Server Memory Kit

This NEMIX RAM kit delivers 1.5TB of DDR5 memory across twelve 128GB registered DIMMs. It is built for THINKMATE GPX-QH24-24E4-8GPU and GPX-QH14-28E4-8HGX GPU-optimised servers that require ECC RDIMM modules. The 4Rx4 organisation and CL40 latency support dense multi-socket configurations.

Platform Verification

Confirm that your THINKMATE server model matches the GPX-QH24-24E4-8GPU or GPX-QH14-28E4-8HGX designation before ordering. Verify the motherboard accepts 288-pin DDR5 RDIMMs at 4800MT/s with 1.10V operation. Check the system documentation for maximum supported capacity per channel and total DIMM slots available.

Build Integration

Twelve modules populate all slots in a 12-channel arrangement, freeing no additional bays for further memory expansion. The registered design reduces electrical load on the memory controller, enabling stable operation at full capacity. No heat spreaders are fitted, so ensure chassis airflow meets the server vendor's thermal guidelines for dense memory configurations.

Questions about this item

What comes in the 1.5TB kit and is anything else required for installation?

The kit contains twelve 128GB DDR5 4800 ECC RDIMM modules. No additional parts are required; install directly into the server's 288-pin DDR5 slots.

How do I choose between the 12x128GB kit and smaller capacities for the THINKMATE GPX-QH24-24E4-8GPU?

The 12x128GB kit fills all 12 channels for maximum bandwidth. Choose a smaller kit only if you plan to populate fewer channels or need room for future expansion.

What does the CL40 latency mean when the modules run at DDR5 4800 in a registered server?

CL40 is the CAS latency at 4800 MT/s. Registered ECC modules add one cycle of buffering, so the effective latency in a real workload is CL40 plus the register delay.
