Capacity 16GB (2 x 8GB)

  • 16GB dual-channel kit boosts multitasking headroom with two matched 8GB modules
  • CL19 19-19-19-43 timings deliver responsive DDR4 2666 performance at standard voltage
  • 20V operation keeps power draw low and thermals manageable

Ripjaws V 16GB dual-channel kit

This 16GB kit contains two matched 8GB DDR4 modules running at 2666 MT/s with CL19 timings. It targets builders assembling a new system or upgrading an existing desktop that uses unbuffered non-ECC memory. The red aluminium heatspreader keeps the modules at a low 42mm height for cooler clearance. The kit operates at the standard 1.20V DDR4 voltage.

Upgrade from single-channel or lower-capacity sets

Moving from a single 8GB stick to this dual-channel pair doubles memory bandwidth for the same capacity. The jump is worth it when the motherboard has two free slots and the workload benefits from interleaved access. Do not mix this kit with other modules; matched kits are validated to run together as a set. The supported platform list includes AMD X570, X470, B550, B450 and Intel Z690 DDR4, Z590, Z490, Z390, Z370, Z270, Z170 chipsets.

Sustained-load behaviour with aluminium heatspreader

The 42mm heatspreader dissipates heat during extended gaming, rendering or data-processing sessions without throttling the CL19 19-19-19-43 timings. Each kit passes G.SKILL validation on major motherboard brands to maintain stability at the rated 2666 speed over long periods. The low-profile design ensures airflow is not blocked by large CPU coolers during continuous operation.

Questions about this item

Will the 42mm module height clear my oversized CPU cooler?

The Ripjaws V sticks measure 42mm tall, a dimension chosen to fit under most large air coolers without interference.

Which DIMM slots should I populate on a dual-channel motherboard for this 2 x 8GB kit?

Install one module in each primary channel slot — usually DIMM_A2 and DIMM_B2 — so the memory controller runs in dual-channel mode.

Does the aluminum heatspreader need any upkeep after installation?

No maintenance is required; the heatspreader is passive and has no moving parts or thermal pads that degrade over time.
