What’s the difference between CL2 and CL3?
CL; CAS (Column Access Strobe) is the initials of the Latency words, which indicates the time the module takes to reach the database. CL2 and CL3 base the clock cycles before the data is sent. CL2 modules cycle for two hours before data is sent. The CL3 modules cycle for three hours before data is sent. CL2 modules are faster because they only wait for two hours, so they are more expensive. Some systems use only one of CL2 and CL3.
