I5 2500k 4.3GHZ @ 1.356V

Hi!
I overclocked my CPU only by changing the turbo boost values to 43X, everything else is set to AUTO. prime running at about 60C

these are my specs:
CPU: Intel I5 2500k 3.3GHZ
CPU cooling: Scythe mugen 3
GPU: gigabyte 570 GTX OC
Motherboard: Gigabyte GA-Z68A-D3H-B3
PSU: seasonic 620W 80+bronze
Ram: G.skill 4GB*2 (http://www.newegg.com/Product/Product.aspx?Item=N82E16820231422)
Case: Sharkoon T9 value
HDD: western digital black caviar 1tb

with this MOBO i can't change the actual Vcore but i can change the Dynamic Vcore and i have it set to auto.
i'm guessing that 1.356V is too high for 4.3GHZ and i can lower it to about 1.29-1.3V but i'm not sure how.
so what value should i set for the Dynamic Vcore?

thanks in advance!

p.s. sorry if my English is bad

Not sure if the dynamic vcore is the offset voltage or not, but you can try +0.05, boot, test, if unstable go to +0.10 test and see if stable, watch voltage. You may need to mess with CPU LLC (load line calibration) to get a stable voltage.
If you could post a picture of the values in bios that'd be great.

it's decent .. now let's see what vcore u'll have at 4.8ghz
