Step 1: Get the installer for CPU-Z and install it once the download completes. You can go through the following steps to know the CAS Latency of your RAM: It is a very popular tool that provides all kinds of useful information about your computer’s hardware including the CAS Latency speed of the RAM. Method 1: via CPU-Zīy far the easiest method is to install a freeware called CPU-Z. You can try any of the 4 methods listed below to find the CAS Latency of your RAM without any hassles or potential mistakes.

Each number in the series signifies some timing value and things might start to get confusing at this point. Instead, it might be mentioned within a series of numbers that are printed on your RAM. So, how will you determine your RAM stick’s CAS Latency? It may not be written directly on your RAM. In short, it is a measure of how quickly the RAM serves up the requested data. There are several other factors like CAS latency, for instance, that affects a RAM’s performance.ĬAS Latency is the time delay between a data request and data delivery by the RAM. However, the clock frequency is only the theoretical limit of a RAM’s performance. So, if we have two different RAM sticks that have clock frequencies of 2133Mhz and 2400Mhz respectively, then we think of the 2400MHz RAM to be faster. We often judge a RAM’s performance based on the clock frequency. Is a Higher or Lower CAS Latency Better?.Method 4: via Physically Examine RAM Modules.
