64 GB DDR5 ECC RDIMM for ThinkMate servers

This 64 GB DDR5 module runs at 4800 MT/s with CL40 latency and 1.1 V operation. It is a registered ECC RDIMM built with 2Rx4 organisation for ThinkMate GPX-QH12-12E4-2GPU GPU-optimised servers. The part targets administrators who need single-module capacity expansion in validated platforms.

288-pin registered design with major OEM chips

The module uses a 288-pin DDR5 RDIMM form factor without a heat spreader. Chips are sourced from Samsung, Micron or Hynix to meet enterprise qualification standards. Registered buffering and on-die ECC protect data integrity under sustained workloads in the qualified ThinkMate chassis.

Replaces lower-capacity or non-ECC DDR5 DIMMs

Upgrading from smaller registered modules or unbuffered memory adds 64 GB per slot and restores ECC protection. The jump is worthwhile when the server board supports 2Rx4 registered DDR5 at 4800 MT/s and the application demands maximum per-slot density with error correction.

Questions about this item

What DDR5 speed does this 4800 MT/s RDIMM run at when installed in a THINKMATE GPX-QH12-12E4-2GPU server?

The module is rated DDR5 4800 (PC5-38400) and will operate at that data rate provided the server’s memory controller supports 4800 MT/s.

Does the 288-pin ECC registered DIMM fit the memory slots on the THINKMATE GPX-QH12-12E4-2GPU?

Yes, the 288-pin DDR5 RDIMM form factor matches the server’s DIMM sockets; the module is 1.10 V, 2Rx4, CL40 and has no heat spreader.

What is the correct way to seat this registered ECC module and which step is often missed?

Align the notch with the slot key, press straight down until both retention clips click, then verify in BIOS that all 64 GB are recognised at 4800 MT/s with ECC active.
