Cooling

This motherboard is equipped with two 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.

Storage

There are four SATA III ports on this motherboard designed for traditional 2.5" and 3.5" drives. Moreover, it's also equipped with a single M.2 slot, which can utilize the PCIe 3.0 x4 interface for speeds up of up 32 Gb/s when used with a compatible NVMe drive. For an additional boost in performance, you can enable X-Boost within MSI's software.

Memory

The DDR4 memory slots on this motherboard are built with an optimized memory layout to offer stability, performance, and low power consumption. Additionally, this motherboard supports XMP for enhanced RAM speeds.

Audio

MSI Audio Boost consists of both hardware and software additions that are designed to provide you with a high-quality listening experience. The left and right channels are built on separate PCB layers, De-Pop Protection prevents loud popping noises, an EMI-shielded audio processor ensure clean stereo and surround sound, and a dedicated headphone amplifier automatically detects the optimal impedance for your headphones. For gaming, Nahimic 3 provides you with virtual surround sound with an in-game overlay that displays where noises are coming from.
