G.Skill has one of the largest and most respected DDR4 memory kit lineups on the market and they are always trying to develop and release faster memory kits for enthusiasts. The G.Skill Trident Z series of memory was designed specifically to offer extreme performance applications and feature the best Samsung DDR4 ICs that G.Skill could purchase. G.Skill than sorted/binned all the Samsung IC's that they purchased and came up with 11 different speed grades ranging from 2800 MHz to 4266 MHz with regards to 8GB (2 x 4GB) dual-channel DDR4 memory kits that we are going to be focusing on today. With that many speed grades available it basically forces the enthusiast to purchase a memory kit by the price of the kit as most of the sorting fun was done at the factory. The kit that we will be reviewing today is the G.Skill Trident Z 4000MHz 8GB (2x4GB) memory kit that is sold under part number F4-4000C19D-8GTZ for $209.99 shipped.
