64GB DDR4 2666 ECC RDIMM for Supermicro servers

This 64GB registered DDR4 module runs at 2666MHz with CL19 latency and 1.20V operation. It uses a 4Rx4 organisation and 288-pin form factor for Supermicro server and workstation platforms. ECC and registered buffering provide the data integrity required in mission-critical environments.

Sustained load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC corrects single-bit errors on the fly, preventing data corruption during long compute runs. The 4Rx4 density delivers high capacity per slot while maintaining stability under constant throughput demands.

Verify Supermicro model and slot population rules

Confirm the target system appears in the Supermicro MEM-DR464L-SL01-ER26 compatibility list before ordering. Check the motherboard manual for maximum supported capacity per channel and approved rank configurations. Ensure the BIOS revision supports 4Rx4 registered modules at the rated speed.

Preguntas sobre este artículo

How much power does the 1.2 V DDR4 2666 module draw when the server runs continuously?

The module operates at 1.20 V, the standard voltage for DDR4 RDIMMs, so power draw stays within the normal range for registered server memory under sustained load.

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

The board must support DDR4 registered ECC memory with 4Rx4 organisation and a 288-pin RDIMM slot; Supermicro platforms listed in the compatibility data meet that requirement.

Will the CL19 2666 MT/s timing slow down existing DDR4 2666 RDIMMs already installed in the same Supermicro server?

All modules run at the lowest common speed and latency, so adding this CL19 stick will not force faster modules to run slower than 2666 MT/s CL19.
