Purpose-built server upgrade

This NEMIX RAM kit delivers 32 GB of DDR5 ECC registered memory in a matched pair of 16 GB modules. It is engineered specifically for the Thinkmate GPX-XH8-22S4-8GPU GPU-optimised server platform. The registered design and error-correcting code protect data integrity in mission-critical workloads.

Registered ECC at DDR5 4800

Each module runs at 4800 MT/s (PC5-38400) with CL40 latency at 1.10 V. The 1Rx8 organisation and 288-pin RDIMM form factor ensure the electrical load matches the server’s memory controller requirements. Samsung, Micron or Hynix major-OEM chips are used throughout the kit.

For Thinkmate GPX-XH8-22S4-8GPU owners

This kit suits administrators upgrading that exact server model with validated, stress-tested modules. Builders targeting other platforms, desktop boards or unbuffered memory should look elsewhere because the registered ECC interface and system-specific validation will not function in those environments.

Questions about this item

What does DDR5 4800 CL40 mean for actual throughput in a ThinkMate GPX-XH8-22S4-8GPU server?

DDR5 4800 runs at 4800 MT/s with CL40 latency; the registered buffer adds one cycle, so real-world bandwidth depends on the platform's memory controller and channel population.

How does the PC5-38400 rating translate to usable bandwidth on this registered ECC kit?

PC5-38400 is the module's peak transfer spec; sustained bandwidth in the ThinkMate server will be lower and varies with CPU, BIOS settings and number of populated channels.

Will these 288-pin RDIMMs fit the ThinkMate GPX-XH8-22S4-8GPU memory slots without a heat spreader?

Yes, the modules are standard 288-pin DDR5 RDIMMs with no heat spreader, matching the ThinkMate server's DIMM slots; verify maximum module height in the system manual if space is tight.
