Crucial Ballistix Elite 32GB Kit (4 x 8GB) DDR3-2133 UDIMM Desktop Memory 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 & laptop computers take NON-ECC or Non-parity memory. ECC/ Parity ECC or parity modules look for errors in data & are most often found in servers & other mission-critical applications used by large networks & businesses. Unbuffered Most PCs & 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: 64 Meg 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. Check the glossary & knowledgebase for more detailed definitions.
