Ram Latency Calculator


About Ram Latency Calculator (Formula)

RAM Latency is a measure of the time it takes for a computer to access data stored in its Random Access Memory (RAM). The lower the latency, the faster the computer can access the data. Latency is measured in nanoseconds (ns) and it is often used as one of the factors to evaluate the performance of the computer’s memory.

The formula for calculating Ram Latency is:

RAM Latency = (CAS Latency x tCLK) / 1000


  • CAS Latency (CL) is the number of clock cycles that pass between the moment a command is issued and the moment data is available
  • tCLK is the clock speed of the memory in nanoseconds

Ram Latency calculators are commonly used in computer hardware and technology to calculate the latency of the computer’s RAM. They can be found in spreadsheet software or as online calculators, and can be used to calculate the RAM Latency for a given computer based on its CAS Latency and Clock speed. Low latency memory is considered to be desirable for high performance systems, such as gaming and workstation computers.
