Hi fellas,
First time Nvidia SLI'er here. (long time ATI/AMD user)

I'm a bit puzzled on what why results are within 3DMark 11...

SLI Disabled


SLI Enabled


When running the benchmark in SLI..
I noticed a lot of freezing throughout the process.
When it wasn't frozen, the fps were higher than when running the test on a single card.

Anyone have any ideas/insight on the matter ?

Here are my Specs:
I7 3770K @ 4.6
Asus Maximus V Extreme
2x GTX680
16GB Corsair Vengeance
Corsair TX750 PSU

Did you enable SLI in the Nvidia control pannel?,did you make sure all the 6/8pin power connectors are firmly connected?,did you make sure the SLI bridge is firmly connected?

Thanks for your response,

Yes, I enabled SLI within the control panel;


The bridge is indeed properly connected as well..


Odd... Physics score bumped up a bit when enabled, though graphics plunged.

Edit:
Cooling is not bad at all.
It rarely goes above 65C and idles in the high 30's

Progress...

Running 3DMark after a clean restart shows much improvement in SLI!


There may have been some sort of background process affecting the scores before.

I'll continue to monitor and see if I can suck a bit more juice of of these components ;)

Thanks fellas!
