是指内存时序。CASLatency（简称CL值）内存CAS延迟时间，是内存的重要参数之一，某些牌子的内存会把CL值印在内存条的标签上。RAS－to－CASDelay（tRCD），内存行地址传输到列地址的延迟时间。Row－prechargeDelay（tRP），内存行地址选通脉冲预充电时间。Row－activeDelay（tRAS），内存行地址选通延迟，内...
2. tRCD: 9~11 3. tRP: 6~11 4. tRAS: 24~30 5. Command Rate: 1 / 2 6. tRC: 15~40 7. tRFC: 90ns / 110ns / 160ns / 300ns / 350ns 8. tREF: 3.9ms / 7.8msFor test of a ram timing component, other components (except tRC and tREF) are set to the lowest possi...
涉及到的参数分别为: CPC : Command Per Clock tCL : CAS Latency Control tRCD : RAS to CAS Delay tRAS : Min RAS Active Timing tRP : Row Precharge Timing tRC : Row Cycle Time tRFC : Row Refresh Cycle Time tRRD : Row to Row Delay(RAS to RAS delay) tWR : Write Recovery Time ……及...
CL=5-5-5-15是指内存时序，依次按分别为：CAS#延迟(CL) - RAS#至CAS#延时(tRCD) - RAS#预充电(tRP) - 周期(tRAS) - 存储周期(tRC)内存时序一定程度上代表了内存条的性能，各项参数越低越好。但是一般的内存，运行在特定频率下的时候，其时序是固定一致的。有部分高端超频内存条，时序往往...
