I need to expand the Ram. My inspiron 530 has 2 Gb ram and this is not enough for Photoshopping activities. I want to buy 2 x 1Gb extensions for the ram, but to succeed I must had two additional free slots.
According to the spec sheet on the inspirion 530 it has 4 slots and comes with 2 slots filled with a set of 2 - 1Gb. DDR2-667 modules so you should have 2 empty slots that you could fill with 2 more 1Gb. DDR2-667 modules to give you 4 gb. (though if you have a 32 bit OS only 3.25 gb. or so will be useable)
