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.
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.
Much like the design of the I/O Cover, this awesome looking piece of protective shield helps to keep the audio signal pure, preventing interference from other components. This is extremely important when demanding high quality sound.
Protective I/O Cover
A black design I/O Cover with GAMING 9 imprinted doesn't only look cool, but it also protects against Electro Magnetic Interference. Making sure whatever device you connect, you will always receive a pure signal.

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
