MSI 990XA-GD55 AMD 990X (Socket AM3+) Motherboard overview

CPU and Chipset Features



AMD (AM3+) FX Series Processors
This motherboard supports latest AMD Socket AM3+ multi-core processors with up to 8-core native CPU cores and delivers better overclocking capabilities with less power consumption. It features AMD Turbo CORE Technology 2.0 and accelerates data transfer rate up to 5200MT/s via HyperTransport 3.0 based system bus. This motherboard also supports AMD CPUs in the new 32nm manufacturing process.

AMD 990X Chipset
AMD 990X 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.

Performance and Stability Features


Military Class II - Hi-c CAP
8X the Lifespan of a Solid Capacitor!! Insisting on the best stability, MSI utilizes Hi-c CAPs on their Military Class series motherboards. Made of the rare element Tantalum, often used on space shuttles and satellites, which sustains very high temperatures and shows an amazingly high electrical conductivity.

Military Class II - Super Ferrite Choke
The Super Ferrite Chokes (SFC) use a Ferrite core that is Super-Permeable. Compare with a traditional choke, the Super Ferrite Chokes run at a 35 degree Celsius lower temperature. The lower working temperature will enhance mainboard stability.

Military Class II - Solid CAP
10 years long lifespan. For providing the highest quality products, MSI built-in Solid CAP in the entire Military Class series. This not only makes bursting capacitors a non-issue but also ensures a dramatically extended lifetime and ultra-low ESR.

Active Phase Switching (APS)
Active Phase Switching (APS) technology is an intelligent design that helps to save energy on MSI’s mainboards. The underlying idea is to switch off the power supply as soon as no electricity is needed, and when the system needs more resources again, APS will automatically adjust electricity supply accordingly. APS will automatically detect your processor’s loading at any given time and save energy accordingly. This is only possible by means of a very advanced power controlling technology. Other than software-based solutions, APS technology stands out from MSI's own research. The specially developed IC chip can operate automatically depending on the demands of the power supply, which is to reduce the total power usage.

OC Genie II - Overclock & Unlock CPU Core in 1 Second
OC Genie II, the most powerful and easy overclocking technology is implemented on MSI's AMD 9-Series mainboards. MSI's OC Genie II completely automates advanced overclocking functions and offers up to 248% higher performance with the simple click of a button. It does not matter if you're a first time hardware owner, or a veteran overclocker, activating MSI OC Genie II will unlock your hidden CPU cores, overclock your CPU and your memory to simply give you the best and most stable performance for free on MSI AMD 9-Series mainboards.



DrMOS
With its 3-in-1 combined design and special circuity, the DrMOS solution can drop the motherboards temperature by up to 16C when compared similar motherboards with a more traditional MOS solution. This temperature drop helps extend the life of the board and brings increased stability when overclocking. DrMOS also combines the IC, bottom MOSFET and TOP MOSFET to make a smoother faster transfer of electricity across the board. The result is improved performance when compared to traditional decentralised MOS designs.

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 a 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.

Memory Features


Dual-Channel DDR3 2133(OC) MHz support
The motherboard supports a maximum of 32GB DDR3 memory that features data transfer rates of up to 2133(OC) MHz to meet the higher bandwidth requirements of the latest 3D graphics, multimedia and Internet applications. The dual-channel DDR3 architecture enlarges the bandwidth of your system memory to boost system performance.

Audio Features


Lossless 24-bit/192KHz HD Audio
Onboard PC audio gets better! MSI is the first to implement the most high-end HD Audio codecs available. Don’t be fooled by other inferior audio solutions onboard (sometimes you can’t even find the driver!) Only MSI offers the Loss-less 24-bit/192KHz HD Audio function with an incredible 109 SNR dB value to provide the most clear & vivid HD audio quality and support 7.1 channels surround sound playback with a 2-channel independent stereo output (multiple streaming) through the front panel 3.5 inch phone jack.

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 mainboard 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 to break the existing bottleneck of a PC’s performance.



USB 3.0
Compared to the 480Mbps provided by traditional USB 2.0, the all-new USB 3.0's 5Gb/s offers 10 times the transfer bandwidth, so transferring a Blu-ray movie takes less than one minute. MSI also has implemented a front panel USB 3.0 port, making the use of an external USB 3.0 device even more convenient.

Super Charger
Mobile consumer appliances are getting more and more attention in the current day fast moving life style, with smart phones and tablets almost becoming a fashion accessory. However, many ordinary personal computers cannot charge some of these devices, making it difficult to stay connected. The MSI Super Charger is a Windows resident program capable of revising the power supply mode of your USB port to become more powerful. Once your phone or tablet is connected to your USB port, the Super Charger sends a signal to initiate its charging circuit, making it a really smart and convenient charging solution for mobile computing needs.

USB Safeguard
USB Safeguard can prevent mainboards and USB devices from being damaged by short-circuit and ESD (Electro-Static Discharge) with Anti-ESD chips built-into the mainboards. Additionally, the safeguard can protect against such dangers multiple times, and greatly improves product lifespan.

Software and Bios Features


M-Flash
Compared to the common mainboard which needs extra BIOS chips, MSI’s M-Flash has a double advantage. Firstly it doesn’t need extra components and secondly all your BIOS data will be saved in the USB drive. The stored data does not only have backup and upgrade function, moreover it can also be seen as a portable BIOS chip which is actually able to boot up your PC.

3TB+ Infinity
3TB+ Infinity is not only breaking through the limit of the traditional BIOS, but also enhancing the utilization of a hard drives efficiently. In addition to supporting the latest 3TB hard drives, MSI 3TB+ Infinity technology can use the 3TB hard drive as boot disk when installing a 64-bit operating system. Compared to competitors, MSI 3TB+ Infinity is an industry-leading technology which substantially presents an advantage of development and application in the future.

Winki 3
Winki 3 is a free Linux-based O/S which is based on the Linux core. With an ultra-fast booting speed and a multi-language interface, the built-in Winki 3 provides an easy-to-use internet environment that includes the most popular functions such as internet surfing, web mail, instant messaging, picture browsing, and more. It's the most practical way to be online in the shortest time.



Live Update Online
