G.Skill Announces DDR4-4000 and DRAM in Dual Channel Kits
 

At this point in time, the only commercial platform that runs DDR4 is the Haswell-E processor combined with the X99 chipset. For that platform, the processor has a quad-channel memory controller and in order to extract the best performance, four memory modules are needed – we published a large breakdown on the effect of the DDR4 memory speed on this platform earlier in the year.

Despite this, G.Skill is today announcing its upcoming memory kits – specifically ‘designed for 6th Gen Intel Core Processors and Z170 motherboards’, or what the rest of us calls ‘Skylake’. These new kits fall into two series called ‘Trident Z’ and ‘Ripjaws V’, with the Trident line being typically faster than Ripjaws although there will be crossover. Memory companies usually do this in order to enable users who prefer one style over the other but still want a certain speed.
