64 GB dual-channel DDR4 SO-DIMM kit running at 2666 MHz with 1.2 V operation for lower power draw

  • Capacity64GB (2 x 32GB)
  • Type260-Pin DDR4 SO-DIMM
  • Faster application loading with DDR4 2666MHz speed
  • Smoother multitasking from 32% higher memory bandwidth
  • Lower system power draw at 1.2V operating voltage
  • 64GB total capacity across two 32GB modules
  • 260-pin SO-DIMM form factor fits compatible laptops

Capacity and compatibility

This kit provides 64GB of DDR4 laptop memory in a matched pair of 32GB modules. It is built for the Acer Predator Helios 300 models PH315-51-78NP, PH315-52-72RG, PH315-52-78VL, PH315-52-710B and PH315-53-72XD. Buyers whose laptops use a different slot layout or maximum capacity cannot use this kit.

Build quality and daily use

The modules use a 260-pin SO-DIMM form factor with registered DDR4 circuitry and run at 2666MHz under the PC4-21300 specification. Operating at 1.2 volts, they draw less power than older standards. Systems that require unbuffered SODIMMs or a different pin count will not accept these sticks.

What the bundle changes

The package contains only the two memory modules; no tools, adapters or software are included. Installation is a straightforward hardware swap that immediately raises the memory ceiling to 64GB. Users who need diagnostic utilities or firmware updates must obtain them separately.

商品問答

What speed does the DDR4 PC4-21300 rating deliver on this kit?

The modules run at 2666 MHz, the data rate defined by the PC4-21300 specification.

What slot type and pin count do these modules require?

They are 260-pin DDR4 SO-DIMMs, the standard form factor for laptop memory slots.

How are the two 32 GB sticks installed, and what mistake should I avoid?

Insert each stick at an angle until the gold contacts disappear, then press down until the side clips click; the common error is stopping before the clips engage.
