ECC Registered DDR3L Kit for Lenovo Servers

This 16 GB kit contains two 8 GB DDR3L 1600 CL11 registered DIMMs built for Lenovo System x3300 M4, x3500 M4, x3530 M4, x3550 M4 and x3630 M4 servers. ECC error correction and registered buffering protect data integrity in workloads that cannot tolerate silent corruption. It is not compatible with standard desktop motherboards or unbuffered memory slots.

240-Pin 1.35 V Modules in a Matched Pair

Each module uses a 240-pin DDR3L interface at 1.35 V and is organised as a single-rank 1Rx4 device. The matched pair allows the server to populate two slots in lockstep, leaving remaining DIMM sockets free for future expansion. The kit replaces Lenovo part numbers 00D5035, 00D5036, 46W0700 and 46W0771 without requiring BIOS changes beyond standard JEDEC detection.

Low-Voltage Operation Without Heat Spreaders

Running at 1.35 V reduces power draw compared with standard 1.5 V DDR3, helping the server’s cooling subsystem maintain lower inlet temperatures. The modules ship without heat spreaders, relying on chassis airflow for passive cooling; acoustic impact is negligible in typical rack environments.

Perguntas sobre este artigo

Does the DDR3L 1600 CL11 ECC RDIMM reach its 1.35 V limit before the server CPU throttles under sustained load?

The modules run at 1.35 V, the standard DDR3L voltage, so the memory controller stays within spec during continuous operation.

How much heat does the 2 x 8 GB kit produce when the Lenovo x3550 M4 runs all day?

No heat spreader is fitted; the registered ECC design keeps power draw low at 1.35 V, letting the server's existing airflow handle cooling.

Which Lenovo part numbers must the x3630 M4 already use for this 240-pin kit to work?

It replaces Lenovo 00D5035, 00D5036, 46W0700 and 46W0771, so the server must accept those FRUs.
