4GB DDR4 SODIMM for HP 15-Ay0Xxtx

This 4 GB DDR4 2133 MHz SODIMM module is built for HP and Compaq 15-Ay0Xxtx notebooks. It delivers a straightforward capacity boost for everyday multitasking and office workloads on those specific platforms.

Check your notebook has a free 260-pin slot

Verify the machine uses a single SO-DIMM slot and accepts 2133 MHz PC4-17000 memory. The system maximum is 12 GB, so adding this stick will not exceed the platform limit if the slot is vacant.

Sustained CL15 timing at 1.2 V without a heat

Under continuous load the unbuffered 1Rx8 chips maintain CL15 15-15-15 latency at standard voltage. The absence of a spreader means thermals depend on the notebook’s internal airflow rather than dedicated cooling.

Questions about this item

What comes in the package and is anything else required for installation?

The box contains one 4 GB DDR4 2133 MHz SODIMM module; no extra parts or tools are needed to install it in a compatible notebook.

Should I choose this 4 GB stick or look for a larger capacity for my HP 15-ay0xxtx?

The notebook supports a maximum of 12 GB and has a single memory slot, so a single 4 GB module is a direct upgrade; larger single sticks can be used if they match the DDR4 2133 SODIMM specification.

What does the 2133 MHz rating mean once the module is running in the laptop?

The memory will operate at 2133 MT/s with CL15 timings at 1.2 V, delivering the standard DDR4 2133 bandwidth supported by the HP 15-ay0xxtx platform.
