    So I bought an iMac G4 a few weeks ago and decided to upgrade the ram in it. Since desktop memory is a bit less expensive than laptop memory I decided to upgrade the internal ram directly on the motherboard. I took out the iMac's original 256mb stick and put in the new 512mb stick, its PNY if it makes nay difference and yes its the right sort: PC133. So the problem is that when I started it up again about this mac and the system profiler still say my iMac has 256mb of ram. Is this just because the internal ram isn't meant to be upgraded so it doesn't change, or is there something wrong with the ram I installed? And I'm not sure if I'm just being paranoid, but it feels like its a bit slower than before, even after reinstalling Tiger.
    Anyone know anything about this?

    Specs: 700mhz, 40gb hard drive, DVD drive, 15" screen, supposed to be 512mb ram

    Sounds like you bought a high density stick. PPC Macs only take low density sticks of ram. If you put in a high density stick, it'll only see half of it.

    Also, you don't have to take out the 256 MB stick. You can just leave that in. You should then see 512 in the profiler.
