Can I SLI two cards with different VRAM Capacities?

post #1 of 5
Thread Starter 
GTX580 1.5gb + GTX580 3GB = 4.5Gb total VRAM?

Is that even how SLI works? Thanks OCN

^this.

SLI ram is mirrored so you will only have 1.5GB vram effective for both cards. (always matches the one with the less ram/ slower speed ). Crossfire works the same way.

You can SLI them, but will only take advantage of the lower of the two cards' vram.

So in this case, only 1.5gb usable. thumb.gif

Like others have said. The lower amount will be used for each card.

So as long as your not spanning across 3 screens you should be fine.
