1TB DDR5-4800 RDIMM kit for Supermicro H13DSG-O-CPU

This 16-module kit provides 1TB of DDR5 4800 registered ECC memory. Each module is a 64GB 2Rx4 RDIMM operating at 1.1V with CL40 timing. The 288-pin form factor matches the motherboard's memory slots exactly. It is built for servers that require full-capacity population with error correction.

Who this suits and who should look elsewhere

Suits administrators upgrading a Supermicro H13DSG-O-CPU system to its maximum supported capacity with validated registered ECC modules. Not for builds using consumer UDIMM or SODIMM slots, nor for platforms that cannot accept 2Rx4 registered DIMMs or require different voltages or timings.

The specification that decides fit

Registered (RDIMM) 2Rx4 architecture at DDR5 4800 with 1.1V CL40 timing. The motherboard must support 288-pin registered ECC modules in a 16-slot configuration to recognise the full 1TB. Verify the memory population rules in the system manual before purchase.

Questions about this item

What speed does the DDR5 4800 kit run at on the Supermicro H13DSG-O-CPU?

The kit is rated for DDR5 4800 MT/s and will run at that speed when the motherboard populates all 16 slots according to its population rules.

What physical slot and form factor do these 64 GB modules need?

They are 288-pin RDIMMs, so they only fit the server's 288-pin DDR5 RDIMM slots; UDIMM or SODIMM slots will not accept them.

What is the correct installation sequence for all 16 modules on this board?

Follow the Supermicro H13DSG-O-CPU manual for the exact DIMM population order; skipping the prescribed sequence is the most common mistake that prevents full 1 TB recognition.
