As one of the top memory manufacturers, Adata’s limitations for U.S. buyers have always revolved around marketing and availability. Both of those impact the XPG Spectrix D41 DDR4-3200 kit we're looking at today, as the black/dark grey kit with this data rate disappeared from most U.S. outlets at the same time as one of Adata's competitors, Patriot, was rapidly dropping prices to outmaneuver speedy higher-data rate kits. Adata’s identically configured red-colored Spectrix D41 DDR4-3200 kit is still a good value at about $190. But competing kits offer better performance for as little as $16 more.
