32GB DDR5 4800MHz ECC RDIMM for IBM-Lenovo servers

This 32GB registered DIMM uses DDR5 technology at 4800MHz with ECC error correction. It targets administrators upgrading IBM-Lenovo systems that require part numbers 4X77A77031, 4X77A83156, 4X77A89485, SM37B06935 or 03KH607. The module operates at the standard 1.10V DDR5 voltage.

DDR5 288-pin registered interface limits

The 288-pin RDIMM form factor fits only DDR5 server platforms that support registered memory with on-die ECC. Consumer desktop boards and laptops using unbuffered DDR5 cannot accept this module. Maximum throughput is defined by the PC5-38400 data rate and CL40 latency specified for this part.

2Rx8 dual-rank organisation decides fit

The 2Rx8 rank structure determines how the memory controller addresses the module and affects maximum population rules for each channel. Systems requiring single-rank 1Rx8 or quad-rank 4Rx4 modules will not match this organisation. Verify the server documentation for supported rank configurations before purchase.

Questions sur cet article

Should I pick this 32GB 4800MHz module or a different capacity?

This module is a single 32GB stick rated DDR5-4800 CL40. Add identical sticks to fill your server's channels for maximum bandwidth.

What does the DDR5-4800 rating deliver in my server?

It runs at 4800MT/s with CL40 timing at 1.10V, providing standard DDR5 bandwidth and ECC error correction for stable server workloads.

How does the RDIMM interface affect what I can install?

The 288-pin RDIMM format with 2Rx8 organisation requires a server motherboard that supports registered ECC DDR5; it will not fit desktop boards.
