384GB DDR5 4800 ECC RDIMM Kit

This NEMIX RAM kit delivers 384GB of registered DDR5 memory across four 96GB modules. Each module operates at 4800 MT/s with a CL40 latency and a 1.10V supply. The 2Rx4 organisation and on-die ECC suit enterprise workloads that demand data integrity and high capacity per slot.

Suited to multi-socket servers

The registered signal and ECC function are required by most server chipsets, so consumer motherboards cannot use these modules. Builders who need unbuffered DIMMs or lower-density sticks for a workstation board should look at a different product line.

Sustained load behaviour with registered DDR5

The on-board register absorbs electrical loading on the command bus, keeping signal quality stable during long compile jobs or database scans. ECC corrects single-bit errors in real time, preventing silent data corruption when the kit runs at full 384GB capacity for hours.

Questions about this item

What type of motherboard slots are required for these 288-pin DDR5 RDIMM modules?

You need a server or workstation motherboard with DDR5 RDIMM slots that support registered ECC memory and a 1.10V operating voltage.

Can I mix these CL40 4800 MT/s modules with slower DDR5 ECC RDIMMs already in my system?

The system will run all installed modules at the speed and timings of the slowest kit, so mixing is possible but total bandwidth will drop to the lower spec.

How can I verify the full 384GB capacity is recognised and ECC is active after installation?

Check the BIOS memory information screen or run a tool like dmidecode to confirm four 96GB modules at 4800 MT/s with ECC enabled.
