这些丰富的功能也有助于主板提供稳定且强大的性能。
MORE FOR PERFORMANCE
- HIGH-EFFICIENCY MODE
- Latency Killer
The High-Efficiency Mode is designed to optimize memory performance byincreasing memory bandwidth and reducing latency. With the four sets of RAM timing settings, it allows users to find out the optimal configuration based on the quality of their memory modules.
MSI BIOS has introduced the latest Latency Killer feature on all AM5 socket motherboards. Users can enable Latency Killer in the BIOS to reduce memory latency by up to 12% when running at high frequencies. Importantly, it is compatible with a wide range of memory overclocking features, including Memory Try It!!, EXPO, A-XMP, and High-Efficiency Mode, etc.
UP TO 12% Memory latency Reduction
*Supports BIOS versions after AGESA 1.2.0.2b.
- TVS
- 实心针脚设计
- 过电流保护
- 电源相位接地架构
瞬态电压抑制器(TVS) 是用来防止电压过高的安全装置。微星所有主板均配置TVS。 当电压异常升高时,TVS从高电阻状态切换到低电阻状态,将过高的电压转移到地上,有助于防止高电压造成的电路损坏。
MSI 主板4-pin、8-pin 和24-pin 电源接头均采用实心针脚设计。实心针脚设计优点在于处理高电流负载时,能更安全且稳定地将12V 电力传输至处理器。
实心针脚电源端口的优势
- 提升稳定性:较大的接触面积,强化电力传输的稳定性。
- 低阻抗:实心针脚拥有低阻抗优势,实现高效能电流传输。
- 强韧耐用:实心针脚设计具有出色的耐用性,能够应对严苛的使用环境。
- 适用于高电流场景
MSI 主板内建过电流保护 (OCP) 优先考虑安全性, 确保 USB 端口、DDR 内存、PWM IC 和 CPU 等关键组件免受过电流影响。 这种主动防御机制可降低因过多电流突然涌入而造成损坏或故障的风险, 从而促进系统的长期稳定性。让 MSI 玩家使用的更安心。
电源相位的接地架构是微星独家设计。这项专利设计能够抑制电源相位所产生的电磁干扰(EMI), 并有助于有效地将热能传导到具有接地特性的铜平面。
