如果你的BIOS没有CPU PCIE ASPM设置，但是有这样的设置 那么逐一调整每根插槽的ASPM模式就行了 第五步...
在BIOS中已经开放CPU PCIE ASPM Control选项的主板,当设置为L1模式的时候是一定会生效的,但是通过Setup命令去调整的话就不一定。 将CPU PCIE ASPM Control调整为L1 Entry模式并且确认生效后,事实上X570芯片已经处于能效最高模式,只要外围设备支持——比如独立声卡、网卡等,均能工作在L1模式 第六步:制作UEFI启动U盘,...
这种电源是PCI-E的ASPM模式。PCI-E ASPM（Active State Power Management）是一种电源管理技术，用于在PCI-E设备之间实现高效的电源管理。通过在设备闲置时关闭设备来减少电能消耗，保持设备的可用性，以便在需要时快速恢复工作。
