Server memory kit for Thinkmate Supermicro systems

This 1.5TB kit contains twelve 128GB DDR5 RDIMMs built for Thinkmate Supermicro SuperServer 611C-TN4R and 621C-TN12R platforms. It targets administrators who need maximum registered ECC capacity in validated configurations. The modules arrive new and ready for installation in supported 288-pin slots.

Registered ECC DDR5 4800 with 4Rx4 organisation

Each module runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.10V and uses a 4Rx4 layout. The registered buffer and on-die ECC protect data integrity in multi-socket workloads. Samsung, Micron or Hynix major-OEM DRAM ensures consistent supply and qualification.

1.5TB total capacity across twelve slots

The kit fills twelve DIMM sockets with 128GB each, delivering 1.5TB of addressable memory for large databases, virtualisation clusters or HPC jobs. Headroom ends when all supported slots are populated; further expansion requires a platform with additional channels or higher-density modules.

Questions about this item

What does the 4800 MT/s rating deliver once the modules are installed in a ThinkMate Supermicro server?

The kit runs at DDR5-4800 (PC5-38400), so each 128 GB module transfers data at 4800 MT/s with CL40 latency, giving the full 1.5 TB capacity at the rated speed when the platform supports it.

How does the registered ECC RDIMM design affect compatibility and bandwidth limits?

Registered ECC RDIMMs add a register that buffers commands, allowing the 4Rx4 organisation across 12 modules to operate reliably on the supported ThinkMate Supermicro 611C-TN4R and 621C-TN12R platforms.

What physical slot and power requirements must the server meet for this 12-module kit?

Each module is a 288-pin DDR5 RDIMM operating at 1.10 V; the server must provide 12 DDR5 RDIMM slots and supply 1.10 V to the memory bus.
