I updated my system's BIOS from a05 to a06 last night and am now unable to edit many CPU properties.

In particular, I'm now unable to modify any CPU multipliers.

I do not have a "K" processor, but it should be theoretically possible to overclock my i7 3820 to 4.3GHz by adjusting CPU multipliers on each core.

I am able to modify the CPU gear ratio (base clock) setting. Pushing this up a notch to 1.25 instead of 1 resulted in a machine that wouldn't post (all fixed now).

- Is it at all possible to overclock an i7-3820 via the a06 BIOS?

- Is anyone able to offer up any solutions as to how I can perform an overclock via the a06 BIOS?

TL;DR: I'm unable to overclock or alter most of the settings for my i7 3820 using the a06 BIOS on my Aurora R4. Is overclocking in this way now disabled on these machines, or am I doing it wrong?
