G.SKILL Introduces 4000MHz SO-DIMM DDR4 Kit

Not to be outdone by Corsair, G.SKILL has also announced their own set of 4000MHz SO-DIMM DDR4 memory kit. These are available as a 32GB (4x8GB) pack with CL18-18-18-38 timings. These make them faster than Corsair’s 4000MHz kit since those have CL19-23-23-45 timings at 1.35V. G.SKILL’s 4000MHz SO-DIMMs are part of their RIPJAWS line, use Samsung B-die DDR4 ICs and run at 1.35V.

Fastest SO-DIMM DDR4 So Far

The new 4000MHz beats their previous record of 3800MHz CL18 kit announced two months ago. These quad-channel kits are of course ideal for high performance laptops or ASRock’s X299E-ITX/AC Mini-ITX motherboard. So far, ASRock is the only motherboard manufacturer who has such a product that can use these SO-DIMM kits. As usual G.SKILL provides a memtest screenshot showing the kit running at the actual rated speeds.

Pricing and Availability

The 4000MHz CL18 setting is easily loadable via XMP 2.0 on supporting Intel systems. Pricing as usual is always in flux, but prepare to pay somewhere in the neighbourhood of €610+ EUR. The kit itself will be available in Q1 2018. Like all G.SKILL memory kits, these RIPJAWS SO-DIMM DDR4 modules are covered with a limited lifetime warranty. That means if they do not work as advertised on the rated speeds, feel free to return them or have them replaced.
