Windows 8 Exclusive Features


Fast Boot

Instant OS Login

ASUS has released new hardware and software designs to shorten system boot-up time to two-seconds* for a smoother user experience that removes annoying delays under Windows 8, and even previous versions of Windows. Faster system boot and restart means Windows starts quicker and higher efficiency - no more waiting around.


ASUS Boot Setting

Multi-Startup Options

Thanks to ASUS Windows 8 hardware optimization, ASUS Boot Setting provides better flexibility in customizing your PCs startup process. You can enter the BIOS directly with one click through a user-friendly interface, and quickly select your preferred system boot up method: either get to the OS in seconds or opt for regular boot up. Whatever your choice, settings are saved and persistent, with no need to choose every time you power on.

"Ultimate Cool!" Thermal Solution


Thermal Armor

Total Airflow-Boosting Heat Dissipation

New generation TUF Thermal Armor kicks cooling up a notch with dual integrated Turbo Engine fans. This enhances the original TUF thermal design, helping direct heat away from MOS area components and out the case via the rear I/O section. Special heat pipes propel dissipation from critical components and make sure temps stay low across the board. The Thermal Armor also provides modders and LAN party goers an extra-cool dress up option to show off their creativity and dedication to performance.

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 one individually. The Thermal Radar automatically calculates ideal fan speeds based on different parameters selected by users for each component, keeping everything cooler and longer lasting.

5 out of 5 eggsGreat board!!

Pros: Everything about thus board is top notch! Great middle of the road board price wise. Great military themed colors.

Cons: Overclocking was a little more involved than overclocking my 2500k but I figured it out.

4 out of 5 eggsit worked

Pros: was easy to add to my case and it worked fairly well
been running it at our business and I have now bought one for myself.

A lot of options for the experienced overclocker and such...but documentation light on learning what it all does..

Cons: 1- the sata cables were half l shaped and half not...cost me a drive when transporting it to the new location as the case has the drive ends pointing to the case side...a slight jostle broke the sata piece off the drive killing it and the cable. Been nicer to have most L shaped on one side.

2- the backplate is not cut properly and cannot be used. It fits perfectly except for the audio. So I had to decide to cut the audio part out or just not use it at all. Really lame. They must have changed the audio spacing or something and never updated the backplate.

3- the two proprietary fans scare me as replacing them will be a super big hassle. Almost feel like I have to buy them from asus immediately, just in case.

4- the front usb 3.0 connection is incredibly loose. Just touching the cable and it pops out. Not sure if it is the case cable or the connector that has the issue. But my second cable I bought does the same thing.

Other Thoughts: seems okay, lets hope it works for years to come.

Pros: Excellent build quality with nice overall layout. Fit in an Antec 900 with i7-3930k overclocked to 4.0ghz. Awesome bios functionality.

Cons: No front USB 3.0 support

5 out of 5 eggsVery solid LGA2011 board...

Pros: For the most part you expect the absolute best when dropping for an LGA 2011 board. This board (being 3 years old) has stood up pretty well. Sure, flashing the bios right out of the box is a PITA - but ASUS though about that in advance. You really can't beat it for the price.

Cons: The ASUS software is wonky as always. but that will always be true.

4 out of 5 eggsASUS Sabertooth X79 LGA 2011 Intel X79 SATA 6Gb/s USB 3.0 ATX Intel Motherboard

Pros: This board is awesome! all the bells and whistles. Great bios! Great cooling. overclocking is crazy easy. ive been a asus fan for about 10 years now and never had a problem with any board. this one takes the cake for the best one Ive bought. Great buy!

Cons: Only reason I couldn't give this board a 5 egger is the chip set cooler fan sits right behind the #1 pci-e slot so if you have a rather big video card like I do the card sits right on top of the fan. Other then that A++

1 out of 5 eggsworks great..til u have to RMA it

Pros: with proper cooling and no oc'ing i got the cpu to 4ghz on some games. hyperduo does speed up hdd with ssd as cache like wonders. decent motherboard..just wish they stop building them in china..seems all tech goes to hell soon as they move to china

Cons: but after 14 months of started to die..multiple red lights on the motherboard, ram barely showed up even when full to 64gig.the sata ports started to die(i tried multiple hd and ssd brands..showed up in bios..but load an os and it died). i rma'd it followed instructions and now they say i sent in motherboard with different serial than what i rma least they could give me an updated rma to track it.

Other Thoughts: i clean the pc every 6 months with air compressor..i've been doing it for decades with my pc problems ever. i use hepa filtering on all my pc cooling gear but still need to blow it out cause sometimes dust do get thru.

Manufacturer Response:


I apologize for the issues you are having with the motherboard. Please contact me through email regarding this case as I may have a solution to this matter. Within the contents of the email, please make sure to include your RMA number. 3555970.

1 out of 5 eggsvery disappointing

Pros: Can support 64 GB ram and 2 way SLI, and LGA 2011 sockets. Latest BIOS makes overclocking a breeze.

Cons: ASUS USA support is horrific. At least one of the agents I talked to was obviously using google translate or a similar program.
Very poor quality. The board I bought has had multiple problems. The CPU sensor was faulty upon purchase, as were 5 of 8 ram slots. Now, a year later, the USB controller has become increasingly unreliable to the point where my system is unusable. Lastly, the PCI-E tabs are extremely fragile, and snap off far too easily.

Manufacturer Response:


I am sorry that you are having issues with the motherboard. At your earliest convenience, please send me an email regarding this case. Within the email, please provide the serial number of the motherboard. 3552849

3 out of 5 eggsAsus Customer support

Pros: The motherboard is a great. It is super fast, but will soon be obsolete. My system is 1.5 years old and my system has failed. But the M/B ended up being good. This is a followup review. Turns out it was a pulsing 5vds in the power supply that was causing the issue.

Cons: ASUS America Customer support needs some serious revamping. It is the worst experience I have ever had with a company....EVER. It is no wonder EVGA is coming out so strong, with their warranties and superfast customer service, ASUS better wakle up.

Other Thoughts: Asus customer support/ technical support though I had a bad M/B too so I wont fault them there. It is their RMA process. They deliberately have their RMA system set up to be as difficult as possible. I decided to do an advanced RMA by having a hold put on my CC for $360.00 . Their form had to be FAXED to them, because they are living in the1990's. 4 days later they reply to me stating they could not read my CC number on lousy form. They couldn't call me or take the CC over the phone. Or accept an electronic signature on the form they sent to me, that was made for an electronic signature. Four more days pass before I get information saying that my RMA has been processed again (on a Thursday). By now my customer is angry at me for the delay. I paid extra to get my board overnighted, and what do they do instead of sending out on Thursday it takes them another 2 days to ship it. It was send on Monday, and I got it Tuesday. 3 weeks for an advanced RMA is Ridiculous.

Manufacturer Response:


Thank you for providing your valuable feedback. Here at ASUS we believe that providing a positive experience through customer support is our number one priority; I am very sorry this was not the case in this circumstance. Moreover, I will make sure this case is notated for quality assurance purposes. Hopefully, due to your helpful comments, this sort of experience is not repeated for future customers. That said, if you have any questions or need help with the motherboard, I am here to help. I can be reached through email. 3556004.

Thank you,

5 out of 5 eggsGreat Board At Great Price

Pros: purchased this board as a open box item was a bit Leary but the price was right so i took a chance. I'm glad i went for it the board came well packaged with all its accessories I used the one button bios flash feature which is awesome and it posted right away with my new intel 4930k . It has a full featured and easy to get around UEFI bios and with a little research on the net (as i was coming from using amd cpu and boards for many years ) I was able to achieve a stable 4.7 overclock on my cpu on a custom watercooling loop with this board . its been running rock stable with 64 gigs of Gskill memory so far at 1866 I know that's alot of memory but i am using 32 gigs of it as a ram cache for my 2 Samsung evo 1tb drives that i have set up in raid 0 man goodbye long load times in games. this system will serve me well for a few years to come

Cons: none so far

Other Thoughts: its built well has many great features and in my own experience has been very stable thanks newegg

Pros: Great motherboard and works fine. Very powerful and would recommend to anyone looking to build a powerful pc.

Cons: Haven't found any yet

Other Thoughts: I got a motherboard with a defective ram slot, only 3 out of 4 ram sticks work. I called up and requested a RMA and everything went fine. Still haven't gotten my replacement, I went for the program where you give your credit card and they sent you the motherboard first. That was back in December 2013 and its March 2014 now

Manufacturer Response:


At your earliest convenience, please contact me through email to discuss this case further. Within the email, make sure to include the RMA number. 3556114.
