2-3 System Memory Configuration

The P55-VP 2 supports different type of settings for the system memory. The
following figures and table provides all possible memory combinations. (Please refer
to Appendix C: Memory Configuration Table for the details).
DIMM
NOTE : 1. P55-VP 2 supports both Fast Page DRAM and EDO DRAM SIMMs, but
they cannot be used in the same memory bank.
2. The KEY ZOOM of the DIMM socket is 3.3V / Unbuffered.
