  • newegg ASRock OMG (Online Management Guard) Fast, Easy and Free – ASRock OMG technology allows you to establish an internet curfew or restrict internet access at specified times. Administrators are able to schedule the starting and ending hours of internet access granted to other users. Normally, ISPs (Internet Service Provider) will charge for internet curfew service. The service controls “all” the PCs connected at home through network remotely but all the PCs in that network will be restricted to access the internet at pre-setup times. However, ASRock OMG is a free tool for controlling internet access of each single PC. Parents can easily control internet access through BIOS setup to protect their kids from using Internet at inappropriate time, and meanwhile, enjoy their own internet space.

5 out of 5 eggsEasy-peasy

Pros: I3 3720 and this MB are great. replaced an old MB and 775 dual core in two hours . Popped in a stick of corsair 1600mhz, 4GB laying around(windows 32 bit) and hooked up my OS SSD and let Windows 7 do its thing before I updated drivers. It ran great off the Intel graphics but I ended up putting in a 7750 AMD fan-less to pop up my score. Every thing runs cool.

Cons: None

Other Thoughts: Great upgrade for the price. Cheapest I've ever done.

4 out of 5 eggsNot Purchased through Newegg

Pros: Everything it is advertised to be, fits the purpose the build was intended for.

Cons: HD Audio Connector as was said in other reviews is too close to the X16 PCI slot making installation of my GPU almost impossible. The GPU is an old 550ti but it was intended to be used in the build, so I had to mod the shroud by cutting a notch out so it would seat up without ruining the the audio cable.
All in all, it was not a major issue to overcome, but should not have been an issue to begin with.

Other Thoughts: This board has some nice features for the price, and is in my opinion a good product for anyone looking to build a small form factor rig at a low cost.
I love Newegg, any buy 99% of my stuff from here, but this time it was at a lower price with less shipping fees elsewhere.

5 out of 5 eggsGreat board for great price

Pros: Lots of features: 7.1 CH HD Audio, SATA 6Gb/s, USB 3.0, PCIe 3.0 x16. Great price. Supported Crucial DDR3 1600 (PC3 12800) at 8-8-8-24 with easy BIOS setting change. The dark color and black connectors looks cool in a black case.

Cons: None.

Other Thoughts: Had to RMA first board because it would not POST. Not sure if it was the board or the processor. Newegg sent replacements for both and they worked perfect right out of the box the second time.

5 out of 5 eggsEnjoying this board

Pros: Lots of features
Relatively cheap
Features, features features.

Cons: A little expensive

Other Thoughts: ASRock boards have a tendancy to be vey thin thus flexible... plainly fragile. Doesn't really matter because they are bolted in a case, yet, make sure to connect the ram outside the board and to screw as many screws as possible.
I'm really loving this board, It's got all 3 display connectors, optical out, pcie 1 and 3, and alot of features for a mATX board. Currently being used as a NAS but will definitively be getting a second... This is my 3rd ASRock board and all three have been rock solid.

1 out of 5 eggsNo power! Bent CPU socket pins!

Pros: Going through NewEgg RMA process. Stay tuned........

Cons: I question the process on AsRock QOC checks on new motherboards. I have purchased four previous AsRock boards and never experienced this.

Other Thoughts: Awaiting the replacement of another new Asrock H77 board. My new system build is now on hold.

Manufacturer Response:

Dear ASRock Customer

We sincerely apologize for any inconvenience this may have caused you.
For the power issue, please check the power supply and grounding issue causing the problem.
The CPU socket is covered with the protection cap to avoid damage the pins and should not be removed until installing a CPU. In addition, the CPU socket pins on the mainboard are fragile and need to be handling with carefully.
If you have any technical questions or warranty issues please contact our Tech Support at We can assist you shortly.

Thank you

4 out of 5 eggsGreat Micro-ATX Board

Pros: -What can i say, it works great.
-I got it for $70.00 on Black Friday, and i'd definitely pay $90.00 for it today.
-ASRock Extreme Tuning Something or another is a nice little program. Easy on resources, and it tells you some nice information. Has overclocking, but doubt it does much. Its a non-K CPU on an H77 board so that doesn't make since.
-Gobs of SATA Connectors(See Cons)

Cons: **These are more annoyances**
-Has a bunch of ASRock fast this, and fast that. Don't install it, its stupid.(Minus the ASRock Extreme Tuning Something or another)
-The audio connector is under the GPU if you use the 3.0 slot. Not a big deal, but i installed my GPU prior to the front audio, and spent forever looking for that connector. Learn from my stupidity.
-Gobs of SATA Connectors, but i guess your only supposed to use these ones that are sticking off the side of the board. I don't know, i only needed 2 so i didn't bother looking into the subject.

Other Thoughts: Very Happy, works good, has more features then other boards like it. What more can I say?

1 out of 5 eggstotal failure

Pros: the bios look really cool

Cons: everything, out of the box started having problems. memory slots were not working, new egg said the CPU needles were bend, which they were not, but asrock is such a bad company that they dont want anything back because they know its bad as soon as it leaves their hands.

Other Thoughts: dont buy asrock products unless you want to know what a bad experience is. product is horrible; however newegg valued me as a customer and gave me a refund even tho they claimed i physical damaged the motherboard which isnt true at all. And for that i thank you newegg. and will continue to purchase from them

Manufacturer Response:

Dear AsRock Customer

We sincerely apologize for any inconvenience this may have caused you. AsRock mainboards are fully tested to assure that they're working before shipped. The CPU socket pins on the mainboard are fragile and need to be handling with carefully. In addition, the CPU socket is covered with the cap to avoid damage the pins and should not be removed until installing a CPU. As always, we appreciate your purchase and constructive reviews are welcome.

Thank you

5 out of 5 eggsAwesome, plan on buying another

Pros: To Guy with RAM issues below: I'm running with 8G of this with no issues.

G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GB

Also running plug-and play back up drives (lap top hard-drives) using removable cage. Recognizes these perfectly as I plug in and out. No reboots required. Awesome! Haven't tried the E-SATA yet.

Cons: none

4 out of 5 eggsPossible Ram Issues

Pros: Alot of features. Almost everything works. Plenty of ports, fan headers. System (when I got it working) ran my 42" hd system beautifully.

Cons: Possible problems with ram compatibility. See below. SDD\SDD ports can prove difficult to connect cables with because of side mount if you are using a small case. If that is the situation you find yourself in, I reccomend connecting the cables to the sata 6 ports first, THEN completing install of board into case. There are two sata ports that face UP that you can use for slower components. (DVD)

Other Thoughts: Recommended Ram does not run at rated speed. Installed 2 sticks of Gskill Ram, stock #F3-12800CL9D-8GBSR2 listed as compatible, but did NOT run at rated speed. (1600) Board properly identified the ram and ran the ram at its rated specs, but the system would not stay running. Was forced to downclock. Removed everything from board with the exception of the SSD drive, CPU and Ram and had trouble with crashing, video corruption, and freezing. Ran the board with onboard cpu video only and tried with older Geforce 460 with same problems. Ran with 1 stick of memory, in various slots, same problems. Testing with other stick, no go.

After doing additional research for this board, found that many people are having issues with ram. After several hours of troubleshooting, downclocked ram to 1333 and board ran fine. Paired with an I3-2100, Samsung 840 128gb, and a high quality corsair power supply. Ran bios on default settings. The downclocking issue isn't worth my time and trouble to RMA, as it isn't a gaming pc. Leaving open the possibility that the ram is faulty, and will try other ram when I get the chance. If it is incorrectly binned ram, then the board gets five stars. Will update once I find out.
