GIGABYTE GA-990FXA-UD3 AMD 990FX (Socket AM3+) ATX Motherboard overview

GIGABYTE Ultra Durable Series

GIGABYTE Ultra Durable Series motherboards feature a range of technologies designed to improve the performance, stability and longevity of your motherboard.

Processor and Chipset Features

AMD FX / Phenom II / Athlon II / Sempron 100 Series Processors

This motherboard supports AMD AM3+/AM3 multi-core processors with unique L3 cache and delivers better overclocking capabilities with less power consumption. It features dual-channel DDR3 memory support and accelerates data transfer rate up to 4800MT/s via HyperTransport 3.0 based system bus. This motherboard also supports AMD CPUs in the new 32nm manufacturing process.

AMD 990FX Chipset

AMD 990FX Chipset is designed to support up to 5.2GT/s HyperTransport 3.0 (HT 3.0) interface speed and dual PCI Express 2.0 x16 graphics. It is optimized with AMD latest AM3+ and multi-core CPUs to provide excellent system performance and overclocking capabilities.

Memory Features

Dual-Channel DDR3 2000(OC) MHz Support

The motherboard supports up to 32GB DDR3 memory that features data transfer rates of 2000(OC) MHz to meet the higher bandwidth requirements of the latest 3D graphics, multimedia and Internet applications.

Motherboard Size


This motherboard is an ATX motherboard with the dimensions of 30.5cm x 24.4cm. It will fit in any case that supports motherboard sizes of ATX or higher such as a Mid Tower case or larger.

Transfer Features

SATA 6Gb/s

SATA 6Gb/s provides double the bandwidth of traditional SATA 3Gb/s, and increases the data transfer rate between your motherboard and internal storage devices, such as 7200RPM HDDs, 10000RPM HDDs and SSDs. It's also the current trend for upcoming high-speed internal storage devices to break the existing bottleneck of a PC's performance.

External SATA

The external SATA port located at the back I/O provides smart setup and hot-plug functions. Easily backup photos, videos and other entertainment contents on external devices.

USB 3.0 5Gb/s

Compared to the 480Mb/s provided by traditional USB 2.0, the new USB 3.0's 5Gb/s offers 10 times the transfer bandwidth, so transferring a Blu-ray movie takes less than a minute.

Graphics Features

AMD CrossfireX Multi-GPU Support

AMD CrossFireX is the ultimate multi-GPU performance gaming platform. Enabling game-dominating power, AMD CrossFireX technology enables two or more discrete graphics processors to work together to improve graphics performance. AMD CrossFireX technology allows you to expand your system’s graphics capabilities. It allows you the ability to scale your system’s graphics horsepower as you need it, supporting up to four AMD Radeon HD graphics cards, making it the most scalable gaming platform ever. With an AMD CrossFireX gaming technology, the traditional graphics limitation exists no more, allowing you to enjoy higher performance as well as visual experience.

NVIDIA SLI Multi-GPU Technology

NVIDIA SLI technology is a revolutionary platform innovation that allows you to intelligently scale graphics performance by combining multiple NVIDIA graphics solutions in an SLI-Certified motherboard. Using proprietary software algorithms and dedicated scalability logic in each NVIDIA graphics processing unit (GPU), NVIDIA SLI technology delivers up to twice the performance (with 2 cards) and 2.8X the performance (with 3 cards) compared to a single graphics solution.

The only problem I've had is getting the correct Dolby drivers for the onboard sound. I have a separate creative labs sound card so its not that much of a biggy. Otherwise, nice board. Does what its supposed to do

I have had this board now for the last 12 months and it has worked flawlessly. It's fantastic at what it does and was worth every penny. The board arrived with the latest BIOS. I phone Novatech support before purchasing to inquire about the BIOS and the CPU I'm using and they were most helpful.

I bought this board because I was looking to downgrade but still wanted sufficient ability to do most things. I wasn't disappointed. It was easy to install, looks good and not to technical. Really pleased. The price was very good to. I have bought lots of things from Novatech and I have never been disappointed. They are always there to give advice and support. Keep it up.

Great looking board, had a bit of a problem installing drivers first hand as the drivers on the disk that came with it were only windows 7 drivers so I had to wait for the windows 8 ones. Love the super charging ports on the board that can charge usb devices when the computer is turned off, they come in handy! My only problem is that when I set my 1600mhz corsair vengance ram to 1600mhz in the bios (which isnt uefi, dont know why it didn't come with a uefi bios when it said it did) because the bios automatically sets it to 1333mhz my system wouldn't boot up windows so im stuck at 1333mhz. Great board anyway, highly recommend, especially as its the cheapest board I found with a 990fx chipset and usb 3.0 internal header.

One thing that makes this board a winner is the internet connections, I downloaded their internet diognostic utilties ive twined my internet conections, wow high speeds great reliability.

Everything is spaced so nicely on this motherboard oodles of room, the Sata connectors are a bit fiddly as they are facing horizontally from the motherboard so best to connect them first and lower the board into your case.
