Anyone knows where the clock generator for the bclck on the mobo is located?

I thought about something regading the 222mhz bclck limit.

What if this limit is not due to the qpi clock but rather caused by the bclck generator itself?

This would also explain why all boards can clock near that limit, some higher, some lower.

Maybe a voltmod for the clock generator would harness higher clocks?

Or it also could be a complete brainfart from my side.
