Can I SLI a 2GB card with a 3GB card?

post #1 of 4
Thread Starter 
Hello everyone,
I have an EVGA 2GB stock clocked 660 Ti right now (rest of system specs in signature). Newegg came out with a deal today for an Asus 660 Ti 3GB version (slightly overclocked, with free Batman Arkham Origins) for $210 after coupon code and $30 rebate:

and I'm very tempted to buy. My question is will I be able to SLI them together despite the different PCB manufacturers and different amounts of VRAM?
I'm fairly sure that if it does work I'll only be getting 2GB total, which is fine, as long as it does work, since I'm gaming at 1080P 120Hz.

Any info would be much appreciated, cheers! thumb.gif

Yep I believe you can SLI them, but as you mentioned you will only be able to make use of a 2gb frame buffer (the VRAM of the lower-capacity card)

edit: another point of interest; you may need to try to even out the core clock and memory clock on both cards. I know some people using different manufacturer cards for SLI and Xfire setups have mentioned that they did this, but I'm not sure if it's actually a necessity...

as far as i'm aware, yes you can as they're the same chip just one has more memory chip's compared to the other 660ti.
