First, telling us what application you use to see those value will help alot, just to be sure were on the same boat.
I want to stress this out, Using AUTO on your CPU Voltage and CPU OFFSET VOLTAGE is a big NO. especially if you're not on STOCK. It'll give you voltage more than what is needed and most of the time MORE than the safe limit and that scares me alot. MORE than what is needed means hotter CPU and more power consumption.
So manual is safer than auto and using CPU offset voltage is better and easier.
Your main problem mate is you don't know your default CPU voltage or what CPU voltage to use. Like totally Dubbed said, "do it on manual first"
. Try to set your CPU voltage to what ever voltage you desire (try 1.25v if you are going 4.5ghz), i have set mine at 1.3v (that is middle value coz ive been testing my system from 4.2ghz to 4.5ghz) and that is the default voltage your system is going to use, whether it is sufficient, or not, that will be your DEFAULT CPU Voltage. If it boots up and pass the test for minimum of 8hrs then it is stable. But were not done yet, that is far from fine tuned system,
you just set your CPU voltage to where your system can properly do its task even on full load, in short you just overclocked your CPU. It might be more than what is needed to run your system on 4.6ghz so NOW
you will be using CPU Offset voltage to lessen that DEFAULT CPU voltage, that'll save you from constant changing your Default CPU Voltage. Now for example, If your system is running at 4.6ghz under 1.3v and pass all the test for 8hrs and you think it is stable, that manual CPU voltage that you input is sufficient enough or possible that it is more than enough. So you will be using "-" and lessen that voltage till you find that sweet spot where your system is running smoothly on full load with lesser voltage. how to do that?
you have 1.3v, use "-" sign for cpu offset voltage, click the box and hit positive sign on your keyboard, it'll give you the value of 0.005v. So 1.3v minus 0.005v will give you, 1.295 CPU Voltage. Run test, if still stable, repeat the process while increasing your CPU offset voltage. Now if your system became unstable, go back to the last value of your CPU offset voltage where your system runs smoothly. Now your system is OC'ed and fine tuned.
Now just in case that you input 1.1v manually to be your Default CPU voltage. And you want to over clock to 4.6ghz, that is most likely insufficient. Possible that your system wont boot up, crash down, hangs up or BSOD. SO instead of changing this 1.1v value, just use CPU Offset voltage. Use "+" sign, click the offset box, then key in some value or if you have the patience of a NUN then do it on 0.005 increment then run test. Example, 1.1v "+" 0.100 cpu offset voltage
, it'll give you 1.2 CPU Voltage
. Fine tune your system to just what voltage is needed.
that is how offsetting works
Know your CPU from top to bottom.
Knowing and setting your Default CPU voltage is necessary in OC'ng
OC'ng is very easy, just put some value on your CPU voltage, if it works fine then you're done... But fine tuning is a very different story, it takes alot of time and patience.
