    I have late 2008 macbook 5.1...
    I installed 2GB+4GB=6GB RAM Kingston 1333MHz pc3-10600 modules

    The originals were: 1GB+1GB=2GB 1066MHz pc3-8500 modules

    The MHz and pc3-8500 are different in numbers. I want to know will I have troubles? My computer is functioning now fine and the system profiler identified it with status OK .

    The other thing is that I bought Kingston as I thought they were one of the best RAM manufacturers out there. But I heard OWC and Crucial is which I should buy.

    Sorry, first time to install new RAM

    If everything works fine, then there is no need to worry. RAM can underclock itself so the 1333MHz modules can run at 1066MHz if the IMC doesn't support higher speeds.

    There is no best RAM manufacturer. For me, the best one is the cheapest one. Most RAM is the same anyway with a different logo on it. As long as it comes with lifetime warranty, I'm fine with it.

    On the fence
    Like Hellhammer said, if it's working fine, then there is no need to worry. Kingston works just fine, and the computer will either operate the memory at the rated speed, or if it can't handle that it's scaling it back to the 1067MHz that came in your computer. You don't need to worry unless it starts telling you that you need to restart your computer all the time (kernel panic)
