i already have a 6950 in this computer and want to put a 6970 in it too. would this cause the 6970 to run slower or what? or maybe crash?


the 6950 is a stock card that can't be unlocked. so it will have less shaders than the 6970.


i ask this because i heard it is best not to mix cards in the same system but these cards are very similar so may be ok?

You shouldn't run into any issues when mining either in Linux or in Windows.

If you were playing games, the 6970 would throttle back to match the 6950 so the game would play in sync. When mining however, each card works independently of each other and will go as fast as it can.

Hope this helps!

"Generation" was an issue for me under Windows, as I was unable to mix 5xxx and 6xxx cards and install proper drivers to get mining. The AMD CrossfireX Compatibility Chart illustrates which combinations are supported.

However this has not been an issue for me in Linux; I have a rig with a 6950 and 5850 and each is mining to capacity.
