I purchased this Mainboard with Building a reasonable upper middle range computer in mind without busting out too much $$ for it.

This Mainboard is Awesome, More of a Mainboard than I expected for the money, it performs perfectly, overclocks and runs smooth with no system hang ups and has great bells and whistles like the WIFI and Bluetooth that at first I figured ya ya ok neat I'll never use em ..... well I now have it configured to update my Ipad,Itouch,Smart phone and Mac book Pro to auto transfer files to and from them and control my sound system in the house .... it is a private well behaved Cloud system.

Ok so I installed the Intel extreme - i7-3960X LGA2011 Processor along with 16 Gig of Corsair Vengeance DDR3 memory and running it on Windows 7 Ultimate all this went into a Cooler Master 932 HAF full tower case being powered by the Corsair HX1050 Power Supply and the Processor is being cooled with a Corsair H100 Liquid cooler.

Cons? becareful once you start a build like this it will be hard to stop.

I built recently a system using this motherboard. I haven't had issues with the dimms like many other people do, but the issues I currently have are regarding the USB 3.0 ports. This board uses the Asmedia 1042 and VL810 chipsets for it's USB 3.0 ports, right now both chipsets have many problems, a good example is that when reading data through the USB 3.0 it works perfectly fine. The problem comes when you want to write data (transfering data to a External Hard Drive or HDD Dock using USB 3.0), basically after minutes the PC hangs and the USB 3.0 devices get undetected. After searching a lot it seems that it is a common problem with the Asmedia 1042.

If you plan on using your USB 3.0 ports to transfer data, then either search for a motherboard that doesn't have the asmedia chipset or consider going to lga 1155 with the Z77 that has usb 3.0 chipset done by intel.

I'm pretty disappointed that the USB 3.0 ports of my x58 motherboard work better than the ones on this x79 motherboard.

With luck Asus will release updates of the firmware of the chipset and drivers so the port get to actually work as intended. The board was released on November of 2011 and Asus hasn't released a fix yet...

Dear Valued Customer,

We apologize for the issue you had with the motherboard.

This motherboard is capable of USB 3.0 Turbo and UASP modes which can significantly improve transfer rates. Can you try using AI Suite and set USB 3.0 Boost to Normal mode to see if the external drive / lock continues to hang on transferring data? We haven't had heard reports of problems of the Asmedia 1042 controller. Can you email me about them at Thank you.

Having read a number of other reviews where the user had various problems with this MOBO I was a bit apprehensive in purchasing the board. I feared the worst. I expected many problems with the BIOS. My fears were unwarranted. The MOBO POSTed the very first attempt. Granted, I was not trying to install a raid array of any kind. If I had perhaps I would have had problems. My approach with this build was to install a single HDD and SSD and then in the future add additional HHDs with a raid array.

After installing the MOBO I had read from other reviews the first thing I needed to do was to update the BIOS. I knew this needed to be done using the white USB connector on the back of the MOBO, and then pressing and holding the flash BIOS switch on the MOBO for 3 seconds (until the blue light flashed). The one thing the ASUS instructions failed to mention is that you needed power to the MOBO to accomplish the BIOS update. Perhaps this is one of those obvious things that everyone is supposed to know. The initial attempt at flashing the BIOS did not work (nothing happened). Then when the power supply was connected and turned on it worked perfectly. After this one small hiccup everything worked fine.

I chose not to use the applications and drivers provided on the CD that shipped with the ASUS MOBO. Instead I had downloaded and saved to a flash drive all the latest applications and drivers from the ASUS web site. These all installed very easily. At the end of the day, everything worked fine.

It has only been a day since the build. There is a lot to learn and play with. I used the automatic over-clock function of the ASUS MOBO and it increased the CPU speed from 3.2 to 3.9. I populated the MOBO with 32 GB of Corsair Vengeance 1600 Mhz memory modules.

I just purchased 2x P9X79 Deluxe motherboards after having a perfect experience with the P9X79 board. As always I check the compatible hardware list from Asus and follow their recommendation stringently, therefore I’ve never had a bad experience until now. I’ve built dozens of computers over the years and have never had this much trouble with one product.

So I dropped an Intel Core I7 4820K 3.7Ghz LGA2011 CPU into both boards and set them up in a case ready to boot. On both machines I get nothing, no boot, no error codes, nothing and a red CPU LED. After researching Asus support site on how to use the Flash BIOS feature, a big reason I bought these boards, I do what I’ve done dozens of times before with my other board, download the latest BIOS file and use the Flash BIOS to install. Usually this fixes all problems and you up and going in minutes.

This time so such luck. What makes this a bad experience is that the support from Asus appears to be nonexistent. So I’ve turned to other resources like Tom’s Hardware and the HardForum, where I read post after post going back as far as 2011 of others who have had the same experience with this board. They can’t get a response from Asus and they are left with having to purchase a new BIOS chip, crack open the motherboard, which voids the warranty and replace the ROM to get a new BIOS installed. A customer should never have to do this on a new board.

I’m miffed in a serious way at the moment, so I apologize in advance if I’m coming across too harshly, but after spending $1200.00 for top of the line hardware, I expect top of line support and can’t get it.
