I used this motherboard to build a 5 TB server. Its been running for a few weeks now without any problems. I want to order another real soon for my own personal computer.

Happy with this board so far. Quite stable, good drivers.

Using this motherboard for a super encoding computer. I didn't need a strong graphic card for this and had issue with 2 graphic cards in pci-e x8 v1 and v2. Somtimes it was booting, and sometimes not. Very hard to pinpoint the issue, I had to call the supermicro support. The motherboard apparently only fully accept the recent graphic cards in pci-e x8 v3. So be careful with this.

Also note that this board when booting makes many bips, one for each installed  cards or hardware linked to it (it is not said in the documentation, and I thought it was bios bips signaling errors... But no, those bips are not boot system errors.

The only one bip telling that everything is in order makes its noise when windows is loading only, so a long time after.

Note that you have different version of this motherboard. Some coming with additional feature such as 2 different Sata Controlers. Mine only came with one. But it's fine.

For higher speed i suggest to use a separate Raid Card. A model fully compatible is the LSI 9270 8i. Using this will allow you to hardware raid your configuration, and will save some CPU use. I didn't use the integrated intel raid manager, but it's only software so I don't really recommand is.

Nice stable economic board. Boots pretty fast and bios is simple. Only issue I have with it is the usb ports on the back panel. I have over 14 usb devices (mixture of 2.0 and 3.0) and if I have all of them plugged in to the usb ports on the back the board will freeze and require a reset. I have all the latest drivers installed so thats not the issue. There are other usb problems that i have noticed but I will not list them all out here. Just be aware that those back panel usb ports can be problematic. The only solution i have found to the usb freezing problem is to use usb headers. I can plug a bunch of devices into the usb 2.0 header ports and the board will not freeze. Other than the usb issues I think its great.

Notice: You will not get mounting hardware(risers) with this package so be sure you have at least 6, but to be safe 9 M-3 Riser screws and M-3 screws to put into the risers. These generally will come with the motherboard but I purchased a package myself here on Amazon that worked well. This is normal for any motherboard purchase.

This is a very well constructed motherboard, sturdy and made of military grade products. I have been running it since just before Christmas 12/20/12 and have not had an issue.

The onboard code diagnostics is invaluable, I might of had to recheck the whole motherboard over and waste hours troubleshooting due to an imporperly secured RAM, but the codes allowed me to narrow down the area that was causing the motherboard to not boot. Saves much stress and headache. The XMP profile for my G.Skill memory was in the BioS and was extremely easy to activate as well as totally stable.

The onboard OC Genie button is a safe and conservative overclock for new enthusiasts that gives around 4.2 GHZ on an I7 at near stock voltage, if you are new to overclocking a CPU this will give good added performance without reducing the life of the expensive CPU. Just be sure to monitor the temperature and voltage with a free program like Core Temp in addition to the BIOS monitoring software.

Package comes with a detailed menu and a quick glance overclocking chart. It also includes case stickers and comes with stickers over each component of the motherboard making this a great motherboard for first time PC builders.

I put hours of time in reasearching Z77 motherboards and price to performance wise this one is near the top offering features near ASUS price points with ASUS quality by shorting some lesser little used features like eSATA and extra USB ports. Note this only comes with 4 USB 3, and 4 SATA 6 g/bs interfaces. Two of the interfaces will be on the CPU controller, these are the ones you will want to use for hard drives. The other two SATA 6 are on a Marvell controller which tends to have a little lesser speed compared to the integrated Intel ports.

All overclocking and FPS comparision charts has this neck and neck and sometimes beating the other Z77 mid range boards in its class like the ASUS Pro and Extreme6 boards, however I will note almost all the mid-range boards performed within the margin of error making the Z77 a very good layout overall.

The one area in which this board is outstanding is power management, easily beating out the ASUS Pro that has 12 phases with its 8+2+1 design. This board also includes hookups for a voltage meature so you can measure your voltage realtime with precision. It includes the wires to conect to a voltage reader(sold seperate).

For veteran overclockers, both the Windows BiOS and traditional BiOS are well suited to the task. I have found with my model both the voltage and speed are spot on. The dual BiOS boot allows for recovery from a bad clock very simply, but due note when upgrading your BiOS it will update both BiOS slots so be sure to use the Tool in the bios to create a USB backup.

I have not come into any problems with this board as of yet but will update if I do, however I am very happy with this product and got it at a great price $142 before rebate. At this price point it beat out Extreme6 handily and even with the $180 sale on the ASUS Pro I still do not regret it. If on a budget you may want to look at the Extreme6 as it is a very solid board, and if you want the spend a bit more the Pro is also a good board, but watch for issues with the onboard wireless and ASUS's slow decline of customer support.

If you have any specific questions feel free to ask below. The amount of research I put into this board and the Z77 line is staggering.

Great mobo. paired it with a Fx8350 runs super smooth and fast. Was built into a brand new build, had no issues with the mobo at all. Sitting inside of Corsair 750D fit great. Mobo's on the little heavy side but np. Was kind of nervous reading some reviews about their unlucky doa stories or just the mobo had some issues, but mine was super healthy 13lb fat baby. Asus is known to make quality superior motherboards especially on their higher end. There are soo many usb 3.0 outlets and 2.0. What i like most is the QCode reader, if theres anything wrong going on with your pc or mobo it will throw a double digit code to ref' into it in your manual to see what exactly the issue is. And has tons of 4pin's for the fans.

This is an outstanding mobo. I really love it. The most powerful part of this mobo is the bios. Intel put a lot of effort into giving the user complete control over everything with helpful explanations accessed by  hovering the cursor. WARNING: You really have 'complete' control. Don't be surprised if you have to to back in and re-set the settings.

On the other hand, there is not as much room on this board for newer cards. I have to give up a USB 3.0 card to fit in a sound card with my video card, because my video card blocks two slots.

Other than that, great board!

The Gigabyte UD3 has been excellent so far. The stock settings for the motherboard are pretty weak, but it's extremely customizable. I've personally found that the included profiles (including memory profiles) don't work well at all, and cause the PC to be unstable, but as long as you know what you're doing, they give you free reign to alter each and every setting individually when set to Manual.

The board runs cool and supports all of the hottest features today such as USB 3.0 (with internal header) SLI and CFX, Sata 6.0Gbs, and PCI-E x2.1 (not x3.0).

Used this motherboard in my first build and could not be happier. It's running Windows 10 Pro using Intel's Skylake i7-6700 processor @ 3.9 GHz (not OC'd) with 32GB of Crucial's Ballistix Elite DDR4 memory at the stock 2400 MHz, an EVGA GTX 950, finished with Samsungs 950 Pro M.2 SSD. I had zero technical issues building this machine.

If you don't need all the bells and whistles other Z170 boards come with then go with the PC MATE but REMEMBER TO UPDATE THE BIOS TO THE LATEST REVISION! This board comes with a revision older than the earliest one on it's support page and you might experience memory issues until updating.

I purchased this Sabertooth 990FX R2.0 on February 6th 2013...almost exactly 3 years ago. For 3 years I used this motherboard nearly 24/7 and I still haven't had a single issue with it. I got a crappy FX-8350, which happens I suppose, but this board made the best of it and allowed a decent stable overclock. It still runs great, but I decided to give the system to my little brother as a graduation present since I had been wanting to do a new build anyway. I'll miss "The Ultimate Force" logo that comes up during POST, and I'll miss looking inside my case at this great, great board, but it never let me down...not once, so at least I can walk away happy with the knowledge that I got my money's worth. If I could, I would give this 6/5 stars. If you're going for AM3+ and you want something rock solid with more overclocking and power settings than you could ever imagine, buy this board....because you definitely won't regret it. I know I don't.

Great motherboard but the description needs to say socket LGA2011-V3.  This will only work w/ the V3 4th gen CPUs. It will not work with the i7-4930K.  Good thing I had another project that required one of those.  It is compatible with the i7 5820K.

Also note that it has a USB 3.0 header which is not compatible w/ USB 2.0 cable sets so you will have to purchase one of those if you want front panel USB.

All that said, if you need reliable I/O, this board will do the trick.  The POST is a true test so, w/ the DDR-4 ECC RAM, it takes a little time to start up. Once the POST is complete, it boots in about 7 seconds.  Total time is about 30 seconds from the time I push the power button. The 256G RAM limit is crazy!  I only put 32G in there and it meets the needs of the job I am asking it to do. I am not doing graphics intensive stuff so can't comment but it does have dual 16x slots. I have dual GTX 780tis in another Supermicro and the graphics are great on it so I would think this would be as good.

This is a 5 star motherboard but I am only giving 4 stars because of the misleading socket description. To be fair, Supermicro does not have this info on their spec sheet either so, Amazon really isn't at fault here.

great bios another well done job by Asus, works well with tower my only problem is my usb 3.0 cable won't stay put in its socket it keeps wiggling and falling out anyone else have this problem or is it just mine ?

Current build:
* EVGA Z97 Stinger Wi-Fi Motherboard
* Intel 4790k 4.0GHz CPU
* MSI GeForce GTX 980 4GB GPU
* Kingston HyperX 16GB DDR3
* Rosewell 750W PSU
* Samsung 850 Pro SSD
* Thermaltake Core V1 Case

This little motherboard is wonderful! I am amazed at all of the features packed into this little form-factor. My GPU dwarfs this little guy! Performance is stellar! Windows 8.1 boots in less than 7 sec from power switch to desktop! The Wi-Fi is pretty good, but the installation of the leads connecting them from the daughter-board to the case is a bit tedious, but quite doable (be patient).

Only complaint (minus 1 star) is an issue I have with the "Intel 9 Series Chipset" driver in Windows 8.1 - For some reason, the software won't install the newest SATA III certified driver from Intel because it thinks windows' driver is better (which it is... sorta). The Microsoft driver is automatically installed after the first boot from fresh install. The Microsoft driver appears to work at the full SATA III speeds, however the event log fills up with Event 153 messages related to my SSD. Benchmarks show SATA III speeds (~545Mb/sec) with the MS driver. However, when I manually install the Intel drivers, the event errors goes away (hooray!). Unfortunately the drive speeds reverts back to SATA II and even the Samsung software confirms the lack of SATA III on the interface. I blame Intel's drivers and not EVGA for this issue - I am still on a hunt for better drivers, but at least the event error is gone and I really don't notice any performance issues.

Beyond that, this board has performed wonderfully after a week of marathon LAN party action! I think that is a good burn-in test - so far so very very good!

Before buying this board, I did a Lot of research trying to find an affordable AM3+ mobo that had all the good features (like sata3) AND also sported usb 3.0 headers for the front usb 3.0 connectors on my case. Mind you, many more Expensive boards boast USB 3.0 support, but most of them only have usb 3.0 ports at the BACK only. If you have a chassis that has usb 3.0 front connectors, you would not be able to use them on Most of these other mobos.

This mobo just does the trick for me. Its AFFORDABLE, has a usb 3.0 header, sata3, a graphical interface bios (very easy to navigate and has mouse support), and the back has only the necessary modern connectors for a nice clean look (no serial ports, lol)

I am very happy with this product and Highly recommend it.

Asus, as usual, hasn't gone with the flow, and built a very capable motherboard!

This was my only choice, as I need ECC support for disk integrity in the server, and even the original BIOS release fully supports unbuffered ECC.

The additional USB 3.0 socket offers 4 full-speed ports, which are fully supported by recent Linux and BSD distros, as well as Windows 8.x.

The size of this board is actually SMALLER than Micro ATX, width wise, without sacrificing the expansion slots, so I'd almost want to call this Expanded ITX (the width is ITX spec, and the length is Micro ATX). Case mounting points are exactly as MicroATX, so no worries.

The AM1 only offers 4 PCIe lanes free (all internal components are on 4 dedicated PCIe lanes, which are independent from the slots), but that is absolutely sufficient should I need to add a SAS controller or a 10Gb/s NIC. The PCIe 16X slot is only wired for 4X cards max. Adding a 4X card will essentially turn off the two 1X slots, or a 2X slot in the 16X position will still leave the 1X open for business.

My only concern was the Realtek 8111GR LAN controller, as I have previously had major speed slowdowns with older Realtek chips, but this is quite solid. It is NOT BUFFERED, so plan to have CPU activity on LAN work as part of the package.

For a low-power BSD server, this is absolutely ideal, as thus far I have no need to add additional hardware, at least until 10Gb wireless reaches the consumer market!

This latest one will be being built soon, with an AMD Athlon 5350 quad-core APU, Crucial ECC unbuffered memory, a Kingspec 16GB SSD, and handle my MediaSonic Probox drive enclosures, including SATA replication, over the USB 3 interfaces. Overall, in-system should be a cool 35-40W, with the only real heat producers external of the machine.

Gigabyte will soon release the C1037U version of this motherboard but meanwhile this is a fantastic deal for a motherboard to run OpenELEC, Linux Mint or even a Windows 7 nettop if you don't have a lot of expectations around compute power. I did not try Windows 8.1 but I've heard it performs much better than Windows 7 on this platform.

The Celeron C1007U CPU in this motherboard is about 50% faster than the C847 and about 3x faster than the Atom. It comes with an Intel HD GPU embedded in the chip that flawlessly plays 1080p video in both Windows and Linux. Since it's Intel, there is very good driver support in Linux. The GPU also supports bitstreaming of HD audio in both Windows 7 and Linux thanks to the GPU drivers again.

My experience with the motherboard is building small form factor home theater PCs for use with OpenELEC. So far I've built four of these with 4GB RAM and an SSD. I've installed them in the Travla C137 and IWill HT-80 mini-ITX cases. Thanks to the motherboard having 2 USB headers, I can hook up the front panel USB and install an internal USB IR receiver on these boards. There's also enough SATA ports for an optical drive, SSD for the operating system and a large storage drive for media. Of all the Celeron embedded motherboards I've tried, the fan on this one is by far the quietest owing to it being the largest available. It's also easily replaceable. I have been powering these with a picoPSU-90 and 60W AC adapter. Maximum power usage only measures around 30W with a Kill-a-Watt meter.

In OpenELEC, the interface is very snappy and videos are smooth. In Windows, general interactions are just a hair slower than what you'd get from a desktop Celeron like the G1610. Videos are also very smooth in Windows using WMP or WMC.

If you're looking to build a very small form factor HTPC or even a small nettop, especially to run something like Linux Mint, Peppermint OS or Ubuntu, it's really hard to beat this motherboard. Gigabyte will soon be releasing a C1037U version, including one with a passive heatsink, so it might be worth waiting for that but if you can't, you can't go wrong with this motherboard.

I've used a few of these motherboards now and recently had to install a wireless PCI card. When I installed the PCI card the machine would not boot with the default BIOS settings. It just hung before the BIOS splash screen. I had to change a couple of settings to get it to work:

Peripherals > Init Display First: change to IGFX
Peripherals > Internal Graphics: change to Enabled

I think it was detecting something in the PCI slot and by default trying to use that for graphics instead of the on-board.

This is the first desktop motherboard I've been really happy with for a long time.  Paired with an i7-4790S (BX80646I74790S) and two Kingston 16GB kits (HX318C10FK2), this is totally stable and very fast.  The UEFI BIOS isn't buggy and POST time is fast.  Running Fedora 20, a full compile of the ZFS tree takes 3 minutes - on my 3-yr-old AMD desktop (with the same disks) it was taking 30 minutes.  Xen runs well and all the hardware seems to function as expected (running triple head on the built-in GPU, plus one AMD PCIe head).  Make sure you have a new enough power supply (a good excuse to go modular if you're upgrading).
