System-Specific SODIMM for Helios 300

This 16 GB DDR4 module is built for Acer Predator Helios 300 PH315-51 variants. It fits the 260-pin SO-DIMM slot and runs at 2400 MHz with CL17 timing. The single-stick design suits owners who want to reach the platform's 32 GB ceiling without mixing kits.

Low-voltage unbuffered operation

At 1.2 V the stick draws minimal power and produces little extra heat inside the compact chassis. Unbuffered, non-ECC silicon keeps latency tight for everyday gaming and multitasking. No heat spreader is fitted, so airflow from the existing fans passes directly over the chips.

Single-module pack with lifetime coverage

The box contains one 16 GB stick and no additional cables, adapters or software utilities. Computer Memory Solutions backs the part with a limited lifetime warranty against manufacturing defects when purchased directly. Builders needing dual-channel bandwidth should add a second identical module.

Questions about this item

How do I install the 260-pin DDR4 SODIMM into the PH315-51 and what step is often missed?

Power off and unplug the laptop, remove the bottom panel, align the notch on the 260-pin stick with the slot key, press in firmly until the side clips click, then reassemble. The step often missed is fully seating the module so both clips engage.

What maintenance or replacement will the CM2048642400SO need later?

No routine maintenance is required for this 1.2V unbuffered DDR4 module. Replacement is only needed if a fault appears or if you later expand to the platform maximum of 32 GB across the two sockets.

What limit appears first under sustained heavy workloads with this CL17 2400 MHz kit?

The memory controller caps the data rate at 2400 MT/s, so sustained bandwidth tops out at the PC4-19200 ceiling; latency stays at CL17 and the 1.2 V supply prevents thermal throttling on the DRAM itself.
