Will these 2 cards work in SLi?

Jul 20, 2008
I know in order to have SLi function properly you need to have the same 2 cards. However, I was wondering if the following two cards can be used in SLi (notice the different core clock speeds and model numbers):

Card 1: http://www.newegg.com/Product/Product.aspx?Item=N82E16814130416
Card 2: http://www.newegg.com/Product/Product.aspx?Item=N82E16814130339&Tpk=evga%209800gtx%2b

(also, don't worry about the mobo situation, I'm sure I have a board that is SLi compatible with 8x8 ports)

Thanks guys
Indeed they will. I have 2 GTX 280s from totally different brands (one's pure reference from a Dell XPS and the other's a BFG) and different stock clock speeds. They work fine in SLi. I make their clocks match in Rivatuner though.
Any difference in clocks and you're going to have them both run at the slower clock speeds.
You can use different brands of nVidia cards for SLI provided that they are the same model.

Example: EVGA GTX 280, XFX GTX 280=SLI

You can use different clocked versions of nVidia cards for SLI as long as they are the same model. Bear in mind that with this setup, SLI will default to the slowest GPU clock frequency in your setup.

Example: EVGA GTX 280 FTW edition (clocked 670mhz), XFX GTX 280 (Clocked 602mhz)=SLI running at 602mhz. You can overclock the slower card to match your overclocked card to run at full speed.

You absolutely cannot use different models of GPUs to run SLI though.
