16GB DDR5 ECC RDIMM for Lenovo Servers

This 16GB DDR5 4800MHz registered DIMM delivers error-correcting memory for compatible IBM-Lenovo servers. The module uses major-brand chips and operates at the standard 1.1V DDR5 voltage. It targets administrators upgrading ThinkSystem platforms that require registered ECC memory.

Fits 288-pin DDR5 slots in qualified ThinkSystem

The single-rank 1Rx8 module installs directly into available DDR5 DIMM sockets without adapter hardware. Registered buffering reduces electrical load on the memory controller, freeing capacity for additional modules in multi-socket configurations. Verify your server's qualified vendor list before installation.

Tested module replaces Lenovo part numbers

Each unit undergoes quality assurance testing to confirm reliable operation at CL40 latency. The package contains one 16GB DIMM ready for deployment. Lifetime warranty and US-based technical support accompany the hardware.

Questions sur cet article

How does the registered design and 1.10 V voltage affect all-day thermal load?

Registered buffering and the standard 1.10 V DDR5 voltage keep power draw modest, helping the module run cooler under continuous server workloads.

What motherboard slot and memory standard must the system already support for this 288-pin module to function?

The system needs a DDR5 RDIMM slot accepting 288-pin registered ECC modules at 4800 MHz.

What is the first bottleneck that appears during sustained heavy use of this CL40 4800 MHz module?

The CL40 latency at 4800 MHz becomes the limiting factor for sustained throughput before capacity or voltage constraints.
