Low Benchmark Results with 560 TI SLI

First off thanks for any help!

I am running a 560 TI SLI setup with a 850W power supply and a AMD FX-4170 OC CPU. I have been getting 3DMark scores that are lower than I am seeing other people reporting. This is also occurring in Unigine Valley benchmarking program as well.

This has been a problem since I have tried to get the cards working together. They are both 560 TI's but one is a Zoltac and the other is stock. I have verified using the SLI is working using the Nvidia SLI indicator.

Things I have tried:
Updating GPU / CPU drivers.
Toggling "No Snoop" attribute in PCI-E settings within BIOS.
Updated motherboard BIOS.
Turning off power saving mode for GPU.
Installed Win 7 hot fix for AMD BullDozer CPUs (this gave a slight improvement).
OCed stock 560 TI to match clock settings of the Zoltac card.

My Results:

Thanks again!

Biostar ta990fxe right..?

well, white slot for pcie 16x, red slot for pcie 4x..

Do you use white and red pcie slot to run your 2x560Ti in sli mode..?

if yes, that's why you have a lower benchmark than the other...
because you run sli in pcie 16x and pcie 4x..

while 2 other use pcie 16x and pcie 16x to running their sli 560Ti cards..
