16GB DDR4 2666MHz ECC RDIMM

This 16GB registered DDR4 module runs at 2666MHz with CL19 latency and operates at 1.20V. It uses a 2Rx8 dual-rank Micron chipset and carries Supermicro certification for server platforms. The 288-pin RDIMM form factor targets systems that require registered ECC memory.

Verify registered ECC support before ordering

Confirm that your motherboard and CPU accept registered ECC DDR4 RDIMMs rather than unbuffered UDIMMs or LRDIMMs. Check the qualified vendor list for 2666MHz CL19 modules and ensure the BIOS can train at PC4-21300 speeds. Mixed-rank populations may have slot restrictions.

Fits single-module upgrades in registered channels

The module slots into a 288-pin DDR4 RDIMM socket and draws standard 1.20V power. It adds 16GB of error-correcting capacity per stick, freeing unbuffered slots for other configurations. Population rules vary by platform, so follow the vendor memory guide for optimal channel balance.

Questions about this item

What comes in the box and do I need anything else to install this module?

The package contains one 16GB DDR4 2666MHz CL19 2Rx8 ECC RDIMM. No extra parts are required; the module plugs directly into a compatible 288-pin registered DIMM slot.

How do I decide between this 16GB module and a different capacity for my server?

Choose this 16GB stick when your board supports registered ECC memory and you need a single dual-rank module to fill an available slot or to match existing 2Rx8 population rules.

What does the 2666MHz rating mean once the module is running in a real system?

The memory will operate at up to 2666 MT/s (PC4-21300) with CL19 latency at the standard 1.20 V, provided the platform enables that speed for registered ECC DIMMs.
