System-Specific Server Memory Kit

This NEMIX RAM kit provides 768 GB of DDR4 ECC registered memory across six 128 GB modules. It is built for the Thinkmate GPX-XT6-24S3-8NVLink server platform where registered DIMMs are required. The modules use a 4Rx4 organisation and operate at 1.20 V.

DDR4 3200 Registered Interface Limits

The DDR4 3200 standard caps transfer rates at 3200 MT/s with a CL22 latency at this density. Registered signalling adds one cycle of buffering, which stabilises heavy loads but prevents use in platforms that expect unbuffered DIMMs. ECC correction handles single-bit errors but cannot repair multi-bit failures.

Pre-Installation Compatibility Checks

Verify that the Thinkmate GPX-XT6-24S3-8NVLink has six free 288-pin DDR4 RDIMM slots and that its BIOS supports 128 GB 4Rx4 modules at 3200 MT/s. Confirm the memory population rules for the specific CPU configuration installed. This kit is not for systems requiring unbuffered UDIMMs or lower-density ranks.

Questions about this item

Should I choose the 768 GB kit with six 128 GB modules or a smaller capacity for my THINKMATE GPX-XT6-24S3-8NVLINK?

The 768 GB kit fills all six channels with 128 GB 4Rx4 modules, giving maximum capacity and bandwidth for GPU-optimised workloads; choose a smaller kit only if your application does not need the full 768 GB.

What does the DDR4 3200 PC4-25600 rating deliver once installed in the server?

Each module runs at 3200 MT/s with CL22 latency at 1.20 V, providing the rated PC4-25600 transfer rate per channel when the CPU memory controller operates at that speed.

How does the 288-pin ECC RDIMM interface affect usable performance?

The 288-pin registered DIMM interface with ECC and 4Rx4 organisation enables error correction and signal buffering, letting the memory controller drive all six modules at 3200 MT/s without exceeding electrical load limits.
