    I recently bought 8GB of RAM to replace the 4GB of RAM for my mac, and it is having some issues.

    Here is exactly what I bought.

    This should work in my mac, but when I boot, my mac tells me to shut my computer down and restart, and I am only able to boot half the time. I also have a Windows partition, and I am able to boot into that, but the screen scrambles, or it seems like parts of it in horizontal lines go all over the screen.

    When I am able to boot, the mac does see all 8GB of RAM and says the status is ok.

    I've tried rebooting, the PRAM reset, and cmd+v boot. any help would be appreciated.
