7970Ghz Ed. And 7970 Original

[p_monks33]

Can you crossfire the two of them together? I have looked around and not heard anyone say. 7970ghz edition has the boost and regular 7970 does not.

I would assume you could, but the ghz edition will run at the clocks of the normal 7970.

crossfire has always allowed you to mix and match cards so I assume you are good to go.

Flash the regulair card with the GHZ ed bios and problem solved. Just make the normal GHZ ed card the main one.

If I remember correctly as long as they are the same generation of card you can do this. The 7970 GHZ is kind of a strange instance, it could be considered a new generation of card, but their naming scheme is REALLY lacking in this case. If they would have named it a 7980 or something a lot of confusion could have been avoided.

I figure that it will work, just wonder if the boost will be disabled on the GHZ ed card.

My understanding of crossfire is that if the cards are able to be CF'd the GPU clock will be the lower of the 2.

If thats the case I am going to crossfire my 7950 and my 7750.

Nope.

 

[VulgarDisplay]

Nope.

The clocks may be different, but they only run as fast as the slowest GPU, and only utilize the amount of RAM from the smallest GPU.

Yes. You can also get a classic 7970, flash the BIOS to a GE, and then crossfire it.

Well, you can save some $$$ that way.

Not necessarily: you can run asynchronous clocks and you'll see a performance boost over running both at the lower clock.

Nope the GPUs does not run at the slowest.

It doesnt have to be same gen, 5770 + 5750 + 6770 + 6750 would work in a quadfire setup. Itd be strange though.........

That's because the 6770 + 6750 are re-brands of the 5770 + 5750.

 

[RussianSensation]

I thought it was a lot more stringent than that?
