Hey.
I was thinking of getting a 1gb peice of ram for my iBook, which already has a 512 peice. My mom has a 17" PowerBook... which could use the extra ram... could I put my old 512mb peice in the PowerBook even though it requires 2700 instead of 2100? or am I just dreaming?

Thanks,
Wes
 
I think it MIGHT work. Don't know if the PB are backwards compatible with 2100. I know the iBooks are "forward compatible" with 2700 ram. I don't think it would hurt to try, but get another opinion before you do. I know on old PB Tibooks that the later versions were NOT backward compatible with pc100 ram (could only recognize pc133 ram) while the earlier Tibooks could take either pc100 or pc133 memory.

Probably not.

It depends what the 512 piece of memory ACTUALLY is, and which 17" Powerbook it is. What are the numbers on the sticker on the 512 Mb RAM module?

But if it is a PC2100 and the AlBook reuqires PC2700, it will be no-go.

I dont know what the sticker says.... its still in my iBook. But system profile says:

DIMM1/J31:

Size: 512 MB
Type: DDR SDRAM
Speed: PC2700U-25330


This might just be what the iBook thinks the ram is. I can open it up later to find out... but not right now.
 
I don't think it will hurt to try, and I think it is recognizing 2700 ram. On my iBook, I purposely bought 2700 ram for it that was backward compatible so that I could re use the ram for faster machines in the future -- and the iBook recognizes it on my computer as 2700 ram. So you've also probably got 2700 ram. Like I said, I don't think it would HURT the PB to try, especially if you've got another stick in it already. But someone should confirm this. I'm 99.9 percent sure you've got the right ram.

Looks to me like the same kind my 17" uses. :D
