What it means:
Data Rate - DDR-1066 - Double Data Rate @ 533MHz *2 The Front Side Bus (FSB) connects the Central Processor Unit (CPU) to a Memory Controller HUB (MCH). THe memory bus is typically slower than the CPU. NON-ECC/Non-parity Ñ Most desktop and laptop computers take NON-ECC or Non-parity memory.
ECC/Parity Ñ 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 Ñ Most PCs and workstations use unbuffered memory which is faster than registered memory.
Registered/Buffered Ñ 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 Ñ Designed for next-generation servers, features an advanced memory buffer.
CL Ñ 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 Ñ (For example: 64Meg x 64) Indicates the size of the memory chip components on the module.
Voltage Ñ For example 2.6V. Indicates the power used by the module. The lower the better.
DDR SDRAM - Double data rate synchronous dynamic random access memory
