Picking the correct ddr3 memory for my HP Pavilion 15-b119wm Sleekbook

Thank you for your help. Sorry it took me so long to respond. I ended up moving and honestly forgot all about my post until I was again thinking about needing more RAM. I didn't even know anyone had responded. Anyway, here I am again checking things out. I went to the link for the Mushkin Enhanced RAM and now I have more questions.

I was already looking before I re-found my post and the suggestion. I can't help but want to know why this one? I want to know what is the difference between RAM? Which one will give me the fastest performance? Is the fastest performance what I should be aiming for in the first place? I want to know what do I need to know in order to compare them and make the best choice?

I went to Crucial and ran the scan and it gives me quite a few different choices that are compatible with my hp pavilion sleekbook 15b-119wm. None of the ones they recommend are 'dual channel' like the Mushkin.

I don't really do much heavy gaming but I do like to multi-task quite a bit and have a few programs open at the same time. I've tried several browsers and for some reason I always come back to Opera. At any given time I have about 7 or more tabs open plus I've got like 10 extensions.

2 of the suggestions from Crucial say 'Performance memory for gamers and enthusiasts' the other 3 of say 'increases system performance. Even though I'm not really into heavy gaming wouldn't I want the Performance memory? I do like to edit videos and music while having my browser open checking other stuff.

Below are the choices that Crucial gave me & I not only want to know which is the best choice for best performance but also why please. I really appreciate it. I will make it a point to check back over the next few days so I don't miss any responses. Thanks again. Amanda
