I typically use G.Skill memory in my NUC’s as I’ve had great luck with the brand in my desktop and laptop for years. However G.Skill has been increasing in price which made me look around for alternatives and came across Crucial DDR3 204-pin memory for less money, but days after I purchased it they too went up in price. However they are now back on sale and cost about $50 less then the G.Skill memory I have been using in my first two NUC’s.
I’ve been using the Crucial memory now for the last several months without any problems and even though they are rated at a lower voltage I can’t say I really see any difference in power savings or consumption compared to the G.Skill 1.5V. If you’re looking to upgrade now might be a good time to take advantage of the sale price.
