It has four RAM slots that can hold up to 64GB of dual-channel DDR4 memory at speeds of up to 3466 MHz when overclocked. For storage, there are four SATA III ports and a single M.2 slot that can operate at up to 32 Gb/s when used with a compatible NVMe drive. While this motherboard is equipped with DVI-D and HDMI ports for onboard graphics, it also has a PCIe 3.0 x16 slot for a dedicated GPU as well as a PCIe 2.0 x16 and four PCIe 2.0 x1 slots for additional PCIe-based hardware. Other notable features include Realtek ALC892 7.1-channel HD audio and Realtek 8111H Gigabit LAN. Cooling This motherboard is equipped with six fan headers that support both DC and PWM modes, so you adjust their speeds either manually or automatically within BIOS or a third-party software to find a balance between cooling and noise. Audio MSI Audio Boost consists of both hardware and software additions that are designed to provide you with a high-quality listening experience.
