16GB DDR4 2666MHz ECC SODIMM

This 16GB DDR4 2666MHz ECC SODIMM module adds 16GB of error-correcting memory to compatible laptops and mobile workstations. It runs at 2666MHz with CL19 latency and 1.20V, using unbuffered 2Rx8 architecture and major-brand chips. The 260-pin form factor fits standard DDR4 SO-DIMM slots in supported systems.

Who this suits and who should look elsewhere

This module suits owners of HP part numbers 3TQ38AA, 3TQ38AT or 4UY12AA who need ECC unbuffered SO-DIMM memory for server or workstation workloads. Buyers whose systems require registered or buffered ECC modules, non-ECC memory, or a different speed or voltage should look elsewhere.

The spec that decides fit

The deciding specification is ECC unbuffered SO-DIMM at DDR4 2666MHz with CL19 timing and 1.20V. Only systems that explicitly support ECC unbuffered DDR4 SO-DIMMs at this speed and voltage will operate correctly with this module.

Questions about this item

Does this 260-pin DDR4 SODIMM fit a standard laptop memory slot?

Yes, the 260-pin DDR4 SO-DIMM form factor matches the standard slot used in compatible laptops and workstations.

What is the correct way to seat this ECC unbuffered module during installation?

Align the notch with the slot key, insert at an angle, then press down firmly until both side clips click into place.

Will the ECC error-correction feature require any special configuration or replacement over time?

ECC operates automatically once the system BIOS supports it; no ongoing maintenance or replacement is needed for the memory itself.
