NEMIX RAM 768GB DDR5 4800 ECC RDIMM Kit

This 768GB kit contains six 128GB DDR5 4800 modules rated at CL40 and 1.1V. The registered ECC RDIMM design targets Supermicro X13SEW-TF and X13SEW-F platforms. It delivers high-density registered memory for enterprise workloads.

Suited for Supermicro DDR5 servers needing maximum

Ideal for administrators populating all slots on compatible Supermicro motherboards with registered ECC memory. Not intended for consumer desktop boards, laptops, or systems that require unbuffered non-ECC modules or lower-density DIMMs.

Registered 4Rx4 organisation at DDR5 4800

Each module uses a 4Rx4 layout with on-die ECC and operates at the standard 4800 MT/s data rate. The registered signal buffering and quad-rank density are the decisive factors for compatibility with the target server platforms.

Questions about this item

Does the 288-pin DDR5 RDIMM form factor fit the SuperMicro X13SEW-TF motherboard slots?

Yes, the 288-pin DDR5 RDIMM modules are designed for the DDR5 slots on the SuperMicro X13SEW-TF and X13SEW-F motherboards.

What is the correct order to populate the six 128GB modules for proper registered ECC operation?

Follow the SuperMicro X13SEW-TF manual to fill the DDR5 channels in the prescribed sequence; registered ECC RDIMMs must occupy the correct slots per channel for the memory controller to initialise.

Will the 4Rx4 rank organisation require a BIOS update on the SuperMicro X13SEW-TF to run at 4800 MT/s?

The 4Rx4 modules operate at DDR5 4800 with CL40 at 1.10 V; check the SuperMicro X13SEW-TF release notes for the minimum BIOS version that supports 128 GB 4Rx4 RDIMMs at that speed.
