Hello i have a question about the SLI

I use a GTX 680/4gb Gainward Phantom and now i want also upgrade to SLI with an another GTX680 but with 2gb.
But my question is simple can i run the same cards with different ram without any problems??
Or maybe one of you have it already and can tell me does it works fine?
Can you tell what is you experience??

This used to be in the NVIDIA SLI Faq. Weird how I don't see it anymore.

Can I mix and match graphics cards with different sizes of memory?

When purchasing a second graphics card, you should try to match the memory size so that you are ensured full value and performance from your purchase. However, while it is not recommended, NVIDIA does offer the flexibility to run graphics cards with different sized memory by using CoolBits. Using CoolBits (value set to 18), you can force both of the cards to use the lower of the two memory sizes and operate them together in SLI mode. When dissimilar memory sizes are enabled to work together using CoolBits, the effective memory size for each card becomes the smaller of the memory sizes.
