1 TB DDR5-4800 ECC RDIMM kit for Thinkmate GPU

This NEMIX RAM kit delivers 1 TB of DDR5 4800 registered ECC memory across eight 128 GB modules. It is built for Thinkmate GPX-QH24-24E4-8GPU and GPX-QH14-28E4-8HGX GPU-optimised servers that require registered DIMMs with error correction.

Suits administrators scaling GPU-dense servers

Buyers who need unbuffered UDIMMs, non-ECC modules or speeds above DDR5 4800 will not be served by this kit. Systems limited to fewer than eight DIMM slots or to lower maximum capacities should select a different configuration.

4Rx4 organisation on 288-pin DDR5 RDIMM

Each module uses a 4Rx4 layout at 1.10 V with CL40 latency. The rank structure and registered interface determine whether the server's memory controller can populate all eight slots at the rated speed.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit in the THINKMATE GPX-QH24-24E4-8GPU server?

Yes, the kit is built for that exact model and the GPX-QH14-28E4-8HGX, using the standard 288-pin DDR5 RDIMM form factor required by those platforms.

What is the correct population order for the eight 128 GB sticks?

Fill the slots per the server manual — typically one module per channel first, then add the second rank; the 4Rx4 organisation means each stick presents four ranks, so follow the channel map to avoid a POST error.

When should the modules be replaced in a 24/7 workload?

DDR5 ECC RDIMMs have no scheduled replacement interval; swap a stick only if the system logs correctable errors that exceed the platform threshold or a module fails diagnostics.
