Hi guys I have a toshiba satellite c660-1EL that I am currently running ubuntu in, and I want to do an upgrade for a ram but I dont know which ram sticks I should buy. I want to know do all toshiba satellite c660 models share the same types of ram sticks? Will it hurt if I took CL9 or CL11. Also I would like it if someone can help pick the best ram sticks from this online store. Thanks!!!.
Here are my specs for ram compatibe to my system.
Specifications:

  • 4GB DDR3 PC3-10600 1333Mhz

  • Non-ECC

  • Unregistered

  • CL9

  • 204 Pin
