To my knowlege you can't and it would be pointless as you would be limited to 1.5gb vram. Best to go with 3gb+3gb or 1.5gb+1.5gb.

I've never seen it done

But i think it would be possible, you might have to flash the 3GB card to its 1.5GB equivalent BIOS before hand.

But as i'm sure others will point out, you will have 1.5GB total to work with. Worth it so long as you don't plan on going NVsurround

You'd turn that very expensive 3gb card into a silly expensive 1.5gb card.

Exactly.


NVIDIA has been on/off about supporting it... but it should work but may need some manual tweaks.
Once again...

Yup. It would defeat the purpose of buying a 3GB card to begin with.
