Since this was my first PC build, I was a bit scared about the build process as well as the possibility of receiving a faulty motherboard, but after carefully installing all the components, the motherboard was able to POST on the first try, which is always a good sign. After installing the OS and updating all drivers, I tested all my installed components and had a problem with my USB 3.0 card reader which utilizes the on-board USB 3.0 header. I figured that maybe the BIOS firmware was at fault and although I was a bit hesitant, I ended up flashing the BIOS to F18 which was a simple process and went without a hitch. (After more testing and online research however, I narrowed it down to the card reader being the culprit.) One good thing about this motherboard is that in case you screw up your BIOS, there is a backup BIOS that loads in case you screw up the first one.
Overclocking was one of the things I definitely wanted to do so after my initial setup and after tons of research and reading, I entered the BIOS to tweak the settings. Adjustments through the BIOS were extremely simple in regards to CPU clock ratio and manually setting a CPU Vcore voltage.Read more ›

I recently ordered 3 of these to build a couple identical computers and two ended up being Rev 1.1. Something very irritating happens with both of them.
First, I boot into Windows 8, then I shut the computer down. Moments later, my entire home network "stops working" as surely as if I had unplugged all the network switches, router, and DSL modem. If I unplug the network cable from this motherboard or boot back into Windows, everything goes back to normal. If I then plug the cable back in or shut it down again, the whole LAN dies again. Whenever this network disruption occurs, the lower light on the LAN port on the back of this motherboard blinks at a slow but constant rate. About one blink every 3 seconds. Normally, this light blinks randomly.
Updating the BIOS from F17 to F18 had no effect. Disabling the onboard network adapter caused POST to fail (I had to clear CMOS settings after that).
Gigabyte support recommended I use the network driver from their website instead of the one provided by Windows update. That fixes the issue, but the issue can still come back if the OS is reinstalled or "refreshed" or if the driver is rolled back. In order to avoid this causing problems in the future, I installed 3rd party network adapters and physically blocked the onboard LAN ports.
Also worth mentioning: In case you are concerned about your CPU fan taking ages to start spinning with this board, that seems to be the intended behavior.
