Targeted Server Memory

This 128GB kit delivers DDR5 4800 registered ECC memory in two 64GB modules built for the Thinkmate GPX-XH8-22S4-8GPU server. The 2Rx4 organisation and CL40 timing match the platform's qualified configuration for GPU-optimised workloads.

Registered DDR5 Build

Each 288-pin RDIMM operates at 1.1V with on-board register buffering to stabilise heavy multi-channel populations. Samsung, Micron or Hynix major-OEM chips are stress-tested under load to ensure reliability in continuous server duty.

Ready-to-Install Kit

The matched pair ships as a single 128GB package so both modules share identical date codes and validation records. No additional cables, brackets or software are included; installation follows the system owner's manual.

Questions about this item

What DDR5 speed and CAS latency does this 288-pin RDIMM kit run at?

The kit operates at DDR5 4800 with a CAS latency of CL40, delivering PC5-38400 bandwidth across both 64GB modules.

Does this ECC registered memory require a 288-pin DDR5 RDIMM slot and 1.1 V power?

Yes, each 64GB module uses the standard 288-pin DDR5 RDIMM form factor and runs at 1.10 V, so the server must provide registered DIMM slots at that voltage.

How do I install the two 64GB sticks in the Thinkmate GPX-XH8-22S4-8GPU, and what step is often missed?

Power down, open the chassis, align each module's key notch with the 288-pin slot, press firmly until both ejector clips lock, then verify the BIOS recognises the full 128GB at 4800 MT/s — skipping the BIOS check is the common oversight.
