It's because you can buy a 6990 for the price of tri-6870s I believe

True, but considering a lot of people already have one 6870 and the x2 should come down in price over the next few months (already down to $450), I think it is worth considering

The question is whether the drivers would even let 6870 tri-fire work. AMD only tests for 2-card 6870 crossfirex.

This is why I am trying to find info on someone attempting (even failing) at this.

PowerColor has a single-slot 6870 with two fingers allowing for trifire, so maybe you could shoot them an e-mail to ask?

the drivers do support it, so i say go for it

Biostar had a 6850 with dual CF fingers, and people were able to run 3/4 of them in CF. since the 6870 is pretty much the same, it should/will work.

Yeah. I might have to. The internet needs someone to do it first and post benchmarks! Might as well be me...

Yes, trifire works. AMD wasn't like nVidia was to EVGA, and coded tri-quad fire for them.
