2 out of 5 eggsMixed results: Mostly RAM and Wake issues.

Pros: It's pretty, it has lots of wonderful ports. It takes my CPU.

Cons: I load this up with 64GB of DDR3 1600 from day one, and it has some stability issues. I'm using non aggressive, normal, even 'stable' settings in their later BIOS.

If they could fix the wake from sleep issues I have, that'd be a plus.
If I put it in sleep, i quite often have an issue where the bios corrupts and will infinite loop, no bios screen. I have to power off and it tells me it's reloading bios from the backup. This is distressing and sometimes a daily occurrence.
I'd like Gigabyte to contact me if possible. Thanks.

Other Thoughts: I'm street smart AND book smart. I have my degree in Maryland from UMBC in CIS Systems Analysis/Design and a concentration in Networking, a respectable 3.44 avg, sadly non IT classes had to be taken.
I've done PC builds for 20 years, and THIS is the main stickler, Thankfully i've been lucky it's never been for a customer like this.
This is probably the first motherboard i've really hated.

2 out of 5 eggs

Pros: Lasted over two years. When it works - its great.

Cons: Motherboard stopped working after two years. I returned to manufacturer and they sent me out a used repaired board that failed almost immediately. Sending the second one back. Will follow-up later on the third board.

When getting someone else's board you may run into problems loading your OS and other Microsoft software as 'they' see it as a new build. Also you don't know what kind of mileage the other board has (maybe it was overclocked to where it may have a shorten life).

Other Thoughts: Extremely frustrated with Gigabyte's customer service. Think twice about this brand.

1 out of 5 eggsGA-X79-UD5 problems, problems, problems

Pros: lots of ram capacity and competitive features at the time this board was released.

Cons: 1- trouble from the start but updating the bios seemed to lessen the frequency of the crashes.
2- swapping new power supples and ram (all correct specs) never solved the problem completely. It would run for a while and then crash or freeze up & it would sit for months before I would try to use it again.
In the past I've had good experience with Gigabyte motherboards but Gigabyte needs to step up to the plate and put out permanent fixes for SO many problems I see posted about on here. This was a very expensive board. I needed it badly for something to study for my job and again last week it booted up and died and now wont start again and I NEED it to run 64 gb of ram. This was a very expensive board that has a lot of expensive hardware attached to it that has just sat and sat. Hopefully Gigabyte will come through with either a 100% fixed board or refund my money. 6 core processor, 64 gb of ram, great graphics card, top notch power supply and it's just sitting. Can you help gigabyte?

Other Thoughts: Gigabyte can you help? I bought this board new when the came out and it was pretty expensive.

4 out of 5 eggsFair board, great support

Pros: The technical support was great. I got the board back from RMAs in a timely manner, and they were willing to replace it multiple times.

Cons: Yeah, the RMAing is pretty aggressive. Nearly every three months the board would decide that it didn't want to work any longer. One day the system would just fail to boot, and the power needed to be removed.

Removing the power from the wall outlet meant that everything in BIOS would wipe clean. The RAM timing needed to be reset (XMP never correctly detected), the boot order was garbled, and the system would not respond properly to mouse input for a couple of boots.

Cue an RMA, followed by a new board with a new BIOS (there was one per month for the first few months), and suddenly everything functioned again.

I never could pin it down (tested PSU, had Intel replace the CPU, OS drive worked in another computer, and the RAM passed MEMTEST), but at least the replacement boards reached me quickly.

Other Thoughts: My past reviews have been harsh. I'd assumed that a board costing as much as this one would be 100% functional out of the box. Unfortunately, x79 seems to be a problem for all manufacturers.

I need to give Gigabyte services a big thumbs up. I can't state how awesome they've been, and they are the reason I will buy Gigabyte in the future. Experience with other manufacturers has taught me exactly what value I put to a three week down-time.

2 out of 5 eggsMuch dissappointed

Pros: Solid build, nice looking, enough USB 3 and Sata 3, 8 DDR3 slots

Cons: Windows 8 Drivers not supplied with CD, downloaded drivers not useable before OS installation. Won't post with all eight memory slots populated. No timely technical support!

Other Thoughts: This is my 5th build with Gigabyte MB. With the last one (GA-Z77X-UD5H), I was so happy with it that I've even reviewed it as "another win for Gigabyte"! Unfortunately, not always!
First, the system didn't post, just a long series of beeps. I removed 4 memory sticks, then it posted OK, allowing me to go into BIOS to set proper timing, then re-installing the full memory set (8x4GB) OK. Next step: no way to install Windows 8 because the supplied SATA drivers on the CD are for Windows 7 and before, so Windows installer won't work. Tried BIOS F12 and F13p, no difference. Sent a technical request to Gigabyte, wait for two days now without any response. Today, I installed Windows 7, with all the supplied drivers, then try to install Windows 8 again, on another drive. Suddenly, everything works fine, even without Windows 8 drivers!
This MB has been sold for over a year now, and Windows 8 has been out for as much, it's very sad that Gigabyte doesn't include an installation CD for W8, this MB is not cheap!
Up to the previous build, I haven't got any problem with any Gigabyte MB, so I didn't know how poor is its tech service. Now I know, so beware, if you got a problem, you're on your own! Now, I'm praying for a smooth operation from now on, and for the next build, I'll seriously consider other alternatives.

4 out of 5 eggsPretty good.

Pros: Stable with 4.0Ghz 3930K, 32GB 2133MHz G-Skill mem, 2x Samsung 840 series, 2x GTX680, AX1200i. Board features are OK, I used the add-in wifi/bt card in another computer.

Looks nice.

I use this system exclusively for gaming and am overall quite pleased.

Cons: Couldn't get XMP to work, machine crashed. Once I entered in the memory timing and speed manually it worked fine.

I still get an occasional bluescreen followed by an "overclocking failed" message. This forces bios but I don't make any changes, save & exit, then all is ok.

Other Thoughts: CaseLabs cases are the best. I wish newegg would sell them.

1 out of 5 eggsMy Last Gigabyte MOBO

Pros: Nice looking board, lots of promises.

Cons: (I’m going to mention the highlights because there is not enough room for the whole story) I purchased the original MOBO on Feb 16, 2012 and immediately started having problems. By this time they were on REV F8 of the BIOS. After weeks of dealing with Gigabyte tech support they determined that the X79 Chipset was bad, issued me an RMA and we swapped boards. The replacement looked like it had been through the ringer, scratches on the CPU frame, thermal paste everywhere, one of the keepers for a RAM slot was broken and the list goes on. Even so I proceeded with the build. By this time it was sometime in April.

To this date I have not been able to stabilize this board. I am now on BIOS F12, which is a slight improvement but still buggy. My major problems are as follows:

1. Serious compatibility issues with Gigabyte’s own updates, for example, I just tried to install the X79 chipset update and it gives me the following error; “Not Compatible With This Chipset”. I have had similar issues with other updates and it seems that the only software that will work with this board is what came with it.

2. Freezes frequently, can’t figure out why, it happens on boot. Reloaded the OS too many times to count.

3. When the unit freezes and you hit the reset button, nothing happens, you have to hold the power button until it shuts down, then when you hit the power button, it comes on for 2 seconds then shuts down and will not boot until you unplug the PSU, wait 30 seconds and plug it back in.

4. It seems to have issues with SSD’s, the only brand I have been able to get to work reliably is Samsung, don’t know why, all others, including Intel, gave me fits.

5. RAM has been an issue with both boards. I started with 32 GIG and worked with the RAM manufacturer to get it to work until they threw in the towel and offered to take it back. I now only have 8 GIG on the board, anything over that seems to cause problems.

6. Every once in a while I get the dreaded black screen that says it was not able to load the OS and wants to try to repair it, never works again. I have gotten to the point that I just reload the OS and start over.
(there's more but I don't want to beat a dead horse)

Other Thoughts: I have now given up on this MOBO and on Gigabyte. I don’t know what happened to them but QC seems to be a thing of the past. I build 2 or 3 systems a year, some for customers some just to play around with, this was supposed to be a gaming rig but now I’m going to salvage what I can from the MOBO and switch to another vendor.

I have used several brands of MOBO’s and when I have had problems tech support has always been helpful until now.

I suggest you avoid this MOBO and buy from someone else.

1 out of 5 eggsBad

Pros: I have no idea, it doesn't work yet.

Cons: WARNING: This motherboard comes stock with Bios version F7. This version only supports 2 processors, neither of witch are sold by newegg. If you buy this motherboard with ANY LGA2011 CPU sold by newegg IT WILL NOT POST. You need to upgrade the bios before it will work, but you can not upgrade it without a CPU that you can't even buy. This is the cause of all the previous posters "Wont boot issues"

Other Thoughts: CPU support list:

I'm having to take mine to a local shop to have them update the bios for me. Absolutely ridiculous for a $300 MB.

Manufacturer Response:

Thank you for your comments. Honest and constructive opinions are always welcome. We apologize for your difficulty with your Gigabyte product.

We do not control the inventory level of vendors. However, you may send your motherboard to our Service Center for a free BIOS update. If you require further assistance, please contact us at with the case number 2013011505 in the subject line.

4 out of 5 eggsWorth it!

Pros: I like the structure and distribution of connections of it. Nothing is rubbing or near nothing. I have it water cooled and my CPU block fins are lengthy which I thought it was going to hit the rams and not even close. I like the new Bios 3D interface. I really like I got this board. Over clocking few times it failed and the clearing cmos button on the back makes it easy to get back on track. I been using Gigabyte for a while those PC are still running, I hope this one does too.

Cons: When I got it out of the box it handles 40GB of ram but after updating the Bios it took the 64GB.

Don't install the programs from the CD if installing in a Windows 8 PC, down load it. The icons won't open but you can manage running them from the taskbar.

Other Thoughts: My other PC: GIGABYTE GA-EP43T-UD3L LGA 775
-Intel Quad Core 2.6GHz
-16GB Ram, Mushkin Enhanced Silverline 1333MHz
-Windows 8/64bit
-HDD 500GB/72k RPM/ 64MB Cache partionated into 220GB for the OS.
-1GB HD 6870

New PC: Gigabyte GA-X79-UD5 LGA 1120

-Intel Quad Core 3.6GHz i7 / 3820
-64GB Ram, G.SKILL Ripjaws Z Series, 1866MHz
-Windows 8/64bit
-SSD 256GB, OCZ Vertex 4
-1GB HD 6870
-PSU 850W Antec

And both take the same booting time, 28-34 seconds, which I don't get how can it be.
