2TB DDR5 ECC RDIMM kit for Supermicro servers

This kit provides 2TB of DDR5 4800 registered ECC memory across sixteen 128GB modules for Supermicro Storage SuperServer SSG-521E-E1CR24H, SSG-521E-E1CR24L and X13SEDW-F systems. It targets IT professionals who need maximum registered capacity in those specific platforms.

DDR5 4800 registered ECC limits

The DDR5 4800 standard caps this kit at PC5-38400 bandwidth with CL40 latency and 1.1V operation. Registered 4Rx4 organisation and 288-pin form factor mean it only works in motherboards wired for registered DDR5 ECC RDIMMs; consumer boards and unbuffered slots will not accept it.

Straightforward DIMM installation

Modules seat in standard 288-pin DDR5 slots and the kit ships as a matched sixteen-piece set, so no mixing is required. The main risk is ignoring the Supermicro memory population guide — wrong slot order or exceeding the board’s rank limit per channel will prevent boot or reduce usable capacity.

Questions about this item

Should I choose the 16×128 GB kit or a smaller capacity for my Supermicro SSG-521E-E1CR24H?

The kit provides 2 TB total across 16 slots; select it only if your chassis populates all 16 DIMM sockets and the workload needs that density.

What does the DDR5 4800 CL40 rating deliver in a live Supermicro server?

It runs at 4800 MT/s with 40-cycle latency at 1.10 V, giving registered ECC bandwidth of PC5-38400 per module under load.

How does the 288-pin RDIMM interface limit speed or capacity in this platform?

The 288-pin DDR5 RDIMM slot caps at 4800 MT/s and 128 GB per module, so this 4Rx4 kit hits the maximum supported density per socket.
