Hi i have ms 6714 mother board how to know its 040 or 020

1) The Micro Star International MS-6714-020 motherboard uses an Intel 845GV motherboard chipset.

Underneath the Heatsink on the Northbridge chip is the part number Intel 82845GV.
On the Southbridge chip the part number is Intel 82801DB. (ICH4)


2) The MSI MS-6714-040 motherboard use an Intel 845GE motherboard chipset.

Underneath the aluminum ribbed Heatsink on the Northbridge chipset is the part number Intel 82845GE.
On the Southbridge chip the part number is Intel 82801DB. (ICH4)

List of Intel Chipsets, and specifically the one's for the Pentium 4's,

How to know the difference without knowing what part number is on the Northbridge chip?
Easy.

The Intel 845GE supports Integrated Graphics, and AGP (AGP 4X)

There is an AGP expansion slot on the motherboard for using an AGP graphics card.

The Intel 845GV supports Integrated Graphics only.

There is No AGP expansion slot.
Just the three white PCI expansion slots.
