An 8 GB DDR3L ECC registered DIMM running at 1600 MHz with CL11 latency for compatible Lenovo ThinkServer models
Capacity 8GB
This OWC module provides 8GB of DDR3L ECC registered memory running at 1600MHz with CL11 latency. It uses a 240-pin RDIMM form factor and operates at 1.35V. The single-rank 1Rx4 design is built for Lenovo ThinkServer RD540, RD630, RD640, TD330 and TD340 systems.
The module replaces Lenovo part numbers 00D5035, 00D5036, 46W0700 and 46W0771. Upgrading is worthwhile when your current server memory is insufficient for virtualisation workloads or when replacing failed registered DIMMs. It will not work in standard desktop computers or alongside unbuffered memory.
Confirm your ThinkServer model matches the supported list before ordering. Ensure all populated slots use registered ECC DDR3L modules at 1.35V to avoid mixing memory types. Check the system documentation for maximum capacity per channel and population rules for 1Rx4 modules.

Yes, the module is a 240-pin DDR3L ECC Registered DIMM built for the ThinkServer RD540, RD630, RD640, TD330 and TD340 platforms.
Power down, open the chassis, align the notch on the 240-pin edge connector with the slot key, press firmly until both retention clips click, then verify in BIOS that the registered ECC DIMM appears at 1600 MHz.
Replace the module if memory diagnostics report correctable ECC errors that increase over time, if the system fails to POST with the DIMM installed, or when a planned capacity upgrade requires higher-density registered modules.
