2GB DDR4-2666 ECC Registered DIMM

This 2GB DDR4-2666 module is built for servers and workstations that require error-correcting registered memory. It fits 288-pin DDR4 slots and runs at PC4-21300 speed for stable operation in multi-DIMM configurations.

Capacity and ECC registration

The single specification that decides fit is the 2GB capacity combined with ECC registered operation; systems needing unbuffered non-ECC DDR4 or larger individual modules cannot use this part.

商品問答

What does the 2666 speed mean for real-world server performance?

The DDR4 2666 rating indicates a data rate of 2666 MT/s, which determines how quickly this registered ECC module can feed data to the CPU in a compatible system.

How does the PC4 21300 designation limit this module in practice?

PC4 21300 is the peak bandwidth specification for DDR4 2666, capping the maximum theoretical throughput this DIMM can deliver on a supported platform.
