Added memory not recognized!

[Hammer45]

I just changed out my 256MB chip and installed a 512MB memory chip. The problem is, my iBook doesn't seem to know it! The System Profiler and Top both report the same 384MB total it had before. How do I get the iBook to see the additional memory?

it should just see the right memory, unless the module is of the wrong type or possible wrong size. Maybe it's really a 256mb module and not a 128, only way to really check would be to put it in another notebook =/

It seems like that you have a bad memory module. What you have to do is to get a refund of it. I have a 512 MB memory module to sell. It worked flawlessly with my previous ibook. Now it is working in my new powerbook. As far as I know PC133 sodimm memory works in ibook, powerbook and new iMac memory slot. Test your memory using one of them. Good luck.

There is an interesting article from Apple info.

What version of the iBook do you have? is it the Clamshell or the newer, white version?

I have had a dual USB ibook 500MHz. But now I have a powerbook 800MHz.

Aha! The AppleCare document explains a problem I had - I bought a 256Mb PC100 SO DIMM for my PBG3 and it was showing up as a 128. I had to pay more to get a Kingston 66MHz version for it to work right. Not very well thought out those firmware updates!
