333MHz iMac & 256MB Stick O' RAM
My friend has a 15" flat panel iMac that she just had all the original RAM replaced. It had a 256MB SODIMM and a 256MB SDRAM, which she just replaced both with 512MB sticks. I put the SODIMM in to an old 333MHz iMac yesterday but it only appears to onlt be 128MB. It has the latest firmware and OS X. Why isn't working? Thanks.
