Hello Cody, Thank you for your post, In most cases you shouldn't worry about your memory timings. As long as you purchase memory that the Crucial® Advisor™ tool or System Scanner tool says is compatible with your computer, you can be assured that you have memory that is capable of running in your system. The only exception to this rule is when purchasing high performance parts for custom built systems. Some CPUs are limited with the memory speed and latencies they will support, so it’s always a good idea to check the max memory speed your CPU will support, before paring it with any higher-end memory. Most would think that the lower the CAS Latency the better, as this value refers to your memory's ability to quickly respond to new information. This isn't completely accurate as newer memory types typically have much higher CAS latency times than their older counterparts. Why do new memory types have slower latency times? Along with different timings, there is an attribute called Clock Cycle Time. This is a measurement reflective of how quickly the memory can be ready for a new set of commands. New memory types, like DDR4, have significantly faster Clock Cycle Times than older memory. This effectively means the True Latency (real speed) is much faster.
