2 out of 5 eggsBoard not reliable

Pros: Has some nice features, did what I expected when I purchased.

Cons: Has failed on me twice now for whatever reason, have RMI'd it once and will do it again. Going with another board.

Other Thoughts: For a 'military grade' board it doesn't seem to fit the build.

Manufacturer Response:

1 out of 5 eggsTwo in a row, total failures

Pros: OC Genie does what it says.

Cons: I am now RMAing my second board. Both of them will, as MSI puts it, LOCK UP/HANG UP/FREEZE. It starts off random and infrequent, then progresses to constant and unavoidable.

I've owned this board type since November. I've switched every other piece of hardware used with it and it still does the same.

I bought a different board (ASRock) already and will just sell off the returned board after the RMA. I'm done. Fool me once, shame on you, fool me twice, shame on me. I can't afford to have another bad board that with all it's freezing and reboot loops will fry my SSDs or CPU.

Other Thoughts: i5-3570K @ stock and @ 4.2 with OC Genie
16GB Dominator GT 2133
MSI GTX660ti

4 out of 5 eggsWorks Great, Except...

Pros: Pros- Easy installation, and plenty of expansion slots. Runs everything just fine once in the system, And also has Click BIOS II.

Cons: Cons- The onboard graphics (VGA & DVI Ports) that came on the board were DOA. But if this happens to you just get your graphics card in there and connect directly to the graphics card. Dont worry, the motherboard will recognize it right away.

Other Thoughts: Overall, I still recommend this board.

Manufacturer Response:

3 out of 5 eggsAwesome board until it stopped. rma in progress

Pros: Awesome board.
Oc'ed my 3770k to 4.8ghz no problem.

Cons: After about 11 months, it stopped booting. It would just go into a continuous boot loop.

Other Thoughts: Currently being rma. If it comes back in working order in the time frame specified, I will give it 5 eggs

5 out of 5 eggsGreat Motherboard

Pros: Looks good
OC Genie works great
Power button
Good manual
2x PCIe 3.0 slots

Cons: No PCIe x16

Other Thoughts: Great board! I have had it for 5 months and haven't had any problems. Booted up first time, and was easy to get everything installed on. OC Genie 2 works great. Got my i5 3570k to 4.2 GHz with just the push of a button, and it runs around 27 degrees celsius idle with the EVO 212 cooler. Has good expansion options but unfortunately there is no PCIe x16 slots, so a lot of card addons have to go into the PCIe 3.0 or 2.0 slots, which is where your graphics cards can only go. Overall great board!

5 out of 5 eggsVery nice, full-featured board

Pros: Lots of features, SLI/Crossfire, easy-to-use BIOS, price/performance, sturdy well-built feel to it

Cons: The main con is that the SATA connectors are positioned at the front of the board facing forward instead of upward. I don't know why some board manufacturers still insist on situating the connectors in this way, but it makes plugging in SATA devices a pain in the ---. It's enough of a hassle that I almost docked an egg for it.

Other Thoughts: Overall, this board is packed with features and was easy to install. Also, I'm a pretty big sound enthusiast and am pretty picky when it comes to audio quality, and the onboard digital sound chip on this board is quite nice.

The board posted the first time it was turned on with no fuss. As a warning, one thing I had to do in order to get Windows 7 to install was change the SATA config in the BIOS to from AHCI to IDE, so if you run into any issues with the Windows install disc hanging at start-up, then that is most likely your fix.

So, other than the SATA connector positioning mentioned earlier in the cons, this board really is a fantastic value for everything it gives you, and should be a strong consideration for anyone looking to move to an I5 or I7.

5 out of 5 eggsBeautiful board

Pros: Overclocking is literally as easy as the push of a button

Cons: The CPU socket is close to the memory slots, so if you have a large HSF it may get in the way of only one slot depending on your RAM physical size

4 out of 5 eggsFirst Impressions

Pros: Boots fine
GUI is good
Works well with SSD and HD together

Cons: Winki 3 partially functional

Other Thoughts: Running Win 8 and an SSD with MB in a fresh build. So far, so good, but I haven't stressed the board with any gaming to date. Winki 3 is a little gimmicky, but if it worked, you could almost get by with it for simple tasks. Keyboard functionality was sporatic with Winki 3. For example, I could could clear the default SSID on the setup screen but I couldn't type in the correct SSID for my home network. For file searches, the keyboard did work. Just funky little stuff with Winki that marks my initial impression down a little.
