    Default P55-UD3R general settings question in bios.

    I was reading the forums over at gskill, about the ram I have. And they have a guide to set the ram up. My question is, is there a reason they have certain stuff in the bios recommended to be disabled?

    Here is what they posted.

    F3-16000CL9D-4GBTD + Gigabyte P55-UD3R BIOS settings <hr style="color: rgb(255, 255, 255); background-color: rgb(255, 255, 255);" size="1"> <!-- / icon and title --> <!-- message --> These settings will work for other DDR3-2000 memory packages as well.

    Save and exit, everything should run smoothly after that.

    What benefit is having stuff like CPU Clock Ratio from 21 to 16, Turbo Boost, EIST, Virtualization, etc disabled?

    Ok. I overclock, and have those all enabled. Reason they recommend disabling them for stability reasons? Not sure if I should have them enabled or disabled.
