In July of 1969, Apollo 11 supposedly landed on the moon. Why do I say “supposedly”? Well, there has been a lot of conjecture as to whether or not it actually happened, and seeing the same small rock formation in photos from two different landings put some doubts in mind. But, we aren’t here to discuss conspiracy theories, after all, they are probably reading this right now and gathering outside to break through one of my windows with tear gas and stun guns…..or I merely want to acknowledge those who believe it may not have happened. I’ll leave it to you to figure out which. Either way, we can pretty much all agree that Neil Armstrong did, in fact, say “one small step for man, one giant step for mankind” when he (supposedly) took man’s first steps on the moon. Though I still wonder why we spent all that money going there in the first place…..



The point of this being, it sometimes takes small steps to become giant leaps. Those anxiously awaiting Bulldozer are already primed for it to be a giant leap. As to whether it will be in the performance category, only time will tell, but in the world of architecture, it is certainly a giant leap right from the start. The thing is, AMD has always been very customer loyal and backwards compatible friendly, so how do you make this leap and retain that stance? One answer is the newly unveiled 990 chipsets, which are capable of handling Bulldozers AM3+ socket, but still retain full AM3 compatibility. So, again, AMD offers the option to upgrade one small step at a time. Based off the 890FX and sharing the 950SB South Bridge, the 990FX is a small step on the noticeable feature end from the 890FX in most cases. On a couple of boards we have seen, SLI support has been added for up to four cards and CrossFire-X support has been upped to four cards across the board. For the serious gamer, this would certainly be a larger step. But, in the end it’s the giant leap into Bulldozer that is the main attraction here.


Gigabyte is coming out of the gate with the GA-990FXA-UD5 AM3+ Motherboard. The Gigabyte GA-990FXA-UD5 AM3+ Motherboard is feature rich and Bulldozer ready, but is still fully compatible with existing AM3 processors. Featuring amenities such as USB 3.0, 8 SATA III connections (with 3TB support), PCIe slots capable of three way CrossFire-X or SLI, and onboard HD audio, the GA-990FXA specs like an enthusiast's dream. Opening the box and finding an all black design with gunmetal heatsinks, the GA-990FXA-UD5 also LOOKS like an enthusiast's dream. The GA-990FXA-UD5 retains Gigabytes most sought after features – Ultra Durable 2oz copper design, Dual BIOS, which almost nullifies the chance of BIOS failure, On/Off Charge and Driver Mosfet VRM technology. Included software includes Gigabyte’s Easy Tune 6 for hardware monitoring, overclocking and tweaking, Cloud OC for remote overclocking and Auto Green, which can link to a Bluetooth cell phone and put the computer to sleep when the phone loses its link. With the GA-990FXA-UD5, Gigabyte presents a strong package of features in a very nicely designed motherboard.

Coupled with AMD’s highly efficient processors, the Easy Energy Saver is able to provide exceptional levels of power savings and enhanced power efficiency without sacrificing computing performance.



GIGABYTE has completely redesigned EasyTune6 from the ground up to make it easier than ever to manage and monitor your hardware resources as well as tweak your system settings in order to achieve maximum system performance. Whether you are an overclocking enthusiast, or a computer novice, EasyTune6 provides the tools you need to quickly and effortlessly fine tune your system.


Gigabyte’s EasyTune 6 offers great control and monitoring for your motherboard and components. The CPU status screen gives all relevant status information for your current CPU state, while the Memory tab does the same for your RAM. The “Tuner” tab offers access to all basic OC options, including multiplier, FSB and voltages while also offering core unlocking from the software end. The “Graphics” tab allows for core speed and memory speed adjustment and OC of your installed video card. ET6’s “Smart” tab is not for your HDD status (S.M.A.R.T) as one might assume. The “Smart” tab is using for programming fan speed at varying temperatures to achieve the balance you desire of performance and silence. Note that CPU Smart Fan must be enabled in the BIOS for this feature to operate. Finally, a voltage and temperature monitor give a full picture of the current status. It is worth noting (and can be seen here) that changes made with AOD are not reflected in ET6’s status monitors. Looking at the difference in “Power On” and “Target” of the multiplier and CPU voltage, you can see that multiplier and voltage were both increased with AOD, but are not reflected in the read speed of the CPU.

Performance Tuning (Overclocking)

The Gigabyte GA-990FXA-UD5 comes bundled with the latest incarnation of Gigabyte’s Easy Tune 6 software. In addition to hardware monitoring, it offers the “Easy Boost” overclocking feature for simple, one click overclocking. Simply hit the Easy Boost button and Easy Tune 6 does the rest, taking your build through a succession of speed bumps and stability tests to find a stable (and seemingly safe) overclock. The process took approximately 45 minutes on this build and could not have been simpler. Three attempts with Easy Boost yielded two results at 4.13GHz with a 1.44v, and one at 4.2GHz at 1.45v. That is a pretty impressive OC for a simple one click, and these speeds are certainly stable. A quick look at the final parameters showed that the 4.2GHz result was only a raise of the multiplier, while the 4.13GHz included a slight bump to the FSB.



Tweaking the GA-990FXA-UD5 by hand, of course, produced slightly better results. Raising the multiplier to 22x and voltage to 1.475 off the bat produced no problems booting at 4.4GHz. This was exactly the OC used on this particular 980BE previously in an 890GX MB. There were stability issues running OCCT and Prime 95 after several minutes, with core errors appearing. Bumping the core voltage and NB VID slowly, stability was achieved at 4.4GHz, with a final CPU voltage of 1.52v and NB VID of 1.24.

I attempted to OC by raising the FSB, but had no luck with this particular RAM and processor. Dropping the multiplier on the RAM did not help, and a FSB over 202 was not stable. I don’t see this as a reflection on the GA-990FXA-UD5’s capabilities, as I have had exactly the same results on three other motherboards, one being a Gigabyte and two from other top name manufacturers.

The Gigabyte GA-990FXA-UD5 offers very good overclocking potential. The inclusion of Easy Tune 6 lets even the most novice of users obtain a good OC while keeping the system stable. For the more advanced, the wealth of BIOS features makes tuning and tweaking exploration quite easy, while the GA-990FXA-UD5’s stability allows for unlocking the full potential of your CPU.

Performance of the Gigabyte GA-990FXA-UD5 was excellent across the board. All drivers worked flawlessly on first install with no tweaking necessary. The BIOS of the GA-990FXA-UD5 offers excellent options and flexibility. USB 3.0 and SATA speeds exceeded expectations, with USB 3.0 being easily used for a boot device. PCIe speeds were as expected from an FX series board. The final OC achieved was what was expected from the processor, though voltage required was somewhat higher than expected.

Reviewer's Opinion

Straight out of the box, the Gigabyte GA-990FXA-UD5 lets you know that it is a serious motherboard design, and one that was executed well. The design is sleek and attractive, with great attention to detail. One may ask what looks matter in a motherboard, but the point is the execution. The parts aren’t flimsy, tolerances are exact and attention to assembly is flawless. That is what makes the Gigabyte GA-990FXA-UD5 so attractive. When you look at it and pick up the GA-990FXA-UD5, you know immediately that you are handling a top quality piece of equipment.

Getting into the board’s features, I was left wanting for nothing, and all of the features worked exactly as advertised. Tri-Sli and three way CrossFire-X are sure to keep gamers happy, as will the much better than average integrated 7.1 audio. Enthusiasts will certainly appreciate the great overclocking headroom and wealth of BIOS options for tweaking. Just about all will appreciate the upgraded USB 3.0, 8 SATA III ports and powered eSATA. And, of course, iPeople will appreciate On/Off Charge to keep their iStuff charged even when the computer is off. The Gigabyte GA-990FXA-UD5 is a feature rich board that should satisfy the needs of anyone planning on using less than four video cards.

Aside from the obvious, there were some really pleasant surprises that came with the GA-990FXA-UD5. The included Easy Tune 6 software is a truly nice program for novice overclockers to get their feet wet with. I was impressed with the one click OC achieved, which was only a few ticks off from what I could achieve when keeping the voltages in what AMD considers a safe zone. More than that, it enables you to see the changes made, enabling a novice to begin getting an understanding of what is going on, rather than having the Wizard of OZ behind a curtain. Kudos to Gigabyte for pairing this with the GA-990FXA-UD5 that clocks well to begin with.

The other nice surprise was increased read and write speeds on the GA-990FXA-UD5 from my 890 boards. Read speeds in HD Tune jumped a full 10MB/s from 92 to 102 with no change in any hardware excepting the MB. This was totally unexpected, as no mention of a tweak to this was made.

The one and only downside was the extra voltage I needed to put into the 980BE to get to 4.4GHz in the GA-990FXA-UD5. It took 1.52v to get the chip stable. Previously this mark had been achieved at 1.475v on other 790 and 890 boards. The jump in voltage also brought with it the natural jump in temperatures, both to the CPU and system. Temps were not out of control, but a little warmer than I would have liked to have seen.

There is no disputing that the Gigabyte GA-990FXA-UD5 is an absolute top of the line motherboard. The GA-990FXA-UD5 is packed with features, all of which work absolutely flawlessly. Build on the GA-990FXA-UD5 is solid, with great finish and attention to detail. The included Easy Tune 6 utility works extremely well as an overclocking utility for the novice, as well as being a very capable hardware monitor and fan speed controller. With the Gigabyte GA-990FXA-UD5, you get an extremely capable and feature rich motherboard, all wrapped in one very attractive sleek black package. The GA-990FXA-UD5 is highly recommended.
