is ram backwards compatible? i thought i read somewhere that it was. for example, i have a stick of PC133 in my old ibook. my new one is PC 2100. would i be able to use the PC 133 ram in my new ibook’s extra slot? ---

i don’t see anything detrimental happening from trying it. i just don’t want to go to the trouble of taking two laptops apart if it won’t work. further research is saying that i only have one slot anyway. so i’m thinking i won’t even bother. i thought i had two. ---

Your computer will clock the ram down to the slower speed. ---

No, PC133 (168-pin) won’t physically fit in a slot using PC2100 (184-pin) PC66/PC100/PC133 are “usually” interchangable, depending on the motherboard. ---
