Capacity & Form Factor

This is a 16GB DDR5 registered DIMM built for Thinkmate GPX-XH8-22S4-8GPU servers. It operates at 4800MHz with a CL40 latency and 1.10V voltage. The module uses a 1Rx8 organisation and fits standard 288-pin DDR5 slots. ECC and registered buffering support data integrity in multi-socket platforms.

ECC & Registered Operation

Error-correcting code detects and corrects single-bit errors during operation. Registered buffering reduces electrical load on the memory controller. Together they allow larger memory populations per channel without signal degradation. No heat spreader is included, so airflow across the bare PCB must be maintained by the server chassis.

Enterprise Server Upgrades

Suited for IT teams expanding memory in validated Thinkmate GPU-optimised servers. Buyers needing unbuffered UDIMMs for workstation boards should look elsewhere. Systems requiring higher densities per slot or lower latencies than CL40 will need different modules.

Questions about this item

Will the RDIMM module itself need replacement or servicing after deployment?

The module is a solid-state component with no moving parts and no user-serviceable elements, so it does not require scheduled maintenance or planned replacement.

What limit appears first when the memory runs continuously at 4800 MT/s?

The registered buffer and CL40 latency govern the maximum sustained throughput, so the command-and-address timing budget becomes the first bottleneck under constant load.

How much heat and power does a single 16 GB stick draw at 1.1 V all day?

Operating at 1.1 V with no heat spreader, the module relies on chassis airflow to dissipate its low-power DDR5 profile during continuous operation.
