Server ECC RDIMM Upgrade Kit

This OWC kit supplies 32GB of DDR3L ECC registered memory in a matched pair of 16GB modules. It is built for Lenovo ThinkServer RD330, RD340, RD430, RD440 and RD530 systems that require registered DIMMs. The modules will not work in standard desktop boards or alongside unbuffered memory.

JEDEC Compliant Low Voltage Modules

Each 240-pin DIMM runs at 1.35V to meet PC3L-12800 1600MHz CL11 specifications. The registered buffer and ECC logic reduce electrical load on the memory controller and correct single-bit errors, helping maintain data integrity in continuous server workloads.

32GB Capacity for Multi-Socket Servers

The 2x16GB configuration populates two slots with 2Rx4 organisation, leaving remaining slots free for further expansion up to the platform limit. It suits virtualisation hosts and database nodes that benefit from ECC protection, but it cannot be used in systems that only accept unbuffered non-ECC DDR3L.

Questions sur cet article

Will the 2Rx4 registered DIMMs need any firmware updates or battery-backed spares over time?

No firmware or battery-backed components are required; the modules are solid-state DDR3L 1600 CL11 1.35V ECC registered DIMMs with no moving parts.

What thermal or power ceiling appears first when the kit runs at 1600 MHz continuously in a ThinkServer RD430?

Each 16 GB module draws 1.35 V at DDR3L 1600 speeds; the registered buffer and ECC logic add minimal overhead, so the platform's DIMM-slot power budget is reached before the memory itself throttles.

How much heat and fan noise should I expect from the two 240-pin sticks in a RD530 running 24/7?

The modules have no heat spreader and operate at 1.35 V, so they add little heat; system fan curves dominate any audible noise increase.
