Pros: 1) Nice design - Solid heatsinks - Quaility board - Color scheme 2) Bios - Easy Nav and usage 3) 555 features appear to work just fine 4) Win7 64 install was painless in RAID mode 5) Did not come across any hickups or kinks 6) 8 SATA ports + 1 eSata 7) OC 2600K to 49x on air (very easy compared to old Gigabyte x68) 8) Broadcom LAN is better than Realtek however it is not quite Intel. Still a very solid LAN. 9) Flashing the Bios in the Bios painless

Cons: 1) I wish the board a had few more PWM fan headers 2) The design of the extra power of Xfire/SLI placement (molex) was a bit clunky. Hard to make a pristine looking build with a cable across the board 3) The drivers are not exactly the newest on ASrock site. 4) I could be wrong - doesnt have dual bios (bummer)

Overall Review: All n All the Cons are just minor issue - nothing really with the board. The 555 tech worked fine- I have the same USB turbo on my external HD swapper. I was a bit concerned with the negative reviews however I went for it. Currently I am not disappointed. This is my first Asrock board all seems pretty good. Sidenote: I would highly recommend getting this board. Buy a SilverStone Sugo Series SG09B case - you can mount a massive heatsink in tiny case and with a massive SILVERSTONE Air Penetrator AP182 (170cfm of 180mm fan power). You can massive OC the board in tiny case. Trust me it rocks

Pros: This board overclocked my 3570k without a hitch. im at 5.0 ghz stable at 1.32 vcore on an antec closed loop cooler the h2o 620 to be exact. posted immediately and has been running non stop for almost a month! onboard power and reset buttons as well as a rear IO CMOS clear button. recognized my SSD and 3tb drive right from the start... granted i had my 3tb drive formatted to gpt in an older system so this might be why! GREAT PRICE!!!

Cons: only 6 usb ports on the IO not really a con... i just have a custom built case with no extra usb ports so i gotta swap my headset for my game controller sometimes.

Overall Review: this is my first intel build and i have 0 regrets. the components i selected are as follows ASRock Fatal1ty Z77 Professional-M 3570k cpu at 5.0 ghz cooled with kuhler h20 620 asus HD 7870 at 1250 core clock 1350 mem clock kingston hyperX red rated for 1600mhz 9-9-9-24 OC to 1866mhz 10-11-10-26 samsung 840 evo 120gb SSD Seagate barracuda XT 3tb 64mb cache 7200 rpm corsair GS700 power supply all installed in a custom modded hp case from 2007 also note i bought my motherboard from a-ma--zon as newegg would not ship to my PO box i Would recommend this board to all of my friends

Pros: I got new one that was rmaed. It works great. i5-3570k @4.4 with noctua nh-d14 cooler. ram overed @2000 9-9-9-24 I think can over more.

Cons: You should be lucky. If you got defective one. If you have huge cooler like mine, you can't use first pci-e. If you don't care about sli or cf, it's fine. The other 3 slot works at x16 single.

Pros: This board with a raideon 7950, 3770K, and 16GB Ram fits in a power envelope of 3 to 283 Watts @100% load with an average load of 108 Watts. Runs my Ram at 2133Mhz Clocked a 3770K to 4.0Ghz with only adjusting the clock multiplier.

Cons: None They thought of everything with this board.

Pros: Looks very nice (love the colors), ports are in good spots for my microATX system (only the most bottom pcie is slightly inaccesible). Once my system was finally fully set up everything runs smoothly. === Setup === CPU: Intel i7 3770-k GFX: XFX Radeon HD 6870 (soon to be Nvidia GTX 770 :) ) PSU: Corsair cx600m HDD: WD Black 1TB MB: ASRock Professional-M Case: Rosewill Line-M RAM: 2 x 4GB G.Skill Ripjaws Cooling: Corsair H60

Cons: Overcloking my CPU through BIOS caused lots of crashing to happen. Leaving the CPU not overclocked fixes this problem.

Overall Review: Fits well in my microATX case

Pros: -Board posted -TONS of overclocking features -has clear CMOS button -has a power and restart button right on the Mobo for workbenches -Red and Black look sharp -Has a cool debug LED on board

Cons: -2 of my USB 3.0's on the board do not work. Tried installing drivers etc

Overall Review: Good board with even better price but would be nice if everthing worked

Pros: I loved my old ASROCK/i5-760 setup but needed more than the max 8GB of RAM that board could take for some VM's I need to run. I still wanted a feature-rich small quiet system; which is EXACTLY what I got with this board. Install and setup was a breeze. Board has everything I could want. Layout is excellent, plenty of USB 3.0 and SataIII ports. More than enough fan headers, excellent audio and RAIS to boot. SO if you are looking for the PERFECT Z77 mATX board this is it.

Cons: None

Pros: This has been an awesome board. Bought it over 5 years ago, and still running strong. Over clocking is pretty simple. They have preset profiles, but I don't prefer that. I don't use all the features this board offers. Shame really

Cons: Software to monitor the board feels clunky, and outdated. I wish there was a newer piece of software that feels more MSI Afterburner. Other than that, nothing really.

Overall Review: Took a chance on a company that at the time had eh reviews, and had never heard of. Haven't been disappointed yet.
