System-Specific Server Memory Kit

This 256GB kit contains sixteen 16GB DDR5 4800 RDIMM modules built for the ThinkMate Supermicro SuperServer 681E-TR. Registered ECC design targets administrators who need maximum capacity with error correction in a validated configuration.

Capacity and Headroom

Sixteen ranks of 1Rx8 chips deliver 256GB at PC5-38400 speed with CL40 latency. The registered buffer helps the memory controller manage heavy multi-threaded workloads, while ECC corrects single-bit errors that would otherwise crash long-running jobs.

Thermals and Power Draw

Modules operate at 1.10V without heat spreaders, relying on chassis airflow for cooling. Lower voltage reduces power draw per DIMM compared to previous DDR generations, keeping thermal load predictable inside dense 1U or 2U server enclosures.
