System-Specific DDR5 ECC RDIMM Kit

This NEMIX RAM kit delivers 64 GB of DDR5 memory in a matched set of four 16 GB registered DIMMs. Each module runs at 4800 MT/s with CL40 latency at 1.10 V and includes on-die ECC for error correction. The 288-pin RDIMM form factor is validated for the ThinkMate GPX-WS-740RTP7 workstation platform.

Workstation Builders Needing Registered ECC

IT teams upgrading or servicing the specified ThinkMate workstation gain a tested, single-rank 1Rx8 configuration that meets the platform’s registered memory requirement. Systems that require unbuffered UDIMMs, non-ECC modules, or a different pin count cannot use this kit.

Four-Module Kit Simplifies Population

The package supplies all four DIMMs in one box, so the memory controller sees a balanced quad-channel population without mixing part numbers. No heat spreaders are included, leaving the modules at standard height for dense server chassis. No additional software, cables or accessories are bundled.

Questions about this item

Does my workstation need open DDR5 RDIMM slots to install this 4x16GB kit?

Yes, the kit contains four 288-pin DDR5 RDIMM modules and requires four available registered DIMM slots in the THINKMATE GPX-WS-740RTP7.

Can I add these CL40 ECC RDIMMs to existing DDR5 memory in the same system?

Mixing is possible only if the installed modules are also DDR5 ECC RDIMMs at 4800 speed and 1.10V; otherwise the system will default to the slowest common settings or fail to boot.

How do I confirm the full 64GB is detected at 4800 MT/s with ECC active after installation?

Enter the BIOS or UEFI and check the memory information screen — it should show 64GB total, 4800 MT/s operating speed, CL40 timings and ECC enabled.
