Hmm but i ran an X23800 at 3GHz on this mobo. That is only possible with an 300MHz ref HT. I think bytes 11 and 12 play the main role for the ref HT.

But the VIDs are different to voltages - are you saying SVID can allow finer voltage control?
If so, then yup that's true.
There is a PCI register showing whether this SVI SMbus interface exists or not. If Bit 3 is set on your system the interface is unused.
It turned out i was wrong with the chip at 0x4c. This is the thermal interface. Four bytes change their values enormous if I build the kernel and sligthly when in idle.
