Server ECC RDIMM upgrade

This 16GB DDR3 registered DIMM is built for workstations, servers and NAS systems that require error-correcting memory. It operates at 1600MHz with CL11 latency and 1.5V voltage. The module uses a 2Rx4 rank configuration and fits 240-pin DDR3 slots. It will not work in standard desktop computers that accept only unbuffered memory.

JEDEC and RoHS compliant

The memory meets JEDEC standards and is RoHS compliant, providing a warranty-safe upgrade path for OEM systems. It matches the exact specifications of Lenovo part numbers 00FE676, 03T7754, 03T8399, 03X4378 and 0A65734. No additional accessories or software are included in the package.

Registered ECC requirement

The single specification that decides compatibility is the registered ECC design. Buyers whose motherboards accept only unbuffered non-ECC DDR3 cannot use this module. Systems that require registered ECC DDR3 at 1600MHz with 2Rx4 organisation will recognise the full 16GB capacity.

Questions about this item

Will the 240-pin DDR3 RDIMM need any firmware updates or battery replacements over its service life?

No firmware or battery maintenance is required; the module is a passive JEDEC-standard DDR3 component that operates at 1.5V with CL11 timing.

What electrical or thermal limit appears first when the 16GB registered ECC module runs at 1600 MT/s continuously?

The 1.5V supply rail and CL11 latency define the electrical envelope; sustained loads stay within JEDEC DDR3 specifications without exceeding rated voltage.

How much heat and power does the 2Rx4 16GB stick produce during all-day server operation?

As a standard-voltage DDR3 RDIMM without a heat spreader, it draws nominal 1.5V power and relies on chassis airflow for cooling.
