1Officially, this model supports a maximum of 256 MB of RAM. However, third-parties have discovered that it actually can support 512 MB of RAM with four 128 MB memory modules
2The Power Macintosh 7200 and WS 7250 logic boards have four DRAM DIMM slots, each with a 64-bit data bus. You can increase the computer’s DRAM to a total of 256 MB using 5-volt, 64-bit-wide, 168-pin fast-paged mode, 70 ns DIMMs.
3These computers do not have any main memory soldered to the logic board. At least one DRAM DIMM must be present for the computer to operate. DRAM DIMMs can be installed individually or in pairs. These computers support linear memory only; therefore, no memory gains are seen when two DIMMs of the same size are installed (that is, memory interleaving is not supported on the Power Macintosh 7200 Series/WS 7250 computers).
4Apple Technical Information Library (TIL) article Power Macintosh Computers: Using FPM, EDO, SDRAM & SGRAM notes that only the Power Mac 5500, 6500, and some variants of the Performa 6400 can fully benefit from the improved read cycles afforded by 5v EDO. In order for these Macs to benefit from EDO, however, all memory installed must be EDO. In the event FPM and EDO memory are mixed in these machines, the memory controller will address the DIMMs in Fast Paged Mode (FPM). Interestingly, MacGurus has noted far better compatibility in these Alchemy variants using 5v EDO rather than 5v FPM, and strongly recommends its use. All other Apple Power Macintosh, with the exception of the Power Mac 7200, can utilize EDO memory, but reap no performance benefit from doing so. Apple technical documents emphasize that utilizing EDO memory in the Power Mac 7200 may damage the motherboard, and may not be covered under Apple Computer's limited hardware warranty.
