Thinkmate Server Upgrade

This 128GB kit provides two 64GB DDR4 3200 registered ECC modules built for Thinkmate HDX series servers. IT teams use it to expand memory capacity in qualified high-density platforms. The modules operate at 1.2V with CL22 latency and 4Rx4 organisation. They are validated for the specific systems listed in the compatibility data.

288-Pin RDIMM Integration

Each module fits a standard 288-pin DDR4 RDIMM slot and requires a motherboard that supports registered ECC memory. The registered buffer reduces electrical load on the memory controller, allowing higher total capacities per channel. No heat spreader is included, so airflow in the server chassis must be sufficient. Installation follows the server manufacturer's documented procedure.

128GB Registered ECC Capacity

The dual-rank 4Rx4 configuration delivers 128GB total across two modules, suited for virtualisation, database and compute workloads that benefit from large memory footprints. ECC protection corrects single-bit errors to maintain data integrity under sustained load. Workloads exceeding this capacity or requiring higher speeds will need additional modules or a different platform.

Questions about this item

How does the CL22 latency affect performance under sustained server workloads?

CL22 CAS latency at DDR4 3200 sets the minimum cycle delay for each memory access, which becomes the primary timing bottleneck during continuous read/write operations on this registered ECC kit.

What thermal or power behaviour should be expected when the modules run at 1.2 V all day?

Operating at 1.2 V without heat spreaders, the 4Rx4 registered DIMMs rely on server chassis airflow; power draw stays at standard DDR4 registered levels and noise is determined by system fans, not the memory itself.

Which Thinkmate server models must the buyer already own for this 288-pin RDIMM kit to function?

This 128 GB kit (2 × 64 GB) is validated for Thinkmate HDX-QT24-52E3, HDX-QN24-52E3 and HDX-QT24-32E3 high-density servers that accept DDR4 3200 ECC RDIMMs.
