With Skylake bringing DDR4 to mainstream desktops, Kingston has updated another one of their product lines to the higher standard. Previously, the company had a line of XMP-compatible RAM with a low heatspreader, called Fury, and a line of high-performance sticks with tall heatspreaders. This means that there was no combination (from Kingston at least) that brings 3 GHz RAM to systems with big CPU coolers that hangs over RAM slots.
As expected, kits are available all the way up to 64 GB (8x8GB). That pack is rated at 2800 MHz with a CAS latency of 14, versus the highest-bandwidth 3000 MHz kit (4x8GB) with a CAS latency of 15.
The RAM is supposedly available now, but I cannot find any listing online. Overclockers claims that they found a 2 x 4GB kit on Newegg.com for $72 USD, but I cannot verify that because the listing appears to have been removed. Kingston HyperX Savage DDR4 comes with a lifetime warranty.
