If you only changed one, you messed up. Need to change in pairs - or you put them in the wrong slots - or one or both are defective.
enjoy.

*****POSSIBILITIES*****
1). 256mb is the max RAM or less than 512mb is.
2). Your PC requires ram to be installed in pairs.
3). The 512mb chip is the incorrect speed/density/type.
4). The 512mb chip is defective.
Good Luck :-)

if it is dual channel then you must have the same memory configuration on both memory slot sections
also, make sure the memory is either ecc or non-ecc memory, depending on what ur computer is, as this is neccesary for it to work
im not sure if clock speed could possible be an issue, but i doubt it, as im pretty sure u can have multiple cards with different clock speeds
every answer before mine was made by some noob who didnt know what he was talkin about lol

There are many types of ram you need to make sure you have the right kind and sometimes they have to be in the right ram slots for instances in my computer i have four ram expansion slots but if i have to sticks of ram i have to put one in the first slot and one in the third.

Do you have the same pin number as well as style of RAM. Remember, you can't mix 256 with 512 cards. All the same or nothing works.

because somtimes u have to by exactly the same one you had. like 256mb. tae that card to the shop u bought and tell them that u need same one but 512 and they'll give u the right one. coz sometimes computer does not accept all DDRs. hope it'll work out for ya.

This is because you do not have enough internal memory to run a 512mb ram system, you need to either upgrade your pc or add an external harddrive to it, i reccomend you purchase one of the following adress.

Either the ram is bad or you dont have the right stick or your mem slots will only accept 256 megs! Read your manual!

Your voltage setting could be wrong for the new memory. The new memory could be incompatible with your system.
