Six green DDR5 RDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM 384GB (6x64GB) DDR5 4800 CL40 ECC RDIMM SuperMicro Server memory upgrade

SKU CH-16MT-926NS

Six-module 384GB DDR5 ECC RDIMM kit at 4800MT/s CL40 for SuperMicro servers

  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • 384 GB total capacity from six 64 GB modules
  • DDR5 4800 speed with CL40 latency for responsive server workloads
  • ECC registered RDIMM design protects data integrity under heavy load
  • 1 V operation reduces power draw in dense configurations
  • Validated for Supermicro SSG-521E and X13SEDW-F platforms

Targeted SuperMicro Server Upgrade

This 384GB kit delivers six 64GB DDR5 4800 registered ECC RDIMMs built for SuperMicro Storage SuperServer models including the SSG-521E-E1CR24H, SSG-521E-E1CR24L and X13SEDW-F. It is designed for administrators who need maximum memory capacity in compatible 13th generation platforms.

Registered ECC Build for 24/7 Operation

Each module uses 2Rx4 organisation at 1.10V with CL40 latency and no heat spreader, relying on server chassis airflow for cooling. The 288-pin RDIMM form factor locks into registered DIMM slots, providing the signal integrity required for sustained workloads in multi-socket configurations.

Replaces Smaller RDIMM Sets or Mixed Kits

The jump is worth it when a SuperMicro SSG-521E or X13SEDW-F system is capped at a lower total capacity or runs mismatched modules that limit stability. This kit populates six slots with identical 64GB sticks, eliminating rank-mismatch issues and delivering the full 384GB the platform supports.

Highlights

  • 384 GB total capacity from six 64 GB modules
  • DDR5 4800 speed with CL40 latency for responsive server workloads
  • ECC registered RDIMM design protects data integrity under heavy load
  • 1 V operation reduces power draw in dense configurations
  • Validated for Supermicro SSG-521E and X13SEDW-F platforms

Questions about this item

Does the DDR5 4800 PC5-38400 interface cap the modules at 4800 MT/s?

Yes, the kit is rated for DDR5 4800 which corresponds to PC5-38400, so the maximum data rate is 4800 MT/s.

What physical slot and pin count do these 64 GB RDIMMs require?

Each module is a 288-pin DDR5 RDIMM, so the motherboard must provide 288-pin DDR5 RDIMM slots.

How are the six modules installed, and what step is often missed?

Populate the six 64 GB modules in the channel order specified by the SuperMicro manual and ensure each RDIMM clicks fully into its 288-pin slot; the step often missed is verifying the correct population sequence for 2Rx4 registered DIMMs.
