I’ve got a processor i7-4771 SR1BW 3.5GHZ that was an iMac 2013 and would like to know if I can upgrade that. This is my specs at the moment iMac (27-inch, Mid 2011) Processor: 3.1 GHz Intel Core i5 Memory: 8 GB 1333 MHz DDR3 Graphics: AMD Radeon HD 6970M 1024 MB Storage: Fusion (Samsung Pro SSD 250GB + 3TB SATA) Thank you.
refer to : iMac Intel 21.5" EMC 2638 Teardown you are not able to upgrade the cpu, because its soldered into motherboard. Thanks.
