ThinkMate HDX-XH24-52S4 memory kit

This 1.5 TB DDR5 4800 kit contains twelve 128 GB registered ECC RDIMMs validated for ThinkMate HDX-XH24-52S4 high-density servers. It targets administrators who need maximum memory capacity in a supported configuration.

12-module registered ECC kit

The kit delivers twelve matched 4Rx4 modules at 1.1 V with CL40 latency, eliminating the risk of mixing modules from different batches. ECC and registered buffering protect data integrity under sustained server workloads.

1.5 TB DDR5 4800 4Rx4 capacity

The total 1.5 TB capacity at DDR5 4800 speed with 4Rx4 organisation determines whether the server can address the required memory density; systems that cannot support 128 GB RDIMMs or 4Rx4 ranks will not accept this kit.

Questions about this item

Will the 128GB DDR5 modules need any firmware updates or periodic reseating after installation?

The modules are stress-tested before shipping and carry a lifetime replacement warranty; no firmware updates or scheduled reseating are required once they are seated in the 288-pin slots.

What thermal limit appears first when all twelve 4Rx4 modules run at 4800 MT/s continuously?

With no heat spreaders fitted, the DRAM junction temperature will reach its throttling threshold before the 1.1 V power envelope becomes a constraint.

How much power does the full 1.5 TB kit draw at 1.10 V when the server runs 24/7?

The kit operates at 1.10 V DDR5 standard voltage; total power scales with active rank count and data rate, so sustained draw depends on the workload pattern.
