Exact-match DDR5-4800 ECC RDIMM kit

This 64 GB kit contains two 32 GB registered DDR5 modules rated at 4800 MT/s with CL40 latency and 1.1 V operation. The 2Rx8 organisation and ECC function match the Supermicro H13DSG-O-CPU-D memory controller so the system recognises full capacity at rated speed.

Suited for servers needing registered ECC memory

Administrators populating every slot on the H13DSG-O-CPU-D board gain full-capacity stability with registered buffering and on-the-fly error correction. Builders requiring unbuffered UDIMMs, SODIMM form factors or non-ECC modules should look at something else.

Straightforward 288-pin RDIMM installation

Align the key notch, press firmly until the ejectors click, and follow the motherboard manual for approved population order. The most common issue is mixing ranks or skipping the prescribed slot sequence, which prevents the system from posting.

Questions about this item

Do I need a Supermicro H13DSG-O-CPU-D motherboard with DDR5 RDIMM slots to use this 64GB kit?

Yes, this 2x32GB DDR5 4800 CL40 1.1V 2Rx8 ECC RDIMM kit is built for the Supermicro H13DSG-O-CPU-D and requires its 288-pin registered DIMM slots.

Can I add these 32GB DDR5 4800 RDIMMs to existing DDR5 RDIMMs of a different capacity or speed in the same server?

Mixing capacities or speeds is possible only if the motherboard manual approves the specific population order; otherwise the system may downclock or fail to boot.

How do I confirm the kit runs at DDR5 4800 CL40 with ECC active after installation?

Check the BIOS memory information or OS tools such as dmidecode to verify 4800 MT/s, CL40 timings, 1.1V operation and ECC registered status on both 32GB modules.
