Unverified评估DDR5真实延迟看'时序CL÷频率×2000'得出的纳秒值，DDR5-6000 CL30约等于10ns，与DDR5-6400 CL32相近；单看CL数字大小无意义85% similarUnverifiedDDR4平台首选DDR4-3200 CL16或DDR4-3600 CL18，这是Intel/AMD双方性价比甜点；超过3600MHz对DDR4提升边际递减且需要挑主板体质78% similarUnverifiedDDR5插满四根内存（4×16G）会显著降低可稳定运行的频率，主板通常只能跑到4000-4800MHz；追求高频高容量应选两根32G而非四根16G77% similarUnverifiedDDR6预计最高带宽约为256GB/s（单通道），DDR5总线位宽仅为64位74% similarUnverified带RGB灯条和高马甲散热的内存通常有溢价，DDR4在3600MHz以下、DDR5在6000MHz以下的正常使用无需担心散热，马甲主要为超频和美观服务73% similar
