Since all PowerBook G4s are slightly different, you should check EveryMac’s PowerBook RAM Guide to determine what sort of RAM your PowerBook needs. So, the more RAM you have in your system, the faster it should be! That’s because the Mac won’t need to swap information, and that will make your system run better. Your system will slow down, because the hard drive is much, much slower than RAM (RAM is like 100,000 times faster than a hard drive). If that happens, you’re in for some serious waiting (not to mention hard drive-grinding noises). You’ll be able to run more applications simultaneously, and your Mac won’t slow down after you’ve had it on for extended periods of time.īut is RAM really important? Why do people need it? When your Mac uses all the available RAM, it starts to put the information that was supposed to be stored in the RAM directly onto your hard disk drive. The more RAM you have installed in your Mac, the faster your Mac will run. Applications are usually loaded into your RAM, as are files you are working on. Your Mac uses RAM to store information that needs to be accessed quickly and easily. RAM is a little like your hard disk drive, only there are no moving parts, and RAM is faster - a lot faster. RAM, or “Random Access Memory,” is a type of data storage used by your computer. This inexpensive upgrade can be performed by anyone in a matter of minutes, and after you’re finished, your Mac will run like new! Installing RAM into your PowerBook G4 is the easiest way to breathe new life into your aging portable.
