Dell Inspiron N5110 CPU upgrade

You can only use the second-generation i5 CPUs in this system - not the  third or fourth.  The following are known to work with your system:

i5-2410, i5-2520, i5-2540

I too have something of the sort to inquire about,  I have a dell inspiron n5110 intel Pentium B940 and I was interested in getting the i7 2630qm or the i7 2670qm, is It worth going up to an i7 however or would an i5 be sufficient?  Mostly I will be using it for college work and occasionally very light gaming yet I would like it to be super fast.

The 2630QM and 2670QM were definitely shipped with this model.

thanks for your help

Can you tell me wich i7 processor is working with my laptop?

They were shipped with this laptop model but would it work to swap out the Intel Pentium B940 to the i7 ones you listed?  The b940 has a power rating of 35 watts while the i7-2630QM is rated at 45 watts,  I read somewhere that the heat output may be much greater and also you may need to overclock the motherboard to make it run properly as it isn't all that compatible after all, what do you believe?

It is true that an i7 will generated quite a bit more heat.  It's equally true that all an i7 will do is show up the now-outdated GPU in the system (which cannot be upgraded) - if you really want an upgrade, stick to an i5 with the same TDP rating - the system won't run any hotter, it'll cost less and you'll never notice the difference.

The system was shipped with i7 CPUs, so it is possible.  That said, the i7 is more capable than the video chip in the system - which is now quite outdated, so instead of the CPU being the system bottleneck, the video chip will be -- and that cannot be upgraded.

If you want the best you can go with that system, upgrade to an i5 CPU and replace the hard drive with a solid-state drive.   That'll be your best performance/price upgrade.

So are you saying that it is or it is not possible to upgrade to an i7 PROCESSOR? And what do you mean by "It's equally true that all an i7 will do is show up the now-outdated GPU in the system (which cannot be upgraded)"

Ok what if I was to upgrade my motherboard? I found one for 150 euro which includes a discrete Nvidia graphics card which I don't have in mine, also comes with the cpu itself(i7 2670qm) and the heat sink/fan, only problem is would it fit in my laptop...
