SLI Question

post #1 of 8
Thread Starter 
Since I may be going 3D surround in a couple of months, I started wondering.

I'm gonna be buying a normal GTX580. However, I may need more than 1.5 gigs of vram, so my question is:

Can I SLI a normal 580 with Gainward's 3GB version?

Cheers

As far as I know, 1.5Gb + 3Gb = 1.5Gb usable.

It WILL work, but the 3GB card will only work like a 1.5GB stock one if you plug a stock card into it.
If you plan on surround, get a pair of 3GB cards, or sell the 1.5GB card to buy a pair of 3GB.

No they won't sli. Nvida always had it set that they have to be the same size memory. Coolbits doesn't work anymore only for older drivers.

Can I mix and match graphics cards with different sizes of memory?
No. For example, an XXXGT 512MB cannot be paired with a XXXGT 1GB in an SLI configuration.
