  • ECC registered design protects data integrity in servers
  • 1 V operation reduces power draw under load
  • Qualified for ThinkMate Supermicro SuperServer 421GE-TNRT platforms

Capacity and Compatibility

This 512GB kit contains four 128GB DDR5 RDIMM modules validated for THINKMATE Supermicro SuperServer 421GE-TNRT and 421GE-TNRT3 systems. It targets administrators who need maximum registered ECC capacity in those specific platforms.

Installation Notes

The 288-pin DDR5 RDIMM form factor fits the designated server DIMM slots and operates at 1.1V with CL40 latency. Registered 4Rx4 modules require the motherboard memory controller to support quad-rank registered DIMMs; verify the server BIOS revision and population rules before installing to avoid POST failures.

Suitability

This kit suits IT teams expanding memory in the listed SuperServer models where 4Rx4 registered ECC DDR5 is qualified. Buyers needing unbuffered UDIMM modules, lower capacities, different speeds, or compatibility with other server brands should look elsewhere.
