Server memory for enterprise workloads

This 16GB DDR3 module runs at 1866 MT/s with CL13 timing and 1.50V operation. It is built for servers and workstations that require registered ECC memory to maintain data integrity under sustained load.

Suited for registered ECC platforms only

The module uses a 240-pin DDR3 interface with registered signalling and 2Rx4 organisation. Systems that accept only unbuffered non-ECC memory cannot use this part, and boards limited to lower DDR3 speeds will not reach the rated 1866 MT/s.

Registered ECC with 2Rx4 organisation

The single specification that decides fit is the registered ECC design combined with 2Rx4 rank configuration. Your motherboard must explicitly support registered ECC DDR3 and the 2Rx4 layout for this module to function.

Perguntas sobre este artigo

Does the 240-pin DDR3 module fit a standard server DIMM slot?

Yes, the 240-pin DDR3 form factor matches standard registered DIMM slots used in compatible servers.

What is the correct seating procedure for the registered ECC module?

Align the notch with the slot key, press down firmly until both retention clips click, confirming the 16 GB 2Rx4 module is fully seated.

When should the 1.5 V DDR3 1866 memory be replaced?

Replace the module if system logs report uncorrectable ECC errors or if memory diagnostics fail during scheduled maintenance.
