16GB DDR4 2666MHz SODIMM Upgrade

This A-Tech module is a 16GB DDR4 2666MHz laptop memory upgrade. It uses a 260-pin SO-DIMM form factor and runs at the standard 1.2V voltage. The kit contains a single unbuffered, non-ECC stick built with major brand chips. It is designed to increase system responsiveness and multitasking capability for compatible notebooks and all-in-one PCs.

Suits HP part numbers listed.

This memory fits systems that accept the HP part numbers 3TK84AA, 3TK84AT, 3TK84TA, 3TQ36AA, 3TQ36AT, 4VN07AA, 4VN07UT and 937438-850. It is intended for standard laptop SO-DIMM slots supporting DDR4 2666 speeds. Buyers whose devices require ECC or registered modules should look elsewhere, as this stick is non-ECC and unbuffered. Always verify your system's supported specifications before purchasing.

Single 16GB module at CL19 latency

The decisive specification is the 16GB capacity delivered in a single module with a CAS latency of CL19. This density allows a full 16GB upgrade in one slot, which is ideal when only one socket is free. Systems needing lower latency or multiple smaller modules for multi-channel bandwidth will not match this configuration.
