I recently got a free machine. But it came without any ram. Im presuming I cant boot it without or I could answer the question myself. Ive got the code from the bottom (model no: a1177 emc no: 2023) But this leads me to 3 choices. 2.0, 2.3 or 2.5. Inside is a sticker that warns to unplug it if any liquid is leaking from it. I dont want to waste cash on the wrong ram. Does this mean its a 2.5 dp. Or am I way off track. Cheers for any help in advance.
