All,
I have the 1Ghz 17" iMac (Feb 2003 model). Apple says that this iMac must use PC2100 SO-DIMMs in the user slot.
The iMacs released on 9/8/2003 can use PC2700.
So, I went to OWC's site and ordered:
512MB PC2100 DDR 266MHz 200 Pin Low-Profile 1.25" BGA Memory Upgrade for Apple iMac G4/1GHz 17" model, all PowerBook G4 12" Models, all iBook G4 Models. New, Lifetime Advance Replacement Warranty. (OWC2100DDRSO512)
I got the part yesterday and while the front has a sticker that says OWC2100DDRSO512, the back of the chip has 2 stickers that say this is PC2700. I put the chip in and the iMac did boot up fine and seems to be working fine. System Profiler shows this is PC2700 RAM.
So, is this OK? Is this chip just dropping down in speed? Can this lead to any problems in the future? Will my system be stable with this RAM?
I'm going to call OWC today and see what the deal is.
