The make of this 1GB memory is the same as the original 512MB that came with my Dell D400 just with a play sticker on it, Hyunix is a standard brand Dell originally used for there laptop memory. Works well. Massive improvement to computer. Can load more tabs up on browser. Specially video's such as youtube. Get it from here than ebay. Chances are the sellers have bought a load of these and taken the sticker off.
