Voltage not adding up

Hey all,

Specs: i5 2500k @ 3.3ghz stock
Asrock z68 extreme 7 gen 3

My CPU at stock settings runs at a maximum of 1.200V under intelburn at full load so I figure I have at least another 0.150 to easily keep it under safe volts/temperatures.

The issue I am having though, is even with the smallest increment to my Offset Voltage of +0.005, along with the turbo voltage (which I cannot disable) to the minimum of +0.004, ( = 0.009 fyi) my cpu immediately jumps to 1.336v :confused:

LLC is set to 5 (0%) - if I run it at anything else, the voltage spikes up to 1.4's.

It runs fine at 4.4ghz but feel I could lower the voltage some - but can't...

Have tried resetting BIOS settings numerous times and reflashed it to latest version of 2.30.

I have previously OC'ed this and cannot remember having such issues.
Is my maths seriously defective or is this not adding up the way it should.
 
its the llc level that's bumping things up,so a lower llc and same offset or slightly more offset will allow vcore to droop more = lower load voltage

best to try different llc levels,one lower than turbo and different offset amounts till you get the right balance

(edit ahh its different on asrock) 0% llc then maybe try a - negative offset?
 
Just tried your idea and changed it to the smallest negative offset of the same amount, -0.005 and it seems to have brought it down from a max of 1.336 to 1.328.

But from all the Overclocking guides I have read, never have I seen someone needing to LOWER the vcore, why is my board so special ...:confused:

Perhaps I should switch to fixed mode to actually get some control on this board.
 
nah fixed mode wont idle the cpu

just depends on your cpu or how well the bios is imo,negative offset is fine you probably have a higher than need be default vid
