System-specific DDR5 memory kit

This 384GB kit contains four 96GB DDR5 4800 CL40 ECC registered DIMMs built for the Thinkmate HDX-XH24-52S4 server. It targets IT teams upgrading that platform to its maximum supported capacity. The modules operate at 1.1V and use a 288-pin interface.

ECC registration and quad-rank density

Registered buffers and on-die ECC protect data integrity under sustained multi-threaded workloads. The 2Rx8 organisation packs 96GB into each module so the four slots deliver 384GB without exceeding the system's slot count. No heat spreaders are fitted, matching the chassis airflow design.

96GB per module density requirement

The HDX-XH24-52S4 only reaches 384GB when every slot holds a 96GB RDIMM; smaller modules leave total capacity below the platform maximum. Buyers needing less than 384GB should choose a lower-density kit instead.

Questions about this item

Will the 96 GB 2Rx8 RDIMM modules need any firmware updates or heat-spreader retrofits as the server ages?

The modules ship without heat spreaders and run at the standard 1.1 V; no firmware updates or spreader retrofits are required for the DDR5 4800 specification.

Which limit appears first when the 384 GB kit runs sustained loads in the Thinkmate HDX-XH24-52S4?

The registered DDR5 4800 CL40 timing at 1.10 V sets the bandwidth ceiling before thermal or power limits are reached.

How much extra heat and power does the 4-module 384 GB kit add when the server runs all day?

Four 96 GB 2Rx8 RDIMMs at 1.1 V draw minimal incremental power and produce only modest heat compared with the server’s total thermal budget.
