Targeted laptop upgrade

This 8GB DDR4 SODIMM module is built for Acer Predator Helios 300 models including PH317-52 and PH315-51 series. It suits owners who need a single stick to fill one slot or replace an existing unit. The non-ECC unbuffered design matches the original specification for these notebooks.

Slim stick fits tight slots

The 260-pin form factor has no heat spreader so it slides into shallow SO-DIMM sockets without clearance issues. Standard 1.2V operation keeps power draw low and thermals simple inside a compact chassis. Major-brand DRAM chips are used on each module supplied.

DDR4 2400 ceiling limits bandwidth

The PC4-19200 interface tops out at 2400 MT/s with CL17 17-17-17 timings, so throughput cannot exceed that ceiling. Dual-rank 2Rx8 organisation helps density but does not raise the frequency wall. Systems capped at 32GB across two sockets will not accept larger kits.

Questions about this item

What speed does the DDR4 2400 SODIMM run at in an Acer Predator Helios 300?

The module operates at 2400 MHz (PC4 19200) with CL17 timing; the laptop's memory controller sets the final speed.

Will this 260-pin SODIMM fit the Helios 300 PH315-51 and PH317-52 models?

Yes, the 260-pin DDR4 SO-DIMM form factor matches the two SODIMM slots in those Helios 300 chassis.

What is the correct way to seat the module so the retention clips lock?

Insert the stick at roughly 30 degrees, press down firmly until both side clips click into the notches.
