Hello,
I was wondering if i can SLI an EVGA GTX 560 SC 2gb with an EVGA GTX 560 Ti 448 Cores Classified Edition. I figured you could because they are the same chipset...

Nope, 560 with 560 only. 560ti has 384 cores, 560 has 336.

They're different cards. Don't think that just because there is a TI at the end of one that they are essentially the same card, they're not.

No, you cannot SLI.

The SLI configuration is done in the manner when the model of the cards are same irrespective of the company you use for the card.
For SLI you have to have both the card capacity,core clock,cores same for SLIing.

The reasons why you cannot SLI:-
1)Both are different models.
2)The 560Ti 448 is having more cores then 560 SC.
3)Core-Clocks are different.
4)Even the capacity are different.

Thanks for the answer, I'll plan on getting another GTX 560 SC 2gb to SLI in the future.

That will be better for you and good luck for your future SLI configuration.

Actually, Vram and core clock can be different. Then both cards will run at the slower speed (for example: 2 cards at 1gb and 2gb will have a listed dedicated memory of 1gb). The only requirement is for the cards to have the same chipset.

The memory bandwidth also has to be the same, a 256bit card will not SLi with a 192bit card for instance.

and yet, he is trying to SLI 560 with 560 Ti 448. No way that would work, they are based in different architectures. GF110/GF114

The architecture of the GPU's is the same but they are different classes of the same series hence why they have different core counts.

560 Ti 448 is based on GF110 and 560 is GF114. But whatever, even GF114 560 Ti can't be SLI'd with another GF114, 560.

They are all the "GF" series though and the reason the two GF114's that you mention won't SLi is because they have different core counts, 336 Vs 384.

Yes I see, But as far as I know radeon cards are not like this, say a pictarin GPU can be crossfired with another pictarin GPU. Like 7850 and 7870?

Yes but they are Radeon cards which are made by a different company called ATi/AMD. That is why they are different and not the same.
