Server-grade ECC RDIMM kit

This NEMIX RAM kit delivers 64 GB of DDR4 3200 memory in four 16 GB registered DIMMs. ECC and registered buffering protect data integrity in Thinkmate rackmount servers such as the RAX-XN24 and XT24 series. The modules run at 1.2 V with CL22 latency and use major OEM chips from Samsung, Micron or Hynix.

Thermals and power in normal use

Operating at the standard 1.2 V DDR4 voltage, the modules draw minimal power and produce little heat. No heat spreaders are fitted, so airflow through the server chassis handles cooling silently. Registered buffering reduces electrical load on the memory controller, contributing to stable operation under sustained workloads.

Upgrade path and when it matters

The kit replaces lower-capacity or non-ECC DIMMs in compatible Thinkmate platforms, adding error correction and higher density for virtualisation or database tasks. It is not suited for desktop boards that require unbuffered memory or for systems limited to speeds below DDR4 3200.

Questions about this item

How do I install the 288-Pin DDR4 RDIMM modules into my THINKMATE server?

Power down the server and open the chassis. Locate the DDR4 DIMM slots on the motherboard. Align the notch on each 288-Pin module with the slot key, insert vertically, and press firmly until the retention clips click. Populate slots per the server manual for quad-channel operation.

What maintenance or replacement will the 2Rx8 ECC RDIMM kit need over time?

The modules have no moving parts and require no scheduled maintenance. ECC corrects single-bit errors on the fly. If a module fails, the lifetime replacement warranty covers a swap. Keep firmware updated and monitor system logs for corrected error counts.

At what point does the CL22 1.2V DDR4 3200 kit hit its limit under sustained load?

The first limit is the JEDEC-rated DDR4 3200 MT/s data rate and CL22 latency ceiling. Under continuous heavy workloads the registered buffer and ECC logic add fixed overhead, so throughput plateaus at the PC4-25600 specification regardless of cooling.
