Maximus V Formula Mother PCIE 16X running at X4

Hi
I buy maximus v Formula and build system at first using ATI6950 Graphics card. It works fine for sometimes then one day nothing. Generally I take it as graphics card down. So I order a GTX 780. After adding that card still no graphics. After installing reinstalling OS+Lots of studying Bios I find that its detected by BIOS but running at X8.

After that by loading optimized setting I can make the system stable but my main X16 running at X4 and 2nd PCIE slot running at X1.

I flash bios and load 1802 which is the latest for this motherboard.

System is running stable and firestrike score is 8195 and Graphic score 9122 and I am playing metro last night at all setting high except physx off. I do bechmark it and get avg 44FPS.

So all things considered I should be happy without full bus support. But I am planning to SLI and I am not getting any peace that system is not running at its full ability.

I even planning to buy a Gigabyte GA-Z77X-UD5H but it also seems have some near kind of problem with graphics card. It seems funny but low end MB like G1.Sniper M3 does not have much problem(at least not finding in net)

If there is any solution will be really appreciate(Not sending back system.)

System config:
Core I7 3770k 4.2 Ghz
Maximus V Formula
Transcens 4X4GB aXeRam DDR3 2133
GTX 780
Monitor resolution 2560x1440
Thermaltake tough power 1275W
All things are 3 weeks old and GTX 780 is only 1 week old

Hi
Its a long time I make this post. Updating one thing. I just remove my processor and re-attach it and now my link speed increase from X4 to X8. I was just going through posts of same problem. Someone suggest that due to make the cpu cooler screw tighter this prob may happen as motherboard pin does not connect ok. So thought give it a try. Now is the result as it is not still X16 so again asking advice on it. Let me know if u have any. I am so afraid that I don't think I can again open the CPU n do it again as if this x8 speed gone. Know funny. Thanks

Have you made any changes to your BIOS, and especially the section in the main menu that effects the PCIe lanes?

I would suggest you try Gen3 for the lane you have fitted your card.

I have the same problem. Did you figure out what was wrong?
