Performance
OC Certified
OC Certified is a military class burn-in test for motherboards. Running Prime95 for over 24 hours with a highly overclocked CPU is already a stressing endeavor, but removing all airflow from the motherboard ensures that only the best motherboards survive. If a motherboard can survive this, it can survive any overclocking situation. This motherboard is equipped with the necessary features to make sure you get the most out of your system. These features include enhanced PWM with a large amount of power phases and Thermal Design that give you optimal stability.
OC PCB
The OC PCB used for the overclocking motherboards has a unique design in which 50% more layers are used compared to standard motherboards. This allows us to optimize all traces for overclocking. Power and signal traces are isolated, resulting in higher efficiency and performance, and more features can be installed relatively close to each other, without causing interference. This motherboard is tuned for better stability under optimal circumstances such as increased number of PCB layers, increased humidity resistance, tight weave Fiberglass PCB, and increased ESD protection.
DigitALL Power PWM
DigitALL Power digitally steers and receives feedback through a DigitALL PWM controller. This allows for pinpoint voltage delivery and lower power consumption.
Thermal Design
XPOWER Thermal Design was developed to deliver optimal cooling potential in the worst situation. It is optimized to work in low-airflow situations, so, it's a suitable cooling to use with liquid cooling setup. The cooling solution features XPOWER thermal design, SuperPipe, low-airflow, optimized design, clear CPU space, and metal screws.
OC Socket Design
The motherboard has a lot of space around the socket that helps you to fit any cooling solution you want. It makes it easier to insulate the motherboard for use with LN2 or other extreme cooling solutions.
OC Backplate
OC backplate is a low profile backplate which is flat and gives full access to the screw holes needed to mount your cooling solution. It generates optimal mounting pressure. This leads to lower CPU temperature and maximizes overclocking results. You can also combine the OC Backplate with the MSI Delid Die Guard for even better mounting and cooling results.
DDR4
You can experience high speed DDR4 compatibility. DDR4 brings higher memory speeds at even lower power usage as low as 1.2v.
DDR4 offers higher volume sticks; this means larger memory configurations are possible up to 128GB.
Protective I/O Cover
A black design I/O cover with OC series imprinted protects against Electro Magnetic Interference. Making sure whatever device you connect, you will always receive a pure signal.
OC Engine
Unstable situations when pushing your CPU to the limit occur because the internal clocks are linked through the 100 MHz BCLK strap. Integrated Clock Generator enables the motherboard to 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 motherboard comes with the next generation Clock Generator offering even lower jitter and power consumption resulting in even higher stability under extreme conditions.
Delid Die Guard
The MSI Delid Die Guard helps with air, water or subzero overclocking activities. This mounting system makes it easier to mount a delidded CPU and helps to achieve lower CPU temperatures, making sure you can squeeze every MHz out of it. Delid Die guard helps to lower CPU temperature and is an easier and more stable fitting of cooling solution. It protects the die of your CPU, and also generates optimal mounting pressure.
OC Fan Stand
The OC Fan Stand allows you to you easily set up your fans while overclocking without worrying about them falling over. A sturdy and easy to use design makes setting up fans easier.
OC Essentials
It's a small set of tools that are essential to get optimal performance out of your motherboard. These features increase stability, assist in trouble shooting, allow you to keep your complete system in check, and allow for simple management. This way you can keep your mind on overclocking.
Slow Mode
Slow Mode helps to defeat booting issues when overclocking at high CPU frequencies. Flicking the switch will temporary decrease CPU ratio to 12x, creating stability to successfully boot to Windows.
OC Genie 4
OC Genie is a built-in hardware overclocking technology on motherboards. It allows one-second overclocking by simply pressing the OC Genie button. OC Genie 4 has the ability to switch between two gears.
Direct OC
A set of '+' and '-' buttons allows you to adjust your Base Clock in real time, even during benchmarking. The Direct OC software allows you to select 1 MHz or 0.1 MHz increments. The XPOWER AC allows for better control because it is equipped with a switch on the motherboard, which allows you to make the 1 MHZ or 0.1 MHz increments. On top of that it also comes with two extra Direct OC buttons to increase the multiplier ratio. It has buttons such as BLCK up, BLCK down, Multiplier up, and Multiplier down.
Complete Discharge
Holding this button for two seconds completely wipes your motherboard from all settings. The CLR CMOS button only limits itself to the BIOS/VRAM but this Complete Discharge button removes information from the X99 PCH.
Direct USB
Direct USB allows for faster and more convenient ways of saving scores, flashing the BIOS, and installing drivers and software when overclocking on an open test bed. The Direct USB connector also allows for easy pre-testing of your hardware prior to installing it in a PC case.
V-Check Points 2
After MOA feedback we enhanced the V-Check Points with two extra ground connectors. This way overclockers can use three multi-meters at the same time. Do not use CPU-Z to measure voltages. The increased switching frequencies and incompatibilities lead to large deviations. (VCCIN: CPU input voltage, DDR01: Memory voltage - Channel A/B, DDR23: Memory voltage - Channel C/D, VPP01: Memory VPP voltage - Channel A/B, VPP02: Memory VPP voltage - Channel C/D, Core: CPU core voltage, GND: Ground, GND: Ground, GND: Ground)
4-Way SLI/CrossFire
POWER AC motherboard supports 4-way SLI/CrossFire. Optimal PCIe slot placement allows for better fitting and airflow. That way, you can experience optimal graphics at high frame-rate jumping off from your screen, when running an NVIDIA SLI or AMD CrossFire setup.
CeaseFire
When you are overclocking with LN2 with four VGA cards and want to switch to three or two cards you normally would have to remove the cards. However, with the LN2 pot on the motherboard and all the insulation, removing the card can be a big hassle. With MSI CeaseFire, it is very easy to disable one of the PCI-E x16 slots using an onboard switch without the need of removing the cards.
SATA Express
SATA Express with PCIe provides greater bandwidth for the latest generation SSDs up to 10 Gb/s.
Turbo M.2
