Speed DDR4 2666 (PC4 21300)

CAS Latency CL19

  • 32GB dual-channel capacity for multitasking headroom
  • DDR4 2666 speed delivers fast data transfer
  • CL19 19-19-19-43 timing for responsive performance
  • 20V low voltage reduces power draw
  • 260-pin SO-DIMM fits standard laptop slots

32GB DDR4 2666 SO-DIMM Kit

This G.SKILL Ripjaws kit delivers 32GB of laptop memory across two 16GB modules. It runs at DDR4 2666 with CL19 timings and operates at 1.20V. The 260-pin SO-DIMM form factor fits standard notebook slots.

Upgraders needing 32GB dual-channel DDR4

Builders who want a matched 2×16GB kit at 2666 MT/s will find the specifications aligned. Systems limited to lower maximum speeds or single-slot configurations cannot use the full capacity or dual-channel benefit.

DDR4 2666 speed rating

The modules are rated for 2666 MT/s (PC4-21300) with 19-19-19-43 timings. A laptop that only supports slower DDR4 grades will run the kit at the lower supported frequency instead.

Questions about this item

Will the 1.20V SO-DIMM modules need any firmware updates or component swaps later?

No firmware or component swaps are required; the 1.20V DDR4 SO-DIMMs run at their rated 2666 MT/s CL19 19-19-19-43 timings for the life of the kit.

What limit appears first when the 32 GB dual-channel kit runs at full load for hours?

The CL19 19-19-19-43 latency ceiling is reached before bandwidth or voltage headroom becomes a bottleneck.

How much heat and power do the two 16 GB sticks produce during all-day operation?

At 1.20V the pair draws minimal power and runs cool because the modules have no heat spreader and are unbuffered non-ECC DDR4 SO-DIMMs.
