Does sli cards same ram

[Liam-Wabbit]

just a question: setting up a 660ti, do the cards need to have the same amount of ram ? or can I get away with buying one with 1gb less ram ?

no, it just means they will run with the lowest amount.

So if you have a 3gb and a 1gb card together. It will only use 1gb of ram.

didnt Nvidia change the SLI requirements so that both cards must have the same amount of Vram? instead of running at the lowest? Also, in saying that, you are better off getting the 660Ti with the same amount of Vram as its going to be cheaper anyway

stupid how sli only use the ram on the first card any way. just thought I would double check.
I was thinking of getting a second hand 660ti for sli that all

Yes, youare orrect. SLi now requires bot cards to have the same amount of VRAM. This was coded into the drivers. If it detects cards wth different VRAM, it simply won't allow you to enable SLi.

What?? The data is mirrored to BOTH cards. Thats how both AMD Crossfire and nVidia SLi function.

This basically why nVdia made it so both cards needs the same amount of VRAM. You have a....GTX 660 Ti with 2GB, and another 660Ti with 1GB. You can't have one card deal with 2GB of data, and another card only deal with 1GB....since the data is mirrored across both cards.
