According to GPU-Z,CPU-Z and the bios, The graphics card is running at PCIe3.0 x8 and not at PCIe 3.0 x16 even though the board is compatible, I have no sli or any other cards. Can you please explain to me why this is happening and what I can do to correct it?

http://www.intel.com/content/www/us/en/motherboards/des... , I Mounted it on the blue slot (the only PCI Expressx16 one). Why is the bios saying this? I paid like 500 dollars extra to get this ivy bridge setup as opposed to a sandy bridge, do you know why it is running at this speed? Is PCIe3.0x8 better than PCIe2.0x16? Will changing the motherboard,updating the bios or changing the graphics card make the card run at PCIe3.0x16? Also the bios says the card is running at 2.5 GT/s

nope can't find it, can only find the place where you enable usb ports, it is not even in the bios glossary, http://download.intel.com/support/motherboards/desktop/..., why do you say there is no difference between running at x8 and x16?

do not settle for x8/.
the difference in x8/ and x16/ is more minimal in SLi or CF-X set-ups
in single card mode, you are at a disadvantage in x8/.

alright I will be trying the bios update thing out next week.Also xtreme5, you were right at the start, the gtx 670 memory bandwidth is 192.2 GB/s, while the PCIe3.0 x8 is 476.8 GB/s (8 GT/s per lane * 8 lanes *7.45) http://en.wikipedia.org/wiki/Gigatransfer, so it seems i won't be losing anything other than a paper specification. By the way according to the nvidia control panel, my IRQ is 16 and my Bus speed is PCIe x16 Gen 3, what does that mean?

I had a similar issue with my 560ti on an MSI 890fxa. I noticed originally that my Hypertransport clock was running at 2400 and I remembered reading about the HT should stay around 2000 (AMD) and so I go to lower it and I just got that card so I'm running all the new games and I"m thinking to myself...this isn't much faster than the GTX 275 that I just got rid of...so I'm overclocking the hell out of it and not seeing much of anything. About 2 months later, I pull up GPU-Z and I notice where it says bus interface PCI-E 2.0 x 16 @ 2 1.0...at first I didnt really notice because I thought it meant that I'm that I"m using the 2 rev of PCI-E 16...but after looking at it for about 5 seconds my heart fell through my ass. I had been running that card for the last 2 months on a full PCI-E lane at 2x speed. Now I was seeing an improvement over the GTX 275 but not what I was expecting. I was kind of pissed that MSI would just downclock my PCI-E bus because I downclocked the HT bus. My solution was to go to BIOS and revert back to safe settings then save it and reboot. Then when my PCI-E showed @16 2.0 I went back to overclocking WITHOUT touching that HT bus speed. It was a major lesson I learned that day, so when I got my 670 the first thing I did was check that friggin PCI-E bus. I had never heard of that happening before and I wondered how many people were out there overclocking their cards and running on a limited bus that got set there by the system for fiddling with a small item in BIOS. Pisses me off to tell you the truth.
