what measures memory access timing? Mon May 21 2018 · Access time. Access time is total time it takes a computer to request data and then that request to be met. A good analogy is the time between you ordering a pizza and it being delivered. Access time pertains to devices such as memory hard drive CD-ROM or other mechanisms . When overclocking your memory you may need to increase the memory timings in order to make the system run in a stable manner . Here is where something very interesting happens. Due to the increased timings the memory may achieve a lower performance even though it is now configured to run at a higher clock rate ... Memory timings or RAM timings describe the performance of synchronous dynamic random-access memory (SDRAM) using four parameters: CL TRCD TRP and TRAS in units of clock cycles; they are commonly written as four numbers separated with dashes e.g. 7-8-8-24. The fourth (tRAS) is often omitted or a fifth the Command rate sometimes added (normally 2T or 1T also written 2N 1N). These parameters specify the latencies (time delays) that affect speed of random access memory. Lower num… Memory RAM Speed - Access Time Megahertz (MHz) Bytes Per Second. Prior to SDRAM speed was expressed in terms of nanoseconds (ns). This measured the amount of time it takes the modu...
