16 GB DDR4 SODIMM for Acer Helios 300

This 16 GB DDR4 2400 MHz module is built for the Acer Predator Helios 300 PH317-52-78ZL, PH317-52-74KR and PH315-51-785A. It uses a 260-pin SO-DIMM form factor and runs at 1.2 V without ECC or buffering. The single stick upgrades one of two slots in these laptops.

Low-voltage operation keeps thermals modest

At 1.2 V the module draws little power and produces minimal heat inside the compact chassis. No heat spreader is fitted, so airflow from the system fans passes directly over the chips. Silent operation is maintained because the memory adds no moving parts or audible noise.

Two-slot limit defines maximum capacity

The Helios 300 models listed support a total of 32 GB across two sockets. Installing this 16 GB stick fills one slot; adding a second identical module reaches the ceiling. Builders who need more than 32 GB cannot use this platform.

Questions about this item

How do I install the 260-pin DDR4 SODIMM in my Acer Predator Helios 300, and what step is often missed?

Power off, unplug, remove the battery, open the memory door, insert the module at 30 degrees until the clips snap, then reassemble; the missed step is forgetting to disconnect the internal battery first.

Will this 16GB CL17 1.2V module need any maintenance or replacement during its life?

No scheduled maintenance is required; the module carries a limited lifetime warranty against manufacturing defects from Computer Memory Solutions.

What limit appears first when the 2400MHz 2Rx8 kit runs sustained loads in the Helios 300?

The platform caps at 32GB across two sockets, so capacity is the first ceiling you reach under heavy multitasking.
