G.Skill thinks that 64GB still isn't enough for a single memory kit, and it's now releasing a 128GB DDR4 kit targeted at Intel's X99 platform. Yes, one hundred and twenty-eight gigabytes, a figure larger than many SSDs. 16GB DIMM support for Haswell-E CPUs and X99 mobos isn't official, but at least one board maker has enabled it with a BIOS update, and it seems likely others will follow suit.
The kit contains eight 16GB "Ripjaws V" DIMMs clocked at 3000 MT/s. Latencies are set at CL14-14-14-34, which are pretty low numbers considering the speed and per-DIMM capacity. Voltage is set at 1.35V, and the sticks come with XMP 2.0 profiles built in to make for easier setup.
Unsurprisingly, G.Skill is targeting these DIMMs at users working on 3D rendering, content creation, and other professional applications. There's no word on pricing, but given that a similar 64GB kit will set you back $430, we're betting this kit will end up north of $700-$800. You can get your hands on these sticks by the end of January.
