PC100 RAM question

in Current Mac Hardware edited January 2014
I own a PowerMac G4 500 "Sawtooth" (AGP). I currently have 256 MBs. I need to max my memory. The Apple System Profiler states that my PowerMac has four PC100 3.3V 168-pin SDRAM slots available. MacTracker states that my Mac can max at 1.5 MBs under OS 9.2 and 2 MBs under OSX. My question is, how is this possible and does this mean I should purchase four 512k units? Also, what is an ECC registered memory? Is it any better than a non-registered or a non-ECC unit?

    It doesn't matter they are 133 sticks. Your computer's bus just won't use the last 33MHz and they cost the same as 100 MHz sticks.

    ECC stands for error check and correction. It's used mostly in servers and workstations.

    Don't buy ECC memory BTW. It won't work in you PowerMac.

    Actually it could kill something if you tried to use ECC RAM.

    Just go buy some regular PC-100 or PC-133 SDRAM sticks. And you need 4x512 MB (not kb) to have a total of 2GB (not mb).
