NEMIX RAM 256GB (8×32GB) DDR5 4800 CL40 ECC RDIMM memory upgrade

Server-grade capacity

This 256GB kit provides eight 32GB DDR5 4800 registered DIMMs with ECC and CL40 latency. It targets administrators expanding memory in Thinkmate Supermicro SuperServer 621P-TR, 621P-TRT and 221P-C9R platforms that require registered error-correcting modules. The 1.10V operating voltage matches the DDR5 baseline for these qualified systems.

Registered DIMM integration

Each 288-pin RDIMM presents a 1Rx4 organisation that the memory controller addresses as a single rank per module. The registered buffer reduces electrical load on the server’s memory bus, allowing all eight slots to be populated without additional buffering hardware. ECC circuitry corrects single-bit errors and detects multi-bit faults to protect data integrity in mission-critical workloads.

Sustained-load stability

Modules are stress-tested under continuous load before shipment to verify reliable operation at the rated 4800 MT/s transfer rate. The absence of a heat spreader means airflow through the server chassis must meet the platform’s thermal design for the memory subsystem. Builders needing non-registered UDIMMs or capacities beyond 256GB should select a different kit.
