    I bought some third party Crucial 4GB of Ram for my UBMBP and, I don't know, seems a bit slow for 4G? Almost seems as though my 2g was just as faster or faster? You think maybe the brand or something?

    Or maybe I'm crazy??

    If you still have your original ram do some benchmarks and see which is faster.

    It's slower how?
    Longer boot up times
    or system generally feels sluggish?

    like when, I go to the HD and click on application, it takes longer to be able to scroll in one fluid motion. No big deal, and I guess maybe since I'm looking for something, I might over analyze this and, well. Like I said, it might just be in my head, but I could swear that when it had the 2GB it was ready to scroll right when I clicked it.

    I used OWC 4GB DDR3 upgrade and they work well. Boot up is a little slower as there is twice as much RAM to check. When the spinning wheel just below the Apple logo stops spinning, it blanks for less than a second and the login screen jumps. I swear before the upgrade, here was more than 3 seconds pause before the login screen. Everything else is faster with 4GB in my UbMBP.
    I think PC3-8500 ram is CL7 and timing 7-7-7-20. This is what the MCP79M likes.

    yes, it's in there correctly. No big deal guys, I'm sure it's nothing, I just thought it was kinda strange, you know?

    try resetting the PRAM. It worked for me...Or maybe I just got used to being it slow.
