Memory Installations
The following table shows several possible memory combinations. The P5VX-Be system board supports from 4-128MB. Memory can be installed in a single DIMM or in pairs of 72-pin SIMMs. All 168-pin DIMM modules must use unbuffered 3.3 volt RAM and supports up to a single 32MB EDO or SDRAM. All EDO modules should be the same access speed, parity / non-parity, and configuration (single-sided, double sided, etc.) within the banks.
