rjohnson11 Finally got it to work. Here are the results:
pharma57 On the side you should try concBandwidthTest.exe 1 (use "1" instead of "0").
bolts4brekfast Even though I don't fully understand the purpose of this test.. lol Here are my results: My specs are in signature.
boylerya Still waiting to see significant benches where the bandwidth is tested for both PCI-E 2.0 and 3.0 in games or any other program like Solidworks that will saturate the bandwidth well. Only benches ive seen showed a 1 to 3 fps difference in high demanding games, but I dont think that was testing SLI which is prob where it will make a real difference.
linuxrouterYour bandwidth numbers look good overall and about what I see with my 3930K and 4930K processors and NVIDIA Kepler GPUs. Depending on which result you were looking at, the 24K value could be the sum of bandwidth for multiple cards or the sum of the H->D and D->H bandwidth values.
error-id10tGuys, I don't understand this and what it's meant to show? I do however see that my 670 SLI is way lower than what others report. Also, why is my 2nd card faster when they're clocked the same (exactly).

doogkieWas messing around in my bios and noticed it saying my top titan was running at pci-e 3.0 x4, So i found this thread and I ran the test and I am getting some horrible numbers. The bottom card is running 8x, but its getting bad numbers too I think. My mobo is a MSI Mpower Max, any idea? Getting an average of 6059 for device 0 and 3035 for device 1
