Hi,

I've been using an MSI Z68A-GD55 motherboard along with an i5 2500K CPU for a long time.

Today, I just wanted to check my BIOS settings for a possible overclock of my CPU. I've looked for how the OC settings are applied from various websites, forums, etc. and it wasn't complicated at all.

The problem I have is, the second option in the Overclock menu in my BIOS (Adjust CPU Ratio) is disabled. It is set as Auto and it cannot be modified.

Do you have any idea what causes that setting to be disabled?

Thanks.

Use +/- keys of numpad to alter these settings.

Hi,

That worked, thank you very much. I've been looking for this information and it is not even documented in the user's manual. How is that even possible?

I have another question: Is it possible to apply different voltage level for each RAM slot? That is to say, is it possible to use RAMs needing 1.5V and 1.65V together, without any handicap?

Best.

No, that is not possible. You can only apply one ram voltage. You would need to use 1.65v for all if one stick would need 1.65v. I would not suggest to mix memory at all though.
