Pros: Once the BIOS is updated, this motherboard is rock solid (running 8.1). Temps stay cool, though I don't overclock and cannot provide information regarding performance settings. Intelligent layout; everything just seems to fit great. Excellent clearances for CPU cooling. I personally put a CPU liquid cooler and later a super-large Noctua cooler on this board with no problems.
Cons: I was unable to get the BIOS GUI to connect to the servers to download an updated BIOS. I was also unable to network configure the motherboard through the BIOS GUI. The USB flash BIOS didn't work for me either. Until the BIOS was updated, the BIOS GUI was unstable. The cable on the wireless antenna is fragile and probably incapable of withstanding pets or chidren. My bluetooth radio is showing a problem, but I'm not convinced that this anomaly is hardware-related.
Pros: Great Product value. This motherboard comes with a ton of useful features and the built in Wi-Fi makes it convenient to set up.
Cons: One of the USB 3.0 ports was not working. I confirmed this was the motherboard by switching my USB 3.0 cables. I sent an email to tech support and got no response in 2 days. I called tech support and explained the problem and they informed me I would have to exchange the board through Newegg. Given the relative minor issue, I have decdied to keep the board rather than undo my build.
Summary: BIOS is upgradable via the internet directly from BIOS, but ironically, this feature too didn't work until I upgraded to the 2.10 BIOS.
Pros: Lots of USB ports, AC wifi, Z87 chipset, lots of SATAIII ports, 4 case fan headers, 32gb RAM supported, UEFI BIOS, backup BIOS, CMOS reset button, debugging LEDs, heatsinks on chipsets where it matters, enough space for a reasonable CPU cooler w/o blocking a DIMM slot, legacy PS/2 port, PCIe 3.0, 1150 socket.
Cons: By far, the biggest con was the initial BIOS (ver 1.30) which didn't play nice with USB 2.0 devices (like your mouse or keyboard) on the USB 3.0 port when in BIOS. That was fixed by flashing to the latest BIOS.
Pros: Great features, AC wifi, two usb 3.0 headers, and 4.0 Bluetooth. Very detailed manual that should be easy even for a novice builder to follow.
Cons: Bios freezing (version 1.30) and very glitchy. Also would only recognize my G.SKILL PC3-17000 as 1600 not 2133, this was all fixed with Bios update 2.10 which can be installed via lan connection. Other minor issue I had was no sound output on HDMI port even after installing driver from provided disk, this was fixed by downloading latest driver from ASROCK website.
Pros: Fast Boot takes about 3 to 4 seconds from the moment I push On button. I use Plextor M5P for booting. Set OC to auto and I get 4 Ghz (can go a lot more, but no need) keeping the CPU temp. in 50 Cel or less. Updating the BIOS specially the 2.10 by Instant Flash was very easy and rewarded. No issues of incompatibility with any of the other hardware that I installed in the motherboard.
Cons: I just did put together this motherboard yesterday, it came with BIOS 1.3 and it was crashing often, updated to 1.4 and it was even worst. Luckily today was the release of 2.10 (thanks Asrock) and it works perfect (I went to pretty much everything in the BIOS, and even left the computer in BIOS for a couple of hours and no issues). The WiFi antennas are a little bit weak, don't be too far from the router.
Pros: I needed a dual-ethernet Z87 board and this one delivers. Rock solid so far and running slight overclocks on my 4770K and Vengeance Pro memory.
Cons: Two fan headers are in a weird place between the CPU socket and the first expansion slot. They could not be in a more inconvenient spot. Chose not to use them for cable management reasons. Otherwise I have had absolutely no issues with this board.
