on CPU voltage chose "offset" just below that there will be a drop down again where you need to chose between "-" and "+" . Now to simply explain what sign you will be using, you need to use applications that will tell you what default voltage ur CPU is currently using like cpu-z.
Now for example your common voltage range is already on 1.37v. and you just want to OC to 4.2ghz. If you will ask me, that is already high or over power or more than enough for just 4.2ghz clock (it is considered as a standard class chip) You can leave it as it is coz 100% it'll work but leaving CPU offset voltage to "Auto" is a big NO, your system can easily give you 1.5v or even higher CPU voltage.. that already exceeds the boundary. So if you want to fine tune your system and lessen that CPU voltage to what is only needed, here's how... You will be using "-" sign to lessen that CPU Voltage, you need to chose "-" and just below that, there will be a box which is known as "CPU Offset voltage". In its box there will be the word "auto" on it. You can change it to a certain value that you like or just use the -/+ sign on your keyboard for 0.005 increment per click. So for example if you are on 1.37 volts and you will be using "-" and you put 0.005 value on your CPU Offset voltage, that will be.
1.370 (current voltage)
(CPU offset voltage)
1.365v (you can see the result if you will run cpu-z applications once you are running windows again)
The more CPU offset voltage you increase with "-" sign, the more CPU voltage it will decrease on your current CPU voltage.
if your CPU current voltage is like 1.1v and you want to OC to 4.5ghz. That is too low for your system to run in 4.5ghz, chances are.. Your system wont boot up, or hangs up, will reboot or you will have BSOD. dont panic.. all you need to do is increase your CPU voltage using CPU offset voltage..
So this time you will be using the "+" sign.. the more cpu offset voltage you will add, the more CPU voltage you will have. Don't just guess what numbers you will be placing on CPU offset voltage. Use +/- sign on your keyboard for 0.005 increment. I always test my system for stability every increment so, i can make sure that my system is using only what it needs to run. If your system wont boot up, increase offset voltage. If it hangs, increase again, if it boot up but with BSOD, just increase again until it boot up without any problem. then run test. If same issue occur, dont lose hope, just increase again until you can run a test for minimum of 8hrs without experiencing system failure.
No extra voltage means lesser heat and less power consumption
BTW: you can set your DRAM voltage to 1.5v (manual/standard) while tuning your system. This will lessen your problem regarding RAM issues upon OC'ng
Also: always take note of your temperature, staying below 80c is desired but staying below 70c on full load is awesome Edited by SpEaKeRb0xXx - 12/31/12 at 10:41pm
