Hi im sure its ok to SLI these two coz only difference is the cooler right >?

Yes, they will be fine.

The FTW + has 4gb 's of memory and the FTW Signature 2 has 2 gb's of memory.
I thought to sli , both cards had to have the same amount of memory.
Please correct me if I'm wrong.

Edit : Maybe I read that wrong .

The FTW comes in a 2gb and 4gb model.

They don't have to be the same - with a 4gb card, the memory will be limited down to whatever the other other card is.

But, I'd imagine the OP's using 2gb cards for a question like this.

Im sure they have to be same vram

No they don't. If they have different amounts of VRAM they will collectively use the lower amount. eg. if there is a 2GB card and a 4GB card, the SLI setup will only be able to utilize 2GB of VRAM overall. It will, however, still work.

Can I mix and match graphics cards with different sizes of memory?
No. For example, an XXXGT 512MB cannot be paired with a XXXGT 1GB in an SLI configuration.

Should be fine as long as they have the same amount of VRAM though. I think the only difference is the cooler and possibly the backplate (if you have the FTW+ edition).

Once the card memory density are the same then you will be fine.
