HP TouchSmart 520-1010uk Upgrade

[APL01]

I am considering upgrading my HP TouchSmart 520-1010uk, as it is creaking at the seams. It currently has 4GB DDR3-1333 RAM and a Pentium G620 processor. The HP website suggests that the RAM can be upgraded with a 2nd 4GB, and the processor to "Core i5-2400s (Sandy Bridge) quad core" or "Core i7-2600s (Sandy Bridge) quad core". I have a few questions:

1. There appear to be a variety of sized (different pins) RAM memory modules that appear to match this specification (DDR3-1333). Which one do I need to get for the HP TouchSmart 520-1010uk?
2. I have found a "Core i5-2400s (Sandy Bridge) quad core" at a reasonable cost. Please can you advise as to whether the current fan is suitable for this processor?
3. Are there any instructions for upgrading the processor - I can only find instructions for updrading the RAM and HD?
4. How much quicker is this likely to make the PC i.e. is it worth upgrading?

Thanks

Welcome to the HP Forums 🙂 

I would like to take a moment and thank you for using this forum, it is a great place to find answers & meet like minded tech enthusiasts! 

I've reviewed your post and though the device can be customized or upgraded, I must let you know that HP doesn't recommend it, as the device is set to work at its optimal performance:

Upgrade information listed on the HP website is for your ease, in case you wish to upgrade either way: Click here for details and look under upgrade information for processor & memory (tested & approved by HP to work on your device).

Personally, Its not worth upgrading as the device is obsolete and getting a new device would be more efficient then going through the trouble of finding parts, investing both time and money on the same.
