OC Essentials

RECORD AND STREAM ALL OF YOUR IN-GAME ACTIVITY WHILE ENJOYING YOUR GAMES AT MAXIMUM FPS
Because X99 lacks an integrated GPU, Intel Quicksync is no longer available to help while streaming your gaming activity. MSI Streaming Engine captures video real-time through a dedicated hardware solution making sure you are free of any impact on CPU performance, where other solutions demand vital resources highly impacting FPS performance.

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.

DDR4 MORE SPEED, MORE BANDWIDTH, LESS POWER
MSI engineers made sure you can enjoy 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.

REWARD YOUR EARS WITH TRUE QUALITY
Get ready for ear-drum shattering sound, with MSI Audio Boost 2! With Audio Boost 2 we're delivering the highest audio quality with the use of Creative Sound Blaster Cinema 2 so you can enjoy crystal clear sound and music through 8-channel HD Audio.

ISOLATED AUDIO PCB
With traditional onboard audio the signal is distorted by electromagnetic signals from the rest of the PCB. Audio Boost 2 acts like a dedicated soundcard by physically isolating the audio circuitry which is separated by a red LED path. Less interference gives you a more clear audio signal.

DIRECT AUDIO POWER
Enjoy a heavy caliber audio experience with Direct Audio Power. A dedicated power input to Audio Boost 2 allows for a more powerful and stable power delivery, resulting in a more explosive and pure sound experience.

CREATIVE SOUND BLASTER CINEMA 2
Thanks to Creative Sound Blaster Cinema 2, you're getting amazing surround sound with just stereo headphones or speakers.
Creative Sound Blaster Cinema 2 enables you to clearly hear specific sounds in gaming environments. Hear your enemies perfectly, make your ears a decisive tool to finish on top.

DUAL HEADHPONE AMPLIFIERS
Prepare for an eargasm. The built-in dual headphone amplifier rewards your high quality headphone with the most amazing studio level sound quality up to 600Ω delivered from your gaming PC.

Tired of having to connect your headset in difficult to reach places? MSI GAMING motherboards are designed to be easy to use, featuring front & rear audio outputs fueled by Audio Boost 2.
 
HIGH QUALITY AUDIO CAPACITORS
With the use of professional Nichicon Japanese capacitors, specially designed for audio purposes, MSI GAMING motherboards provide the highest possible audio signal filtering. Delivering high fidelity crystal clear sound with exceptional acoustics and realism.

USB AUDIO POWER
When connecting multiple USB devices, most motherboards will be unable to deliver a strong 5V power signal to all USB ports. This is highly noticeable with high-quality external USB DACs where sound quality degrades as the motherboard is unable to deliver a perfect USB signal.
Only MSI USB Audio Power continuously delivers a stable 5V to the USB ports on motherboards, making sure you can continue to enjoy the crystal clear audio standard you expect.

KILLER™ E2200 GAME NETWORKING
The Killer™ E2200 Intelligent Networking Platform is built for maximum networking performance for online games and high-quality streaming media. Featuring Advanced Stream Detect™, Killer E2200 automatically detects and accelerates game traffic ahead of other network traffic for smoother, stutter-free in-game performance and the competitive edge. With this exclusive, automatic traffic prioritization, games and real-time chat get priority over low-level system chatter, giving you the lowest latency for game data on the most controllable network hardware available.

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.

FOCUS ON QUALITY
We put extra effort in increasing customer satisfaction. Our RMA rate has drastically decreased in the last few years.
To achieve the highest quality the MSI GAMING motherboards are developed by our most senior engineers on the most advanced production lines.

We are continuously improving our customer services, so in case you might run into a problem you can be assured we offer a fast response to your questions and hand you in depth information on the subject.

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.
