  • Major OEM Samsung, Micron, Hynix chips ensure enterprise-grade component quality

Exact-match DDR5 server kit

This 1TB kit contains eight 128GB DDR5 registered ECC RDIMMs built to the exact rank, voltage, and timing the Supermicro H13SSL-N motherboard expects. The modules install in the 288-pin slots and are recognised at full capacity without manual configuration. Buyers who need unbuffered UDIMMs or SODIMM form factors cannot use this kit.

Sustained-load stability

Registered buffering offloads the memory controller so every slot runs fully populated at the rated 4800 speed, while ECC corrects single-bit errors on the fly to prevent silent data corruption. The 1.1V operating voltage keeps power draw predictable during continuous workloads. Systems that require higher frequencies or lower latencies than CL40 will not reach those targets with this memory.

Installation and common issues

The 288-pin RDIMMs seat in the board's DDR5 slots following the population order shown in the motherboard manual. Missing a required BIOS update or populating slots in the wrong sequence are the usual reasons the full 1TB is not detected. Builders without access to the system documentation should verify the supported configuration before opening the package.

Questions about this item

How much heat and power does the 1TB DDR5 kit draw when all eight 128GB modules run continuously?

Each module operates at 1.1V with DDR5 4800 speed and CL40 timing; the registered design reduces electrical load on the memory controller, helping keep power draw and heat predictable across all eight slots.

What motherboard and memory-controller features must my system already have for this 288-pin RDIMM kit to function?

The Supermicro H13SSL-N motherboard with DDR5 registered DIMM slots and ECC support is required; the board must accept 2Rx4 128GB modules at 4800MHz and 1.1V.

Will the 2Rx4 registered ECC modules work alongside any existing DDR5 RDIMMs I keep in the H13SSL-N?

Mixing ranks or capacities can change the memory-controller population rules; consult the H13SSL-N manual for approved DIMM order before adding this 8x128GB kit to installed modules.
