Rispondi a "Is it possible to upgrade CPU from core i3-3225 to core i7-3770s"Hi all and Dan, today I opened up my Early 2013 iMac 21.5”, because it is having some problems with the display (or graphics) not turning on. I wanted to check if the CPU is socketed because there are many different answers online. I can confirm that the CPU is socketed, just like any other socketed CPU. I hope this helps many others who are having troubles with their iMacs and who are not able to find a clear answer about whether the CPU is socketed or not. I will be upgrading mine to a Core i7 3770 to have an upgrade and to (hopefully) resolve my issue.
