Will these cards run in SLI?

[TJ1122]

Hello, recently I received an AlienWare Aurora R4 as a birthday present, as well as an GIGABYTE NVIDIA GeForce GTX 560 Ti 1 GB GDDR5 video card. I was wondering if it would be possible to run the card I received as a gift with the card in the AlienWare in SLI.

The specs on my AlienWare are as follows:
Intel Core i7-3930K (Six Core, 12MB Cache) Overclocked up to 3.9Ghz
16GB Quad Channel DDR3 at 1600MHz
2TB RAID 0 (2x 1TB SATA 6Gb/s) 7,200RPM
1.25GB GDDR5 NVIDIA GeForce GTX 560 Ti

The graphics card in the AlienWare computer is a 1.25GB GDDR5 NVIDIA GeForce GTX 560 Ti, and I was wondering if it will run in SLI with my GeForce GTX 560 Ti 1 GB. After doing a google search of the 1.25 GB brand, I couldn't find it, so I'm assuming it's just something exclusive to AlienWare. I'm very much a tech noob... This was all a gift though, so I wasn't able to do much research before purchasing.

Hello & Welcome.

Download GPU-Z and take a snapshot & upload it here.

I think you better not to, because 1.25GB of Vram is what 560 ti 448 core should have. So it's not the same 560 ti...

Damn, you must have been good this year.

I think you have a special OEM card, that is still a 560 ti.

Well for SLI the brands dont matter. (Gigabyte vs your OEM)
But your right, the RAM might matter. I dont know myself, but I did find this:

"I've put together dozens of SLI systems over several generations of nVidia cards and rarely had issues SLIing cards of the same model regardless of brand, clock speeds, etc. couple of times had to flash both cards with the same firmware but thats usually an exception. "

I think it would probably work, just try it.

No, like the guy above said it's the 448 core that's why i asked for a snapshot.

Brands don't matter but specs do.

But your right, the RAM might matter. I dont know myself, but I did find this:

From SLI/CF FAQ;
But what about the memory? Can you SLI 7800GTX 256MB with it's 512MB version ?
For Nvidia cards,the general answer is no.

"Another misconception is that the GeForce 7800 GTX (256MB) graphics cards and the GeForce 78000 GTX 512 graphics cards can be paired together. Since these graphics cards use different GPUs, they unfortunately CAN'T be paired together. Always refer the Learn More or Build sections of SLIZone."
So,you generally can't pair a 7800GTX 256 with 7800GTX 512 or GTX 460 768MB with its 1GB version unless you use some 3rd party applications(which isn't recommended).
However,if you manage to run these cards in SLI,then the model,with higher amount of RAM,will reduce it's RAM to match the other card..

The core counts have to match, so if the OEM 560Ti has a different core count to the Gigabyte retail one they won't SLi.

Nvidia also states that you cannot sli two cards if they have a different amount of vram. As already stated by ilystaml, you cannot sli a gtx 460 1GB with a gtx 460 768MB.
