512 GB DDR5 ECC RDIMM kit

This 512 GB kit contains eight 64 GB DDR5 4800 registered DIMMs built for the Thinkmate GPX-XH20-28S4-8HGX GPU-optimised server. ECC and registered operation protect data integrity in mission-critical workloads. The modules run at 1.1 V and carry a CL40 latency rating.

288-pin registered form factor

Each stick uses the standard 288-pin DDR5 RDIMM layout with 2Rx4 organisation and no heat spreader. The registered buffer reduces electrical load on the memory controller, allowing all eight slots to be populated reliably. Installation follows the server motherboard’s documented slot population rules.

DDR5 4800 platform limit

The memory operates at the DDR5 4800 (PC5 38400) baseline speed defined by the platform. Higher data rates are not supported by this server configuration. Capacity is fixed at 512 GB across the eight modules; expansion beyond the populated slots is not possible.

Questions about this item

What speed and data rate does the DDR5 4800 PC5-38400 specification deliver?

The kit runs at 4800 MT/s with a PC5-38400 rating, providing 38400 MB/s peak transfer per module.

What physical slot and module dimensions are required to install these 288-pin DDR5 RDIMMs?

Each module uses the standard 288-pin DDR5 RDIMM form factor and fits a 288-pin DDR5 server DIMM slot.

How are the eight 64 GB modules installed in the ThinkMate GPX-XH20-28S4-8HGX, and what step is often missed?

Populate all eight slots following the motherboard's channel population guide; the step often missed is enabling ECC and registered mode in BIOS after installation.
