The unit looks good and has a decent processor for the price, but it's very picky about RAM. Not only do you need a RAM with proper frequency and voltage, but you need to worry about density. It doesn't say anywhere in the description of the NUC, but it seems to only take RAM with high density (4gb). It gets more complicated, as RAM manufacturers don't add the density detail to their product page, and usually puts a sticker/cover on the RAM to visually guess the density. For example: a 4GB ram that has 8 chips per side has density 2gb, whereas a 4GB ram that has 4 chips per side has 4gb density. I bought a Corsair ram that appeared perfect to pair with it, but it didn't work, I only got error "1Gb or 2Gb density error" at POST. Wish Intel didn't cut corners with the type of supported rams.
