Yeah as the topic is saying, I got issue with my PCIE 3.0 ports, they are saying my grafic cards are running at x8 1.1
I should first mention that I had these issues for a while, and I also updated all drivers to the latest versions, but still same issues. I got the 1,4 bios version for the motherboard and the nvidia V344.65 that was released today.

I tried to change it in bios from auto to gen 3 on the PCIE-ports, but still same results.
I made a post earlier about that SLI running slow in WoW and 3Dmark Firestrike. Maybe this is the source to the issue due to the ports running at 1.1 and not 3.0?

Also, in both WoW and 3Dmark Firestrike, I get much higher FPS and results with just one grafic card activated, when I go into SLI the results drop like a rock..
The weird thing about SLI though, that it seems to work okay in games like Diablo 3 ROS and 3Dmark11.
I have my grafic cards in the recommended PCIE-ports, 1 and 4.


Here is a screenshot how it looks like in GPU-z:




Is this a known issue and is there any upcoming fix to this? Feels really bad I can't use my grafic cards to their fullest potential..


My whole computer setup:
Intel i7 5820K | MSI X99S Gaming 9 AC (bios 1.3) | SLI MSI GTX 980 Gaming 4GB | Samsung 850 Pro 512 GB | WD Red 4TB | G.Skill Ripjaws DDR4 3000MHz 4x4GB | EVGA SuperNOVA P2 1000W | Noctua NH-U14S PnP | Fractal Design Define XL R2 | 5 Noctua NF-A14 PWM 140mm fans | Windows 7 Pro 64 bit

It shows 1.1 when idle, how about click the question mark and run the test? Should go up to 3.0.

Yes, run the Render Test to see fullest potential of your graphic card.

yes run a render test! when a card idles it will revert to 1.1 from 3.0 as its under no load

Did, still same results in SLI:



The second card reverts back to v1.1.

its probably because the render test doesn't handle or don't support SLI well and second card become back to idle

run something else apps., bench or games who support SLI well then check their modes
Enable sli load balancing if needs from nvidia control panel to check SLI utilization

Seems to work the correct way when I start a game, but still got issues with WoW and 3Dmark firestrike. My results with SLI is far worse then with just one single card activated. Anyone know why?
I get more FPS from WoW with one card then two, and I get much higher score in 3Dmark firestrike with just one card..
