HP Envy x360 15-aq DDR4 SODIMM

This 4GB DDR4 SODIMM is built for the HP Envy x360 15-aq series including models 15-aq000nb, 15-aq000ng, 15-aq000nn, 15-aq000nr and 15-aq001na. It targets owners of those specific convertibles who need a straightforward capacity increase. The module is not for users whose laptops require a different pin count, voltage or DDR generation.

260-pin unbuffered non-ECC module

The stick uses a standard 260-pin SO-DIMM edge connector with no heat spreader, so it fits the slim SODIMM slot found in the compatible Envy models. Operation at 1.2V matches the platform's low-voltage requirement and keeps power draw minimal. Installation is a typical DIY step once the bottom cover is removed. Buyers whose devices use soldered memory or a different form factor cannot use this module.

DDR4 2133 CL15 JEDEC standard

The memory runs at 2133MHz (PC4-17000) with CL15 latency under JEDEC specifications, delivering the baseline speed the chipset expects. It will not exceed that frequency even if the system supports faster modules, and it cannot operate at lower voltages than 1.2V. Systems limited to lower maximum capacities or different timing tables will not benefit from this upgrade.

Questions about this item

Does the DDR4 2133MHz PC4-17000 interface cap the bandwidth at 17000 MB/s in practice?

Yes, the DDR4 2133MHz PC4-17000 rating means the module is specified for a peak transfer rate of 17000 MB/s, and real-world throughput will not exceed that figure.

What physical slot and form factor does this 260-pin SODIMM need to fit?

It requires a standard 260-pin DDR4 SODIMM slot, which is the notebook form factor used in the compatible HP Envy x360 15-aq series laptops.

How is the module installed, and what step do people often get wrong?

Power off the laptop, open the memory compartment, align the notch on the 260-pin SODIMM with the slot key, insert at an angle, then press down firmly until the side clips click — skipping the firm press leaves the module partially seated.
