512GB DDR5 4800 ECC RDIMM kit

This 512GB kit contains eight 64GB DDR5 4800 registered ECC modules built for THINKMATE Supermicro SuperServer 621P-TR, 621P-TRT and 221P-C9R platforms. Each module runs at 1.10V with CL40 latency and a 2Rx4 organisation. The registered design adds a buffer that helps maintain signal integrity across all populated slots. It targets administrators who need maximum supported capacity in these specific servers.

Sustained load behaviour

Registered ECC modules correct single-bit errors on the fly and the register reduces electrical loading on the memory controller when every slot is filled. At DDR5 4800 the kit delivers PC5-38400 bandwidth continuously across all eight DIMMs. The 1.10V operating voltage keeps power draw predictable during long compute runs. No heat spreaders are fitted, so chassis airflow must handle the thermal load.

Upgrade context

The kit replaces any smaller-capacity DDR5 RDIMM set in the listed SuperServer models to reach the full 512GB configuration. The jump is worth it when workloads such as virtualisation, in-memory databases or large dataset processing exceed the current memory ceiling. Compatibility is validated for the 621P-TR, 621P-TRT and 221P-C9R part numbers only.

商品問答

Will the 1.10 V DDR5 modules add much heat or power draw when the ThinkMate 621P-TR runs continuously?

Each module operates at 1.10 V, the standard DDR5 voltage, so power draw per DIMM is low; total system heat will depend on the server's cooling design and the eight modules installed.

What must the ThinkMate 621P-TR already have to accept this 512 GB kit?

The server needs eight free 288-pin DDR5 RDIMM slots and a BIOS that supports 64 GB 2Rx4 registered ECC modules at 4800 MT/s.

Can the CL40 2Rx4 modules work alongside any existing DDR5 RDIMMs in a ThinkMate 621P-TR?

Mixing is possible only if the other modules are also DDR5 4800 registered ECC 2Rx4 at 1.10 V; otherwise the system will default to the slowest common speed or may not post.
