Can I upgrade the logic board on my Early 2015 MBP Retina?
My Early 2015 MBP (A1502) which I could only afford the 2.7Ghz/8GB/128GB is getting a bit long in the tooth so to speak. I impulsively ordered a used 3.1Ghz/16GB (820-4924-A) which the listing said is compatible with all A1502 MBPs (Early 2015). I'm confident it should be a one-for-one swap, but aside from the hardware swap, is there anything I need to do software wise? I have strong tech skills when it comes to hardware but am a luddite when it comes to the software side of things. One more thing to note (if relevant), I replaced the stock 128GB SSD with a 512GB oem unit which is working great. Thank you in advance guys, this is such a rad forum and resource!
Also, how much of a performance upgrade should I be reasonably expecting?
