By JJCEO #1 HALL OF FAMETOP 10 REVIEWER on March 9, 2012
I just built a new computer and this motherboard was one of my key choices. I have had good luck with ASUS motherboards as they are top quality and I love their new UEFI Graphic BIOS for set up and over clocking. This board has some very good features that I liked and that was why I selected it.

I needed a LGA2011 socket for the new 3930K six core Intel CPU and I wanted 8 DIMM slots. I am running 32 GB of memory in quad core at 1600 MHz. This board is designed with Thermal Armor heat dissipation and uses two on board fans to cool the North Bridge and South Bridge as well as the high end power control section. The entire board is manufactured with military grade components and carries a 5 year limited warranty. This board is ideal for the CPU I am using as the CPU can draw over 150 watts when overclocked.

One of the new features is a Thermal Radar system that continuously measures the temperatures at 12 critical areas of the motherboard and displays them in real time. The Thermal Radar calculates ideal fan speeds and it has seven fan connectors on the motherboard to control your fans. You can have the system control the fans or you can use the AI Suite II (Or BIOS) to set the fans manually where you can even program the temperature versus fan speed curve yourself.

The board features tunable power control for the CPU and DRAM and you can program the over or under voltage and current you desire for your set up.
Out of the box with no overclocking my computer build was rated by Windows 7 as:
Processor 7.8
Memory (RAM) 7.9
Graphics 7.9
Gaming Graphics 7.9
Primary Hard Drive 7.

The card worked great for about a year. It died and I had to call for an RMA. The process was a complete nightmare. 4 Calls - all over 45 minutes long asking the same troubleshooting questions as the first one. We had tested everything previously, and being asked to do the same thing again and again is slightly irritating. After sending it in, I received no communication until the card showed up in the mail. It was dead when it arrived again. I called up and asked for an explanation, they said they tried to repair it - it then failed the test, but after a few more attempts it worked. Apparently not! After that I am being told I have to RMA the product yet again, all on my own dime (after spending 400 on the board and another 40+ to ship it the first time) and will have no computer for well over a month. The product worked well, the service behind it was very subpar and I would not recommend it for anyone.

This board is amazing, nuf said... lol no it deserves a more in depth review. Been an Asus guy for half a decade now and have no intentions of changing that with this latest helping of awesome sauce. The Sabertooth X79 is the best X79 board that Asus offers at the moment. It out preforms the RIVE but a small amount but has higher quality parts, costs much less, and has a longer warranty. While the board cannot support 4x1 Crossfire/SLI it can do 2x2 Crossfire/SLI. I would not recommend using the third pci-e port as it is half speed.

While the board also does not have all of the features that the fully kitted RIVE does it also has some improvements and much of the same technology build into it. I have not attempted to overclock with it yet as I want to break it in first with some stock system usage but I have read it is a very stable OC platform. It supports up to 32 GB of ram and has quad channel ram support. The rear IO and chipset have their own dedicated fans that do their job well (CS is usually 1C). Easy to install and easy to install stuff onto like many of Asus other motherboards (q-connectors = pwn).

With military grade parts that are put through heavy testing before being installed you know that this board will last quite a long time and also be able to take the heat, literally, from overclocking.

8 DDR3 ram slots and 3 PCI slots are great. Although, I can never use the PCI slot 3 even if I wanted to because it sits too low and my PSU gets in the way. This board worked great for me for 11 months until a PCI slot went bad. This comes with a standard 3 year warrentee, but getting Asus to honor that is a big pain. They do everything they can to discourage you from shipping the item back to them. When they finally accepted to take mine back, it mysteriously got lost after delivery. I had to give them my tracking number of the package I sent them to prove they recieved it. After that, it was suddenly found, repaired, and shipped back. Although they did repair it for me, I feel like they were trying to get one over on me and that is the only reason I give 4/5 stars. I like the product, but I will not be dealing with Asus in the furture.
