32GB DDR4 2666MHz ECC UDIMM

This is a single 32GB DDR4 2666MHz PC4-21300 CL19 module built to JEDEC specifications. It runs at 1.2V and uses an unbuffered 288-pin layout with ECC for error correction.

Suited for workstations, servers and NAS systems

Systems that require data integrity benefit from the ECC function and 2RX8 organisation. Platforms without ECC support in the chipset or BIOS should look at non-ECC memory instead.

Steady operation at rated speed

The module maintains 2666MHz under sustained load thanks to standard voltage and JEDEC timings. Backward compatibility with 2133MHz and 2400MHz allows it to downclock automatically when the platform demands it.

Questions about this item

Will this ECC UDIMM work in a standard desktop motherboard?

Only if the motherboard explicitly supports unbuffered ECC memory; many consumer boards do not enable ECC even when the slot fits.

Can I mix this 32GB module with my existing 2133MHz or 2400MHz RAM?

Yes, the module is backward compatible with 2133MHz and 2400MHz speeds and will run at the lowest installed speed.

Does the single 32GB stick leave room for future expansion?

That depends on how many DIMM slots your board has and its maximum supported capacity per slot.
