Server-grade DDR5 ECC RDIMM kit

This 512GB kit contains eight 64GB DDR5 4800 registered ECC modules built for the Supermicro H13SSL-N motherboard. Each DIMM runs at 1.1V with CL40 latency and a 2Rx4 rank layout that matches the board's memory controller requirements. The registered architecture lets every slot operate fully populated at rated speed. System integrators managing memory-critical workloads will find the spec-aligned design removes guesswork during qualification.

Sustained-load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller so all eight slots remain stable at DDR5 4800 under continuous utilisation. ECC circuitry detects and corrects single-bit errors in real time, preventing silent data corruption during long compute runs. The 2Rx4 organisation and 1.1V operation keep power draw predictable across extended duty cycles. Workloads that cannot tolerate unplanned reboots benefit from this error-handling path.

Build practicality and slot implications

Modules use a standard 288-pin RDIMM form factor without heat spreaders, fitting the H13SSL-N's DIMM sockets directly. The eight-module kit fills the board's supported population sequence in a single order, avoiding mixed-rank configurations that can limit capacity. Buyers needing higher per-module densities or UDIMM/SODIMM form factors should verify their platform supports those alternatives before ordering. Consult the motherboard manual for exact population rules and BIOS settings.

Questions about this item

How much power will the 1.1V DDR5 4800 kit draw when the server runs all day?

Each module operates at 1.10V, the standard DDR5 voltage, so total draw scales with the 512GB capacity and your CPU's memory controller load.

Does the Supermicro H13SSL-N motherboard need a specific BIOS revision or CPU to recognise all 512GB?

The kit is validated for the H13SSL-N; consult the board manual for approved DIMM population order and any BIOS updates required for full 8-slot operation.

Will these 2Rx4 Registered ECC RDIMMs work in the same channels as older RDIMMs I already have installed?

They are 288-pin DDR5 RDIMMs with CL40 timing; mixing ranks or speeds is not recommended and may prevent the system from posting at the rated 4800MHz.
