I have been doing some research the past couple days when it comes to ram, and I would like to share some information that I obtain from various sources. I noticed that a lot of users are having problems with the REV A and REV B 15-inch Aluminum PowerBooks when it came to RAM. Many users are buying their RAM and finding out that it is not compatible with their machines.
The other day I was looking into buying some crucial ram and noticed they offered two chips with the same specs but one was specifically for the PowerBook. I gave them a call and asked the reasoning behind the two different chips that they offered, which seemed to have a $50 price difference. The model numbers were CT434058(PowerBook Specific) and CT12864X335. The tech stated that the PowerBook specific chip ran at a lower power, and was guaranteed to run on the current PowerBooks that Apple has to offer.
After hearing this I said great, but why is it that REV C and REV D PowerBooks seem to accept more types of RAM than the previous revisions? Could it possibly be that Apple fixed the issue that Crucial explained with the power consumption? That’s the question that I would like to find out. I contacted a local tech store that offers both types of RAM and does a large amount sales when it comes to computer products. Supposedly the same question was brought up a number of times by their staff. They stated that the cheaper RAM(NOT PowerBook Specific) offered by Crucial will work on the REV C and REV D.
My Question:
Has Apple addressed the issue with the Aluminum PowerBooks being selective about the RAM it will accept in the later revisions or is it just random luck that users are having?
