I'm planning to go SLI for my new computer, and I had a few questions: 1) Is it okay to mix and match SLI-ready cards? Persay, a GeForce 6800GT 256MB and a GeForce 6600 128MB 2) Does it matter if the manufacturer of the cards are different? Persay, eVGA and XFX Thanks!
You cannot mix a 6800 and a 6600 In theory it should not matter about manufacturers but try and keep them the same anyway. Might save you some hassle down the line.
1) No 2) Yes The Cards need to be EXACTLY the same, same manufaturer, same model, same everything. A Leadtek 6600gt wont work with a Leadtek 6800gt A Leadtek 6600gt wont work with an MSI 6600gt there is probebly a few exceptional cases where people have matched too slightly odd cards and got them working in SLI, but for the most part, they do have to be exact
And buy them at the same time, because manufacturors change things slightly every so often. Tiny things such as the type of plastic the fan's made out of or the density of the silicone, but they matter.
I would recommend that you buy them in a pair. Not just two at a time, but by a bundle that includes two SLI ready cards. It guarantees that they're the same revision, and it might save you a few bucks.
:/ It makes no difference, they just randomly grab 2 cards and stick them in a box. Just like pairs of RAM, its exactly the sam eas buying 2 seperatly.
I didn't make it!
not only can you not mix types of cards (6800/6600) but even from the same manufacturer you MAY have problems if they changed ANYTHING about the card.... also make sure that both cards are running off identical drivers. Most cards today are sold with an "SLI ready" gaurontee that says like cards from that type/brand will play nice. I have an SLI board, and I'd say that I'm quite pleased... I only have 1 card (6800) but Im told if i throw another eVGA 6800 into it, it will be just fine... i think nvidia has a site that tells u compatable cards even.
also make sure that both cards are running off identical drivers.
uhhh... you only need to install drivers once. Just because there are 2 cards you do not need 2 seperate drivers.
but you do need the same manufactorer aswell in 99% of cases its not just the model that needs to be the same

I doubt that the size of the fan will have any effect on how compatible the card is with another.
