THINKMATE 521C-NR 512GB DDR5 Kit

This 512GB kit contains eight 64GB DDR5 4800 ECC RDIMM modules built for the THINKMATE Supermicro SuperServer 521C-NR. It targets administrators who need maximum registered memory capacity in a single validated package.

288-pin registered DDR5 for server boards

Each module uses a 288-pin DDR5 RDIMM form factor with 2Rx4 organisation and operates at 1.1V. The registered buffer and on-die ECC let the memory controller manage heavy multi-threaded workloads without unbuffered signal limits.

Sustained load stability at CL40

Modules are stress-tested under continuous load at CL40 latency and PC5-38400 data rate. The registered design and ECC correction maintain data integrity during extended compute jobs rather than short benchmarks.

Questions about this item

How many 64 GB modules must the server accept to reach the 512 GB kit capacity?

The kit contains eight 64 GB modules, so the server must support eight DDR5 RDIMM slots to use the full 512 GB.

What is the operating voltage and registered design impact on sustained heat and power draw?

Each module runs at 1.10 V and uses a registered DDR5 design, which reduces electrical load on the memory controller during continuous operation.

Which specific server model is this memory kit validated for?

This DDR5 4800 CL40 ECC RDIMM kit is built for the Thinkmate Supermicro SuperServer 521C-NR.
