Mixing models & Speeds in SLI

[Larnz]

Hi Guys,

I currently have a Gigabyte GTX680, it's a reference design/clk speed card as I purchased it when they first came out. I game at 2560x1440 and while the one 680 gets me by in most games at high settings things like tomb raider obviously required me to drop a few settings like tressfx and ssao etc to maintain 60ish fps.

Anyways, I want to pick up a second 680 but the only 680s avalible where I live now are all super overclock versions of the cards etc now.

Is there any issue if I SLI my ref gigabyte with something that has a faster clck/mem speed etc? I know that the faster card should slow down to match the ref card but does this cause any stability issues or any other bugbears to be aware of?

Thanks
Larnz

No issues whatsoever, I have done this (unintentionally) for years with many different cards, Nvidia and ATI alike. The only 'issue' you could really run into is if one card had more VRAM than the other, in which case you would be limited by the smaller number, as you probably have guessed.
