Notes
    1. VRAM soldered on the logic board.
    2. Removable SIMM. No VRAM soldered on the logic board.
    3. You can install 512K VRAM SIMM, but only an additional 256K of VRAM is recognized.
    4. Uses DRAM instead of VRAM. The amount of DRAM is not expandable.
    5. The IIci and IIsi use the 1 MB of DRAM installed in the computer. On the IIci, this is the bank A.
    6. VRAM SIMMs in the Quadra 700, Quadra 900, and Quadra 950 must be installed in pairs of two SIMMs.
    7. Power Macintosh models use DRAM based video for the built-in video, they are only expandable with the VRAM Expansion Card installed. All SIMM slots must be filled on the VRAM expansion card. The Power Macintosh 6100/60 is not expandable. The AV card in the AV versions of the Power Macintosh computers have 2 MB of VRAM and are not expandable.
    8. The 7200, 7300, 7500, 7600, 8500, 8600, and 9500 use VRAM DIMMs instead of the customary SIMMS in older Macintosh computers.
    9. "On Board" in context of the PCI-based Power Macintosh computers indicates that 1 or more VRAM slots are taken up with DIMMS when they leave the factory: thus, the 7200 has 3 available VRAM slots, while the 7300, 7500, 7600, 8500, and 8600 each have two available to reach the 4 MB VRAM maximum.
    10. All DIMMs for these computers are manufactured with identical specs; so this is not a relevant statistic.
    11. For the Power Macintosh 9500 computers with the onboard video you can purchase a separate 2 MB Upgrade Kit that installs onto the card itself.
    12. Since Power Macintosh 9500 computers without video cards require third-party PCI video support, the VRAM requirements and capabilities vary by manufacturers.
    13. The Power Macintosh 4400 series includes 2 MB of EDO memory for video memory, but it supports configurations up to 2 MB 5 V EDO memory or 1, 2, or 4 MB of 3.3 V SDRAM or 3.3 V SGRAM.
    14. The Power Macintosh 5500 and 6500 series computers include 2 MB of SGRAM, which is NOT expandable.
    15. The video card included with the Power Macintosh 9600 series computers includes 4 MB of video memory, which is not expandable.
    16. The VRAM banks must be populated in order. If there is a VRAM upgrade, the SIMM slots should be populated from the back of the CPU to the front.
