WebFeb 7, 2024 · CAS latency is the number of clock cycles delayed between the moment RAM data is requested by your CPU and the time this data is available. When the memory controller calls for access to a location, the data needs to go through clock cycles in the CAS to get to the final address and finish the command. WebIn general, clock latency (or clock insertion delay) is defined as the amount of time taken by the clock signal in traveling from its source to the sinks. Clock latency comprises of two components - clock source latency and clock network latency.
