5.0 out of 5 starsAwesome board
By bob on November 2, 2012
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.Read more ›

5.0 out of 5 starsExcellent Value, Overclockable, All The Modern Ports
By SCOTT A VIETH on December 24, 2012
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.Read more ›

5.0 out of 5 starsMother of all gaming motherboards on a budget
By MO from NJ on February 28, 2013
Verified Purchase
I recently ordered this MB and built my first ever gaming rig after a long time. I've to give this motherboard 5 stars as it is built of high quality components and very easy to install. Only issue is that it doesn't come with onboard wireless chip but I still give it 5 stars because you pay half the price for this board compared to Asus or Gigabyte. I would definitely recommend this board for gamers who want to get the juice out of your OC'able processor.

My rig config.
This is the best overclockable processor to build a budget gaming system. Easily OC'ed to 4.2 Ghz without getting hot.

1.0 out of 5 starsWorks when it wants to.
By Gunslinger on December 2, 2015
Verified Purchase
This board is way too erratic. I've never had so much trouble with a PC build ever.

Right out of the box it refused to boot, and was showing a different error code each time. Returned it for another, which worked for a few weeks past warranty before it started having the same problems.

For no reason I can figure out, it will occasionally choose to go into a boot loop when I start it up. It will continue starting up and powering down over and over until I reset it (which doesn't always fix it on the first try).

Trying to navigate the error codes is pointless - they change each time it reboots, and I've tested the issues the codes supposedly report with no problems on other builds.

I'm not sure where the issue is, but its very prevalent in this mobo, I advise going with another board. Just look up asrock boot loop and see how many people have this issue - which is largely unresolved.
