Performance and Stability Features

GIGABYTE Ultra Durable 4

GIGABYTE Ultra Durable 4 motherboards embrace a range of exclusive technologies that guarantee DIY PC builders the absolute best protection for their PC, with built-in features that prevent common malfunction threats.

Driver MOSFETs - Integration of VRM Components

A traditional Voltage Regulator Module (VRM) consists of a Choke, Capacitors, MOSFETs and a Driver IC. By incorporating the MOSFETs and driver IC in accordance with the Driver-MOSFET specification, we can achieve higher power transfer and increased efficiency at higher switching frequencies to satisfy the growing power requirements of today's processors. Driver-MOSFETs also help to reduce VRM real estate requirements in the CPU zone.

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.

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.

Memory Features

Dual-Channel DDR3 2000+ MHz Support

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

Audio Features

108dB Signal-to-Noise ratio playback

GIGABYTE motherboards feature higher capability audio solution with 108dB Signal-to-Noise ratio (SNR) playback quality to deliver high-performance, multi-channel HD audio. SNR is a comparison of the amount of signal to the amount of noise such as hiss present in the signal (expressed in Decibels). A higher SNR equals a better audio experience. For example, 108dB, is a high audio specification, as this means the audio signal is 108dB higher than the level of the noise.

Dolby Home Theater Support

Delivers vivid surround sound for music, movies, and games, using two to eight speakers or any set of headphones.

Transfer Features

SATA 6 Gbps

Yet another onboard feature of GIGABYTE AMD 900 series motherboards are integrated the latest AMD SB950 chip for high-speed SATA Revision 3.0 compatibility, delivering 6 ports native superfast 6Gbps link speeds for twice the data transfer rates of SATA Revision 2.0 (3 Gbps) and RAID 0, 1, 5, 10 support. When used in RAID 0 (Stripe) mode, GIGABYTE AMD 900 series motherboards offer even faster data transfer rates of up to 4x the speed of current SATA interfaces.

USB 3.0 Support

The GIGABYTE motherboards support the latest generation SuperSpeed USB 3.0 technology made possible through an onboard USB3.0 host controller. With superfast transfer rates of up to 5 Gbps, users are able to experience an almost a 10x improvement over USB 2.0.

3x USB Power Boost

GIGABYTE motherboards feature a 3x USB power boost, delivering greater compatibility and extra power for USB devices. GIGABYTE’s unique USB power design is also able to efficiently regulate output over the full voltage range, which greatly enhances USB device compatibility. In addition, dedicated lower resistance fuses ensure lower voltage drops, and provide more stable and plentiful power delivery.

Power eSATA

Featuring two external SATA (Power eSATA) ports in the rear panel that provide smart setup and hot-plug functionality that allows easier data backup and content manipulation on external storage devices.

On/Off Charge Technology

GIGABYTE On/Off Charge technology allows you to charge your iPhone, iPad and iPod Touch regardless of whether your PC is on, in standby mode or even off.

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

Review Star Review Star Review Star Review Star Review Star



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.

Review Star Review Star Review Star Review Star Review Star



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.

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.
