Server memory kit for Supermicro DDR5 systems

This kit supplies 512 GB across four 128 GB registered DIMMs built for Supermicro IOT SuperServer platforms. It runs at DDR5 4800 with CL40 latency and 1.1 V operation. ECC and 4Rx4 organisation protect data integrity in mission-critical workloads.

Suited for administrators expanding Supermicro

Builders who need registered ECC memory for these specific Supermicro models will find a validated match. Systems that require unbuffered DIMMs, lower capacities or a different DDR generation cannot use this kit.

Installs in 288-pin DDR5 RDIMM slots on supported

The modules draw 1.1 V and present a 4Rx4 load to the memory controller. No heat spreaders are fitted, so chassis airflow must handle thermal management. The four-DIMM population fills four slots and leaves remaining channels free for further expansion.

Questions about this item

Does this kit require a motherboard with 288-pin DDR5 RDIMM slots?

Yes, each module uses the 288-pin DDR5 RDIMM form factor and must be installed in matching registered DIMM slots.

Can I mix these 4Rx4 CL40 modules with existing 2Rx8 DDR5 RDIMMs?

Mixing different rank architectures is not recommended; the server memory controller expects uniform rank configuration per channel for stable operation.

How do I verify the kit runs at 4800 MT/s with CL40 after installation?

Check the BIOS memory information or use a tool such as dmidecode to confirm speed 4800, CAS latency 40 and 1.1 V operation.
