Can I put two different brand Gpu?

Deazlee · Aug 10, 2014

Hey there,Can you use two different branded GPU's in SLI? I Currently have a 3GB EVGA GTX 660 and was thinking of getting another 1-2GB Gtx 660 different Brand to put in sli. Would the 2GB affect my 3gb? If it does, is it worth it or does it not matter at all.|

This is the GPU i currently have.

Which one of these in this list below is best suitable to SLI with my current GPU. ( besides the one that i already own)

Brands dont matter, nor do clock speeds. However they will have to have the same amount of Vram to run in SLI.

Both cards will use the lower of the two capacities.
e.g. if you run a 2GB card and a 1GB card together, both will use just 1GB each.

Hey man, thanks for the very quick response!

This is the GPU i currently have.

Would this be a compatible match for my current GPU without stressing the other one out so they both sync at 3GB?

Try and get another 3GB card, it's not worth the headache if the cards have mismatched Vram. There was a time when it seemed to work but I have seen too many posts where that is no longer the case.

If you get a 2gb 660, the 3gb 660 will only use 2gb to match the other card, otherwise it will work fine. If you are playing at 1080p 2gb vram is enough.

That used to be the case with a couple of exceptions but not anymore from what I've seen.

byza :

3GB is not an "official" loadout for a GTX660 and even if it was the maths don't work that way.

Yes that is even better. However it would be good if there are from the same manufacturer. But it will still work.

Don't want to fork out the extra 50$, i'd assume having the same gpu would be better but moneys tight nowadays, trying to squeeze some pleasure out of life while i can. Thanks for your answers, very much appreciated!
