4.1.6 Power Rails
The main board supplies 12V, 5V, 3.3V, and 3.3V_stby power to the memory riser. The Memory
Riser has on-board regulators to generate 1.5V, 1.8V and 0.9V. The FBD AMB requires 1.5V,
the FBD AMB and DDR2 DRAM require 1.8V, and the DDR2 termination requires 0.9V. The
DIMM EEPROM and AMB SPD Bus require 3.3V. DIMM LEDs and control circuits require
3.3V_stby.
