Re: Which is better for my laptop? PC3-14900 or PC3-12800. Does it make a difference?
Thank you for your message. Both parts are guaranteed to be compatible with your system. The you would not notice a big difference in performance from the different parts. PC3-14900 is the fastest but I would recommend PC3-12800. I would recommend this, as I see that you already have 8GB installed. The PC3-1288 would be most compatible with your existing memory module.
I hope this answers your question and we do have a great support and guide section on our website that you can see HERE
If you do have any other questions at all, please don't hesitate to ask and I would be more than happy to help.
