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.

商品問答

Should I choose the 64GB 2Rx4 module or a different capacity for my server?

This module provides 64GB in a single 2Rx4 DDR4 2933MHz ECC RDIMM. Choose it when your system needs maximum capacity per slot and supports registered ECC memory.

What does the DDR4 2933MHz PC4-23400 rating mean for actual server performance?

The module runs at 2933 MT/s with CL21 latency at 1.20V, delivering the rated PC4-23400 data rate for compatible server and workstation platforms.

How does the 288-pin DDR4 RDIMM interface limit speed and capacity in practice?

The 288-pin registered DIMM form factor supports DDR4 2933MHz operation with ECC error correction, enabling 64GB density per module on qualified server motherboards.
