Gigabyte Z68A-D3H-B3 and I5-2500k

[jr8801]

I am in the midst of overclocking my rig right now and i have found the 'cut off' for stock voltage. I am able to run my i5 at 4.3ghz stable in prime95 for 12 hours with a high temperature of 68c.

once i move the multiplier past 43 (ie. to 44) i get a BSOD during the first 10 minutes of Prime95.

So i figure i have to change the voltage.
According to CPU-Z my core voltage is 1.044v and according to Touch bios my vcore is .97v

Is there a reason for this difference?

Also in all the guides they say you must change the vcore but i do not have this option on my bios-----
In my bios all i have is

Load-line Calibration (set to auto)

Dynamic Vcore (set to auto)

QPI/Vtt Voltage (set to Auto)

The dynamic Vcore allows me to change voltage in degrees of .01 all the way to .690

The QPI/Vtt voltage allows me to change voltage from .84 to 1.70v

So which one of these options closely resembles what i need to change to get a stable clock over 4.3ghz?

I actually have the exact same combo. My auto-adjusted voltages are bit higher than yours when I moved the multiplier up into that range. Odd. What BIOS revision are you running? I know that Gigabyte spec'd F5 for TouchBIOS.

I haven't gone this far, but here's a link explaining how Gigabyte does it on their Sandy Bridge MOBO's:
