System-Specific 256 GB DDR5 Kit

This 256 GB kit contains two 128 GB DDR5-4800 ECC registered DIMMs built for ThinkMate HDX-XH24-52S4 high-density servers. Each module runs at 1.1 V with CL40 latency and a 4Rx4 organisation. The memory is validated for the target platform to deliver stable operation in enterprise workloads.

DDR5-4800 Registered ECC Limits

The DDR5-4800 (PC5-38400) interface provides a fixed transfer rate and registered buffering that reduces electrical load on the memory controller. ECC corrects single-bit errors, but registered DIMMs cannot be mixed with unbuffered modules and require a motherboard chipset that supports registered ECC operation.

Compatibility Check Before Ordering

Verify that your ThinkMate HDX-XH24-52S4 server accepts 288-pin DDR5 RDIMMs at 1.1 V and supports 4Rx4 ranks at the full 256 GB capacity. Confirm the firmware revision enables the rated 4800 MT/s speed and that the memory population rules allow two 128 GB modules in the intended slots.
