Exact-match upgrade kit

This 256GB kit contains 16 DDR5 RDIMMs, each 16GB, built for the Supermicro H13DSG-O-CPU motherboard. The modules run at 4800MHz with CL40 latency and 1.10V voltage. Registered ECC architecture ensures the memory controller recognises full capacity across every populated slot.

Thermals noise and power

Registered buffering reduces electrical load on the memory controller so all 16 slots operate at rated speed without extra strain. The 1.10V operating voltage keeps power draw low for a fully populated server. No heat spreaders are fitted, relying on chassis airflow for cooling.

Build quality and daily implications

Major-brand Samsung, Micron or Hynix chips provide enterprise-grade stability and on-the-fly single-bit error correction. The 288-pin RDIMM form factor matches the board's required population rules exactly. Verify your manual for approved DIMM order before installation.

Questions about this item

How do I install the 16x16GB DDR5 4800MHz CL40 RDIMM kit in the Supermicro H13DSG-O-CPU and what population step is often missed?

Populate all 16 slots following the motherboard manual's exact DIMM sequence; the step most often missed is using the prescribed population order instead of filling slots sequentially from CPU 0.

What maintenance or replacement will the 256GB 1Rx8 ECC Registered DDR5 kit need later?

No routine maintenance is required; if a module fails the lifetime replacement warranty covers it, otherwise the kit runs until a capacity or speed upgrade is desired.

What limit appears first on the 288-pin 1.1V RDIMM kit under sustained full-load use?

The memory controller's thermal and signal-integrity ceiling at DDR5-4800 CL40 1Rx8 across all 16 ranks is the first sustained-use limit.
