what dose 64mb and 128mb look like?

Answer 1

Memory of the same type (types being DDR, DDR2 and so on) will generally look alsmost exactly identical, with the only differences being that some sticks may have chips on both sides of the circuit board while others may not. This is not a good indication of memory capacity though.

Often, aside from a sticker on the memory sticks, the only difference between them will be in the ident numbers on the memory chips.

Answer 2

You can't look at memory and see how big it is, as long as it is not written onto. Just put it into a computer and look at the messages during boot up.

Or use software installed. When using windows right click on My Computer -> Properties there is somewhere the amount of memory in the computer.

I guess, that is your question, as your question is rather unspecific and not tagged with anything helpful like the type of ram or your operating system if you have any. I do not even know, why i even bother to answer to that question.

Answer 3

If the sticks still have their stickers, you might identify them through the part-number.
