I do have 8GB.
2x2GB of DDR3 1600 (PC10700) and 2x2GB of DDR3 (PC12800). Both sets G.Skill Ripjaws.
For the longest time I tried to blame the mis-matched RAM on every issue that I've had.
But after running countless hours of Memtest, Prime95, and others, I can't find an issue with it.

Thanks EliteReplay for the screen shot!
What are your clock speeds on the cards?
And what program is that your using to monitor your fps?

Well actually i run everything on stock, im not a huge fan of overclocking videocards...

i would run everything at high, maybe drop shadows to medium. You dont have video ram for ultra, not even close. for bf3 you want to have a video card with 3gb video memory. im using 2x6870's on 120hz screen.. my goal is close to 120fps as possible. i run everything on high 16x, but no anti aliasing, i turn off motion blur. bf3 runs pretty good most of the time, but all depends on the drivers im using.

I just set mine to HD 6870 voltage just because I don't know too much about OCing graphics cards.
Seems like as soon as I get good and comfortable with one card, I end up buying new ones.
What I meant, is do you have the pumps ran in series.
Like having the coolant going from one pump to a rad, then to the other pump, then the other rad, and then back to the first pump.
The only reason I asked is because I've seen some of the Corsair H50 mods where people throw a second rad or reservoir into the loop.

The 2 units are completely separate and in stock form.
Only thing that's different on them from when they come out of the box is I lapped them and they are cable tied because the bracket wouldn't fit.

1GB Vram is enough for 1080 on ultra, Just on the karkand maps you will start to hit the vram limit since they are still very poorly optimized and a lot of stuff gets loaded into memory that you will never see.

These cards are very poor at AA since they have a low texture rate, But the higher you overclock the better they will get.
My 3Dmark 11 gfx score is 8751 so if your close to that you should be able to run every thing ultra as well. And if it doesn't work then it has to be a driver issue.

Some things that may or may not be relivent on my set up is I also have a SSD which BF3 is installed on. (made massive difference in load times, Maps load in under 10 secs)

And my PCI-E is overclocked to 102mhz. (made 70 points difference in 3d mark 11 but overclocking it too high can give negative results and corrupt your hdd.)

Both my cards are in 16X slots and my CPU is overclocked to 4.6ghz.
