How high will memory makers take DDR4 RAM kits? We're in the process of finding out. In the meantime, G.Skill is laying claim to the world's fastest DDR4 memory with its new Ripjaws 4 DDR4-3333 memory kit (F4-3333C16Q-16GRK). It's a 16GB kit consisting of four 4GB modules for quad-channel fun on your new Intel Haswell-E build with 16-16-16-36-2N timings and 1.35V.
G.Skill says its RAM is fully validated on the newest Asus Rampage V Extreme X99 motherboard, though it should work on other motherboards built around Intel's X99 chipset as well. It also features Intel XMP 2.0, meaning you shouldn't have to fuss with settings in the BIOS.
You can also pick up a Ripjaws 4 kit clocked at 3300MHz (F4-3300C16Q-16GRK) or 3200MHz (F4-3200C16Q-16GRK) for a bit less money. They're also quad-channel kits consisting of four 4GB modules with the same timing.
The 3200MHz ($470) and 3300MHz ($580) are available now; the 3333MHz kit should be available soon for $700.
