I this link i found:

Quote
  • Current ASUS Bios 1002 and before if you change the default VID value, the Pstate0 (P0) will not work and will go to P1. This may change with a future bios or on other motherboards
  • To change CPU core voltage - use + or - offset values so you are not stuck with 1.35v or 1.1875v on a 1700

That why i can't make it work, i have to change the VID because i don't have (or i didn't found) LCC or offset values Cry

I'm thinking LLC _and_ Pstate OCing is a no go. ie: set Pstate value you definitely do not want LLC adding v's to the Pstate you set.

It's either Pstate or multiplier OC'ing And neither shall the two meet.

Frequency is locked at 3,8 GHz, but Vcore is only 0.6V at IDLE. can that be true?

You are looking the motherboard sensor, who is not very relevent if you want know the CPU voltage

CPU has his own sensor and if you want know the the voltage of the CPU, just watch the good line:



So no you don't have 3.8Ghz with 0.6V, even in idle the minimum voltage is still 1.294V

hehehehe No.

Notice that's the Minimum. Probably at boot up before Windows Power Plan kicks in.

no, not at boot. so I have to rely on the CPU sensor that tells me 1.3V.
then I guess voltage or frequency decrease is not possible when using multiplier OC on the pro4 unfortunately :(

will there be an updated BIOS/driver that lets us downclock when IDLE?
