TOPIC

    This article provides the memory specification and expansion capability for the iMac (Early 2001) computer.


DISCUSSION

    The iMac (Early 2001) has two RAM expansion slots. The slots accept standard PC-100 or PC-133, 168-pin DIMMs with the following specifications:

    • PC-100 or PC-133 Synchronous DRAM (SDRAM)
    • 3.3 volt, 8-byte, non-parity, 64-bit wide, 168-pin module
    • Maximum of 16 memory devices on the DIMM
    • Unbuffered; do not use registered or buffered Synchronous DRAM (SDRAM)
    • Maximum height of 50 mm

    Using PC-133 memory does not provide additional speed benefits over using PC-100 memory. Although the iMac (Early 2001) supports PC-133 DIMMs, the PC-133 RAM will operate at 100 MHz speeds.

    There are two DIMM slots accessible from the bottom of the computer. Use a coin to release the access panel and install the memory.

    The maximum DIMM size for each slot is 512 MB, for a total of 1 GB. The base memory configuration varies depending on the iMac model. The 400 MHz and 500 MHz models have 64 MB; the 600 MHz model has 128 MB installed.

    Video memory

    Depending on the iMac model, there is either 8 MB or 16 MB of soldered SDRAM dedicated for video. Although it's not upgradeable, iMac can display 24-bit color at its highest resolution. Check the Apple Store (http:/store.apple.com/) for further information.
