| PC133 Works in the iMac G3 |
Posted by: 68kPlus on 2023-02-28 19:20:40
Yesterday I found a stray 512MB PC133 RAM stick, so I installed it in my iMac G3 and it worked first try.
EveryMac says they only support PC100 RAM, but I guess the iMac slows it down so it supports it.
Just thought I'd let you guys know as it might work for you too. |

Any half decent quality PC133 RAM I've found works fine in any SDRAM equipped Mac. |

In general, PC133 RAM is supposed to be backwards compatible with PC100 and PC66 as well. Our old iMac DV worked fine with two 512MB sticks of PC133 RAM, but my Blue&White G3 never properly recognized those same sticks at their full capacity.
I believe certain older memory controllers don’t fully recognize the more dense memory chips used in the 512MB RAM sticks.
These days, EveryMac is usually spot on with this stuff; I’ve yet to find a situation where it said something that turned out to be incorrect. You sure you were looking at the right iMac model? A lot of G3 iMacs look nearly identical, so it can be hard to tell the exact model sometimes. |

I generally buy PC133 for my PC100 and PC66 machines, I figure it will run cooler. |
