Speed DDR4 2666 (PC4 21300)

  • 128GB total capacity from four 32GB modules
  • DDR4 2666MHz speed rated at PC4-21300
  • CL19 latency timing at 1.2V standard voltage
  • 288-pin DIMM form factor fits desktop motherboards
  • Quad-channel kit enables multi-channel bandwidth

128GB Quad-Channel DDR4 Kit

This 128GB kit contains four 32GB DDR4 modules built for desktop systems. It targets users who need maximum memory capacity for virtualisation, content creation or heavy multitasking. The quad-channel layout delivers full bandwidth on compatible platforms.

Tested 2666MHz CL19 Timing

Each module is validated at 2666MHz with a CAS latency of 19 and runs at the standard 1.20V. This speed and timing combination is the single specification that determines whether the kit matches your motherboard’s supported memory profile.

Standard-Voltage Unbuffered Operation

The non-ECC unbuffered DIMMs operate at 1.2V without a heat spreader, so thermals stay close to stock DDR4 levels. Power draw remains low during typical workloads and the modules produce no additional acoustic noise.

Questions about this item

Will this 128 GB quad-channel kit work with my Intel Core i7 desktop?

The kit uses standard DDR4 2666 MHz UDIMM modules at 1.2 V and is listed as Intel compatible, but you must confirm your motherboard supports 32 GB per slot and quad-channel operation.

Can I populate all four slots on a dual-channel motherboard?

Yes, the four 288-pin DIMMs will install in four slots, but the board will run them in dual-channel mode; total capacity remains 128 GB at 2666 MHz CL19.

Is any BIOS update required before installing these modules?

Some platforms need a BIOS revision to recognise 32 GB density DIMMs; check the motherboard vendor’s support page for the latest firmware before upgrading.
