5 out of 5 eggsThis MotherBoard is a 5 star..

Pros: By UpGrading from XP-Proessional 32bit for two yrs. To Windows 7 Unlimited 32bit you loose the Nice CreativeLabs XFI SoundCard, No Drivers for this MotherBoard on Win 7 Ulmited, Stuck with High Def Sound Only.

Cons: I was Off by learning New TechStuff and up grade to a New Opperating Systm like Win 7, But after 8 months of 7 Unlimited 32 bit it fixed a lot of program issues like Speeding HHD,updating,USB ports,NetWorking.

Other Thoughts: After Recent Researching on this MotherBoards Potential, At it's current status running a Intel E8500 and Dominator DDR2 4GB 1066mhz. This Board runs at 1200 to 1600mhz at 16GB so it's Let's Do-it and found out this MotherBoard Run Best at 64bit, so Today it gets Win 7 Unlimited 64 bit, Maybe this will fix the soundcard issue??

5 out of 5 eggsSolid Board

Pros: Everything about this board is excellent and that's why I still have it. It's been running @ 4.2GHz with a QX9650 since 10/10/08 and never had a single issue. This is the board you want if you want to reach higher than the average overclocker.

Cons: none

Other Thoughts: It is true there are some of these out there that do have an issue with the thermal paste under the northbridge and southbridge heatsinks though I've never had the issue with the two that I have. Never had a NB or SB temp above 46c in the Antec 1200 though all fans were replaced with San Ace H1011's and A401's except for the 200mm big boy fans. Go buy an extreme gamer sound card and save yourself the hassle of dealing with the included just doesn't compare. The price seems a bit steep considering my P6X58D Premium i7 board was only $300 and I payed $270 for both boards back in 08. Price should be much lower in the i7, i5, and i3 era.

1 out of 5 eggsgood while it lasted

Pros: super solid design and functionality. awesome for high end users, overclockers, and other tech savvy ppl who would like to invest in one of the best mobos. but....

Cons: after a little over 1 year of use, it finally died. i was running vista 64 bit first. when windows 7 finally came out, i was one of the first to upgrade to windows 7. none of the drivers from the website installed. they all gave me error messages. while trying to see if vista drivers would work, my entire system went black as if the power went out. a full day of troubleshooting followed. i tried a different power supply, different cpu, memory, and video card. finally the problem turned out to be the mobo. requesting for an rma, asus tried to get a good chunk of cash out of me, saying that in order to process the rma, something else needs to be fixed and it would cost me over $100.

Other Thoughts: it was great when it lasted. as far as rma goes, similar experiences are shared by my family members and some friends who use asus products. generally they try to charge you for some random things you weren't expecting. and upgrading with windows 7 has been difficult and slow. maybe i'm just unlucky as during the last several months, i've experienced a lot of my asus products failing on me and not upgrading correctly, and it has left me a bitter taste in my mouth. i own 2 asus g1s laptops, 2 desktops and a few other systems that i built for some of my family members and they have a lot of asus products in them. i don't think i'll be buying any more asus things from now on.

Manufacturer Response:

Dear Valued Customer,

There is no charge associated with being issued an RMA, aside from customer induced damage. Maybe you were offered an advanced replacement RMA. One advanced replacement option we offer requires a temporary credit card authorization hold which will be removed upon receiving your defective motherboard. If you would like to pursue an RMA for this motherboard please contact me at and reference case number NE0299.

1 out of 5 eggsasus maximus 11 formula mother board

Pros: Not sure Yet

Cons: Cant find a power supplie to run the board

Other Thoughts: Cant find a power supplie 800 -850watts, to run the board, It needs to have the -5v white wire to fire the board up, The vid card needs the 800 watts, Help Please

Manufacturer Response:

Dear Valued Customer,

Try typing '800W power supply' into newegg's search field and make sure that the main connector for the power supply is 20+4 pin. Also, make sure that the power supply you purchase has at least as many 6-pin or 8-pin PCI express connectors as required to power on your video card.

Best regards,

ASUS Support Team

3 out of 5 eggsFast, but audio not compatible with Linux

Pros: If you want a virtual machine server, this motherboard is very good. Add a quad-core CPU and 16 GB RAM, and it can run four virtual machines easily, or up to seven 2 GB virtual machines without too much lag.

Cons: Creative Labs, which makes the SupremeFX sound card, does not support Linux. So if you want a high-end Linux desktop, don't get any motherboard with Creative Labs sound hardware. This m/b has it, which was a huge disappointment. This motherboard is not cheap, but it didn't work out for what I wanted.

Other Thoughts: I wish the Newegg reviews would have warned me that this motherboard's audio is not Linux compatible. I get to use it as a server though, so it's not all bad.

4 out of 5 eggsAnd then it died!

Pros: This motherboard is loaded with BIOS configuration features and has tons of hardware options and advancements. 8 SATA ports, 6-12 USB 2.0 ports, AI Overclocking and so on. Once setup, this motherboard has absolutely phenomenal performance. My boot time on Windows 7 64bit was 6 seconds!
My system build (detailed below) had no issues with cooling or air flow. The only BIOS setting I modified was to clock memory at DDR2 1200 (which I had installed, but whatever). The ASUS BIOS auto overclocked my CPU to 3.6Ghz (temps of 18-30C) with no voltage fluctuations or temperature spikes. My system hardware was running on this motherboard as was Windows 7 64bit without a single problem.

Cons: A) Don't install all the ASUS software since there is really no functionality beyond BIOS updating.

B) The Creative X-Fi... Not to beat a dead horse, just install the drivers. Creative offers nothing to the end user since after you register the card there is no software beyond the 30-day limited trial stuff that does not recognize the SupremeFX card.

I purchased this motherboard after reading all the reviews and understanding that there could be "issues".

Other Thoughts: Um, if I could boot the system I could swear the Silicon Image Sil5723 is really a Marvell SATA Controller.

After 3 months of ownership, while smashing on alliance my system blinked off. Literally. My system instantly lost all power and then fans ramped up and no POST. No boot sequence, just the hum of the fans. This motherboard is proverbially dead in the water. I am not very happy about it.

-Antec Nine Hundred
-Asus Maximus II Formula MB
-Intel E8400 Wolfdale C2D Processor
-4GB G.Skill DDR2 1200 (PC 9600) Memory
-2xWD RaptorX 150GB HDD's in RAID 0 (on Speeding HDD)
-Corsair CHCWH50 Water Cooler (CPU)
-HIS Radeon HD 4890 Video Card
-Corsair Modular 750W Power Supply
-LG CD/DVD Lightscribe Burner (SATA)

I will be starting the RMA process.

5 out of 5 eggsI'm Very Pleased

Pros: Specs:

Q9550 @ 4.02Ghz
FSB @ 1912Mhz
DDR2 @ 1261Mhz ( G. Skill 1200Mhz RAM )

These are the setting I were able to get stable. Almost six months now. Not bad !

Cons: None so far.

Other Thoughts: About the voltage settings. I played with them quit a bit, but I was never really happy with the results. System seemed a little off, I mean I can't put my finger on it. It just wasn't right. So I decieded to just set my ram voltage and the FSB to stable speed and that was it. : )

4 out of 5 eggsGreat, BUT!

Pros: Great board, a lot of extras, quality product.

Cons: This isn't the BOARDs fault, but if you're wanting to run windows 7-64 bit, think again. Setup/install disk is worthless. Not compatible with this OS. The AI---SixEngine---Probe II----you name it is not compatible with this OS. The best part, I can't even get the 64-bit drivers or apps to run after I downloaded them from the ASUS website. Oh, the best part, that really cool sound card that dose all kinds of stuff...........Nope. Creatives own software sees the card when you register but eveytime you open the console, it says it cant find a supported device!

Other Thoughts: I love this board and I love windows 7, but not together on this build!!! Headack after headack. I wish ASUS would get it together, or that I could talk to someone because I feel ripped of in a since.

Manufacturer Response:

Dear Valued Customer,

We apologize that you're having issues getting this board to work with Windows 7-64 bit. Please contact us at or 812-282-2787 and reference case number NE583913 so that we may get more details about your system configuration and assist you in resolving the issues.

5 out of 5 eggsExcellent mobo

Pros: I love this board! I like the plethora of options in the bios to play with. Not to mention the software that comes with it on DVD. I bought this in mid march and have had zero issues. Gamers rejoice and buy this board right away.

Cons: Eventually I will have to buy a new one once this is outdated.

Other Thoughts: If I wanted to build another gaming rig I would get this board for sure.
