Server memory module

This 4 GB DDR3 module is built for servers and workstations that require error-correcting unbuffered memory. It operates at 1333 MHz with a CAS latency of CL9 and a standard voltage of 1.50 V. The stick uses a 240-pin DIMM form factor and a 2Rx8 rank configuration.

ECC UDIMM requirement

The single specification that decides fit is the ECC unbuffered design. Systems that demand registered or non-ECC memory will not accept this module. Buyers who need registered DIMMs or standard non-ECC memory must choose a different part.

240-pin DDR3 slot compatibility

It installs directly into any 240-pin DDR3 slot wired for unbuffered ECC operation. No extra power cables or cooling brackets are required. The module frees a second slot for future expansion because it delivers the full 4 GB in a single stick.

Questions about this item

What does the DDR3 1333 MHz (PC3-10600) speed mean once the module is installed in a server?

The module operates at 1333 MHz with CL9 latency and 1.50 V, providing the rated DDR3 1333 transfer rate for supported server and workstation platforms.

What interface standard does this ECC UDIMM use and what does it cap in practice?

It uses a standard 240-pin DDR3 DIMM interface, which limits the module to DDR3 signalling speeds and unbuffered ECC operation.

What physical slot and form factor does this 4 GB module require to fit and mount?

It requires a 240-pin DDR3 DIMM slot and fits the standard UDIMM height for server and workstation motherboards.
