  • IEEE 802.11n


The OC PCB used for the MSI overclocking motherboards has an excellent design in which 50% more layers are used compared to standard motherboards. This allows 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.

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.

Direct USB allows for faster and more convenient ways of saving scores, flashing the BIOS and installing drivers & 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.
