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 (
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.

just a little update-i figured out that by changing the Dynamic Vcore i was able to control the Vcore.
any way- i set it to -0.130 which gave me a Vcore of 1.2V
so i ran Prime 95 for 12 hours without any problems and and it seems that i've got a stable OC
4.3GHZ running at 1.2v
max temp of 53C after 12 hours of prime.

does it mean that i've got a good chip?
