Awesome board
By bob
I put this board in my computer about 6 months ago. My computer is a 2u that sits as a thick client in a server rack. There are several reasons I chose this board, other than price.1) Solid capacitors (caps are the leading cause of boards bricking over time. "cross-tops" or non-solid capacitors can split or even leak 'goo' when they heat up. It isn't that they aren't rated for their designated uF, they just aren't built for longevity. Solid caps are.)2) 8+4 phased VRM with pulse modulation (the cleaner the current is to the CPU, the more efficient it is. Pulse modulation uses switching to deliver current much like high end PSUs. With the additional {8+4} transistors/chokes/phases the load is spread out more, letting it run cooler and making it safe (virtually unheard of) from overloading the CPU. These are features that make this board inherently reliable.)3) The second SATAIII controller {ASMedia ASM1061}supports hot swap at full 6.0 speed.The Intel controller only supports 2 of the four SATAIII connectors {SATA3_0 and SATA3_1 for RAID}. It's the same with all cougar and panther point chipsets (p67, h67, z68, z77, x79 etc. anything with a numeric designator of 65 and up)Speaking of SATAIII:TRIM is NOT supported in RAID 0 in anything but a 75, 77 or 79 series chipset at present (Also you have to have the Intel Rapid Storage Tech version 11.6 or newer which is upgradable on Intel's download site. Without it, you can run 'fsutil behavior query', and it will still say zero, but enabled, and 'on' are two different things in this case). If you want to RAID 0 a pair of SSDs, and have that performance last, you have to get the TRIM working. This board meets the requirements to do that.4) a back up ghost BIOS5) Layout (in a 2u chassis you only have so much vertical room, and cooling is critical as you can't use tall CPU coolers, multiple 120mm fans etc. Also the PCIe has to be done via a riser card. With this board's layout I was able to fit everything into the case, to include the cooling for an i-series running at 4.2, a second NIC for the console interface, and pretty beefy graphics card supplementing the on-chip Intel HD4000 for the eyefinity.)What I was able to get out of this board: 4.5Gigs on the CPU, tuned it down to 4.2, sometimes it hits 4.3 (but that's the board doing its own thing), 2000 MHz out of the RAM (from 16 gigs of 2133 RAM), and a Gig read and write off of the primary SSD RAID 0 array. To say that this board is as fast as the best components is an understatement. While I can't comment about gaming (I didn't build it for that) I can say that it is lightning fast, crunches big data without breaking a sweat, and sits on the edge as well or better than any computer I have plugged into the network (I used this for my computer...the one I use everyday, and have found myself dipping into the servers less and less. It is actually changing the way I work).I've built a couple AsRock units for myself, and used one as the board in a system I designed that we offer to the public. I don't want to say anything negative about Asus, or Gigabyte but It seems like I am always having to tweak something down the road with these boards (an option you don't really have if you are building the unit to ship to customers). Biostar and Foxxconn are just awful for a list of reasons as long as my arm, MSI should stick to video cards ("military grade"?), never used an EVGA so I can't comment there. Zotac got their big niche with the ITX boards, but don't put out anything in the ATX sizes that really do anything noteworthy. Intel makes a very sound, reliable board, but they always seem to be lacking a feature or two that I can get cheaper in a different board.In short, if I had to recommend a board for gaming, I'd probably say Asus...I've built a ton of those, and have had great results. But in a gaming rig you want to tweak stuff every once in a while.....it's part of the allure. I'm sure this ASRock board would game very well. The thing is that all of that tech they develop for gamers ends up in workstations eventually (kinda like stuff NASA came up with 10 years ago is available at the mall today)....and this is one of those crossover boards (although I doubt that's what they intended). You have all of the speed you could want but with the reliability, and simplicity (you don't have to tweak it every once in a while) you need in a daily driver.

By SCOTT A VIETH
I've been using this board for about two months now and have no complaints. Obviously first and foremost, it does its job quite well, and is running my Core i7-2700K Sandy Bridge CPU without any issues (although it's made for Ivy Bridge, 3rd-Generation CPUs).POSITIVES* The number of USB3 ports is excellent, and the fact that the on-board USB3 ports are driven by separate chipsets (two on-board, two with an ASMedia chipset) means less congestion when you're pushing all of the ports at once. Plus, the additional headers making for a total of six USB3 ports is a nice overall number.* The SATA2 and SATA3 ports are nicely organized, but they're definitely made for a case with bottom-mounting hard drives. The case I bought actually had a special mount at the bottom of the case for a 2.5" SSD or hard drive, and with how this board is built, it's perfect.* The tools that come with the board work well, and aren't overly intrusive. XFast Turbo USB does help with USB speeds (although not as much as they claim), the XFast LAN tool provides great insight on the LAN activity of the computer, and the tuner allows for basic overclocking on the fly. I don't know if this is a CPU, or if it's the board, but the heat factor goes way up even on a small overclock, so like some other reviewers have said, I don't think I'd use this board for hardcore overclocking, but if you need a small boost, maybe 10%, this would do ok even with air-cooling.NEGATIVES* The SATA port that's shared with the external SATA3 port isn't clearly marked on the board, so you have to really watch which one you're using if you want to still use the eSATA port.* Using the kind of cooler you'd want to use, in my case, the Cooler Master Hyper212 Evo, really puts the crunch on the RAM ports. If you're going to use all four RAM slots with a big-time cooler, you may want to go with low profile RAM to avoid any issues on that front. I used Corsair Vengeance RAM, and due to the large heat sink, it essentially cuts it down from 4 slots to 2 "usable" ones.Overall, the negatives don't take it down beyond a full 5-star rating for me. They're annoyances, and in any motherboard this price, if you're hunting for perfection, you'll find one or two places where they compromised, but for the price point, this can run a good gaming rig, or be a very good daily driver, no doubt.
7 of 8 people found the following review helpful.My favorite motherboard ever
By Robert Contreras
I could go on for pages about how awesome this motherboard is but I'll do my best to keep it brief.Pros:1.)Price is amazing2.)UEFI BIOS is probably the coolest thing to ever happen to motherboards (a graphical BIOS that works out of the box and supports mouse AND keyboard)3.)Digital Error Display - I don't know what this is officially called, the motherboard has a small 2 digit LCD display that gives codes that can be referenced in the motherboard manual. This way if you have an error with the RAM for example, the motherboard can tell you specifically the RAM is causing the issue and save a boat load of time.4.)Power and Reset buttons that are built on to the motherboard - makes testing components in your build very quick and easy, no case needed to turn on the computer5.)Good looking color Scheme6.)Includes SATA 6 cables for your hard drives7.)Crossfire/SLI support with 2 PCI EXPRESS 3.0 slots.Cons:I haven't found any. I tried my build with an MSI motherboard that costs about $60 more and had memory issues, I used this board and it booted on the first try, solid like a rock. This is THE Z77 chipset board that most people should get.I'm not saying there aren't other nice boards on this chipset, but for the price there is not a better one.
