Server-grade DDR3L ECC RDIMM kit

This OWC kit supplies two 8 GB registered DDR3L modules running at 1600 MHz with CL11 latency at 1.35 V. It is built for Lenovo System x3650 M4, x3650 M4 BD, x3650 M4 HD, x3750 M4 and x3755 M3 servers that require ECC registered memory.

Replaces Lenovo 00D5035 00D5036 46W0700 46W0771

The modules directly substitute the listed Lenovo part numbers when expanding or refreshing memory in the compatible systems. The upgrade is worthwhile when the server currently runs unbuffered DIMMs or has empty registered slots and the workload demands error-correcting registered memory.

Steady throughput under continuous load

Registered buffering and ECC correction maintain data integrity during sustained multi-threaded workloads typical of virtualisation or database tasks. The 1.35 V operation reduces power draw compared with standard 1.5 V DDR3 while the JEDEC-compliant 1600 MHz rating keeps timing consistent over long periods.

Questions about this item

Will the 240-pin DDR3L RDIMMs fit the memory slots in my Lenovo System x3650 M4?

Yes, the 240-pin DDR3L 1600 registered DIMMs are designed for the x3650 M4, x3650 M4 BD, x3650 M4 HD, x3750 M4 and x3755 M3.

Do I need to install both 8 GB modules together, or can I add just one?

Install the two 8 GB modules as a matched pair in the correct channel slots; mixing registered and unbuffered memory is not supported.

How long before the ECC registered modules typically need replacement in a server?

The modules are built to JEDEC and RoHS standards with a limited lifetime warranty, so they generally last the useful life of the x3650 M4 platform.
