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.

200-pin SODIMM

A small outline dual inline memory module (SODIMM) consists of a number of memory components (usually black) that are attached to a printed circuit board (usually green). SODIMMs get their name because they are smaller and thinner than regular DIMMs. The gold pins on the bottom of the SODIMM provide a connection between the module and a socket on a larger printed circuit board. The pins on the front and back of a SODIMM are not connected.

200-pin SODIMMs are used to provide DDR and DDR2 SDRAM memory for notebook computers. 200-pin SODIMMs are available in PC2700 DDR SDRAM, PC3200 DDR SDRAM, DDR2 PC2-6400 SDRAM, DDR2 PC2-5300 SDRAM, DDR2 PC2-4200 SDRAM and DDR2 PC2-3200 SDRAM. To use DDR or DDR2 memory, your system motherboard must have 200-pin SODIMM slots and a DDR- or DDR2-enabled chipset. A DDR or DDR2 SODIMM will not fit into a standard SDRAM SODIMM socket. (Information about which memory technology your system uses is included in the Crucial Memory Advisor™ tool.)

The number of black components on a 200-pin SODIMM can vary, but it always has 100 pins on the front and 100 pins on the back, for a total of 200. 200-pin SODIMMs are approximately 2.625 inches long and 1.25 inches high, though the heights can vary. Like 144-pin SODIMMs, 200-pin SODIMMs have one small notch within the row of pins; however, the notch on the 200-pin SODIMMs is closer to the left side of the module.
