Industrial ATX motherboard with legacy ISA slots

The G41_3ISA is an ATX form-factor board built around the Intel G41 plus 82801GB chipset. It targets industrial PCs and servers that still rely on ISA expansion cards while also accepting Socket LGA775 Core 2 Duo or Core 2 Quad processors.

Verify CPU cooler clearance and DDR3 memory stock

Confirm that your LGA775 processor matches the supported FSB range of 533, 800, 1066 or 1333 MHz. The board provides two DDR3 DIMM slots limited to 8 GB total, so source compatible modules before assembly.

Fits standard ATX cases

Measuring 305 by 244 mm, it mounts in ordinary ATX enclosures. Three ISA slots and four PCI slots handle legacy I/O cards, while a single PCIe x16 slot, four SATA ports, one mSATA connector, IDE and CF interfaces cover storage and newer add-in cards.

Questions about this item

Does the G41_3ISA board ship with a CPU, memory modules or an I/O shield, or must they be purchased separately?

The board is supplied as a bare mainboard; a Socket LGA775 processor, DDR3 DIMMs and an I/O shield are not included and must be sourced separately.

Which expansion-slot layout does the G41_3ISA provide for legacy industrial cards?

It offers three ISA slots, four PCI slots and one PCIe x16 slot, giving the broadest legacy connectivity in this series.

What does the onboard GMA4500 graphics and dual Realtek RTL8111E LAN mean for a headless industrial server?

The integrated GMA4500 handles basic VGA output for initial setup, while the two RTL8111E controllers provide redundant gigabit Ethernet without adding a discrete NIC.
