Looks like it can be done through Management Engine, which has access to everything apparently.
Only success so far is unlocking BCLK, but the overclock is small and unstable that way.
Another roadblock was the read only lock, which can fortunately be bypassed on POST on xx67/77 chipsets.
You mean non-extreme?
> unlocking BCLK, but the overclock is small and unstable that way
On desktop Skylake, BCLK can get you to anywhere you want (I run an i5-6400 at 4.5GHz daily, over 4.7 for benchmarks). You're talking about laptops, right?
And BCLK allows for a 5MHz overclock, which is not much, anything more and the system crashes. Which is really strange, may have something to do with PCIE as Dogma said.
I just want to get everything out of my extreme processor and RAM.
Intel's HEDT platform supports proper CPU strap overclocking withou adverse effects, but even then it's usually not recommended unless you are doing extreme OC and that's liquid nitro :)
I thought Intel shut this down with microcode updates.
I feel like there would be legal problems though...
When we were rooting Android devices we sat on a lot of exploits that we believed we could use to give end-users freedom. There were a handful that were bad enough to warrant disclosure [1], but we still offered them as ways for users to control their own devices with a few layers of obfuscation on top.

I often think whether one should really help people who decide to buy locked-down Android devices.
Sure, they could release a new version with the bug fixed, but the attacker doesn't have to use the new version, they can deliberately use the old flawed version in their modified version of the bios.
