"A memory upgrade is one of the fastest ways to make a system feel new again. G.Skill F4-4000C18Q-32GTZRB is built for exactly that kind of practical performance boost. The G.Skill F4-4000C18Q-32GTZRB is a kit of four 8GB DDR4-4000 (PC4-32000) memory modules from the Trident Z RGB series. The total capacity is 32GB. The modules support timings of 18-22-22-42 at 4000MHz and require 1.35V. A feature of the Trident Z RGB series is the individually adjustable RGB LED lighting. Intel's XMP memory profile version 2.0 is supported. You get the biggest payoff in the moments that usually feel slow: multitasking, heavier browser use, and the general responsiveness that makes a laptop or compact PC feel snappy again. Useful at a glance: Capacity 32 GB (4 x 8 GB) Voltage 1.35 volts (from 1.2 to 1.35 volts) Standard DDR4-4000 (PC4-32000). A solid choice when you want the benefits to show up in everyday use, not just on a spec sheet."
