Meanwhile I'm trying to find a way to remove the hard lock on CPU and RAM frequencies (extreme CPUs can't be overclocked, RAM is locked at 1333 MHz) :)<p>Looks like it can be done through Management Engine, which has access to everything apparently.<p>Only success so far is unlocking BCLK, but the overclock is small and unstable that way.<p>Another roadblock was the read only lock, which can fortunately be bypassed on POST on xx67/77 chipsets.
This is nice, but it just allows you to replace some of the the Management Engine code. What we need to know in detail is what it's doing. There's probably a backdoor in there that hasn't been discovered yet.
