Can I add 512MB more RAM here?

I just got a 2.16Ghz MBP with 2GB RAM already installed. My question is: Are there enough slots to add just 512Mb RAM (2 sticks total) in addition to the 2GB RAM (another 2 sticks total)?

Use this website to find your MBP. Once you find it, it should tell you the RAM configuration your Mac was by default and how many slots there are.

If I understand your post though, you want to add 2x512MB to the already existing 2x1GB. Without knowing the official specs of your MBP, I can tell you already that it doesn't have 4 slots.

They dont just put 2gb sticks in one slot it comes with 2 1gb sticks so no you cant add an extra stick. You can take out a 1gb stick then add a 2gb stick if you want tho.

True but it is highly recommended that RAM is paired - ie. you have two sticks of the same size.

yea thats right so if you want to increase your ram just buy two 2gb sticks they should be pretty cheap
