64GB DDR4 2933MHz ECC RDIMM Server Memory

This 64GB DDR4 module runs at 2933MHz with CL21 latency and 1.20V operation. It is a registered ECC DIMM built with a 2Rx4 organisation for server and workstation platforms. The 288-pin form factor fits standard DDR4 slots in compatible systems.

Registered ECC limits for DDR4 2933MHz

Registered ECC modules add a register between the DRAM and the memory controller, which reduces electrical load and enables larger capacities per channel. The trade-off is one extra clock cycle of latency compared with unbuffered equivalents at the same data rate. Systems must support registered ECC DIMMs; consumer desktop boards typically do not.

64GB single-module capacity decides fit

One 64GB stick delivers high density in a single slot, suited to platforms qualified for 2Rx4 registered DIMMs at this speed. Buyers needing unbuffered memory or non-ECC operation cannot use this module. Verify the system’s qualified vendor list before purchase.
