It specifies 4gb cards. 2 gb cards will throw an error and say incompatible, as it isn't the 4gb cards. It probably had something to do with the expanded memory and this corrects it.

No new Bios for 2GB version? or plans?

Is there something wrong with the 2GB version?  Does it need an updated BIOS?

The 2GB model is fine and this BIOS would break the 2gb version.

Actually there is something wrong with the 2GB version as well. I just purchased a second 960, MSI 2GB Twin Frozr and NADA. This is the second time this has happened to me with EVGA cards, first was with a 970 setup, EVGA and Asus. What's the deal guys, all the other manufacturers cards work fine together. Beyond that, I like your products a lot...but seeing as I can't run SLI! this is frustrating. 

Hey, thanks for absolutely NOTHING ty_ger07. Yay! My name is on the interwebs, I had nothing to add to the conversation! Weeeee!

I'm going to do sli soon and I would like to confirm if my card already using this bios?
 

My card is a 04G-P4-3967-KR. I can't find a sli fix for it. :-(

Man, I completely forgot about this post. I was able to get mine fixed through completely different means. Just out of curiosity, what is your motherboard?
 
Mine was a evga x58 ftw3 . Apparantly mine couldn't handle the amount of video ram it was being given automatically. I can't remember the exact setting name, I can check on it when I get back from work though. If you can't wait I'd recommend actually calling EVGA support. They were actually super helpful, as they were the ones that pretty much instantly resolved my problem for me with one little bios setting.

It will only update whichever firmware is selected. There is no need to flash both, unless you really want to for whatever reason. Since you can only use one at any one time, it doesn't matter which version is on the other chip you aren't currently using.
