Cas Latency or Timing Definition

The simplest way to think of cas latency (or timings) is by associating it with how much delay your ram will have. Timings represent the gap between the processor sending information to the RAM and the RAM responding to it. High cas latencies will result in slower RAM.

You can expect that as memory becomes faster it will naturally have higher timings. For example, memory with a speed of 1066 Mhz will likely have a cas latency of 5-5-5-15. Whereas, memory with a speed of 2133 Mhz will possibly have a cas latency of 9-11-10-28. Aim to find RAM with a high speed first. Then focus on finding one with the lowest cas latency.
