32GB DDR4 SODIMM kit

This 32GB kit contains two 16GB DDR4 SO-DIMM modules rated at 2400MHz with CL17 timing. It is built for Acer Predator Helios 300 models PH315-51-78NP, PH315-51-56KX and PH315-51-74V4. The non-ECC, unbuffered design matches the original specification for these notebooks.

260-pin DDR4 installation

Each stick uses the standard 260-pin SO-DIMM form factor and runs at 1.2V. The kit fills both memory slots in the compatible Helios 300 chassis, so no empty sockets remain. Because the modules are unbuffered and non-ECC, they drop straight into the existing slots without BIOS changes or additional cooling.

32GB maximum capacity

The two modules reach the 32GB ceiling supported by the listed Helios 300 systems. Dual-rank 2Rx8 organisation helps density, but the kit cannot exceed the platform's two-slot limit. Buyers who want more storage than 32GB or who need ECC error correction will need a different platform.

Questions about this item

Does the 1.2 V DDR4 2400 MHz kit stay within the laptop's thermal limits during long sessions?

The modules run at the standard 1.2 V DDR4 voltage and have no heat spreader, so they rely on the Helios 300's existing cooling to manage temperature during sustained use.

How much fan noise or extra heat should I expect after installing both 16 GB sticks?

The memory itself produces minimal heat at 1.2 V and CL17 timings, so any additional fan activity will come from the CPU or GPU workload, not from the RAM.

My Helios 300 PH315-51 currently has one 16 GB stick — can I just add one of these modules?

This kit is sold as a matched 2 x 16 GB pair; for guaranteed compatibility with the PH315-51 models listed, both slots should be populated with the two sticks together.
