Windows 7: Thinking about going SLI

Thinking about going SLI

I was thinking about adding another GeForce GTX 560 Ti, but i was wondering does it have to be the exact same model? Or will any GTX 560 Ti work, and will using an overclocked card with a stock card break the SLI setup?

Edit: also, how easy is it to go SLI, just turn off the PC, add the card, connect the SLI ribbon and it'll work?

Yes, just shutdown and connect it.
Once you boot into windows, you'll need to enable SLI in the Nvidia control Panel.
You can even set it up as a Single card GPU, with the other as a dedicated Phys-X card if so choose.



I think you'd be best to match cards that have the same default clocks though.
Im fairly certain they both should be running at the same speeds.

Hopefully others will know for certain on this.

As far as the brand of the card, it shouldnt matter. Although Id try to keep them the same just so it looks better

You can mix cards from different manufacturers. They must have the same amount of RAM, but they can have different clock frequencies. (I presume that the SLI pair will default to the clocks of the slower card.)

It is better to get the same type card ram clock speeds

when ever doing a sli or crossfire set up the slower gpu will be the pace maker for the faster card you want equal card strength so you can get smooth performance

Bought the card and new case today, bought the case because I looked in my current tower and noticed very little clearance between the PS and the second of two PCIx16 slots needed for SLI, I was looking for any excuse to upgrade my case anway.

A bit late in the day, but a lot of questions are covered in nVidia's SLI FAQ:
