Capacity and compatibility

This NEMIX RAM kit provides 192GB of DDR4 memory across six 32GB RDIMM modules. It is built for THINKMATE RAX-XS4-21S1-10G, RAX-XS4-11S1-10G and RAX-XH2-11S3 rackmount servers that require registered ECC memory. The 2Rx8 organisation and 288-pin form factor match the platform's registered DIMM slots. Builders needing unbuffered UDIMMs or non-ECC memory for desktop platforms cannot use this kit.

Sustained-load behaviour

Modules run at DDR4 3200 (PC4-25600) with a CAS latency of CL22 and operate at 1.20V. Registered buffering and on-die ECC correct single-bit errors during continuous operation, maintaining data integrity for virtualisation, database and compute workloads. Major OEM Samsung, Micron or Hynix chips are stress-tested under load before shipment. Systems limited to lower memory speeds or fewer populated channels will not reach the rated throughput.

Thermals noise and power

The modules have no heat spreaders, relying on server chassis airflow for cooling. At 1.20V the kit draws minimal power per DIMM, keeping thermal contribution low in densely populated racks. No moving parts mean zero acoustic noise from the memory itself. Installations in enclosures with restricted airflow should verify that case fans provide sufficient velocity across the bare PCBs.

Questions about this item

How much power does each 32GB DDR4 3200 module draw at 1.2V when the server runs continuously?

Each module operates at 1.2V standard DDR4 voltage. Registered ECC RDIMMs typically draw a few watts per stick under load; total kit consumption scales with all six modules populated.

What must the ThinkMate rackmount already have to accept this 6×32GB RDIMM kit?

The server needs DDR4 RDIMM slots that support 3200MHz registered ECC memory and a memory controller able to address 192GB across six 2Rx8 modules.

Will this CL22 3200MHz kit run stably alongside slower DDR4 DIMMs already installed in the ThinkMate?

The memory controller will down-clock all populated slots to the lowest common speed and highest latency, so older DDR4 RDIMMs will work but at reduced performance.
