1 out of 5 eggs

Pros: It had lots of usb ports.

Cons: I give this board a big fat goose egg (0), since Newegg doesn't have zero as an option.
The board finally burned after a few years of use. Sent my RMA number in and they sent me a replacement 1366 socket board, that one also caught fire. Gigabyte's warramty service is horrible and their products are way under par. It has been taking them over 2 months to get anything done. DO NOT buy from Gigabyte EVER!

5 out of 5 eggsBack from the Dead!

Pros: Hackintosh! Compatible. Overclockable. Gigabyte.

Cons: expensive. Realtek Ethernet (not Intel).

Other Thoughts: I must have done something dumb, because when I transferred my mobo to a new case, it wouldn't boot. Removed all except mobo, cpu, heatsink, psu, one stick of ram and still won't even get to BIOS. just fans spin up for 1 sec, then off, and repeat. No beep codes. So I sent it back to Gigabyte fully expecting that to be a dead end. Less than a week later I get the board back FULLY FUNCTIONAL!!!!! REALLY?? Kudos to Gigabyte. Who knew. Flies in the face of all the other reports all over the internet about Gigabyte failing when the boards fail. Oh, and I'm sure the failure was MY FAULT.

1 out of 5 eggsNice look board but unstable

Pros: I was using the board with a 6 core i7 and had the board load with 24 GB of OCZ ripjaws RAM. It was easy to configure, but overtime the 6th DIMM slot (slot #5 in the CMOS) went south causing instability problems until I had to replace and evaluate the RAM in different slots.

Cons: Motherboard failed within the warranty period. Now, I have been waiting in the phone queue for 30 minutes waiting for someone at Gigabyte to answer the phone and give me an RMA number. The problem is that I cannot be without my computer for 6 weeks which is my estimate of what the turn around time will be to get this board replaced. Oh, and try and find a board now with a 1366 socket, so I am worried that I am up a creek with out a paddle.

5 out of 5 eggsLong time owner

Pros: I think this is a great board. I've had it for as long as I've had my truck, about two and half to maybe three years. I have had zero problems with it. I'm going to update the RAM to 12 gigs, the video card and an SSD for the OS. Give this old system a bit of new life. BIOS was easy to navigate and perhaps it lasted so long because I have fairly good cooling but I also have never overclocked any part of my system.

Cons: Whenever I transfer data files across my network the computer slows down really bad, never used to happen and that could just be attributed to the netgear usb stick.

Other Thoughts: I think some people just get into a bit of bad luck. Every two years I build a new comp and have only had a bad power suppply on this board. I thought it might have been the board so to try it out I connected my old power supply and it booted up great. I will never buy another Rosewill power supply as the two Thermaltakes I have had for awhile have never crapped out or showed signs of slipping away into the abyss.

5 out of 5 eggsKiller Mobo

Pros: Haven't had a single problem with this motherboard in almost 2 full years of ownership. Have been running a core i7-950 at 4Ghz for about as long @ 1.312V without a single issue. BIOS is user-friendly. Easy to mess with voltage settings

Cons: None

Other Thoughts: Would definitely buy from gigabyte again. Plus they have cool stickers.

3 out of 5 eggsX58A-UD3R

Pros: Have had this motherboard since Aug 2010. There are Two Models Baring the Model numbers X58A-UD3R. There is a Rev 1.0 And a Rev 2.0. They are similar but different. Rev 1.0 8+1 phase and Rev 2.0 is 12+2 phase. And placements differ if you look at both board side by side.

Cons: I have had problems where i thought my SSD died. Would not boot or see the hard drive at all. Then i put in my WD Raptor 150 and installed windows 7 and a week later i got a report that my raptor was failing. Then i decided to switch my motherboard to my ASUS P6X58D-E and would not boot don't know why got to look into it only used it for a few weeks. So i put my Gigabyte together again and just for S hTs and Giggles put my Solid state back in. Well hell its back up and running on the solid state. I think my board is about to become a test board.

Other Thoughts: If you see this board on a auction site cheap. There is a reason. Don''t matter Rev 1 or 2.0. there gonna fail after a year or later.

3 out of 5 eggsNOT a SATA 3 capeable drive

Pros: Great overall MB, everything works well, easy to tune

Cons: Does NOT work in SATA 3. The Marvell controller is not capable of nearly the speeds necessary to call it SATA 3 as advertised. Use the intel SATA 2 drives and you get a faster speed than the SATA 3 ports. I bought this drive with the intention of upgrading to a SATA 3 SSD, which I did only to find it running slower than SATA 2 speeds on the SATA 3 port. Really disappointing...

Other Thoughts: Everything works great outside of the SATA 3 ports, I wish they didn't advertise it as a SATA 3 board.
