Memory Spec Terms

NON-ECC/Non-parity
Most desktop and laptop computers take NON-ECC or Non-parity memory.

Unbuffered
Most PCs and workstations use unbuffered memory which is faster than registered memory.

CL
CAS (column address strobe) latency, which is the number of clock cycles it takes before data starts to flow after a command is received. Lower CL is faster. Modules with different CL can be mixed on a system, but the system will only run at the highest (slowest) CL.

Voltage
For example 1.35V. Indicates the power used by the module. The lower the better.
