32GB DDR5 4800 ECC Registered Module

This 32GB DDR5 4800 ECC Registered RDIMM targets server and workstation platforms that require error-correcting memory. The registered design adds a buffer to reduce electrical load on the memory controller. Supermicro specifies compatibility with DDR5 ECC Registered server motherboards.

Capacity and headroom for server workloads

A single 32GB module provides substantial capacity for virtualization, database caching and compute-intensive tasks. Dual-rank 2Rx8 organisation helps populate channels efficiently. Workloads exceeding the installed module count will require additional DIMM slots.

DDR5 4800 interface practical limits

The module operates at 4800 MT/s with CL40 latency and 1.10V voltage. Bandwidth scales with the number of populated channels and the memory controller capabilities of the host platform. Maximum supported memory per system depends on the specific motherboard and processor specifications.

Questions about this item

Will this 4800 MT/s DDR5 RDIMM downclock to match slower DDR5 modules already installed?

Yes, DDR5 modules automatically negotiate the lowest common speed, so this 4800 MT/s kit will run at the speed of any slower DDR5 DIMMs sharing the channel.

How can I confirm the module is running at 4800 MT/s with ECC active after installation?

Check the BIOS memory information screen or run a tool such as dmidecode; it will show 4800 MT/s, CL40, 1.10 V and ECC registered status for each DIMM.

Does the box include a heat spreader or any mounting hardware, or must I buy those separately?

The module has no heat spreader and no extra hardware is included; only the RDIMM itself is supplied.
