Help with offset Voltage (ASUS P8P67 Pro)

post #1 of 12
Thread Starter 
I want to run at 1.36vcore when the CPU jumps to 4.7Ghz. I don't know what value to enter into the offset voltage field.
Right now i've used manual voltage but i don't like the high voltage on system idle.
Please help! If you need any more info, let me know.
Thank you in advanced for the time and help.

It all depends from your LLC level
+.065 (medium)
Bios settings for medium offset ! (Click to show)

you can also try ;
Phase and Duty @ Extreme but i don't think you have to

My LLC is "Very High" and Duty and Phase is set to Extreme.
So if i set the offset to +.055, will that give me around 1.36 on load for the Vcore. I am confused. Thank you for the help so far.

then you set that +.055, you have to enable C1E, and EIST to get the voltage to drop with the load, i am pretty sure.

Edited;
The higher LLC the smaller + value , i don't recommend Ultra High for offset mode (it will most likely starve your CPU under light load causing freezes) specially @4.7~5.0
It "may" work for you and your CPU ,you will find out very quick wink.gif (there is no two processors alike )

My CPU needs 1.36~1.37v under load (to pass costume 1344/1792 blend) under fixed/manual mode and yes i run LLC ultra high only under fixed,
for offset mode LLC ultra high will cause my idle Vcore to dip down below 1.00v and that is when it will cause freezes
Here is quick rundown for you (i can run both High and Medium LLC which give me basically same Vcore under load [1.368-1.384 on High or 1.36-1.387 on medium] but different Idle Vcore)
Medium (+.065) /Idle as low as 1.024v
High (+.04) /Idle 1.000v

the medium is posted above ,here is high

What if our vids are different? I thought offset is added voltage on top of the VID? Meaning +0.55 could be larger vcore for me.

I see you suggest that C3, 6 should be disabled. Does this effect the idle frequency of an overclocked i7 2600k when overclocked. My idea is idle voltage with idle clocks. Right now i have low idle clocks with high vcore.

enable ;
EIST/C1E so both, your core and frequency drops ,
i suggest C3,6 disable for low clocks like X45 to start with (i have no problems running it enabled /LLC Reg/Med,just trying to make this guide so it works for all) ,once you set up your offset and everything is nice and dandy you can try to disable,hope this helps if you have any other questions you are more than welcome to post in my guide/thread
Cheers;)
