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
A larger signal eye results in improved stability, more overclocking headroom, and lower operating voltages
- Improved memory stability and compatibility
- Allows lower memory latencies at equivalent voltages
- Improved memory frequency margin
Tested by using Synopsys HSPICE simulation software
With the Energy Processing Unit (EPU) you'll enjoy system-wide power savings. The EPU automatically optimizes power consumption and maximizes savings with Away mode — a smart setting that creates an extreme energy-saving scenario by shutting down unused I/O controllers.
With Prime 300 Series motherboards you have comprehensive control over fans, water pumps, and even all-in-one (AIO) coolers ― all via Fan Expert 4 Core. Whether you're cooling with air or water, Auto-Tuning mode intelligently configures all parameters with a single click.
Cooler by design
Prime 300 Series features the most comprehensive cooling controls ever, configurable via ASUS Fan Xpert software or the UEFI BIOS.
Each header can be set to monitor and react to up to three thermal sensors. Via Fan Xpert, you can also assign a sensor to monitor the temperature of supported ASUS graphics cards to ensure optimal cooling during GPU- or CPU-intensive workloads.
Dedicated PWM/DC header for self-contained water-cooling setup, built right in.
Each onboard header supports auto-detection of PWM or DC fans.
A dedicated integrated circuit protects each fan header from over-temperature and over-current.
