Summary |
Dependable and Versatile Workstations Motherboard.
Designed to deliver powerful performance, manageability and reliability for high speed computing workstations.
SPS (Smart Power Stage)
Dr.MOS design features the latest SPS (Smart Power Stage) technology. It’s optimized for monitoring current and temperature of each phase, thus delivering smoother and neater power to the CPU with enhanced performance and OC capability.
20+2 Power Phase Design
Featuring sturdy components and completely smooth power delivery to the CPU. Plus, it offers unmatched overclocking capabilities and enhanced performance with the lowest temperature for advanced gamers as well.
14 Layer PCB
The 14 Layer PCB provides stable signal traces and power shapes delivering lower temperature and higher energy efficiency for memory overclocking! Thus, it's able to support the latest memory modules with most extreme memory performance!
Optimized VRM Design
The advanced cooling system of the composite VRM heatsink provides efficient heat dissipation, which means users can enjoy high-performance computing without having to worry about thermal issues. The triple EBR cooling fans, XXL aluminum-alloy heatsink, aluminum fin array, and heat pipe work together to maintain optimal temperature levels for the system, ensuring smooth and stable operation even under heavy workloads.
Server-Grade Ultral Low-Loss PCB
The server grade PCB prevents PCB bending and improves signal integrity, giving higher PCIe 5.0 and memory performance as well as system stability, giving a reliable and long-lasting system without any compromise.
Digi Power
Unlike traditional motherboards that use analog power, this motherboard uses a next generation digital PWM (Pulse-Width Modulation) design, which provides CPU Vcore voltage more efficiently and smoothly, so that the stability and lifespan of the motherboard is greatly enhanced.
DDR5 ECC Memory Support
This workstation motherboard supports 8 DIMMs Quad-Channel DDR5 RDIMM ECC Memory overclocking with max capacity of 2048GB and is able to automatically detected and corrected data corruption, reducing the chance of system crashes to ensure workstation stability with multiple memory modules.
PCIe 5.0 + Surface-Mount Tech
Compares to conventional DIP style PCIe slot, the SMT type PCIe slot improves signal flow and maximize stability under high speed, a key breakthrough to fully support the lighting speed of the latest PCIe 5.0 standard.
The latest PCI Express 5.0 is capable to perform a breathtaking bandwidth of 128GBps, ready to unleash the full potential of future high end graphic cards.
4 x PCIe Gen5 x16
This workstation motherboard supports 4 PCIe Gen5 x16 slots, deliver all the performance of PCIe Gen5 to your GPU and add-on cards. Fulfill all the professional design, deep learning, simulation and rendering applications.
