The Foxconn HIG41UATX (Revision 1.1) is a legacy motherboard commonly found in OEM desktop systems, particularly older Lenovo ThinkCentre models. Built on the Intel G41 Express chipset, this board pairs with the ICH7 Southbridge to support Intel Core 2 Quad, Core 2 Duo, Pentium, and Celeron processors utilizing the LGA775 socket.
Supports two slots of DDR3 RAM, a major upgrade over the DDR2 found on older G31/G41 boards.

The verification process consisted of the following checks:
Before diagnosing component-level circuitry, understanding the hard boundaries of the board's traces and layout defines what the electrical lines are designed to handle.

Here is a table of discrepancies found between unverified online schematics and the actual HIG41UATX REV 11 board: The verification process consisted of the following checks:
: This enters through the 24-pin ATX connector. Check for 5V at the linear regulator converting this to +3.3V_ALW (Always) to feed the Super I/O chip and the Southbridge.
Always measure before soldering. Using values from a fake schematic can burn the ICH7 or memory slots.
