Title: Can two different NM, series GPUS work together?
Post by: lightlord on November 02, 2012, 11:27:15 AM
I am asking you, do you think a 7970 and a 6950 would work together?
One is 28NM other is 40NM?
What problems or reasons why it wouldn't work?
Can it work on the same board together?

Yip, They'll work together.

I actually have a 7970 and a 5870 working on the same MB.

P6N Diamond w/ a 6870, 6770, 5830 crunching together in perfect harmony. There's a song in there methinks.

Did you know that the 2nd card does not need a monitor or dummy plug ?

Works fine I have that combination in one of my machines 6950 first card 7970 the second due to the width of the cooler on it. Nothing special you have to do other than make sure your running the sdk 2.6 or newer otherwise the 7970 will not be seen for use by the system.

Same as everyone else said any card combo will work (with compatible drivers and SDK)...

Just one exception in case you were wondering, they will work just fine for mining but don't expect to use them *together* for gaming. You will be able to use one of them if you want to play games, preferably the faster, but you won't be able to crossfire unmatched cards.

I have heard of rare cases that people got unmatched cards to work with driver and software mods but they all took a performance hit.

Just wanted to make sure you understood that part of it ;)

Otherwise go for it, I've even mixed nvidia cards with amd before!

I had to try a few times but got mine to go with the 460se as the main display in the 2nd 16x pcie slot.

Uninstall the drivers/start from scratch and it will work after the fake display is created on the radeon.
