We've melded all the good stuff that's packed into the latest processors with essential ASUS design and engineering, so you benefit from industry-leading technologies — including automated system tuning, comprehensive cooling controls, and immersive onboard audio. When you build with an ASUS Prime 300 Series motherboard, you build smart, easy and affordably.

Improved DDR4 stability

ASUS OptiMem preserves memory signal integrity by routing traces and vias to the optimal PCB layer, and our T-Topology trace layout ensures time-aligned signaling by balancing trace lengths between memory slots. These enhancements allow the Prime 300 Series to support a wide range of dual and quad-DIMM memory kits, while providing your rig with the stability it needs to deal with any type of workload - whether you're gaming or running intensive applications.

ASUS OptiMem benefits

• Improved memory stability and compatibility
• Allows lower memory latencies at equivalent voltages
• Improved memory frequency margin

USB 3.1 Gen 1 front-panel connector

• Future-proof connectivity
• USB 3.1 Gen 1 is right where you need it, with two super-speed headers for the front panel. Experience data-transfer speeds up to 10X faster than USB 2.0 with instant plug-and-play connectivity, and avoid back-breaking contortions in the hunt for hard-to-reach rear ports.

Speed up with onboard M.2

With x4 PCI Express® 3.0/2.0 bandwidth, M.2 supports up to 32Gbps data-transfer speeds. It's the perfect choice for an operating system or application drive, providing fast access to data.

Intel Optane memory ready

Intel Optane™ is a revolutionary non-volatile memory technology supported by Prime 300 Series motherboards. Intel Optane memory modules accelerate attached storage to reduce boot and load times, so everything feels faster and more responsive.
