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.
