三、内存性能测试：开启D5 Single Boost带宽提升25% 延迟降低11ns

测试使用的是芝奇幻锋戟Z5 RGB DDR5-7200 24GBx2套条，时序36-46-46-115。分别测试双通道、单通道，以及单通道下开启D5黑科技Plus下的内存性能。

首先是双通道下开启XMP，实测内存读取、写入与复制带宽分别是100GB/s、87GB/s、89GB/s，延迟88.1ns。

拔掉一根内存，变成24GB单通道模式，内存读取、写入与复制带宽为53GB/s、45GB/s、47GB/s，延迟89.5ns。

同样24GB单通道模式，在BIOS打开D5 Single Boost Technology，频率从7200MHz提升到了8000MHz，且时序变为40-50-50-54，特别是rRAS，此时的内存读取、写入与复制带宽分别为67GB/s、61GB/s、67GB/s、内存延迟78.1ns。

也就是带宽提升25%，延迟降低了11ns。
