3 out of 5 eggsYou're on your own

Pros: A good, rock solid board, for the most part. TWELVE SATA II connectors, 10 SATA, 2 eSATA (FINALLY Gigabyte!) Lot's of USB connectors. Support for XMP (eXtreme Memory Profile) RAM automatically. I didn't have to do a thing to get my 8 GB G.Skill DDR3-1866 to run the XMP. I've found other boards will automatically choose the slower rate first and then make you jump through hoops even to get to the rated speed.
The board was also a breeze to set up, thanks in part to some changes to Gigabyte's BIOS. They've rearranged the CPU and RAM tweaking parts of their BIOS into some more logical subdivisions. I found it to be a very welcome change, because, in the past, I've found myself hunting all over their (rather extensive) BIOS looking for one single parameter switch.

Cons: First off, I want to reiterate that I think this is a terrific motherboard. I would give it 5 eggs if not for Gigabyte's HORRIFIC "Technical Support"! (See below.)
Other than that, the only flaws are 1) that first PCI-E x1 slot that's blocked and nearly useless. Gigabyte, could you at least TELL us the maximum length of a board that will fit? The manual essentially just says, "The first slot is blocked! You need a REALLY short board if you want to use it."
2.) There's also some resource sharing that's not apparent at first. The last x16 slot is billed as a x4 resource. But, it's set to x1. If you set it to x4 (in BIOS), you lose the second x1 slot (the one that's NOT blocked) and BOTH eSATA ports!

Other Thoughts: The biggest con, and the reason this board loses 2 eggs, is Gigabyte's useless tech support. I have only one video card, a Radeon 4890, in the first x16 slot. There's nothing in the x8 slot. But my card, according to both GPU-Z and ATI Catalyst, is running at x8 PCI-E 1.1, not 2.0. I gave their technical support a detailed explanation, and told them my entire card slot layout. The first response was "How do you know it's x8?". Days later I got, "If you have a card in the x8 slot, then the x16 runs at x8" I TOLD you that slot's empty! After that: "Did you update the driver?" I TOLD YOU THAT TOO! Days more... "Did you update the graphics card firmware?", along with, "Change the video card out." Now I also told them that GPU-Z AND Catalyst say the card is reporting that it supports x16/2.0, but the BOARD is only reporting x8, and those responses were all that Gigabyte's Tech Support could give me! As I said, if you get this board YOU ARE ON YOUR OWN!

4 out of 5 eggsMoslty Great

Pros: Works fine out of the box with a bios update and the included software makes over-clocking easy and very stable. Can't understand others who complain about the board, perhaps the bios offers too many "toys" for some.

Cons: Seems to be a problem with Windows 7/64 bit staying connected via the lan port to my router at boot up. May well be a Windows 7 problem and not the board. Working on a resolution. SATA cables are too short but stretch to fit with a little effort.

Other Thoughts: Replaced a DFI motherboard running XP (still in use) and the 2oz copper feels like 2 pounds, this motherboard is solid. Would like to have had the com port cable included for the price for my FAX modem connection but not a deal breaker. If it works as well and as long as my DFI motherboard ... I'll up the rating to 5 stars. Make sure to update the bios before any system install. The 30 day return only policy almost scared me away. Will advise review in a few months.

1 out of 5 eggsMore Than 1 Month Later With The Board

Pros: More than one month before I wrote here an "ALMOST Perfect Board". But since that I have tested this Board with WinXp SP3 32, Win 7 32 + Win 7 64, eSata and graphic cards - I would say almost all the fuctions the board should provide. Now I would like to correct this statement and apologize for it. My statement was wrong.

Cons: In more than 35 years with computers I had many boards. I set the Bios and they worked.

This was my first Gigabyte board. Playing around in the Bios gets almost a daily business now. But many things still don't work. Every combination of settings in the Bios seems to create different problems. Then add new drivers and a Bios update and the game begins again.

My problems are many and until now there seems to be no fix. But I am getting tired of looking and hoping for fixes. It took a lot of time to search and try and did not bring anything at all in the end until now. Only today for instance I spent one hour again because the Turbo Boost works sometimes and sometimes not with whatever settings in the Bios. But this is only one of my many problems.

Other Thoughts: For sure the last Gigabyte product in my life. Never want to have such a nightmare again.

1 out of 5 eggsNot Pleased

Pros: Great feature set. Exactly what I was looking for. I was going to use it as the platform for a high power Media Center PC for a friend.

Cons: First one didn't work out of the box. Started, lit up for about 5 seconds and then restarted. Over and over and over. Second one did the same thing only it would restart every 2 seconds. Not pleased.

Other Thoughts: Newegg was great though. After the second one didn't work they gave me a refund which I immediatly spent with them on a different manufacturer's board.

5 out of 5 eggsNice features, read the details

Pros: This board has a lit of nice features, the on-board sound is very good, the network ports have some very cool fail over features. I have had several Giga-Byte boards and have always been extremely happy. This is a good mid range board, maybe a little over kill on the features, but very nice.

Cons: Nothing yet.

Other Thoughts: Know what you are buying. Read the documents on the PCI-e x16 slot and how they work with SLI or Cross-fire. The board is good, but if you are looking to do a gaming rig, or SLI/Crossfiring video, you may want to look at the Bloomfield boards. The Bloomfield chips have some of the same price per dollar stats as the Lynnfields, but the underlying tech may make the a better choice for the monster gaming rig builds.

1 out of 5 eggsDon't count on their techical support

Pros: What I wrote in my review before. But be aware that the GA-P55A-UD7 is just around the corner and read my cons.

Cons: The technical support at Gigabyte is a VERY bad joke. It normaly ends that you should bring your computer to the dealer to fix the problem. There is not even a tiny effort to talk to you so that you can fix the problem yourself.

I did it and my dealer could not even handle the BIOS... Better to RMA it.

This was my last Gigabyte board.

5 out of 5 eggsTo N/A

Pros: Primary: 24-phase power design which helps with longevity of motherboard components and CPU when overclocked, 10 internal SATA headers on the motherboard.

Secondary: Just a few including: Advanced screen of Dynamic Energy Saver 2 has a few cool features, Smart Quick Boot, and Smart Recorder will let you know if the kids are on the computer in the wee hours of the night instead of sleeping.

Cons: Some of the drive cable connections are low on the motherboard, especially if you have a large tower. Make sure you have access to a web site or brick and mortar store if you need longer cables.

Long video cards in the first PCIe slot can cover 2 SATA connections and part of the SATA controller chip cooler. A second long video card in the second PCIe slot can cover 4 SATA connections and part of the SATA controller chip cooler. [This is where the Southbridge would have been located on older motherboards.]

On a personal side note, I wish Gigabyte provided a 24-phase power design for at least one less expensive motherboard that supported only one x16 PCIe version 2 slot so those that want to use 2 GPUs on a stick instead of traditional SLI or Crossfire [2 seperate video cards].

Other Thoughts: N/A on 10/22: You can download and save the motherboard manual to hard drive - you might have been better off if you had read it before making a purchase if RAM capability would have kept you from a purchase.

N/A on 10/12: There are many things that can cause your problem, to name a few, power supply, any voltage leakage or closed circuit in any component such as RAM, hard drive, case fan, any fan, remember this is just a few. Of course the motherboard or BIOS can be bad. If the second motherboard has the same problem you might want to take the computer to a good repair shop and have the hardware tested.

1 out of 5 eggsIts all someone elses fault!

Pros: Cheap board.

Cons: Their tech support blames everything on everyone else. "Third party" this and that!

Other Thoughts: If so many components are incomaptible, maybe they need to figure out why, Every other manufacture does not have compatibility issues. Don't use this Product or any other gigabyte component!
