Can I upgrade the RAM and processor of my laptop Acer Aspire E1-431?
yes you can upgrade your laptops ram upto 8 GB if your cpu has 32 bit architecture or otherwise even more.Be advised that above a certain limit , no matter how much ram you add it does not improve gaming performance.Usually laptops have 2 ram slots so of one is empty you can add a new Ram module. Or you can simply replace existing one with new ram.processor and GPU ( in your case integrated hd graphic card) is soldered on the motherboard and not simply stuck in case of low and midrange laptops and thus can not be altered.Some hard ways to do so are available but very risky and simply not worth it.
Can I change the processor of an E1-510 Acer Aspire from 2.13GHz to 3.0GHz?
Unfourtunately no, however there are a few things you can do to raise those speeds.First of all, try replacing your thermal compound. You may think this has nothing to do with your CPU, but thanks to Turbo Boost from Intel your processor will reach higher clock speeds as long as it has a thermal margin. This step will also help with the heat it produces so it will keep other components safer as time goes by.This is the advanced part, this steps can break your computer so don’t try them if you don’t know what you are doing; you can try looking up for a modded BIOS. Have in mind that this can kill your device so make sure another person has already tested it when you install it. You can also try setFSB, google it and you will find a bunch of tutorials.Good luck!
