CPU and Chipset Features

Intel Core i7 Extreme Processors

Intel Core i7 Extreme Processors offer you unbelievable power that encourages you to become the digital content creator or gamer you always wanted to be. Need cores to render? Check. Need cores to compile? Check. Need cores to seek and destroy in the latest game? Check. It seems almost unfair to add Intel Hyper Threading Technology for up to a total of 16 threads at your disposal. You want burst speed performance for those jobs that require a bit more frequency? Intel Turbo Boost Technology has that covered. But that little voice inside of you is saying you want even more? Let that voice know that the processor is unlocked and is ready for you to tune it to fit your demanding needs. Tune cores, power, memory, or whatever else you need to tune to make your system fit your needs.

Intel X99 Express Chipset

With up to 40 PCI Express (PCIe) Gen3 lanes, 10 SATA Ports, 14 USB Ports and 20MB Smart Cache, the X99 chipset offers maximum I/O capabilities and storage features for the most demanding users. The high-speed I/O interface delivers blazingly fast performance and expandability. Intel Rapid Storage Technology delivers new storage performance and other capabilities which allows for improved platform responsiveness. The extensive I/O, couple with massive storage and better responsiveness, offers the end user a high-end and exclusive PC experience.

Performance and Stability Features

Military Class 4

MSI's Military Class 4 components support you while you are questing, racing, battling and shooting your way to the top. MSI's Military Class 4 components deliver record-breaking stability when you need to keep cool in the heat of battle. The new standard in stability built on a proven technology of high quality components. Super Ferrite Chokes use a Ferrite core that is Super-Permeable. This allows the Super Ferrite Chokes to run at a 35 degree Celsius lower temperature, have a 30% higher current capacity, a 20% improvement in power efficiency and better overclocking power stability. With their aluminum core design and Japanese made quality, Solid CAPs are made for high-end design motherboard. Not only do Solid CAPs could provide lower Equivalent Series Resistance (ESR), but also work firmly for over-10-year.

Guard Pro

MSI's Guard Pro is a collection of technologies to ensure motherboard stability and longevity even under the most extreme gaming conditions. Carefully selected materials, multiple PCB layers and shielding result in the best circuit protection for our motherboards. 10% Reduction in moisture absorption helps prevent "Conductive Anodic Filament". Untreated PCB's can have 10x higher failure rate. All key components used in MSI motherboards have all passed military testing ensuring stable operation in the harshest environments. Each and every I/O port is protected against the hazards of Electro Static Discharge. With MSI ECO Center you can physically cut the power to unused chips to save up to 29% power usage.

OC Genie 4

OC Genie is the world's first built-in hardware overclocking technology on motherboards. With this one-second overclocking option we're giving you even more performance. Just hit the button and your PC gets another adrenalin shot. Delivering up to 20% of free extra performance for the CPU, memory and iGPU.

OC Engine

Run into unstable situations when pushing your CPU to the limit? This occurs because the internal clocks are linked through the 100 MHz BCLK strap. Thanks to a integrated Clock Generator, MSI motherboards support more flexible BCLK adjustments, from 100 / 125 / 167 MHz straps. Using these straps prevents system crashing while overclocking on the edge and opens doors to achieve the absolute maximum. The MSI X99 motherboards all come with the next generation Clock Generator offering even lower jitter and power consumption resulting in even higher stability under extreme conditions.

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.

Memory Features

Quad-Channel DDR4 Support

The motherboard supports up to 64GB DDR4 memory via 8 Memory Slots. Featuring stock frequencies starting at 2133 MHz, DDR4 delivers up to 20% less energy consumption and twice as much density as the previous generation DDR3.

Transfer Features
