G.Skill this past week has formally announced its quad-channel memory kits designed for the latest Intel Core i7 (Skylake-X) CPUs and the Intel X299 platform. The flagship 64 GB Trident Z kit boasts a 4200 MT/s data transfer rate, a rather notable step up from the companys "entry-level" 3600 MT/s kit. In addition, G.Skill is also introducing its new Trident Z Black series dual-channel DDR4-4400 kit for Intel's Kaby Lake-X processors.

G.Skill's lineup of memory kits for the Intel X299 platform consists of 8 GB and 16 GB Trident and Trident Z RGB DIMMs based on Samsung's popular 20nm-fabbed 8 Gb DDR4 DRAM modules. The various kits are available at 3600 MT/s, 3733 MT/s, 3800 MT/s, 4000 MT/s, and 4200 MT/s data transfer rates, while their voltages run from 1.35 to 1.4 V. As youd expect, the higher clocked kits also come with higher latency, with latencies starting at CL16 and reaching CL19 by DDR4-4200 speeds. Which goes to show that even though Intels Skylake-X and Kaby Lake-X CPUs can handle very high DRAM frequencies, the tradeoff between clocks and timings has not gone anywhere.
