I hope this is right thread.
 
I can't get PCIE 3.0 enabled on my PC without it causing major latency, audio, visual, distortions. I upgraded from a 3930k to a 4930k thinking I needed a PCIE 3.0 CPU to get it to work correctly.
Specs :
Asus P9X79-E WS Motherboard BIOS 1301
4930k                  CPU
2x EVGA 780's     GPU
PCIE is set to AUTO in bios, which gives me PCIE 2.0 in windows, if I set it to GEN 3, I get all kinds of problems, my question is, is this simply a Nvidia driver issue? I have also tried the GEN 3 Hack tool which didn't work, I dont know what else to do, any ideas?

Yes, I tried that, I even did it thru admin/cmd line, doesnt change to 3.0 in auto, and even changing it to gen3 before or after force enable gen3, still have problems if pc runs gen 3. Ive reinstalled windows, installed only the GPUs and nothing else, still 3.0 doesnt work for me.

I do have a sound card in one of the slots, but when I reinstalled windows at first I just had only the 2 gtx 780's in place, in the x16 slots, best I can do to test it is, ill take out everything except 1 780 and try it in different slots to see if I can run 1 card in pcie 3.0. I'll let you know my results.
 

I am on the latest BIOS, the 2nd one Asus has had for this motherboard for Ivy Bridge  BIOS (1301 for P9X79-E WS released to public  2013/10/17)
I am also on the latest Nvidia drivers 331.58 WHQL
I've done the most basic stuff I can think of, I ran the PC with just 1 780 in it, with it in different PCIE slots, x16, and x8 slots, I've tried each 780. I think its some kind of driver issue, Nvidia or Asus, also im on all the latest chipset, usb, lan, drivers etc.....
I can take some screenshots of my PC in both GEN 2 and GEN 3, but if I set Gen 3 in bios, the audio stutters and the video, like in Valley benchmark will freeze up every few seconds. I've googled this problem alot but its been hard to #1 find anyone using this motherboard with pcie 3.0 working, or #2 not really sure what the latest news for x79 boards and pcie 3.0, so just asking here.

I am on the correct BIOS..... you looked up the P9X79 WS, im on the P9X79-E WS

I needed to disable SLI before I ran 660force-enable-gen3.exe re-boot then enable SLI before the NVIDIA Control Panel Showed Gen3.

 
^^^^This.

A note about your i7-4930k you should not have to use 660force-enable-gen3.exe on this CPU, I did not need it on my i7-4960X and X79 Dark.

I still need it with my 4930K.  I think it has more to do with nvidia's drivers still being only "pcie 3.0 ready" than with Intel.
