ASUS Prime 300 Series motherboards provide the solid
foundation needed for your first build, plus flexibility to grow with your
ambitions. We've melded all the good stuff that's packed into the latest 8th
Generation Intel® Core™ 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
Tested by using Synopsys HSPICE simulation software
Cooler by design
Prime 300 Series features the most comprehensive cooling
controls ever, configurable via ASUS Fan Xpert software or the UEFI BIOS.
Media-acclaimed UEFI BIOS
The UEFI BIOS is an early waypoint on any PC-building
journey, and Prime 300 Series has one of the best in the business.
USB 3.1 Gen 1 front-panel connector
Future-proof connectivity
USB 3.1 Gen 1 is right where you need it, with four
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.
