Memory spec terms
If you're not sure if a module is right for your system, use Memory America configurator 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.

Modules exhibiting physical damage
Modules that are missing the manufacturer label containing model number, part number or serial number
Modules that are missing the manufacturer warranty label

Fully Buffered DIMM

Fully Buffered DIMM (or FB-DIMM) is a memory technology which can be used to increase reliability, speed and density of memory systems. Conventionally, data lines from the memory controller have to be connected to data lines in every DRAM module. As memory width, as well as access speed, increases, the signal degrades at the interface of the bus and the device. This limits the speed and/or the memory density. FB-DIMMs take a different approach to solve this problem. As with nearly all RAM specifications, the FB-DIMM specification was published by JEDEC.
