    Default GA-EP45-Extreme

    Hi !!!
    I've a Gigabyte EP45-extreme.
    l'm actually at 501x8.5 and stable.
    But when i want put 506x8.5 => always reboot when OCCT start since 5 min.
    Do you know why.

    Can you please list your full specs, and what setting you are using for 501

    in CPU-Z, Vcore in idle is 1.408V and load is 1.378V (???) but in bios Vcore is 1.450V.

    Looking at your CPU and PCIe clock drive settings, you may be running using fail safe defaults. This may have happened when updating the BIOS and neglecting to load optimized defaults after the flash.

    Write down your current settings as they are now and load optimized defaults. save, exit then re-enter the BIOS and re-set your stable config. Don't reload it with a saved profile, as that will restore failsafe values for clock drive etc.

    All the settings you have on Normal would be better on auto. I'm not sure if setting Normal allows them to scale as they should, but auto certainly does. The board will not over volt those settings if set to auto.

    As a start point, try the 2.00D memory multi. this may alow for stability at a higher FSB. Also set a manual Static tRead value. You may be ok with this set to 10 but try it at 12 for now and lower one step at a time when you're stable at your new FSB speed. An additional bump or two (up to 1.61V) of PLL may be beneficial.

    What you see for Vcore is normal. The difference between BIOS setting and idle in CPU-Z is called Vdrop and the difference between idle and load is called Vdroop. This is part of Intel specs regarding VRM's and CPU power circuitry and is fine. You can by pass the Vdroop bit by enabling LLC. This may even allow you to use a lower setting for Vcore and maintain stability.
