Compatible upgrade for HP Pavilion notebooks

This 8 GB DDR4 SO-DIMM is built for HP Pavilion Gaming 15-dk0xxx, 15t-dk0xxx and Pavilion 15-cs3xxx models. It uses a 260-pin layout and runs at 1.2 V without ECC or buffering. The module adds memory to systems that support up to 32 GB across two slots.

Steady throughput at 2666 MHz

Rated at 2666 MHz with PC4-21300 bandwidth, the stick operates at CL19 timings of 19-19-19. As an unbuffered 1Rx8 design it maintains consistent latency during extended workloads rather than only in short bursts. All installed memory will run at the speed of the slowest module or the processor limit.

Simple slot installation

The SO-DIMM inserts directly into the notebook's memory slot with no heat spreader to clear. Mixing brands is possible but forces every module to the lowest common speed. A 64-bit operating system is required to address more than 4 GB, and the system maximum is 32 GB over two sockets.

Questions about this item

How much power does the 1.2 V DDR4 module draw under sustained load?

The module operates at the standard DDR4 voltage of 1.2 V; power draw scales with frequency and system workload rather than a fixed peak figure.

Does the HP Pavilion notebook need a 64-bit OS to recognise the full 8 GB?

Yes, the supplier notes that a 64-bit operating system is required to utilise more than 4 GB of memory.

Will the CL19 stick downclock to match the slowest module already installed?

All memory in the system runs at the speed of the slowest installed module or the processor’s maximum supported rate.
