Could someone please help me identify this memory?
It is from a (don't laugh) Mecer notebook which is about a year old. There are two stickers on the memory chip:
Sticker 1: DDR4-512
Sticker 2: 512mb PC400
sticker 1 is probably mecers own stock sticker, and i would translate is as
ddr400 512mb sodimm (small outline dimm, i.e. laptop memory), which is what others know as pc3200
the 512mb pc400 sticker is probably from the original manufacturer, who knows what they are trying to imply.
