Inspiron 3520 i3 processor upgrade?

This question has been answered by billwx

I would like to upgrade the processor in my Inspiron 15 3520 from i3-2350M to max. I read online the i5-3230M was best for this machine. Is this correct? It does have the same G2 socket. Also, any chance of upgrading to i7 with this machine? I assume quad core is out of the question? Thanks much!

  • I have successfully upgraded my Inspiron 15 3520 processor from i3-2350M to i5-3210M (less than $30. at online auction). Maybe it's just me but i find Firefox web pages load and switch much faster/smoother. My photo application loads a folder of hundreds of pics in about the same time as before, but cropping is also much faster/smoother. It was def worth the price/work/learning experience. Unfortunately i introduced another problem (for which i will seek resolution in another thread) by my own error/impatience.

  • Hi billwx,

    Thanks for posting.

    Unfortunately, no, that would not be possible, as the processor is soldered to the motherboard.


  • On the 3520, the CPU is socketed -- not soldered (it is soldered on most subsequent models).

    The second (sandy bridge) and third (ivy bridge) CPUs should work - up to 35W max power required.

  • For the information of anyone who sees this answer and has the same question, I can report that the i5-3380M also works successfully in an Inspiron 3520. I installed one in an old 3520 last week and am using the machine to type this answer.

  • Any chance of upgrading to an i7?

  • It was never shipped with an i7 - and given the other limitations of the system, it's likely not worth trying.  All the i7 would do is emphasize the real limit of the system - the hard drive (assuming it hasn't been upgraded to a solid state drive) and the weak GPU (which will be the same on an i7 as on an i5).
