Micron 32GB DDR4 2666 ECC Unbuffered DIMM

This 288-pin DDR4 module delivers 32 GB of dual-rank server memory with ECC protection. It operates at 2666 MT/s (PC4 21300) and runs unbuffered for direct CPU attachment. The stick is suited to entry-level servers and workstations that require error-correcting RAM without registered signalling. Condition is new and sourced directly from Micron.

Fits unbuffered ECC platforms.

This module suits administrators upgrading or populating servers that accept unbuffered ECC DDR4. Builders whose motherboards demand registered RDIMMs or standard desktop UDIMMs without ECC will not be able to use this part. Buyers needing higher capacities or faster speeds must select different modules.

Dual-rank 32 GB capacity decides fit

The single specification that determines compatibility is the 32 GB dual-rank density at DDR4 2666. Systems limited to single-rank DIMMs or lower maximum module sizes will reject this stick. Verify the platform’s qualified-vendor list for this exact rank and capacity before purchasing.

Questions about this item

What speed does DDR4 2666 (PC4 21300) run at in practice?

The modules operate at 2666 MT/s with a peak transfer rate of PC4 21300.

Does the 288-pin DDR4 form factor fit my server board?

It uses the standard 288-pin DDR4 layout, so it fits any slot that accepts unbuffered DDR4 DIMMs.

How do I install dual-rank ECC unbuffered DIMMs correctly?

Align the notch, press firmly until the retention clips click, and populate channels per the motherboard manual to enable ECC.
