What RAM works with the Powerbook 12"?

I just wanted to know what versions besides PC 2700 RAM works in a Powerbook. PC 4200 are half the price of PC 2700 for some reason, so I was just wondering if I could get a gig for $66.

<sigh>

The 12" Powerbook uses DDR 333 MHz RAM (PC2700). The new (>Oct 19) 15" and 17" Powerbooks use DDR-2 533 MHz RAM (PC4200 or more clearly, PC2-4200)

The two types of RAM are incompatible - you cannot substitute one for the other. The fact that both start with "PC" is immaterial -- I wish the industry would just standardize on PC2700 vs DDR2-533 and there would be no confusion...

For good, Mac guaranteed memory, you are looking at about US$125-$139 for DDR PC2700 SODIMMs

DDR-2 533 SODIMMs are about US$89

Thanks

PC4200, unfortunately doesn't fit. After i ordered from 18004memory.com and got a PC4200 stick in by mistake, went to walmart to buy some precision screw drives, and then got the panel off, popped out the old 256stick then tried to put in the PC4200 stick in my 12" PB, i realized that not only was it not compatible, it didn't even fit in the RAM slot. Unfortunately probably out 15% for a restockin fee, even though the invoice says 100% Powerbook Certified, that may be the only thing that saves me that 15%, I also had to pay 148 for a 1GB stick of PC2700 as opposed to 91 for PC4200 with second day shipping to my door. I bought all this in stead of going through the hastle of selling my 12" PB and then financing the remainder for a MacBook Pro, no i'm just gonna up the RAM in my 12" and buy iLife '06 and an HD camcorder for my upcoming ski trip in February. Hope my misfortunate situation helped you out some...

I was looking for the same info about intel iMacs earlier, I found this on apple's site

the prices are astronomical, but it gives you the model details you need to head off elsewhere for a cheaper version.
