The Power Mac and Performa 6200-series have two (2) 72-pin slots and a 32-bit data path. This computer requires standard 80ns non-parity SIMMs or faster, in either 2k or 4k refresh, and typically ships with either an 8MB or 16MB SIMM in one of the SIMM slots.As there is no DRAM soldered to the logic board, the 6200-series requires that at least one SIMM be installed for the computer to boot. SIMMs may be installed in any slot, in any order, and in any size, with supported memory configurations including 8MB, 12MB, 16MB, 20MB, 24MB, 32MB, 36MB, 40MB, 48MB and 64MB. Since this logic board does not have a 64-bit data path, there is no need to install SIMMs in pairs, as in earlier generations of Power Macintosh. The maximum amount of usable memory in the 6200-series is 64MB, in the form of two (2) 32MB SIMMs.
This motherboard does not support memory interleaving.
As is the case with the Power Mac 5215, L2 cache comes preinstalled in the form of a proprietary Apple SIMM that also hosts ROM ICs on its reverse side. Article Mac Performa 5200 6200 FAQ (TECHINFO-0018928) from Apple's Technical Information Library (TIL) confirms the unavailability of third-party L2 cache SIMMs for this motherboard in general, and the unavailability of appropriate Apple-manufactured L2 cache SIMMs in capacities larger than 256k. Replacement pieces, in the event of defect, must be ordered through Apple Authorized Service Providers.
Specifications Logic Board RAM None. Supported SIMMs 8MB, 16MB, 32MB. Number SIMM Slots Two (2). Supported VRAM 1MB non-upgradeable, soldered DRAM frame buffer. Number VRAM Slots None. L2 Cache Supported 256k on proprietary Apple SIMM module. SIMM Type 72-pin, FPM 32-bit, 2k or 4k refresh, 80ns or faster.

As noted, the 6200 utilizes a 1MB DRAM video frame buffer, and consequently has no VRAM slots on the logic board. No expansion beyond the 1MB video frame buffer soldered on the logic board is feasible. It is possible, however, to install video cards in the LC-style PDS slot of these computers, affording access to higher video resolutions, and permitting use of larger monitors in addition to their built-in video displays.
