Memory spec terms
If you're not sure if a module is right for your system, use the Crucial Memory Advisor tool for a list of guaranteed compatible modules.

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

ECC/Parity
ECC or parity modules look for errors in data and are most often found in servers and other mission-critical applications used by large networks and businesses.

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

Registered/Buffered
Registered or buffered modules delay all information transferred to the module by one clock cycle. This type of memory is primarily used in servers.

Fully buffered
Designed for next-generation servers, features an advanced memory buffer.

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.

Component configuration
(For example: 64Meg x 64) Indicates the size of the memory chip components on the module.

Voltage
For example 2.6V. Indicates the power used by the module. The lower the better.
