Crossfire & Video Memory

[MrKlingon]

If for example I Trifire 3 1GB cards, will that be like having a single 3GB card in terms of video memory available?

Nope, it'll be like having a single 1GB card. Each card's memory will basically mirror the others.

Why can't the VRAM be combined for use by the pair as a whole? What's the limitation?

Most likely just a programming thing. Might be possible.

Same reason it can't be combined with main memory. Too much latency, not enough bandwidth.
