PCIe 3.0 Support

PCI Express® 3.0

PCI Express® 3.0 (PCIe 3.0) is the latest PCI Express bus standard with improved encoding schemes that provide twice the performance of current PCIe 2.0. Total bandwidth for a x16 link reaches a maximum of 32GB/s, double the 16GB/s of PCIe 2.0 (in x16 mode). As such, PCIe 3.0 provides users unprecedented data speeds, combined with the convenience and seamless transition offered by complete backward compatibility with PCIe 1.0 and PCIe 2.0 devices. PCIe 3.0 will become a must-have feature for users who wish to improve and optimize graphic performance, as well as have the latest technology available to them.

TUF Cooling

CeraM!X - Heatsink Coating Tech.

Larger Area for Heat Dissipation with The Revolutionary Ceramics-Coating Technology
Innovative ceramics effectively conducts heat away from the system. It replaces traditional anti-oxidant to dissipate heat better with its microscopic irregular surface and enlarged area. Better cooling leads to overall improvement in system stability.


TUF Thermal Radar

Real Time Temp Detection and Heat Removal 
The TUF Thermal Radar monitors temps in critical parts of the motherboard in real time, automatically adjusting fan speeds to make sure the system maintains high stability without overheating. It consists of multiple sensors for various components on the motherboard, giving users the ability to monitor each area, while increasing options for fan control housed inside the chassis. The Thermal Radar automatically calculates ideal fan speeds based on different parameters selected by users for each component, keeping everything cooler and longer lasting.

I've built 5-6 machines and this has been my favorite. Paired with a an AMD fx-8350, Asus HD7770-2GD5, Samsung 840SSD, Phanteks Heatsink.It's a monster. Board is very sturdy and feels beefy. Overclocks easily. Awesome warranty. The color scheme (tan) matches my case better tan the other (green)sabertooth. I love the board features. The "Mem OK" button saved me during install because my memory even though it's 1600mhz can only be recognized at first by any board as 1333 and has to be manually ent ... ered into the bios. I had one small problem. The installation disc was faulty and can't be read in any computer. I downloaded everything from the internet I needed, but it would be nice to have. Considering this board costs twice what I paid for other boards I was surprised. I contacted Tech support and the guy told me to go buy one from their parts and accessories site. First, it's a defective part. I shouldn't have to buy one, and second, there isn't one offered for the Gen3 board on the site.. This is the first time Asus has ever failed me in any way, but still this is a fail. I run a clinical laboratory and this is not the way I treat any of my customers. So if my board fails and I call, am I going to be told to "Go Buy another Board" ? More >

I upgraded my old motherboard to this and I'm blown away by the quality of this motherboard. I have been using this motherboard for a few days now and it's been running without any issues. This motherboard is so well designed and the bios is easy to work with thanks to the UEFI technology. Overclocking with this motherboard is super easy and I was able to get my old CPU (1090T) from 3.2Ghz to 4Ghz with no trouble at all. Just change the multiplier in the bios and you are all set. The SABERTOOTH ... 990FX GEN3 has nice heatsinks that keep the VRMs nice and cool. It comes with AI suite that can auto-tune your settings for your optimal performance but I don't recommend using it because it can cause random crashes. This is the only AMD motherabord that supports PCIe 3.0 which is a huge plus. Future GPUs such as the GTX7xx or HD8xxx will run great on PCIe 3.0! The motherboard comes with four DDR3 DIMM (up to 32GB of ram) slots supporting dual channel memory up to DDR3 1866MHz. I have my ram overclocked to 2133Mhz on this board and it handles it like a beast. There are also a ton of PCIe x16 slots available for both Crossfire and SLI multi GPU. The chipset allows you to utilize two full PCIe x16 graphics cards which is crazy fast. Or you can run four graphics cars at PCIe x8 and still get crazy results. This chipset also includes native support for SATA 6Gb/s which can be great if you have a lot of SSDs in your system like I do. The Asus Sabertooh 990FX/Gen3 motherboard is extremely well designed and it's awesome to look at. Everything is spread out enough that you have enough room to work with. Updating the bios for this motherboard is a piece of cake. You simply go into the bios and it will automatically load the file from your hard-drive/USB and you are done. ASUS has done a fantastic job of creating an amazing motherboard and the new 9-Series AMD chipsets is crazy fast. The bios is extremely well designed and the manual that comes with the motherboard can provide useful information on how to use it. There are two modes in the bios, easy and advanced. The easy mode is great if you need to constantly change boot devices and do basic things but I don't recommend using it for overclocking. The advanced mode on the other hand requires a much better system knowledge and has a ton of options that can be overwhelming at first, but give it time and you'll see how nice it is. It has everything that you could possibly want in a bios. Pros: -PCIe 3.0x -USB 3.0 -UEFI Bios -A ton of SATAIII ports -Super Easy to Overclock -SLI/Crossfire capabilities -Good VRM cooling -Sexy color scheme -8+2 VRM Phase Cons: -None Overall, I highly recommend this motherboard to anyone who is looking to get the best AMD motherboard on the market. I'm currently running my brand new FX8350 at 4.8Ghz without a hassle thanks to this motherboard. If you plan on upgrading to Steamroller when it's released, then this is the motherboard to get!

The product is exactly what is required for my processing needs. It arrived with all functions operational, and no shipping/packing issues. Pros: 1) Clean and easy to follow information specific to the board. 2) All components operational, bus speed is as defined, no off-drilled anchor points, no difficulty in installing add-ons (memory, video, etc.) 3) TPM header operational as expected, and functioning perfectly. 4) Those items not replaced on/with the motherboard (power supply, video, memory ... (initially) worked without issue. 5) USP 3.0 and USB 3.0 Boost operates at rated speed and w/o issue. Cons: 1) Software products provided (ASUS board management software) is not user friendly for multiple profile environments. 2) ASUS TPM Infenion software difficult and cumbersome when compared to native Win7 Ultimate TPM initialization and configuration. Not intuitive or well described. Overall I rate this board very high for environments which are less than optimum as is my case. My environment suffers from heat extremes (~70 - 95F) depending on season. Heat dissipation is second to none, and the hardened components are perfect for my operation. One thing, not related to the mobo, was at least one software product failed to operate properly: NetGear USB Printer Control. This product did not know how to deal with USB 3.0 spec; and triggered BSOD under specific circumstances. After removal; all was well. More >
