GIGABYTE GA-990FXA-UD3 AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard

60% Positive Reviews
Rated #15 in AMD Motherboards


Pros: Great features, AM3+ Support, 4 DIMMS, Great looks

Cons: North bridge heat, No internal On/Off button


The Gigabyte GA-990FXA-UD3 is the lowest end AM3+ Motherboard from the 990FXA line from Gigabyte.
It has Four DIMM's supporting 2400 Ram, Four PCI-E 16x slots, Two PCI-E 1x slots and a single PCI slot. The entire motherboard
it black and is very sleek looking. It has heatsinks on the north bridge and mosfets. It has cooling on the FXA chipset as well.


This is a very good looking motherboard being fully black, with only some white writing on it. It has Four PCI-E 16x slots, two wired for full 16x
and the other two only wired for 4x. This means it supports 2-Way Crossfire and SLI at 16x/16x. The PCI slot is at that bottom meaning even with Crossfire you can use that PCI slot.

There is one internal USB 3.0 Header and three USB 2.0 headers. There is quite alot of room around the CPU socket
giving greater support for Ram and aftermarket cooler combos. There are Six Sata III 6gb/s ports as well. It is a ATX motherboard needing seven expansion slots, and the rear I/O has two USB 3.0, eight USB 2.0, 7.1 Audio ports, two Esata, a SPDIF out port and a PS2 combo port.

This is definitely a performance motherboard. It was meant for performance computing, supporting a massive 32GB of Ram, and 2-Way Crossfire and SLI. This is a great choice for the PC Gamer on a budget. It supports all AM3 and AM3+ Processors.

This motherboard would best be paired with an Eight Core processor and a HD 7970/GTX 680 in my opinion.
This is also a great motherboard for the overclocker, and is very good at achieving high overclocks that cheaper motherboards cannot sustain.


This is a solid motherboard. It's great for overclocking, It supports a wide variety of CPU's, Ram and Graphics card configurations.
It isn't that expensive either. This is certainly on my recommended list.


Pros: Lots of top-tier features. AMD FX-Series support AND AM3 Legacy Support.

Cons: BIOS takes a while to let you use the machine. BIOS can be sluggish, No EFI, BAD OVERHEATING!!!!

Despite all of it's many features, like On/Off USB charge, USB3, ErP, SATA3, and "Hybrid EFI (READ: NOT EFI), I have had some frustrating issues with this board. So without further ado, here are my issues in an outline form to make everything easily distinguishable:

☼ BIOS takes a LONG time to load into, and then is not EFI, but Gigabyte's "Hybrid" EFI. -__________-.
☼ When you want to just boot to your OS, it takes FOREVER (10~30 seconds) for it to boot to your OS.
☼ Sometimes, at seemingly random intervals, will not boot to the OS.
☼ Sometimes, at seemingly random intervals, will not go into the BIOS.
☼ Without additional cooling and NB at 2600mhz, the NB will get to VERY HIGH TEMPERATURES! (75~95c Idle~Load).
☼ System becomes VERY unstable without additional cooling of the NB at frequencies above 2300mhz.

So there you have it. I know there are some people out there with better experiences than me regarding this board, but I cannot recommend it to anyone until Gigabyte fixes the BIOS and overheating issues. Had I known how severe my experiences would be with this board, I would have held out for better hardware.



Pros: Sleek looking, Cheap, Plenty of PCI slots and USB slots.

Cons: Overheating due to bad VRM, Bios is lacking

I purchased this board from Gigabyte on the premise that it had ok reviews from Newegg and Amazon and it was at a reasonable price. If you do not plan on overclocking your CPU than this motherboard should do you fine if you are looking for a more budget friendly option. When overclocking my 8350 I experience voltage drops and extreme heat from the north bridge at just 4.2Ghz, was afraid to take it any higher than that. The heat sinks on the board are not attached very well and can be wiggled very easily from the board. The Bios isn't very intuitive with its overclocking options compared to other boards of this type. In conclusion, if you want to keep your CPU stock than its a great buy, If not please avoid this product.

I would definitely recommend the Asus Sabertooth 990fx rev 2.0 over this board. I'm currently at a 4.7ghz clock on it with ZERO voltage drops.


Pros: Lots of features, fairly good overclocker given the price

Cons: Lack of EFI( rev 1.1), LLC causes vboost

I got this board for a very cool 100$ on black Friday and I've been working with it since, trying to get a decent overclock out of my 1045T. This board overclocks fairly well, considering that I was able to get a 40%+ FSB overclock from my low binned Thuban. Personally I haven't had any problems with NB overheating at all, I have my NB at 2200mhz and it idles at ~30C which is respectable considering that the NB heatsink is very wobbly and is held in place by plastic-spring "locks" rather than nuts and bolts. I'd imagine that replacing the locks with bolts or screws should yield even better temperatures but I've not had a reason to do so. The motherboard posts fairly quick and the BIOS is your classic gigabyte bios; easy and simple.

The only negative point I can think of is LLC causing a fair amount of vboost, regardless of what setting I choose. Gigabyte needs to iron out LLC, but it's nothing deal breaking.

In conclusion, I think it's a great board board for the price. I can't talk about this board's overclocking limitations because I can only push my FSB so far. But it seems to run 280mhz FSB without a problem so I'd imagine that it would overclock like a champ with a multiplier unlocked CPU.

P.S - This review is for rev 1.1. I believe that the new rev 3.0 comes with a EFI bios and some other PCB improvements so it should be a fair step up from this board.


Pros: Good price, Great performance. Love the looks of the solid black board.

Cons: See other thoughts.

There are complaints of BIOS problem's and of overheating. Myself I have not had any issue with these. Its been a great board so far. I like the BIOS alot over my old ASUS board. I was on the fence about this board, or a Sabertooth board. Glad I got this one!
