Exact DDR5-4800 ECC RDIMM kit for Supermicro H13DSH

This 128GB kit contains four 32GB Registered DDR5 modules rated at 4800 MT/s, CL40, 1.10V, 2Rx8 organisation. It is built for servers that require ECC error correction and registered buffering to run every slot fully populated at rated speed. The 288-pin form factor matches the board's memory slots precisely.

Verify motherboard population rules before ordering

Check the Supermicro H13DSH manual for supported capacities per channel, approved DIMM installation order, and any BIOS version requirements. Confirm the board accepts 2Rx8 Registered DDR5 at 1.10V and that all four slots can be filled simultaneously. Ensure the system does not require UDIMM, SODIMM or non-ECC modules instead.

Suits administrators upgrading a validated H13DSH

This kit fits IT teams needing a matched 128GB upgrade that the motherboard recognises at full capacity without manual tuning. It is not for builds that need unbuffered memory, consumer desktop boards, or systems limited to lower densities per slot. Buyers who want different capacities or speeds should consult the board's qualified-vendor list.

Questions about this item

Does the 128GB 4x32GB DDR5 4800 kit include anything besides the four registered ECC RDIMMs?

The package contains only the four 32GB DDR5 4800 CL40 1.1V 2Rx8 288-pin ECC registered RDIMMs; no heat spreaders, cables, tools or documentation are included.

Why choose the 128GB 4x32GB CL40 kit instead of a smaller capacity or different latency for the Supermicro H13DSH?

This exact-match kit provides the 2Rx8 registered ECC configuration and 1.1V voltage the H13DSH memory controller expects, allowing full 128GB capacity at the rated DDR5 4800 speed.

What does the DDR5 4800 PC5-38400 rating mean once the modules are installed in the H13DSH?

The modules will operate at 4800 MT/s with CL40 timing at 1.1V, delivering the standard PC5-38400 bandwidth the motherboard's memory controller is designed for.
