​​​​​​​MSI's X99A Gaming E-ATX Motherboard lets you create a Windows system armed with an Intel 5th-generation Core i7 processor, including the Extreme edition. It sports an LGA1151 socket and an Intel X99 chipset as well as eight DIMM slots that support up to 128GB of DDR4 memory. MSI has outfitted this motherboard with technologies to offer USB 3.1 with 10 Gb/s speeds and quad-channel memory compatibility. Other notable features include an M.2 slot and a U.2 adapter to handle the fast reads and writes of PCI-based SSDs. Furthermore, the onboard 802.11ac Wi-Fi and two Gigabit Ethernet ports provide a max throughput as high as 2.867 Gb/s, utilizing Killer's Network manager.

This X99 motherboard comes with features so you can build a 3D gaming machine. With an extended-ATX form factor, it's able to provide five PCIe 3.0 x16 slots so you can link your dedicated graphics cards with NVIDIA SLI or AMD Crossfire technology. To complete your multimedia experience, Audio Boost 3 Pro and Nahimic Sound technology surround you in sounds from the motherboard's six audio ports and 6.2mm audio jack. For enhancing overall performance, you may overclock your processor, memory, and graphics with the OC Genie 4 button or Click BIOS 4.

MSI has designed this motherboard with Bluetooth that connects to speakers and headsets wirelessly. Aside from wirelessly connectivity, one of the two USB 3.1 ports features a Type-C interface that lets you connect on the first try. There are also ten SATA III 6 Gb/s and four USB 3.0 ports along with a single PS/2 keyboard/mouse combo port built onto this motherboard.

Intel X99 Express Chipset

The X99 Express chipset is designed to utilize Intel's 5th-generation of Core i7 processors, including the Extreme edition. It delivers RAID support and ten SATA III ports so the system can protect and quickly access data. This chipset natively supports up to fourteen USB ports as well as forty PCIe 3.0 lanes for faster data retrieval. For memory capabilities, 128GB of DDR4 memory modules can be installed.

Intel LGA2011 v3 Socket

This motherboard supports 4th and 5th-generation Intel Core i7 processors in the LGA2011 v3 package. These processors can come with up to 8 cores and 40 PCI lanes as well as a quad-channel memory controller.

DDR4 Memory

The eight DIMM slots enable you to build a system with up to 128GB of DDR4 memory modules, which offer high memory speeds at low power usages of 1.2V. In addition, quad-channel memory support delivers more memory bandwidth than a dual-channel design.

Mystic Light

This motherboard comes with LED lighting that can be controlled with the Mystic Light app. You can select any of the colors from the palette to match your systems' design. Moreover, it comes with effects to personalize the inside of your case further.

Killer DoubleShot-X3 Pro

Killer DoubleShot-X3 Pro configures the two onboard Killer Ethernet controllers and the Killer Wi-Fi adapter to work together. With Killer Network Manager software, you can assign apps to run on a specific connection to prioritize the network traffic.

Audio Boost 3 Pro

With premium audio components powered by Nahimic sound technology, this motherboard offers studio-grade sound by delivering clear sound and music through 8-channel speakers or high impendence headphones. Audio is enhanced with Nahimic sound technology. This motherboard comes with six audio jacks, Chemi-Con audio capacitors, and two headphone amplifiers as well as an isolated audio PCB, EMI-shielded audio processor, ESS ES9018K2M DAC, AMP switch, 6.35mm headphone-out jack, and front headphone-out connector.

Overclocking Technology

MSI has equipped this motherboard with overclocking features that can be controlled via software or hardware. It comes with OC Engine that is a clock generator, which overclocks your setup and offers lower jitter and power consumption. It's built with multiple PCB layers and copper heatpipes as well as a DigitALL PWM controller, overcurrent protection, OC thermal design, DirectCU+, and OC socket design to support heavy overclocking. The X99A has OC Essential that is a set of tools to ensure you get the best from your components. These tools provide on-the-fly overclocking and assistance in trouble shooting with the following features:

• OC Genie 4 Button - automatically enhances the processor and memory by up to 20%
• Easy Button 3 - illuminated buttons lets you reset, power up, or power down the system
• Debug LED - a two-digit panel for diagnostics and CPU temperatures
• V-Check Points 2 - supports up to three multimeters at once to accurately monitor the voltages
• Clear CMOS Button - resets the BIOS' settings
• MultiBIOS II - a switch and LED light lets you change between the two BIOS chips

Protection

MSI has provided circuit protection for this motherboard by outfitting it with a super ferrite choke, Hi-c and Dark capacitors, multiple PCB layers, and shielding along with a DrMOS mosfet. For key components, they have passed military testing to ensure stable operation in a harsh environment. MSI has protected all the I/O ports on this motherboard against electrostatic discharge damage. With the increased size and weight of high-end graphics cards, MSI has designed the PCIe slots with reinforced soldered points that help strengthen the connection. In addition, the motherboard meets FCC regulations and produces less electromagnetic interference than other motherboards.
