32 GB DDR5 ECC RDIMM for servers

This 32 GB DDR5 4800 CL40 registered DIMM is built for Kingston-compatible server and workstation platforms. It delivers error-correcting code protection and registered signalling for stable operation in multi-module configurations. The module suits IT professionals who need reliable capacity expansion in enterprise environments.

Check motherboard RDIMM support

Verify that your system accepts 288-pin DDR5 registered memory and that the memory controller supports 1Rx4 organisation at 4800 MT/s. Confirm the maximum module capacity per slot and the required population order in the platform documentation before ordering. Registered DIMMs will not work in platforms limited to unbuffered memory.

Runs at 1.1 V with no heat spreader

The module operates at the standard DDR5 voltage of 1.10 V and carries no integrated heat spreader. In normal server chassis airflow the bare PCB runs within thermal limits without adding acoustic load. Power draw scales with the single-rank 32 GB density and the CL40 timing at 4800 MT/s.

Questions about this item

Does the 32GB DDR5 4800 CL40 ECC RDIMM come as a single module or a kit, and is any mounting hardware required?

The package contains one 32GB 288-PIN DDR5 RDIMM module. No additional mounting hardware is needed; the module installs directly into a compatible RDIMM slot.

How do I choose between the Kingston KSM48R40BS4TMI-32HAI and KSM48R40BS4TMI-32MDI compatible versions?

Both part numbers share the same 32GB capacity, DDR5 4800 speed, CL40 latency, 1.10V voltage, 1Rx4 rank and ECC registered design. Select the part number that matches your system's qualified vendor list.

What does the DDR5 4800 rating mean for actual throughput in a registered server board?

The module operates at 4800 MT/s with CL40 timing at 1.10V, delivering PC5-38400 rated bandwidth when the platform runs the memory at its native DDR5 4800 speed.
