SuperMicro DDR5 64GB ECC RDIMM

This 64GB DDR5 module is built for SuperMicro server and workstation platforms that require registered ECC memory. It operates at 4800MHz with a CL46 latency and runs at the standard 1.1V. The 2Rx4 organisation and 288-pin RDIMM form factor suit multi-socket boards that need high-density registered DIMMs.

Sustained load stability with registered ECC

Registered buffering reduces electrical load on the memory controller, helping the module maintain signal integrity during long-running workloads. On-die ECC corrects single-bit errors without halting the system, while the 1.1V operation keeps power draw predictable across extended compute tasks. Major OEM Samsung, Micron or Hynix DRAM chips are stress-tested under load before shipping.

Verify registered DDR5 support and slot population

Confirm the target SuperMicro system accepts 288-pin DDR5 RDIMMs and supports 2Rx4 modules at 4800MHz. Check the motherboard manual for maximum per-slot capacity and the required population order for registered memory. Ensure the BIOS is current enough to initialise DDR5 registered DIMMs at the rated speed and voltage.

Questions about this item

How much heat does the 1.1V DDR5 4800 module generate during continuous server workloads?

At 1.1V the module draws minimal power for DDR5, so sustained heat output stays low inside a properly ventilated Supermicro chassis.

What motherboard feature must my Supermicro system provide for this 288-pin ECC RDIMM to function?

The board must support DDR5 registered DIMM slots with ECC enabled; consumer DDR5 slots that lack register and ECC support will not work.

Will this CL46 2Rx4 stick run stably alongside existing CL40 DDR5 modules in the same server?

The system will clock all modules to the slowest common timing, so mixing CL46 with CL40 parts works but forces the faster sticks to run at CL46 latency.
