What is the difference in performance between memory timings vs CAS latency (CL)?
The higher memory timings, the better. The lower the CAS latency (CL), the better. You can also get better performance by using the overclocking feature. Normal players may choose the RAM with higher memory timings while overclocking plays should take both memory timings and CL into consideration. The RAM with overclocking features is relatively expensive. Please refer to the post from Team Group for further explanation.
