How can I tell what RAM will fit my computer?

I want to increase the RAM size of my laptop from 2GB to 4GB. I want advice on company, RAM type(DDR3?) and other things related to buying a RAM.

  • Welcome to superuser. See [memory upgrade](http://superuser.com/search?q=memory+upgrade) - Note: shopping questions ("advice on company") are [off topic](http://superuser.com/faq). RAM type depends on specific machine. Ability to add memory depends on available slots and on machine limits. 32-bit OS can't use all 4GB. – RedGrittyBrick Nov 26 '12 at 10:03
  • Processsor is Core I3, so it is 64 bit.. i want to know the best company name and ram with latest technology – CoderMan Nov 26 '12 at 10:07
  • We all do, but this Q&A site is not suited to *discussions* of "best company name" or "latest technology" - the [FAQ](http://superuser.com/faq) explains. Also, vendors used to sell 64-bit hardware with 32-bit operating systems. It's the OS that matters. – RedGrittyBrick Nov 26 '12 at 10:10

You want a 4GB DDR3 PC3-10600 (or PC3-8500) SODIMM. Any one should do, more or less, but Crucial offers one that is guaranteed compatible for around $19, part number CT2151387.
