I have sli on gtx 560 non ti
one is superclocked and one is not since the boxingday sail was one per customer. here is my speck

i5 2500k
corsair tx850m
Gigabyte ga z68ud3h b3
dual 560s from Gigabyte
kingston hyperX 1600Mhz

when ever i want to play BF3, it crash at the loading screen
I've tried all the drivers including the beta
Its not only battlefield. i have problem with League of legends and i will try running SC2
I believe that 850w is enough for dual 560s and i think that one superclocked card is the main problem.
if you have any solution for this ill be very thankful. if you have the same problem feel free to solve this with me.
thank you very much

remove one of the 560's
Reboot into safe mode
uninstall all the drivers
uninstall the card from the device manager
reboot
let the system "rediscover" the single card
install the latest release, not beta, driver
reboot again and run furmark and heaven against it.

good or bad...

now try the games...

results?

add the second card in SLI and try again w/ furmark and heaven

then games.

Go slow and think about each step.

underclock the super clocked one to the others clock speed.

Your problem could be cause by the overclocked card. When you link two cards in SLI both cards will be set to run at the same clock speed. So the slower card might be up-clocked by the drivers to match the faster card and may have become unstable in the process. You'll have to check that what clock speed each card is actually running. I would also disable SLI to make sure each card works properly on it's own.

Have I seen you post that before? You weren't right then either by the way.

I had a similar problem with metro 2033 and a few other games with my 480 sli set up turns out it was the antivirus program not letting the exe run.. turn off antivirus and firewall and try it just for giggles.. :o

SLi is much pickier than CF-X.
the cards do not necessarily need to be the exact same but have to be closer in specs alot of times.
you have a few things that be going wrong for you.
1 - Gigabyte GPU's are known to have the most issues
2- different speed cards

in the nVidia control panel is SLI enabled.?

yes it is
