Server ECC RDIMM Upgrade

This 8GB DDR3L registered DIMM is built for Lenovo System x3650 M4, x3650 M4 BD, x3650 M4 HD, x3750 M4 and x3755 M3 servers. It provides ECC error correction and registered buffering for stable operation in multi-module configurations. The module is not compatible with standard desktop computers and cannot be mixed with unbuffered memory.

Registered ECC Requirement

The single specification that decides fit is the registered ECC design. Only systems that accept 240-pin DDR3L ECC registered RDIMMs can use this module; it will not work in slots wired for unbuffered or non-ECC memory. Verify the server documentation lists registered ECC support before ordering.

Low-Voltage Thermal Profile

Operating at 1.35V, the DDR3L module draws less power and generates less heat than standard 1.5V DDR3. No heat spreader is fitted, so airflow across the DIMM slots handles cooling silently in normal server use.

Questions about this item

What does the 1600 MHz speed mean once the module is installed in a compatible Lenovo server?

The module runs at 1600 MHz DDR3L, delivering PC3L-12800 bandwidth when the platform memory controller operates at that frequency.

How does the DDR3L ECC Registered interface affect what the module can do in practice?

The registered design adds a clock cycle of buffering for signal integrity, and ECC corrects single-bit errors; it only works in systems that support registered ECC DDR3L.

What physical slot and keying does the 240-pin DIMM need to fit the listed Lenovo models?

It requires a standard 240-pin DDR3 DIMM socket with DDR3L keying; the module is unbuffered height with no heat spreader.
