post #11551 of 19578
Can someone help me why cant i change to adaptive core. Voltage mode I'm overclocking base clock to 126.50 MHz x37 nb 35
It only works in override mode
When I oc the multi and not touch the base 100mhz it works
But not when I'm oc base clock

Let me know if you need certain information.

Here are the things that can affect whether your voltage changes.

1) C-States. If you have them all disabled I'm not sure your voltage will drop when you're idle. Enable all the C-States (including C6 and C7 if your PSU is compatible).
2) Windows power plan. If you're on a "Performance" plan your voltage will not drop. Go to a "Balanced" plan.

You might also want to make sure EIST is enabled so your clocks also drop.

Also, how are you checking voltage? HWInfo seems to work well.

Also, why do you want to run Adaptive? On Manual your voltages and clocks will drop too, and your voltage won't spike if you run an AVX instruction.

I know this differs per mobo but anyway..

1) You can have all C states disabled and use Adaptive - this allows 0.7v
2) You can use Performance plan and volts will drop. This doesn't effect volts. If you want, you can drop the min. processor to 5% which matches the Balanced plan but I keep it at 100% anyway (this is about the frequency.. not volts).

It's true that it's about frequency and not volts, but under full frequency (above stock 3.4/3.5GHz) the cores receive full voltage (as per the instruction: manual input V or offset V or adaptive V)..., unless otherwise implemented by the manufacturer. In my case, all i need for the voltage to drop (under adaptive) is EIST and balanced 'power plan' (or as you said, for high, drop the min state to 5%)
The 'c-states' only drop the voltage further but should not be required to drop the voltage 'at all'. I for one, also have a "cpu overclock fixed mode" setting in the bios, and if that is enabled, there will be no VID drop.

If your concern (iamkraine) is power saving, then you should not worry to much about this, since the difference between idle at full voltage and idle at 0.7V will be only 2-5 watts and further 2-4 watts if you have all 'c-states' on. The power drow from the mains increases with load (at a given freq and voltage)
You can check this yourself with a 'wattmeter', or a multimetter (with amp-metter clamp) using W = A × V (watt = amp × volt).

If the concern is over degradation, again, it will be insignificant at idle+full voltage versus idle+lower voltage. You need lots of amps (caused by load) for max degradation.
The idea is, for max degradation you need high amps (caused by heavy load) which increases with frequency (and obviously you also need higher voltage for higher freq in order not to crash) and all this also generates allot of heat.

degradation = high freq at heavy load + high voltage + heat
the lower any of the three, the less degradation will occur.

ex1: 4.2GHz@1.3V@80°C is less degrading than 4.6GHz@1.3V@80°C
ex2: 4.2GHz@1.2V@80°C is less degrading than 4.2GHz@1.3V@80°C (but the difference is not as big as in the previous example)
ex3: 4.6GHz@1.3V@70°C is less degrading than 4.6GHz@1.3V@90°C (this is pretty obvious)
ALL OF THE ABOVE AT LOAD

If we were to talk about killing the chip and not degradation, then it's as intel said: "voltage kills the chip not the heat"

Sure will not work ony my Asus Z87 Gryphon. Only adaptive drops voltage down. And of course EIST on, C-States on.

Interesting. What softare are you monitoring the voltage drop with?

Both my gold asus z87 boards will drop set to manual with all cstates enabled as long as I set the power plan in windows to balanced or power save. Performance will just lock it at max.

What I notice is the on my mpower with 4670k when I have all power saving on c1e on eist on and override voltage mode the core voltage drops. In
Idle but cpu vid doesn't on adia64 so I guessing that in override mode with all power saving etc on. the core voltage is already built up in the cpu itself and in load it will feed voltage in to the core but in adaptive mode there is no voltage feeding into the cpu first only when in load the voltage goes straight to the core instead of going to the cpu first so adaptive is still better if u have a stable system that's why in adia64 when you have it in override voltage mode and all power savings on the cpu core voltage will go down but not the cpu vid

CPU-Z, HWmonitor and used also XTU I think. It is known fact with Asus board from what I have seen.:-P And while not having ROG, TUF is hardly some crap. smile.gif

Thank you. So I can use manual mode instead of adaptive and get he same results just by enabling C-States?

Could it become a problem or increase degradation when the CPU is going up and down in voltages vs having a constant stable number of volts running through it?

Agreed. You can use Adaptive any time with any configuration. It's just most efficient (power-wise) when combined with C-States.

I'll have to retest with the CPU min. and max. settings in the power plan. I seem to remember that my Vcore wasn't dropping when I had the min. and max. set to 100% in a plan. I'll check it out tonight.
