Server-grade DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 1TB of DDR5 4800 registered ECC memory across eight 128GB modules. It is built for THINKMATE Supermicro SuperServer 511E-WR and 521E-WR platforms that require 288-pin DDR5 RDIMMs with 4Rx4 organisation and CL40 latency. The modules operate at 1.1V using major OEM DRAM from Samsung, Micron or Hynix.

Registered design for multi-DIMM stability

Registered buffering reduces electrical load on the memory controller, allowing all eight slots to be populated without signal degradation. ECC corrects single-bit errors to protect data integrity in mission-critical workloads. The kit requires a motherboard with DDR5 RDIMM slots and a CPU memory controller that supports 4800 MT/s registered modules at 1.1V.

Suited for high-capacity server upgrades

This kit suits administrators expanding 511E-WR or 521E-WR servers to the maximum supported DIMM count. It is not for desktop boards that accept only unbuffered UDIMMs, nor for systems limited to lower densities or slower DDR5 speeds. Buyers needing non-ECC memory or consumer form factors should look elsewhere.

Questions about this item

Does the 1.1 V operating voltage limit headroom when the eight 128 GB modules run continuously at 4800 MT/s?

The kit is specified at 1.10 V for DDR5 4800 operation; sustained loads at that speed stay within the rated voltage without additional headroom.

How much heat do the eight registered 4Rx4 modules generate during all-day workloads without a heat spreader?

Eight 128 GB RDIMMs at 1.1 V produce measurable heat under continuous load; ensure the server chassis provides adequate airflow across the bare modules.

Which Thinkmate Supermicro SuperServer models must the buyer already own for this 288-pin kit to function?

This memory kit is validated for the Thinkmate Supermicro SuperServer 511E-WR and 521E-WR platforms.
