H-ig41-uatx Rev 1.1 Schematic |best|

Provides the operational voltage for the DDR3 memory subsystem. The schematic details a synchronous buck regulator or a linear low-dropout (LDO) regulator configuration generating this stable line from the main +5V or +3.3V rails. 3. +1.25V_VTT (FSB Termination Voltage)

What is your motherboard showing (e.g., completely dead, fans spin but no display, loop-restarting)? h-ig41-uatx rev 1.1 schematic

When tracing a "no display" issue, the schematic is used to check the PWM (Pulse Width Modulation) signals feeding the Northbridge. Unlike modern processors where the memory controller is inside the CPU, on the G41, the memory controller is inside the Northbridge. If the RAM voltages (VTT) are not correct according to the schematic, the board will not POST. Provides the operational voltage for the DDR3 memory
