Adaptive mode vs manual mode?

[Madluri]

Hi I had a question. I overclocked my 4770k to 4.4 ghz at 1.080 on adaptive mode, but when I switch to manual mode i can't even boot into windows unless i put the voltage at 1.170. Can anyone tell me why that is happening?

And half the time i boot into windows on manual mode with 1.170 volts, its not even stable

It's an unstable overclock, that's my best guess. Also that is probably too little voltage for a 4.4ghz OC

It seems fine when im in adaptive mode though

Have you tried running any stress tests for 4+ hours on that OC? not prime 95, it messes with the voltage. Try something CPU intensive like cinebench

Thats because your motherboard automatically ramps up the core voltage when needed. If your CPU is only at 1.6GHz at idle, it only needs 1.080v, but when it goes to 4.4GHz the voltage will go up to whatever amount it needs to be stable. This was you can have your voltage low when at idle, and only have higher voltage when actually needing the 4.4GHz. This also extends the lifetime of your CPU and keeps temperatures cooler. I suggest you keep it on. If you have some tool to monitor your voltage when in windows, run a CPU benchmark such as prime95 or something, and watch the voltage go up. This keeps your CPU stable 100% of the time

Ok ill try that

Thanks a quick question, is 1.20 volts at 4.4 ghz stable a good chip?

It is good yes, but not outstanding. I have seen some people on the forum reaching 1.3 or 1.4 just to get 4.3GHz which is really bad. My 3770k does ~1.15v for 4.6GHz which is very good. You have a good overclocking CPU
