Can I upgrade my PC processor i5 1st gen to i5 4th gen.....i have HP Z200 model and processor is i5-650......can I upgrade it to 4th generation is this possible........
No that is not possible. 1st gen needed a LGA1156 socket, which is only used in 1st gen. 4th gen needs a LGA1150 socket. The only way to upgrade your CPU is to get an i7 1st gen or a better i5 1st gen. Like a i7-860.
500 bucks you can get a complete build using Ryzen and more ram you wouldn't recognise the performance. Seeing youre kinda desperate for 4th gen and Ryzen being budget friendly, why not?
