1TB DDR5 ECC Registered Kit

This kit provides one terabyte of DDR5 memory across eight 128GB registered DIMMs. It is built for SuperMicro X13SEW-TF and X13SEW-F motherboards that require registered ECC modules. The kit targets server and workstation administrators expanding memory capacity for virtualisation or database workloads.

Suited for compatible SuperMicro servers.

The modules suit IT teams deploying SuperMicro X13SEW platforms that mandate registered ECC memory. Builders using consumer desktop boards, laptops or any system requiring unbuffered non-ECC DIMMs cannot use this kit. Workstations needing lower-capacity sticks or different form factors should look elsewhere.

DDR5 4800 CL40 288-pin RDIMM spec

The memory runs at DDR5 4800 with a CAS latency of 40 and operates at 1.1V. Each module uses a 4Rx4 organisation on a 288-pin registered DIMM. This specification decides whether the kit matches the motherboard qualified-vendor list.

Questions about this item

My SuperMicro X13SEW-TF board has 13 DDR5 slots — do I need to fill all of them for this 1TB kit to run correctly?

The kit contains eight 128GB modules. Populate the eight slots your CPU and manual specify; the board does not require all 13 slots to be filled for the memory to operate.

Can I keep my existing DDR5 4800 CL40 registered ECC DIMMs and add this 4Rx4 kit without timing conflicts?

All modules must share the same 4800 MT/s speed, 1.10 V voltage and CL40 latency. Mixing different rank architectures such as 4Rx4 with other ranks can prevent the system from training at the rated speed.

After installation, how do I confirm the full 1TB is recognised at DDR5 4800 with ECC active?

Enter the BIOS or run a hardware inventory tool such as dmidecode; it should show eight 128GB RDIMMs at 4800 MT/s, 1.10 V, CL40, with ECC and registered status reported for each module.
