HP520 Notebook RAM Upgrading Limits/Care, Maintenance, Dismantling And Service Manual pdf.

One of my laptop is HP 520. I am using it from last 2 years. Now I wanted to upgrade the RAM, and that’s why I wanted to know that how much RAM is supported by HP520 laptop/notebook. The laptop with all accessories is working fine. I was wondering about the changing or up gradation of the RAM in the HP520 laptop from 1 GB to 2 or 4 GB. The first important thing which came into my path was to find out the maximum support of the RAM capacity for this laptop (laptop HP 520). As the technology is very fast changing these days, so the use and the users are also changing with the same respect. These days because of 3G networks on the mobile phones we can Watch / View Live TV Programs on our Mobile Phones, and Computers / Laptop, can Watch your Favourite Zee TV Shows, Serials and Programs for Free on your Laptop / Computer , can have Video Chats or Video Calls on Mobile Phones and Computers. Previously I was having 6 Powerful Browsers on my Desktop and Laptop but now the number of browser is increased by one; and now I have 7 browsers and the new one is Epic Browser, Even the NASA Scientists are Tweeting from Space, Can Translate any Language into Any Other Language for Free. These days laptops are using 4 GB of RAMs or even more than this. The technology is very fast changing, isn’t so? My HP 520 laptop is having a decent configuration with 1 GB of RAM.

*You should keep in mind some points; if you want to change the RAM of your laptop or Desktop PC.

Always try to replace RAM with the same type like DDR1 or DDR2 or DDR3 etc (which you already have into your laptop or into your desktop) with the same DDR type while increasing your RAM capacity, i.e. 1GB to 2GB or 3-4 GB etc don’t try to mesh up DDR2 with DDR3.

If you are inserting two modules of RAM into the two slots say 512 MB + 512 MB or 1GB + 1GB than get both RAM of the same speed like 1 GB 400 MHZ + 1 GB 200 MHZ or whatever you have from beginning into you Notebook or Desktop(get 2 RAM sticks of the same speed) with increased memory capacity. If you will insert slower RAM with the faster RAM than it will automatically slow down the faster RAM module to the same speed as your lower speed RAM have. To get the good and maximum performance of RAM into your notebook/laptop/desktop it should be of the same configuration.

These are the basic and the important criteria of changing the RAM of your Pc, but always try to consult your hardware provider, or any laptop/desktop service engineer if you have any doubt.
