Micron

Micron 64GB (2x32GB) DDR4 2666MHz laptop RAM

SKU CH-ZDEN-JHA79

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.

Questions about this item

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.
