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.

MSI Overclocking motherboards are equipped with all the necessary features to make sure you get the most out of your system. From the Enhanced PWM with a large amount of power phases and Thermal Design that give you the best stability, to all the easy features that ensure that you don't have to perform a lot of tricks to get great stability in your quest for performance.

DDR4
more speed, more bandwidth, less power
MSI engineers made sure you can enjoy high speed DDR4 compatibility.
DDR4 offers higher volume sticks, this means larger memory configurations are possible up to 128GB.

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.

OC Essentials
A small set of tools that are essential to get the best 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.

Optimized for multiple graphics cards
MSI Overclocking motherboards feature perfectly aligned PCI-Express 3.0 slots with enough space for an optimal airflow when using multiple graphics cards. That way, you will never have to worry about an overheating PC, while you are enjoying the best graphics jumping off from your monitor when running a NVIDIA® SLI™ or AMD CrossFire™ gaming setup.
CeaseFire Lite
When you are overclocking with LN2 and 4 VGA cards and simply want to benchmark using 3 or less VGA cards you don't have to physically remove one or more cards thanks to CeaseFire Lite, saving you a lot of time. With MSI CeaseFire Lite it is very easy to disable one of the PCI-E x16 slots with a simple switch in the BIOS.

Fast storage with SATA Express
SATA Express introduces a new solution in high speed storage through PCI-Express, providing more bandwidth for the latest generation SSDs up to 10 Gb/s.

Push your SSD even harder with TURBO M.2
Delivering speeds up to 32Gb/s using Gen3 x4, Turbo M.2 is more than 5 times faster than a regular SATA III connection! Enjoy a blazing fast system boot up and insanely fast loading of applications and games with MSI motherboards.
Next generation M.2
Turbo M.2 is the successor to M.2 10 Gb/s, offering 3 times more performance up to 32 Gb/s using Gen3 x4. M.2 is packed in a small form factor and is compatible with 3 different sizes to fit most storage solutions. All latest generation Intel® based MSI motherboards feature Turbo M.2 storage.

CPU Overcurrent Protection
When the MSI Overclocking motherboard detects a failure from hardware such as the CPU, it will shut down, prevent booting and protects other hardware from damage by disconnecting power to it. A red LED let's you know that overcurrent protection is active.

OC GENIE 4
We have implemented the revolutionary OC Genie 4 button with GAMING mode on our Overclocking motherboard series. Just press the OC Genie button on the motherboard and use the game switch and the system's game performance will be boosted.

GO2BIOS
Entering a BIOS can be a frustrating job. Because nowadays motherboards boot Lightning fast, we added the GO2BIOS button. Simply push it before you start or restart your system and you'll go straight to the system BIOS when your motherboard powers on.

Intel® Ethernet
Always connected with Intel® Gigabit LAN networking. Optimized for multimedia and gaming use to deliver a stable and fast network connection. Even when using LN2, to make sure you can upload your record-breaking scores.
