Speed DDR4 2666 (PC4 21300)

CAS Latency CL19

  • 128GB total capacity from four 32GB modules for heavy multitasking
  • DDR4 2666MHz speed rated at PC4-21300 for fast data rates
  • CL19 latency at 1.20V standard voltage for efficient operation
  • 260-pin SODIMM form factor fits compatible laptop memory slots
  • Tested with major-brand DRAM ICs for dependable reliability

Capacity and purpose

This kit provides 128GB of DDR4 laptop memory across four 32GB SODIMM modules. It suits users who need a large memory pool for virtualisation, heavy multitasking or content workloads on compatible notebooks and all-in-one PCs.

What the kit changes

Four matched modules let a quad-channel capable platform interleave data across all sticks, raising usable bandwidth versus a smaller or mismatched set. The CL19 timing and 1.20V operation keep latency and power draw at standard DDR4 levels.

Build and connectors

Each module uses the 260-pin SO-DIMM edge connector with unbuffered, non-ECC signalling, so it fits the SO-DIMM slots found in many laptops and compact desktops. No heat spreader is fitted, keeping the profile low for tight chassis clearance.

Questions about this item

Will the four 32GB modules need any periodic re-seating or cleaning?

No, the unbuffered DDR4 SODIMM modules have no moving parts or heat spreaders that require maintenance; once seated in the 260-pin slots they remain in place for the life of the system.

What limit appears first when the kit runs at 2666 MHz under continuous load?

The CL19 latency at 1.20V sets the timing ceiling; sustained bandwidth is capped by the PC4-21300 rating of each 32GB module.

How much heat and noise does the 128GB kit produce during all-day operation?

The modules run at standard 1.2V DDR4 voltage without heat spreaders, so they generate minimal heat and zero audible noise inside a laptop chassis.
