512GB DDR4 3200 ECC RDIMM kit

This 512GB kit contains four 128GB DDR4 3200 registered DIMMs with ECC and a CAS latency of CL22. It is built for ThinkMate TWX-QS8 tower servers that require 4Rx4 registered memory. The modules operate at 1.2V and use major OEM chips from Samsung, Micron or Hynix.

Check ThinkMate TWX-QS8 compatibility

Verify that your server is a TWX-QS8-14E3 or TWX-QS8-24E3 model before ordering. The motherboard must support 4Rx4 registered DDR4 RDIMMs at 3200MT/s and accept a total of 512GB across four slots. Consult the system manual for approved population rules and any BIOS version requirements.

Thermals noise and power in normal use

Each module runs at 1.2V without a heat spreader, relying on server chassis airflow for cooling. Registered ECC RDIMMs draw modest power per DIMM and produce no audible noise since they have no moving parts. Ensure the server fans provide adequate airflow across the memory slots for sustained workloads.
