How on earth does that equal a 0.2-0.3 voltage increase?

My P4 went from 3.0Ghz to 3.26 (ish) without any voltage increment whatsoever.

I'd quit if I were you though.. you're already over the max voltage..
Or try to find a way to turn off that auto function of Asus that makes your voltage increase..

mm..
im scared myself too!!
ill search again..
thanks guys..

maybe it is set on 'enable'.. im not sure..

If you are referring to "CPU Vcore Over Voltage Control" I think ( as I have already said ) that this option, when enabled, allows the mobo to protect your cpu from inadvertently getting more voltage then it should (in case of a psu power fluctuation for example).
It does not appear to allow you to manually set the desired CPU voltage nor does it appear to automatically set the voltage.
If only Asus was a bit more descriptive when writing those motherboard manual.

so, with the "CPU Vcore Over Voltage Control", i should enable or disable?
it is now enable and still i get 1.568V even after i set it back to 3.2GHz.. (same as 3.44GHz) help please..

Is it always stagnant at 1.568V ?
Before you disable it... try running Prime95 to make your cpu work under load and then, while Prime95 is running, try monitoring your VCore in Cpu-z.
Does it fluctuate ?
I'm afraid your psu might be the culprit as it is the main source of voltage distribution within the system. Not to forget that software based readings are not always as accurate as many people tend to think.

Well you got to stick to the same program (speedfan for example) to check both voltages (on the cpu core) when idle and when under 100% load.

1) run speedfan.
2) write down the values of vcore and +12V while the cpu is idle.
3) run Prime95 and monitor/write down the variations of vcore and +12V for a minute or so.
4) restart the machine and disable "CPU Vcore Over Voltage Control" from the bios.
5) run speedfan.
6) write down the values of vcore and +12V while the cpu is idle.
7) run Prime95 and monitor/write down the variations of vcore and +12V for a minute or so.
8) post back both all results as shown below.

CPU Over Voltage Control enabled
--------------------------------
vcore idle:
vcore load:
+12v idle:
+12V load:

CPU Over Voltage Control disabled
----------------------------
vcore idle:
vcore load:
+12v idle:
+12V load:

results:

CPU Over Voltage Control enabled
--------------------------------
vcore idle: 1.44V
vcore load: 1.38V
+12v idle: 12.25V
+12V load: 12.14V


CPU Over Voltage Control disabled

well.. i did the test but theres not much difference to me..
anyways, thanks..

errmm..
i wanna ask another question.. its about heat..
resently i take out the HSF and put it back..
i re-apply the thermal paste..
my processor temp is quite high (around 41C-45C at idle)..

my question is: if the heat sink is hot (i touch it), is this means i put the HSF the right way?
if its right, why its still hot? =(
