The next few weeks will cover hardware.  This week, it’s types of RAM, These days, you’ll see almost exclusively DDR3 and DDR3L RAM. Don’t place too much concern in which of the two you get. DDR3L uses less voltage, and thus technically could last longer, but the two are basically the same. They are both better than DDR2 (which is better than DDR).

When it comes to size, look for a computer with at least 6GB, preferably 8GB.  Anything past that is a waste of money, which would be better spent on a nice CPU.

If you are looking to upgrade your computer’s RAM (the most common method for upgrading computers), you need to verify what your computer supports.  You can do so by searching for the specs of your model on your manufacturer’s website.  Check if it’s DDR, DDR2, DDR3, or DDR3L (which is backwards compatible with DDR3).  See what the maximum supported RAM is for your computer so you know how much you can upgrade it to.  Desktops use SODIMM RAM, while laptops use SDRAM.

If you want Expresstek to upgrade your RAM (which is recommended for the safety of your computer), this will all be done for no additional charge.
