32 GB DDR5-6400 RDIMM for servers

This 32 GB DDR5-6400 registered DIMM adds ECC-protected capacity to dual-socket server boards. It targets administrators expanding memory in virtualisation hosts, database nodes or HPC clusters where data integrity matters. The registered design reduces electrical load on the memory controller.

Capacity and headroom

Each module delivers 32 GB across eight 4 Gb Hynix die in a 2Rx8 layout. The density suits workloads that fit in a few hundred gigabytes; larger in-memory databases or dense VDI deployments will need more slots populated. The dual-rank organisation helps bandwidth but limits maximum ranks per channel.

Thermals noise and power

Operating at 1.10 V, the module draws modest power for DDR5-6400 speeds. Passive cooling in standard server airflow is sufficient; no active fans attach to the DIMM itself. Acoustic contribution is zero, and the low voltage keeps thermal headroom comfortable in packed chassis.

Questions about this item

Will the 288-pin DDR5 RDIMM run alongside DDR5 modules already installed in my server?

The module uses the standard 288-pin DDR5 RDIMM form factor and operates at 1.10 V, so it fits the same slots as other DDR5 registered DIMMs. Mixing different speeds or timings will force all channels to run at the lowest common speed and latency.

How can I confirm the 32 GB module is running at DDR5-6400 with CL52 after installation?

Check the BIOS memory information or a tool such as CPU-Z; it should report 6400 MT/s, CL52-52-52 timings and 1.10 V. ECC and registered status will also be shown if the platform supports those features.

Does the box contain only the memory stick or are cables or brackets included?

Only the 32 GB DDR5-6400 RDIMM is supplied. No cables, brackets, heatsinks or additional hardware are included in the package.
