laptops can be tricky even if it is the same socket. if the laptop never had the option of coming with an I7 then it may not support it because of the BIOS is only coded to work with certain CPU's

but if that I7 is a 6th gen CPU and the I5 you have is 4th gen as it looks like from the model names then it will definitely not work

i7 46om is i believe 1st gen same with i5 460m... regarding the option if laptop came out if it got i7 im not sure of it.

I did 450m -> 640m. The result was a much snappier system that runs hot (stupid Dell coolers). My BIOS supported it without any complaint. Dell Studio 1569.

Still not as quick as my Sandy Bridge i7, though.

@dudeman - so it`s not worth it?? i already added a SSD and RAM upgrade... So that should be it??

dudeman509 :

keep in mind you did this with a dell laptop and he is trying to do it with a Sony Vaio which means there is still no guarantee it will work

so @captainshcarisma can i upgrade it and is worth it?

kogkog_bugart :

if you can get it for cheap then it would be. make sure it comes with a fan because the fan from your old CPU may not cut it

It was absolutely worth it. I use that computer every day (also SSD and 8 GB RAM) and it made a noticeable difference in web browsing, etc. The 640m has a stock clock 400 MHz higher than my chip, and turbo boosts 800 MHz higher. That is enough to notice a difference!

The Nehalem chips just run hot, and as it's a thin laptop, the cooler pipe isn't the best. Make sure you get a decent thermal paste.
