Summary: Well Installed the MB and seemed to work got 1 beep which means good boot up to Post Bios Screen, tried 2 different keyboards and could not get into bios. Then it just started rebooting. I Checked online and known problems with same issues. Looks like this might be fixed with the z77 chips. I really like Gigabyte MB's! Have been using them for last 6yrs with no problems so i have ordered the Z77-ud3h board waiting on it to reinstall. Hope this helps you!
Summary: My experience tells me now that I'll never buy used again the first motherboard had bent pins in the processor socket, the second mother board had 2 dead memory slots, due to wasting to much time I'm going to use the second one and have purchased 2 8 gig memory sticks to take the place of my 4 4 gig sticks... however had i know i would run into this problem i would have purchased new.
Summary: I just bought this board and for a beginner the manual should be more detailed. I put it together and got it to work half way,the unit did not come with a driver's disk) I contacted GigaByte twice and haven't received and answer on where can I get the drivers- I was able to find one (for the network card) at their site but not the others. Good customer support makes me come back as a cutomer and I think I'm not coming back to Gigabyte. Javier R.
