    2 EVGA 660TI's

    So I have a client who has a 660ti P/N: 02G-P4-3660-BR, and he also has a 660ti P/N: 03g-p4-3661-kr

    One is the 2GB version and one is the 3GB version. Is he able to use both of these together? Or Not possible since they don't both have 2GB or 3GB?

    Yes, but with the 3GB one, it will use only 2GB to match the other one. So you literary have an empty 1GB GB GDDR5 RAM to hook up another monitor :).

    Are you writing about using the cards individually or in SLI?

    In SLI, I've found contradictory statements online, so wanted to see if I could get a straight answer.

    As long as they are the same series is all that matters.

    Apparently you are not permitted to use SLI with nVidia cards with different amounts of VRAM, even if they are otherwise identical.


    I thought that they might permit you to do that, with the effective VRAM being the smaller of the two. Looks like they once offered that, but have dropped it in more recent drivers.
