    Default What is the CPU vcore supposed to be - P4 650

    I have a MSI P6N SLI-FI board and a P4 650 CPU installed. The BIOS shows a default vcore of 1.23. I also have a system with a Asus P5ND2-SLI and a P4 630 installed. The default vcore for it is 1.39.

    Whenever I try to raise the vcore of the MSI system to 1.36 - 1.39, it hangs at POST during morning start-up after having been off overnight. It won't load. BIOS won't even display.

    My question is: is it normal for the vcore to be different on different boards? I would figure a particular CPU would create a default vcore value consistent through all brands and models of boards.

    Thanks

    According to Intel for your CPU Vcore can be between:

    1.25V-1.388V

    So both vendor took different directions but both are within the limits.

    Strange how this motherboard operates. Anything very slightly different from default causes the system to either freeze before POST with memory or CPU hangs or crash in WindowsXP under certain programs. The default memory voltage is 2.0 but the system runs kind of sluggish and has the tendancy to crash if ceratin programs are run at the same time. A memory voltage of 1.8 causes system crashes. A memory voltage of 1.9 causes boot-up hangs before POST and system crashes when OS finally loads.

    A memory voltage of 2.2, 2.1 causes system crashes. A vcore voltage greater than 1.26 causes various problems.

    This MSI board is the pits. It is sold as a great over-clocking board but any slight deviance from default values causes all manner of problems. The biggest problem is pre-POST hangs.

    I should'a bought a EVGA board. That old American V8 juice commercial comes to mind..."I could'a had a V8". I wish I'd have bought something different. This has to be the worst board I've ever experienced.

    Sorry to read that and thanks for sharing with us. I remember reading good reviews about that one. I prefer Asus and Gigabyte boards , didn't have much problem with either brand.
