64 GB DDR5 ECC RDIMM for Thinkmate servers

This 64 GB DDR5 4800 registered DIMM adds ECC-protected capacity to Thinkmate GPX-XH20-28S4-8HGX GPU-optimised servers. It targets administrators who need single-module density for high-core-count workloads. The 2Rx4 organisation and 1.1 V operation match the platform's registered memory requirements.

Tool-free DIMM installation

The 288-pin module seats in the standard DDR5 RDIMM slots without cabling or brackets; the registered buffer handles address and command signals for the server chipset. Builders must populate slots in the order specified by the Thinkmate service manual to keep memory channels balanced. Mixing ranks or speeds across channels will prevent the system from posting.

Steady throughput under continuous ECC workloads

Samsung, Micron or Hynix DRAM chips are stress-tested under sustained load before shipping, so error correction remains active during long render, simulation or database jobs. The CL40 latency and PC5-38400 bandwidth hold constant without thermal throttling because the module operates at the rated 1.1 V. Workloads that exceed 64 GB per channel will still require additional DIMMs.

Questions about this item

How do I confirm the module is running at DDR5 4800 with CL40 after installation?

Enter the system BIOS or use a hardware-information utility to verify the memory speed reads 4800 MT/s and the CAS latency shows 40.

What comes in the package and do I need any extra parts?

The box contains one 64 GB 288-pin DDR5 RDIMM; no additional components are required for installation in a compatible server.

Which capacity and rank should I choose for the ThinkMate GPX-XH20-28S4-8HGX?

This module provides 64 GB in a 2Rx4 configuration, matching the server's supported DDR5 4800 ECC RDIMM specification.
