AIMB-762 Rev. A1 19C2076203 - Advantech LGA775 Intel 945G DDR2 Dual Gigabit LAN ATX Industrial Motherboard

This industrial ATX motherboard is built for legacy control systems, embedded workstations, machine automation platforms, and industrial PC repairs that require the AIMB-762 layout. It uses the Intel 945G + ICH7R chipset, supports LGA775 Pentium D, Pentium 4, and Celeron D processors, and provides a versatile expansion layout with PCIe x16, PCIe x4, and five PCI slots. With dual Gigabit LAN, onboard VGA, DDR2 memory support, four SATA II ports, and legacy IDE connectivity, it is a strong replacement option for older industrial systems that still rely on proven I/O and expansion flexibility.

⚙️ Fit Notes

• This board uses the LGA775 platform and requires a separate compatible CPU, heatsink, cooling solution, and DDR2 memory.
• It is designed for standard ATX mounting and requires both a 24-pin ATX main power connector and a 4-pin ATX12V CPU power connector.
• For best results, match the replacement board by the AIMB-762 model family, PCB revision, rear I/O layout, slot arrangement, and onboard connector locations.
• The dual-LAN layout shown here aligns with the AIMB-762G2 family configuration.
• This platform does not support ECC memory.
• Systems with 4GB installed may report less usable memory depending on the operating system and shared graphics allocation.
• Please confirm CPU support, BIOS compatibility, chassis clearance, and required legacy I/O before ordering.
