This week our friends at G.SKILL overnight mailed us their latest RIPJAWS SO-DIMM F3-2133C11D-8GRSL memory kit straight from Taiwan. This is the kit that was announced in November 2013 and it is just now coming out. Just moments after receiving the kit, we popped it into the Intel NUC to see if it would work. We weren't expecting the system to post, but after several seconds we found ourselves on the desktop! After triple checking everything, we discovered that we were really running at 2133MHz! We were excited by this as neither Intel or G.SKILL have never been able to get 2133MHz memory working in dual-channel on the Haswell powered Intel NUC kits! So what changed? Read on to find out!
