576GB DDR5 ECC RDIMM kit

This 576GB kit contains six 96GB DDR5 4800 CL40 registered DIMMs built for Thinkmate GPX-XH20-28S4-8HGX GPU-optimised servers. The modules operate at 1.10V and use a 2Rx8 organisation with ECC for data integrity. They target administrators who need maximum memory capacity in qualified server platforms.

Replaces lower-capacity DDR5 RDIMMs

Upgrading from smaller DDR5 registered modules is worthwhile when workloads exceed the current memory ceiling and the server board supports 96GB dual-rank DIMMs. The jump makes sense for virtualisation hosts, large in-memory databases or GPU compute nodes that can address the full 576GB. Systems limited to lower per-slot densities or slower speeds will not benefit.

Limited to DDR5 4800 registered ECC

The DDR5 4800 interface caps peak bandwidth at the PC5-38400 rate and requires a motherboard qualified for 288-pin registered ECC DIMMs at 1.10V. Unbuffered or non-ECC boards cannot use these modules. Latency is fixed at CL40 and the kit does not support higher data rates or overclocking profiles.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the memory slots in a ThinkMate GPX-XH20-28S4-8HGX server?

Yes, the 288-pin DDR5 RDIMM form factor matches the DIMM slots on the ThinkMate GPX-XH20-28S4-8HGX GPU-optimised server.

What is the correct order to install the six 96GB modules so the registered ECC memory initialises properly?

Populate the slots in the sequence shown in the server manual, usually filling one channel per CPU first; skipping a channel or mixing ranks prevents the registered buffer from training at 4800 MT/s.

When should the 2Rx8 Samsung, Micron or Hynix DRAM chips be replaced if ECC correctable errors start rising?

Replace modules once the platform logs show a sustained climb in correctable error counts, indicating the 2Rx8 DRAM is degrading beyond ECC recovery.
