512GB DDR5 ECC RDIMM Kit

This 512GB kit contains sixteen 32GB DDR5 4800 CL40 registered ECC modules built for THINKMATE SuperServer 421GE-TNRT and 421GE-TNRT3 systems. It targets IT professionals who need maximum memory capacity for virtualization, databases or high-performance computing workloads on these specific platforms.

Tool-less DIMM installation

Modules insert vertically into the server's 288-pin DDR5 slots and lock with the board's native ejectors; no extra tools are required. The main risk is mixing registered ECC RDIMMs with unbuffered or LRDIMM types, which prevents the system from posting. Always populate all sixteen slots identically and follow the motherboard manual's channel population order to avoid training failures.

Suited for THINKMATE 421GE-TNRT/TNRT3 upgrades

This kit fits administrators expanding compatible THINKMATE SuperServers to the full 512GB supported configuration. It is not for workstations or consumer motherboards that lack registered ECC support, nor for any server model outside the listed THINKMATE part numbers. Buyers who need a different capacity, speed or form factor should verify their platform's qualified vendor list before purchasing.

Questions about this item

How can I confirm the 16 modules are running at 4800 MT/s with CL40 after installation?

Check the BIOS or UEFI memory information screen; it should report DDR5 4800 speed and CAS latency 40 for all 16 DIMMs.

What is included in the kit and do I need any extra parts?

The kit contains 16 registered ECC RDIMMs of 32 GB each; no additional components are required for a compatible THINKMATE server.

Should I choose the 512 GB 16×32 GB kit or a smaller capacity for my 421GE-TNRT system?

Select the 512 GB kit when the workload needs maximum registered ECC capacity; choose a smaller kit if the application does not require the full 16-module population.
