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.
