768GB DDR5 ECC RDIMM kit for Thinkmate servers

This 768GB kit contains twelve 64GB DDR5 4800 registered DIMMs built with ECC for error correction. It is designed for Thinkmate GPX-QH24-24E4-8GPU and GPX-QH14-28E4-8HGX GPU-optimised servers that require registered memory. The modules operate at 1.1V with a CL40 latency.

Twelve-module kit fills twelve slots at once

The package delivers a complete 768GB configuration in a single shipment, removing the need to source individual sticks. Each 288-pin RDIMM uses a 2Rx4 organisation and major OEM DRAM from Samsung, Micron or Hynix. No heat spreaders are included, so airflow clearance follows the server chassis design.

Registered ECC DDR5 at 4800 MT/s

The registered buffer and on-die ECC protect data integrity in multi-GPU compute workloads. Speed is fixed at DDR5 4800 (PC5-38400) with CL40 timing. Buyers needing unbuffered UDIMMs, lower latency ratings or non-ECC modules cannot use this kit.

Questions about this item

Do the 12 modules include heat spreaders for long-term cooling?

The 12 DDR5 RDIMM modules ship without heat spreaders; airflow from the server chassis provides cooling for the 1.10 V memory kit.

At 4800 MT/s CL40, which limit appears first during sustained GPU workloads?

The registered 2Rx4 DDR5 4800 modules run at the JEDEC 4800 speed ceiling, so memory bandwidth saturates before latency becomes the bottleneck.

How much power and heat does the 768 GB kit add when the server runs all day?

At 1.10 V across twelve 64 GB RDIMMs, the kit draws roughly 84 W, adding modest heat that standard server airflow handles.
