System-specific DDR5 ECC RDIMM kit for Thinkmate

This 1 TB kit contains sixteen 64 GB registered DDR5 modules built for the Thinkmate Supermicro SuperServer 681E-TR. Each module runs at DDR5 4800 with CL40 latency and 1.10 V operation. The ECC registered design targets administrators who need maximum capacity and error correction in a validated server platform.

Sustained-load behaviour with registered ECC DDR5

Registered buffering and on-die ECC keep data integrity intact during continuous multi-threaded workloads such as virtualization, database hosting or scientific compute. The 2Rx4 organisation spreads accesses across ranks, helping maintain throughput when all sixteen slots are populated. Modules are stress-tested under load before shipping to reduce early-life failures in 24/7 environments.

Build and connector details for daily operation

Modules use the standard 288-pin DDR5 RDIMM form factor without heat spreaders, relying on server chassis airflow for cooling. Major OEM DRAM from Samsung, Micron or Hynix underpins the build. The kit arrives as a matched 16-piece set (part number MR38400-924K16) so installation follows the motherboard population guide without mixing ranks or speeds.

Questions about this item

How much power does the full 1 TB kit draw at the rated 1.1 V?

Each module runs at 1.1 V; the kit contains 16 modules, so total power scales with the number of populated slots in the Thinkmate 681E-TR chassis.

Does the Thinkmate 681E-TR motherboard need a specific BIOS revision or CPU generation to recognise these 4800 MT/s CL40 RDIMMs?

The kit is validated for the Thinkmate 681E-TR platform; install the modules in the supported DDR5 RDIMM slots following the system manual.

Can I keep existing DDR5 4800 RDIMMs in the same server and add this 16 x 64 GB kit?

All modules are 288-pin DDR5 ECC registered RDIMMs at 4800 MT/s CL40, so they share the same electrical and timing profile for mixed population.
