8800GTS 640mb + 8800GTS 320mb SLI possible?

[imported_karen]

Does anyone know if its possible to put a 640mb and 320mb 8800GTS together in SLI? Also,
since in SLI the memory isn't shared, would it have the same performance as 2 640mb cards in SLI? :lips:

If you flashed your 640MB card with the 320MB bios, it would probably work (I'm assuming, correct me if I'm wrong) But you would then only get 320MB of memory. And no, it would be the same as having two 320MB cards rather than two 640MB cards.

I didnt think this was possible until SLi 2.0?

I thought it was already possible if the cards only differed by amount of video RAM. You would effectively lose the extra RAM on the 640MB card though. I don't think you even needed to do any BIOS flashing.

SLI 2.0 is/was supposed to support SLI among different models/generations. For that work and provide any performance gain, it would have to allow for asymetric configurations and still use all the available hardware resources. So, maybe with SLI 2.0 you would get access to all of the video RAM on the 640MB GTS.

You can't SLI cards with different memory sizes, only clocks. (AFAIK)

Well...with ATI, you can CrossFire two card with the same GPU but different memory sizes (X1900XT 256 and 512)
