16GB DDR4 2400MHz ECC RDIMM for Lenovo ThinkServer

This OWC module is a 16GB DDR4 2400MHz ECC Registered RDIMM built for Lenovo ThinkServer systems. It runs at PC4-19200 speed with CL17 latency and 1.2V voltage. The 288-pin 2Rx8 design includes error-correcting code and registered buffering for server stability.

Suits ThinkServer RD350 RD450 RD550 RD650 TD350

It fits Lenovo ThinkServer models RD350, RD450, RD550, RD650 and TD350 using the E5-2600 v4 platform. Buyers who need unbuffered memory for a standard desktop should look elsewhere. It cannot be mixed with non-ECC or unbuffered modules in the same system.

Simple DIMM slot installation no heat spreader

Installation is a standard DIMM insertion into the 288-pin DDR4 slots on the supported ThinkServer boards. The module has no heat spreader, so ensure adequate chassis airflow. The main issue is attempting to use it in a consumer desktop or mixing it with unbuffered memory, which will prevent boot.

Perguntas sobre este artigo

Which Lenovo ThinkServer models must I already own for this OWC 16GB DDR4 2400MHz ECC RDIMM to work?

This module is validated for Lenovo ThinkServer RD350, RD450, RD550, RD650 and TD350 systems built on the E5-2600 v4 platform.

Can I keep my existing unbuffered DDR4 DIMMs and add this 2Rx8 registered ECC module alongside them?

No — registered ECC memory cannot be mixed with unbuffered DIMMs; all slots must use registered ECC modules of matching specification.

How do I confirm the 2400MHz CL17 1.2V module is running correctly after installation?

Check the system BIOS or UEFI memory information screen — it should report 2400 MT/s speed, CL17 latency, 1.2 V voltage and ECC registered status for each installed DIMM.
