CAS Latency

What is Cas Latency?

CAS Latency is a measure of the delay between the time when a memory controller sends a request for data to a Random Access Memory (RAM) module and the time when the data is actually available for use.

It is often used as a benchmark for the performance of RAM modules. CAS Latency is measured in clock cycles, with lower values indicating faster performance. For example, a RAM module with a CAS Latency of 16 will take 16 clock cycles to deliver requested data, while a module with a CAS Latency of 14 will take only 14 clock cycles. CAS Latency is just one factor that affects the overall performance of RAM modules, and other factors such as clock speed and memory size also play important roles. However, when choosing RAM modules, it is generally recommended to choose those with the lowest CAS Latency possible within your budget, as this will typically result in faster overall performance.
