Although the processor is soldered in this model, third-parties cleverly learned how to use the L2 cache slot to bypass this limitation. As a result, a variety of third-party processor upgrades and accelerators were available.

  1. Officially this model supports 96 MB of RAM, but third-parties discovered that only the first slot is limited to a 32 MB single-bank memory module. The second and third slots can accommodate 64 MB memory modules for an actual total of 160 MB of RAM.
  2. It should be noted that the 4400 does not require DIMMs to be installed in pairs, as the PSX memory controller does not support memory interleaving. But Apple technical documents are emphatic in recommending a 1.100 inch height for 4400 DIMMs, in accordance with the shortest form factor permitted in the JEDEC MO-161 specification. Due to the internal organization of this computer, taller DIMMs will be forced down into the DIMM sockets with excessive force, with undesirable consequences.
  3. The Power Mac 4400 supports an optional 256k L2 cache DIMM with integrated cache controller. Apple technical documents intimate that Apple does not support the development of third-party L2 cache for this computer, despite the fact that the 160-pin cache expansion slot is identical to that found on Power Mac 5400 and Performa 6400 Alchemy motherboards.
  4. With a single 120-pin video DIMM connector internally (Burndy Corporation ELF120GSC- 3Z50), the 4400 series supports up to 4MB VRAM using either 3.3v SDRAM, or 3.3v SGRAM, in sizes of 1MB, 2MB, or 4MB. A single EDO 5v VRAM DIMM can also be utilized, but Apple technical documents note that the maximum usable size for an EDO VRAM DIMM is 2MB, as EDO DIMMs larger than 2MBs afford no additional performance due to the limited bandwidth characteristic of such modules. With a 4MB SGRAM or SDRAM DIMM, the 4400 can generate 32-bit color at resolutions up to 1280 x 1024.
