What you say that your device makes me thinking is really good thing decreasing stock voltage and same time increasing stock frequensy when overclocking?? i cant get stable cpu if i go 4800mhz with 1,5125v but i get stable cpu 4600mhz with 1,5125v so i think myself now that 1,5125v can be good voltage for 4600 mhz because 4800 mhz doesnt work anymore with 1,5125v so 4600mhz is close that highbound what i can get with 1,5125v.I havent try can i use 4800mhz if i go over 1,5125v because i dont want kill my cpu i dont know how much voltage my cpu should really stand in safe overclocking.
Here's the best way to start overclocking a PIledriver CPU (general guide)
From the BIOS
1: Load Optimal Defaults
2: Disabled Turbo, Disable Power Saving features, C'n'C, APM, C1e, C6, put LLC to 75% or Ultra High, set the CPU/NB Voltage to 1.25v, save settings and exit the BIOS
3: Back into the BIOS - find what your stock CPU voltage is with turbo disabled (it will be lower now)
I don't think Gigabyte has a Manual Mode for CPU or CPU/NB voltages. But if yours does, then manually set the voltage to whatever it is for the CPU.
Once you have all that set, then you should try and find your max overclock with the stock voltage. It will probably be around an extra 400-500Mhz.
I recommend to test with Prime95, because it will show you if an individual core fails stability. If that happens, then increase the CPU voltage a little.
Each time you increase the CPU Multiplier after you find your max overclock at stock voltages, just increase the cpu voltage by a couple notches and re-test.
If the computer BSOD's then it needs a couple more notches. If just a single core fails, then just increase one notch.
