Server ECC RDIMM upgrade

This 16GB DDR3L registered DIMM is built for Lenovo ThinkServer RD540, RD630, RD640, TD330 and TD340 systems. It delivers ECC protection and registered signalling required by server chipsets. The module will not work in standard desktop boards or alongside unbuffered memory.

Registered DDR3L 1600 CL11

The single decisive specification is the registered ECC design at DDR3L 1600 CL11 1.35V. Only systems that accept 240-pin DDR3L RDIMMs with 2Rx4 organisation can use this module. Desktop DDR3L UDIMMs or non-ECC variants are electrically incompatible.

Sustained server workloads

ECC corrects single-bit errors continuously during long compute runs, preventing silent data corruption. Registered buffering reduces electrical load on the memory controller, keeping signal integrity stable across fully populated channels over extended uptime.

Questions about this item

How does the 1600 MHz speed translate once the module is installed in a ThinkServer?

The module runs at DDR3L 1600 (PC3L-12800) with CL11 latency, delivering the rated throughput when the server's memory controller operates at that frequency.

What does the 240-pin DDR3L ECC Registered interface mean for compatibility and bandwidth limits?

It fits 240-pin DDR3L RDIMM slots on the listed ThinkServer models; the registered buffer and ECC are required by those platforms and the PC3L-12800 rating caps the maximum transfer rate.

Will this 2Rx4 240-pin DIMM physically seat in a Lenovo ThinkServer RD540, RD630, RD640, TD330 or TD340?

Yes — the 240-pin DDR3L RDIMM form factor matches the memory slots on all five ThinkServer models and the 2Rx4 organisation is supported by their memory controllers.
