I want upgrade my laptop (DELL Latitude E6430, 14") from its current processor intel i5-3340M @ 2.70GHz to intel i7-3540. I also want to add an extra DDR3 SODIMM 8GB RAM 1600 to make it 16GB RAM overall. I want to know if this will be possible for my laptop and whether or not its compatible.

The CPU upgrade I want to buy is from Aliexpress: https://www.aliexpress.com/item/32843133615.html?spm=a2g0o.cart.0.0.5fbb38daRndXIl&mp=1

I'm not an expert in replacing and upgrading hardware and would appreciate if someone could tell me what steps I should take once receiving the RAM and CPU chip if its feasible.  

I also intend to buy a bigger capacity battery at some point because my current one (5200mAh) drains quite quickly. 

Thanks
