ThinkMate HDX Server Memory Upgrade

This 16 GB DDR5 4800 MHz ECC RDIMM module is built for ThinkMate HDX-XH24-52S4 high-density servers. Registered buffering and on-die error correction protect data integrity in multi-socket workloads. Single-rank 1Rx8 organisation keeps electrical loading low for dense DIMM populations. It installs in standard 288-pin DDR5 slots.

DDR5 4800 Registered DIMM Constraints

Registered DIMMs require a server chipset that supports buffered memory; they will not function in consumer desktop platforms. The JEDEC DDR5 4800 baseline caps transfer rate at 38 400 MB/s per module. CL40 latency and 1.10 V operation are fixed at this speed grade. Mixing ranks or speeds forces the channel to the slowest common denominator.

Replaces Lower-Capacity or Non-ECC Modules

Swapping 8 GB RDIMMs or unbuffered ECC UDIMMs for this 16 GB registered kit doubles per-slot capacity while adding register-driven signal integrity. The upgrade pays off when virtual machine density or in-memory database size exceeds current physical memory. Systems already populated with 16 GB RDIMMs at 4800 MHz gain no throughput benefit from this module.

Questions about this item

Should I pick the 1Rx8 version or look for a different rank?

This module is a single 16 GB stick built as 1Rx8, so the rank is fixed; choose it when your Thinkmate HDX-XH24-52S4 server needs exactly one 16 GB registered DIMM.

What does the 4800 MT/s rating deliver in the Thinkmate server?

At DDR5 4800 the module runs at the platform's native speed, giving 38 400 MB/s peak bandwidth per DIMM with CL40 latency at 1.10 V.

How does the 288-pin DDR5 RDIMM interface limit the memory subsystem?

The registered 288-pin DDR5 interface caps each slot at 4800 MT/s and requires ECC registered modules, so this 16 GB stick fits that exact electrical and mechanical slot.
