5 out of 5 eggsP55 pro/usb3

Pros: Easy to manage and what I expected. Well worth the price.

Cons: Drivers are buggy. My LAN driver shows a red x but I'm connected to the internet and bios shows a gb connection. And the realtek driver keeps notifying me that a device has been unplugged/plugged in audio port when nothing is.

4 out of 5 eggsworked 1st try

Pros: everything works as advertised! I'm not overclocking, but it has all the functions and settings needed to do so. Expert reviews gave it their best buy award. good audio codec, has heatsinks where needed, cooler combo option allowing most lga-775 coolers to be used, which I took advantage of. many pro's!

Cons: only con, as others have stated, is that it is a full inch short of atx standards, leaving right side (ram slots, 24 pin connector, sata ports etc..) not held down perfectly, but anyone with a brain can minimize any potential problems by BEING CAREFUL. -1 egg, but honestly i've owned an msi 870a-g54 with same problem, just being picky.

Other Thoughts: if i could give the board 4 1/2 eggs, i would've. As long as nothing dramatic happens, I have absolutely NO hesitation recommending this budget board to ANYONE! Buy it, you won't be sorry, but as always RESEARCH BEFORE BUYING ANYTHING! EXCELLENT BOARD, received it in less than 24 hrs from clicking buy.

5 out of 5 eggsGreat board

Pros: Good price. Solid well made board.

Cons: Realtek audio.

Other Thoughts: My previous computer had an ASRock board and it has lasted for years with no problem. (Other then the Realtek audio) I just wanted an upgrade. The only problem with this board is that I get a periodic pop-up over the system tray that says a device has been connected or disconnected when I have not changed any of the connections. This only happens when I have the headset plugged in. I think this is not a hardware problem but actually a problem with the Realtek driver. Also the volume when using the microphone is not as loud as it should be. This is with the mic boost on and the gain all the way up. These to problems that I have listed seem to be problems with Realtek not the board it's self. Not bad enough to knock off an egg. I would still recommend this board. If better audio is needed you can always install a sound card.

5 out of 5 eggsAstounded

Pros: I found this easy to use with clear markings for my first solo build and it is well made. I loved everything about it and will continue to buy from ASROCK.

Cons: The 8-pin hookup to the mobo is on the upper left part and that always bothers me but not really a huge con.

1 out of 5 eggsNOT AS ADVERTISED

Pros: Number of SATA ports

Cons: This board is listed as supporting Raid JBOD. It truly does not. With out this functionality Windows Home Server will not recognise the disks, and will not install.
I will be returning this board to New Egg.

Other Thoughts: ASROCK's technical support sucks. The response to my question of how to configure the RAID for JBOD was "Check the manual" no where in the documintation is JBOD listed except in the features list.

4 out of 5 eggsWonderful!

Pros: Great budget board. Nothing fancy like the X58's. I didn't need all the additions from the 1366 models, so I chose 1156 and I am completely satisfied. I am coming from a Gigabyte 770(DDR2) and my system seems a little more snappier.

Cons: The layout is not the best. I took off an egg due to the placement of the 3gbs SATA ports. My Sapphire 6870 covers them completely. Why put the ports in line with the video card?

Other Thoughts: Other than the SATA ports placement, I like the board. Worked right out of the box with not one issue. I had been eyeballing X58 boards for about 2 months puting several on my wish list. I just couldn't justify spending the extra money over a 1156 board. I am not a hardcore gamer(love BF2BC, though), and the i7 950 was going to be overkill for me.

4 out of 5 eggsEffective, with Annoyances

Pros: Easy installation, straightforward slots. An excellent, non-forceful method of locking PCI-E cards into place. Plenty of USB space. Default settings ensure you're good-to-go pretty much out of the box.

OC Tuner and Intelligent Energy Saver are especially effective for my i7, especially in slowing down my noisy Zalman cooler when it's not chugging.

For ATX, it's very slim, making installation into the case very simple.

Cons: Certain things about the hardware design make me uneasy.

Several power slots for the case and CPU fans are placed very close to capacitors, and use a small latch to keep them in-place. The problem is the latch is almost always pointed in the direction of the capacitor, making removal of a fan-wire a tenuous thing without a needle.

Also, the board has far fewer anchor points to the case than my previous Gigabyte. This wouldn't be a problem, but the right-most side of the board has no anchors in the corners, and the board's primary power socket for the PSU sits on this space, and that side will desire to bend in applying pressure for putting the plug in the socket.

Other Thoughts: In my very short time with this board and it's accompanying hardware, I've encountered a number of infrequent problems, but I can't claim at present that these are the fault of the board, so don't take these as more cons.

When I first turned on my PC with the board, the computer turned itself on and off rapidly about three times before the BIOS lit up on the screen and went to POST. This has never happened since, though other things have.

At one point while rebooting, the computer failed to shut down and simply stayed on the shutdown screen for several minutes. I hit the power button, and the screen went blank, but the fans and leds all seemed like they were functioning until I performed a full hard-boot.

One startup took several minutes to go from the welcome screen to the desktop.

Just recently, a game of TeamFortress 2 seemed to end in a blue screen (stop) error.

These things could merely be anomalies, user error, bad RAM, or the motherboard is causing them somehow. D

Pros: Price. USB 3. Port space.

Cons: Will not work with Mushkin RAM

Other Thoughts: It loaded up easily enough and didn't have any problems installing my software but then it started to lock up. It completely froze and there was no rhyme or reason to it. It happened when I was running multiple apps as well as sitting idle. After hitting the forums, I discovered others were having this problem as well.

Apparently, there's a list of acceptable RAM on ASRock's website and Mushkin isn't one of them. If I'd known it would have saved me three straight days of trying to figure it out with memtest (which passed on all four sticks), coretemp, swapping video cards, etc....However, it will work with just one 2GB stick of Mushkin RAM, but not two, just in case you find yourself in a similar situation.

PS. Anyone want to buy 8GB of used RAM?
