System-specific DDR5 ECC RDIMM kit

This 128 GB kit contains two 64 GB registered DDR5 modules built for the Thinkmate GPX-XH20-28S4-8HGX server. ECC and registered buffering protect data integrity in multi-GPU workloads. The modules run at 1.1 V without heat spreaders, relying on chassis airflow.

Registered 2Rx4 organisation at 4800 MT/s

Each module uses a 2Rx4 layout and operates at DDR5 4800 (PC5-38400) with CL40 latency. Registered signalling reduces electrical load on the memory controller, allowing the full two-module population. This specification determines whether the kit matches the server's qualified vendor list.

Sustained throughput under continuous GPU compute

Stress testing under load verifies stability for extended training or inference runs. Registered buffering and ECC correction maintain signal quality when all channels are saturated. The 1.1 V operating point keeps power draw predictable during prolonged high-bandwidth access.

Perguntas sobre este artigo

What does the 4800 MT/s rating mean once these modules are installed in the ThinkMate server?

The server memory controller runs the kit at its rated 4800 MT/s, delivering PC5-38400 bandwidth for GPU-optimised workloads.

How does the DDR5 ECC RDIMM interface limit real-world throughput?

Registered DDR5 with ECC adds one cycle of buffering and error correction, capping sustained throughput at the PC5-38400 line rate.

Will the 288-pin RDIMM modules fit the ThinkMate GPX-XH20-28S4-8HGX memory slots?

Yes, the 288-pin DDR5 RDIMM form factor matches the server's DIMM sockets exactly.
