  • 32 GB total capacity for heavy multitasking
  • DDR4 2666 MT/s speed boosts data throughput
  • CL19 latency with 1.2 V operation saves power
  • 260-pin SO-DIMM fits standard laptop slots
  • 100 % factory tested for reliable operation

Capacity and form factor

This kit provides 32GB of DDR4 laptop memory as two 16GB modules. Each stick uses the 260-pin SO-DIMM form factor designed for notebook slots. The memory runs at 2666 MT/s with CL19 timings at 1.20V.

Unbuffered non-ECC design

The modules are unbuffered and non-ECC, matching the requirements of most consumer laptop platforms. Dual-rank x8 organisation allows the density needed for 16GB per module. No heat spreader is included, keeping the profile low for tight chassis.

DDR3 bottleneck and voltage limit

The DDR4 standard replaces DDR3, which has been a limiting factor since 2007. Operating at 1.2V instead of 1.5V reduces voltage by 20% and can lower overall power draw by up to 40%. Systems that only accept DDR3 cannot use these modules.

商品問答

Will the modules need a heat spreader added later to handle sustained loads?

The kit ships without a heat spreader; DDR4 SO-DIMMs at 1.20 V run cool enough in typical laptop chassis that extra cooling is not required.

What limit appears first when the memory runs at 2666 MT/s for long periods?

The CAS latency of CL19 (19-19-19 timing) sets the response-speed ceiling before bandwidth or voltage become constraints.

How much power and heat will the 32 GB kit draw during all-day use?

Operating at 1.20 V, the dual-rank modules consume up to 40 % less power than DDR3 at 1.5 V, reducing both heat output and battery drain.
