I am going to buy a 512MB RAM chip for my G4 500 AGP. I think it uses PC 100 RAM, but wont PC 133 RAM work in it? I am buying it from best buy for 100 dollars...it is the cheapest place to get RAM.
My G4 400 pumped full of PC 133 doesn't seem to know that...Originally posted by germanknee
i'm not sure that your reasoning is correct, although it sounds good. i think a faster bus can handle slower ram, but a slower bus can't handle faster ram.

667 tibooks use pc133 ram...right? so wheres the cheapes to buy one right now?

Sure does.Originally posted by Rower_CPU
Beej is correct. The bus dictates the speed the RAM runs at. If you're on a 100 MHz bus, the RAM will run at 100, hence PC-100 is recommended. PC-133 runs fine in 100MHz systems.
PC-100 will not run in a 133 MHZ system. This becomes crucial for people who are trying to overclock their systems. People who won't/can't change their clock multiplier will increase their front side bus for more speed. If you have crappy/slow RAM you won't get far. This is why people recommend CL2 RAM for better performance, and why people sell PC-150 RAM to overclockers who will be pushing their FSBs past 133.
Make sense?

I have a TiBook g4 550 Mhz with 256 MB built-in.. i am planning to upgrade to 768 by getting a 512MB from memorytogo..which one should i choose

I understud that hi-profile is Apple certify memory that fill Apple standards. Low profile may not meet the standards it can give some troubles when you upgrade the sys rom of your machine. I know that for a recently experience.
About two weeks ago I went to a friend of mine that has an Apple store. He asked me to brought my Pismo for an experiment. He had one low profile memory that didn't work with his pismo but later on it works with mine.
He had a 512MB ram that really was 2 256MB chips soldered togather very tight. What happen, I had sys 9 only and my rom was the old one, my friend had OSX that uses a new rom that sure reconizes more aspects of the memory (I'm sure to guaranted stability). So that is what I know about that and from 2 different sources.

Come to think of it, I'm pretty sure the RAM that came with my old G4 (100 MHz bus) actually came from Apple with PC 133 in it.
I think. Can anyone tell me if I'm crazy?
