Summary: Had to RMA due to instability with the BIOS & USB 3.0 ports. Bought an Asus P8Z77-V Pro instead. No issues. This Gigabyte board, however, has better onboard sound, and was excellent for gaming in the sport time I had it. But stability is God, and I decided to get the Asus instead. No regrets.
Summary: Installed with an Intel Core i7-3770K Quad-Core Processor 3.5 GHz and a 750GB SSD, and this combination is outstanding. Overclocked with no problem. Outstanding for gaming. The installation was simple. But the manual should be improved. There is a great YouTube Video at , which I highly recommend.
Summary: This is a great board for the price. I used it to build a gaming computer. I used the Intel i7-3370 processor with it. It boots up 10x faster than the Gigabyte board I purchased 2 years ago. It has lots of ports. I highly recommend it.
Summary: I've order about 5 of these since they came out and I've had 3/5 been bad on me. I'm currently using one for a media machine and it works great. Has been for the past 8 months. The other 3 all went into this boot loop issue or had defective ram slots.
Summary: same as the z77x-ud3h only difference is more power phases, 2 ethernet ports which combined with a switch can increase your bandwidth, more sata 6 Gbps ports,more usb 3.0 expansion room,and a better integrated soundcard than the ud3h.
Summary: Board ended up not powering up my PC, but the guy installing it said he may have sorted it out so that wouldn't be the boards fault then. I had zero issues returning to Amazon, so just a slowdown on my install.
Summary: I love this board. It installed without any problems and runs great. The dual BIOS, on board power button, CMOS reset button and 5 6GB SATA's are great upgrades and the best part is that it installed without any issues at all.
