Keep your notebook moving with this PNY 4GB DDR3 RAM stick. The low 1300MHz frequency speed helps to reduce temperatures across the laptop while ensuring it still has enough speed to keep data flowing to important programs. Each PNY 4GB DDR3 RAM stick is ideal for motherboards that have 1.5-volt RAM slots.
over all i would say that, except for this one problem that was i suppose random, that this is some great ram for the price and it performs very well. The problem that occurred with this RAM FOR ME in this case was that it was causing my computer ( a 2011 MBP 13' i5) to have recurring kernel panics (basically freezes my computer and forces me to reboot). This happened to me once the very day i installed it and I optimistically tried to not blame the ram. However, after more research and 3 more kernel panics I found that it was indeed the recent installation of RAM that had cause this problem i have since returned the PNY RAM and traded it in for some Crucial brand RAM and that has been working quite smoothly. in conclusion i would say that it was just bad luck on my end and i just got that one bad apple but i didn't want to take another chance with the same brand. I don't mean to discourage potential buyers just a subtle warning
What's great about it: price and performance
What's not so great: in this case, it caused my computer to freeze
