Question 1

Is this board already flashed with bios that supports the i7 4th gen cpus? I have never flashed a board before so i wanted to buy one that is already setup.

Thanks

Accepted Answer

This motherboard may or may not be flashed with a bios that will work with Ivy Bridge-E chips.  It would depend on the manufacture date.  The bios flash process is simple, and you will probably want to do it anyway to get the latest bios.   Download the bios from ASUS support website, rename is to P9X79LE.cap, copy the file to a USB stick that has been formatted to FAT32, insert the USB stick into the designated USB slot on the motherboard, connect your power supply's ATX power connector to the motherboard, and press the flashback bios button.  It was simple and took about 6 minutes.  I mounted mine in the case first and connected only the ATX power cord to it.  After I flashed the bios, I then added the CPU and finished building up the board.

Question 2

Is the motherboard compatible Windows 7?

Accepted Answer

Indeed it is. I had no problems- remember though, to install Windows 7, you must adjust the BIOS settings and set the boot type from UEFI to Legacy for the most problem-free Windows 7 installation.

Question 3

Will this be able to support the i5 core?

Accepted Answer

Jon W,
Long story short: no this will not work with an i5 processor from Intel. Read below for more specifics

I recently purchased this motherboard and have been delighted with it ease of build and performance. However, it has the LGA 2011 socket for the CPU which I believe is only compatable with the intel i7 line of processors. The Intel i5 processors will require the use of a motherboard with the LGA 1150/1155 socket type depending on the model you choose. 
I would recommend picking out a specific processor before matching it with the motherboard you want to use. This will simplify your build.  Good luck and hope this steers you down the right path!

Question 4

I installed a Gigabyte GTX 760 4 GB card on onto this motherboard and I can't Get video.  Is there a step that I am missing?  The Card worked fine in another build.  I am a noob.

Accepted Answer

Can you get to the BIOS screen? Does the PCIe status light on the motherboard light up? Did you install the card in the top-most PCIe slot?
It's very easy to not insert them all the way. Make sure the pins on the card and on the port are aligned, the card is straight (perpendicular to the motherboard), and push it gently into the top-most PCIe port (the blue one closest to the RAM slots and processor). Push until you hear or feel the click of the flexible piece on the end of the port that keeps your card in place.
Make sure you connect additional power to the slots on top of the card, and that your PSU can supply this power. Turn your computer on and watch the PCIe status light. It might be obstructed by your card if it has a large cooler, but you should be able to see if the light is on (refer to the manual for where the PCIe status light is). If the light stays on, re-check that the card is inserted and gets enough power. If the light goes off after a few seconds and still there is no video, I would try different ports on the GPU.
If all of these fail, I'd get in touch with Asus support, since your card is known to be good it must be the motherboard.

Question 5

Does this have PCI Express 3.0?

Accepted Answer

Technically it is "PCIe 3.0 ready." So it yes it does, but you need to make sure the BIOS is up to date for proper support.

Question 6

would an intel i7 3930k be compatible with this just wondering cause it says something about the ivy bridge on this mobo?

Accepted Answer

Without looking at that CPU specifically, I can't say yes or no, but as long as it is an LGA 2011 socket type it should be compatible. I believe that the CPU you are referring to is indeed such a socket type, as well as the motherboard is, so no worries there. I would double-check against my word, though, as I'd hate to mislead you.

Question 7

Can this run 2 pci-e slots at x16? or does one go down to x8?

Accepted Answer

Yes, it has 3 slots PCIe 3.0 x 16. For single VGA would be at 16x (ASUS recomend to use the first blue slot), dual at 16x/16x (this would be your case, 2 first blue slots) and triple 16x/16x/8x(using thw white one).

Question 8

Is there an internal USB connector? I can't seem to find it, but in the specs it says something about it? Basically i want to use a H100i, and theres a cord that needs a USB connector in the motherboard? Will it work.

Thanks

Accepted Answer

I have looked at the H100i and it appears to me that it would definetly be compatable with the motherboard. However the Corsair link (for monitoring of the fluid temp displayed through a downloadable program on windows) I am not 100% on its compatability. The P9X79LE has 3 internal 10-1 pin USB 2.0 headers and one USB 3.0 20-1 pin header. So as long as the Corsair link cord connects to one of those it should be good to go.
Happy building,
Mike

Question 9

Why the move from the use of on board wifi on mother boards?

Accepted Answer

Because honestly you can get a USB wifi micro dongle for about 10 bux. By eliminating wifi on the motherboard it frees up from for better hardware else where on the board. As a gamer myself, I wouldn't use wifi on a desktop motherboard. It would be a waste. Plus hassling with the antenna is a nuisance when a USB dongle have no antennas yet still get great signal inside the house. I got an Asus USB dongle for 10 bux on newegg and it works better than my laptop built in wifi...

This motherboard is excellent, even without on board wifi. You won't be disappointed. If wifi is needed, a low cost dongle will suffice and if range is an issue, a cheap USB 2.0 extension will help that to raise it up.

Question 10

I just bought this motherboard along with the i7-3930k processor. I am looking for a great CPU cooling fan (preferably water cooled) that will fit this. I have read several reviews of fans and most said they will not fit a 2011 board. Can anyone point me in the direction of a good fan to use? Thanks in advance!

Accepted Answer

If you're talking about a CPU cooler, that should be more a function of your case size and shape. Most good coolers have mounts for various types of sockets. If you prefer liquid cooling, I personally went with a Corsair H100i to cool my 4820k with this board and a Cooler Master CM 690 III case. Just need to make sure you have enough clearance in your case to accommodate the radiator with fans. I would also recommend buying two of these: http://www.newegg.com/Product/Product.aspx?Item=N82E16835103192 to replace the existing fans on the H100i to help reduce noise (but again that was my personal preference. You may also want the no LED version).
