SLI cards with different amount of ram?

post #1 of 8
Thread Starter 
Hey,

I'm currently using a SLI setup of 2 reference gtx 570 cards. I want to go ahead and add a 3rd for a 3-way sli. The 2 cards I have have the 1.5gb memory but I'd like to buy the one that has 2560mb of ram. Is it possible to run a 3way SLI this way considering the different amounts of ram?

Edit: Just read the FAQ derp should have "used the search" lol. Has anyone out there in OCN land got this to work?

I believe it is possible, but it will effectively only utilize the total amount of RAM on the lower card. So while you can do it, there is absolutely no point.

Yep. It will scale down to the smallest frame buffer (in the case of 570s 1.28GB). No point in buying the 2560MB version in that case.

It will work, but your card with higher amount of vram will only be able to use the amount of vram that is available on card with the lowest amount of vram. So in your case, the 2560mb card will only be using 1.5gb of that memory.

Thanks guys, I just read that info all over the place just now lol. Definitely feel like the search noob tonight. Sucks though I really wanted to throw in that bigger card. C'est la vie.....

EVGA GTX 570 2.5gb is non-reference design.

i think so, but you will be unable to use the extra ram as sli will use the lowest amount of ram
