192GB DDR5 ECC RDIMM kit for ThinkMate GPU servers

This 192GB kit delivers two 96GB registered DDR5 modules rated at 4800 MT/s with CL40 latency. It is built for ThinkMate GPX-QH24-24E4-8GPU and GPX-QH14-28E4-8HGX GPU-optimised servers that require ECC registered memory. The modules operate at 1.1V and use a 2Rx8 organisation on 288-pin RDIMM form factor.

Sustained-load behaviour

Error-correcting code and registered buffering maintain data integrity during continuous GPU compute workloads. The 4800 MT/s speed and CL40 timing provide stable throughput for multi-GPU training or inference tasks. Major OEM Samsung, Micron or Hynix chips are stress-tested under load to ensure reliability in 24/7 server environments.

Verify ThinkMate server model and DDR5 slot count

Confirm your system is a ThinkMate GPX-QH24-24E4-8GPU or GPX-QH14-28E4-8HGX before ordering. The motherboard must support DDR5 RDIMM modules at 4800 MT/s and provide enough 288-pin slots for two 96GB sticks. Check the vendor documentation for maximum memory per channel and any population rules for 2Rx8 registered DIMMs.

Questions about this item

How much heat and power does the 1.1V DDR5 4800 kit add when the ThinkMate GPU server runs all day?

Each module operates at 1.1V with no heat spreader, so the 2Rx8 registered DIMMs draw minimal power and rely on the server chassis airflow for cooling during continuous operation.

What must the ThinkMate GPU-optimised server already have to accept this 192GB kit?

The system needs free 288-pin DDR5 RDIMM slots and a motherboard qualified for PC5-38400 ECC registered memory running at CL40 latency.

Will the CL40 2Rx8 registered modules work alongside any older DDR5 RDIMMs still installed in the same ThinkMate chassis?

Mixing ranks or latencies is not recommended; for stable ECC operation the server should be populated with identical 96GB 2Rx8 CL40 modules across all channels.
