16GB DDR4-2666 ECC RDIMM for servers

This Micron registered DIMM delivers 16GB of DDR4 memory at 2666 MT/s with ECC protection. It uses the standard 288-pin form factor and is built for server platforms that require registered, error-correcting modules.

ECC and registered design maintain data integrity

The on-board error-correcting code detects and corrects single-bit errors, while the register buffers address and command signals to reduce electrical load on the memory controller. Systems that require unbuffered non-ECC memory cannot use this module.

Questions about this item

Will the ECC RDIMM modules need any firmware updates or component replacements during their service life?

No firmware updates or component replacements are required; the ECC RDIMM operates without user-serviceable parts.

What thermal limit appears first when the DDR4-2666 modules run at full load continuously?

The DDR4-2666 RDIMM is rated for standard JEDEC operating temperatures; sustained full load stays within that envelope.
