A few possibilities:
MSI P4MAM-V (MS-6787 v2.1)
Manual states vcore is adjustable (and screenshots shows a low vcore). Note: P4MAM2-V doed not have adjustable vcore anymore
MSI 845GEM/GVM (MS-6714 v5.x)
Manual shows a screenshots with "CPU Vcore adjust", but no mention in the description.
Could anyone confirm and state the exact model + revision of the board they know?
Are those P4 MicroATX MSI motherboard undervoltable?
