CPU And Northbridge GTL Default Settings
The CPU GTL chart can be read as follows: All related data is contained in the same row read left to right. Column #1 is the VTT voltage that is selected in the BIOS. Column #2 is the measured actual voltage for the corresponding selection in the BIOS. Column #3 is the GTL values that the board is defaulting to. These are the values that would need to be manually entered to duplicate the GTL voltage selection that the board is making. Column #4 is the measured default voltages for the GTL circuit(s) for the corresponding VTT selection in the BIOS. Column #5 is the percentage of VTT voltage that the GTL voltage is set to. This has been computed from the measured values of Columns 2 and 3. Column #6 is the required GTL voltages that are needed to equal 67% of the VTT voltage. Column #7 contains the GTL values that would need to be input by the user to bring GTL voltages to 67% of the VTT voltage.
