Pros: Plenty of features. Modernized and current. Plenty of utilities included on the CD if that's something that interests you.

Cons: I received my first Pro 4 from Newegg and it had two dead ram slots, channels A1 and A2, meaning I had to place my two RAM sticks in the 3rd and 4th slots- preventing me from running in Dual Channel. I sent ASRock an email immediately and received a confirmation email within 24 hours. 4 weeks later and I have not received a single response. There is almost no way to find an 800 number on their site, and even when Newegg tech support provided me with the number, the automated system sounded cheap and foreign (no offense, but it was unprofessional sounding to listen to). Not only this, but when calling, the automated service simply said there were no techs available to speak with, and that I could leave a message, which I promptly did- in detail with contact information. 2 weeks later, no response. I had the motherboard RMA'd with a replacement, which Newegg was willing to provide for me, although explained that if there were any bent pins, regardless of how it happened and even if it came out of the package this way, I would not be refunded. I received my second motherboard in retail packaging, as expected. I removed it from the protective plastic, only to see slight streaks of white smudges on both the board itself, and on the metal casing that would soon clamp down over the CPU. This could only be what I would think to be thermal paste, but is unacceptable from a retail package. I gently smudged some of it off to ensure it wasn't caked on, but was sure to leave it there so Newegg could see when/if I sent it back also. I installed my RAM on A1 and B1 for dual channel, and much to my delight, the system started fine. Shortly after a fresh reinstall of Windows 7, I had encountered issues where, upon startup, I would lose keyboard and mouse functionality and could not even enter my password to log in. After a few attempts, I was finally able to enter safe mode and things seemed normal. I began to get artifacts with the on board display, blue and black static-y checkered striping and white noise, and the keyboard and mouse would become unresponsive. After more troubleshooting, even with a GPU installed, the same freeze would happen, only without the on screen artifacts. The display of my desktop was visible, but any video or audio being played would stop dead and my keyboard and mouse again, unresponsive. I finally reinstalled the original motherboard with the faulty ram slots, and so far so good. Mind you, 2 of 2 motherboards were defective in their own ways, and ASRock tech support is nowhere to be found. Newegg is willing to RMA my board again, or even replace it with a different brand, but at this point I'm almost scared to even attempt a new install.

Overall Review: There's not much to say. I will never buy ASRock again purely due to their lack of support, and further more because two of the boards I received were defective.

Pros: None so far.

Cons: I get an error in that it won't read both stick of memory, and I can't get into windows to run any drivers. One egg because I emailed ASRock support on 3/29 and have yet to hear a peep from them, other than their acknowledgement of my request. I've search the net for answers, and joined TweakTown forums to try to remedy this. I suspect its a simple fix, but I am 10 years removed from geekdom, so I don't what it is.

Overall Review: I'll do a new review once it works.

Pros: rich feature set, solid construction, simple yet complete bios. it is also a beautiful board. the layout is optimal for my build. everything is in the right place. cables included is a big plus to me. packaging was protective and secure.

Cons: none at this time.

Overall Review: your philosophy of use will determine how perfect or not you think this board is. personally this is the perfect motherboard for me. all the dedicated devices i plan to add fit perfectly into this board and it has every feature i wanted at a better price than competitors that couldn't match this specific layout.

Pros: Inexpensive, Reliable, Well built

Cons: None

Overall Review: Great motherboard!! Booted up the very first time, recognized my memory, dialed in the monitor and took me to what I think is the easiest BIOS interface I’ve ever experienced. Overclocking is very simple. The Hardware monitor is very informative and useful. The UEFI is well thought out and easy even for a novice like me. My rig shuts down, sleeps, hibernates and wakes all within seconds. Great investment. The manuals and software are all very useful. The components of my rig are below. I now have a computer that meets all challenges without delay. Mission Accomplished. Intel Core i7-4770K Haswell 3.5GHz LGA 1150 84W Quad-Core Desktop Processor Intel HD Graphics G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) ASRock Z87 PRO4 LGA 1150 Intel Z87 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard Microsoft Windows 8.1 - 64-bit – OEM SAMSUNG 840 EVO MZ-7TE250BW 2.5" 250GB SATA 6Gb/s MLC Internal Solid State Drive (SSD) Antec VP-450 450W ATX 12V v2.3 Power Supply - Intel Haswell Fully Compatible WD BLACK SERIES WD1003FZEX 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive Onboard Video/Sound

Pros: The best you can say about any product is that it works and performs as advertised. This is certainly the case with this MB. No problems with CPU (4770), memory and all ports and interfaces perform as expected. The new (to me) bios is a great enhancement and quite easy to use. This is my first ASRock product and I am quite impressed with its quality.

Cons: Not one.

Pros: intel gigabyte ethernet. flexible bios options, decent board layout, lots of usb ports, seems pretty stable so far

Cons: usb options in the bios could be explained a bit better see comments too

Overall Review: while not asrock's fault, do NOT accidently install the Z77 USB 3.0 drivers for the Z87 usb 3 controller. Intel has totally reworked it, and accidently installing the Z77 drivers will hose your windows 7 install.

Pros: It has a lot of SATA slots and integrated graphics/sound.

Cons: The board has USB issues, it had them from the beginning and I didn't return it because I figured I could put up with them and it is a major thing to install a motherboard and all your components, didn't want to have to do it again soon. If you set the change certain USB setting in the bios, your keyboard won't work in the bios.. So you have to reset it with a jumper. Even with settings that normally work, the USB can occasionally blue screen on shutdown, or underpower a device.. to try to fix that you have to change the USB settings.. and navigate around the no-keyboard issue. Also the motherboard's tuning software can crash and blue screen the system -- just by being loaded up, without any settings changed. Want Internet after installing WIndows 7 64 on it? Guess what -- no Internet till you download and install the motherboard's LAN drivers. So I'm out of warranty by now and still dealing with these issues today. What's my conclusion? I put up with it for four years -- but why would I buy Asrock again? Let me try a different brand.. I'd like a painless experience next time. I'm giving it two eggs just because it's served me all this time otherwise, but it feels like a one egg to me. I spent a lot on this board, I expected a happy and reliable experience, instead, it's been a long slog dealing with it.

Pros: The dehumidifier is such a great perk for this board since the computer was set in a basement. Along with the three awesome ASRock functionalities, x memmory, x usb, and x lan which all boost the hardware in different ways, this board offers a nice bios interface, a super-fast boot (one of the best on the market and all the other wanted properties of the moment. 32gb max, the latest lga haswell bridge and at the time I bought it, it had the best chipset, plus the box had a nice smell.

Cons: Well some area in the manual weren't quite well indicated. Made it difficult for me to find the proper connectors.

Overall Review: This is an overall good board with extras on a budget...
