I then enabled the in OS changeable settings. in windows there is a tool from gigabyte named smart6, where I can set the turbo mode, do it to 4.4 and still have to restart (while I shouldn't have to, as I enabled the possibility to change the settings in OS), and I restart, and there isn't any turbo ratio or something.
What I am doing wrong?
It is like it doesn't mantain the settings i set.
I never overclocked a cpu, my i2600 k went on turbo mode by itself, and never felt bottlenecked by the cpu (unless using compression programs).
Have you got some suggestion?
Isn't there a tool to overclock cpu, like precisionx and msi afterburner do it on the OS???
What I'd do, is this:
1) Log into Windows and make sure Core Temp starts up together with Windows. That way you've got an accurate measure of how hot the CPU gets during startup, a fairly heavy duty on the CPU.
2) Restart your PC, go into the UEFI and reset your settings to the Safe Default Settings.
3) Press F10 to save those settings and restart the PC.
4) Log into Windows, and see what the temperatures of your CPU are like: A) during startup and B) a few minutes after, on idle.
5) Go back to the UEFI. Set the Multiplier manually to 44 on each core. Leave every other setting on auto.
6) Press F10 to save those settings and restart the PC.
7) Go into Windows and see if you get any BSOD or freeze during the startup and logon procedure. Start Intel BurnIn Test and do a standard level stresstest, just to see if your CPU can handle a 100% load without any BSOD or freeze. It should, since every voltage setting is put on Auto.
8) Now restart your PC again, but this time, set a Manual VCore of 1.3V. Leave every other setting the way it is.
9) Press F10 to save the settings and restart your PC.
10) Log back into Windows and do another Intel BurnIn Test stresstest to see if your CPU can handle this amount of voltage. If it doesn't, increase VCore with 0.05V. If that still, doesn't help, increase it again by 0.05V until it works. If it does work (read: if during either startup or stresstesting you don't get a BSOD or a freeze), however, restart the PC and lower
the VCore by 0.05V, press F10 to save those settings and restart the PC again.
11) Keep lowering the VCore 0.05V at a time until you get a BSOD during either startup or stresstesting. When that happens, increase the VCore again by 0.05V and you'll be safe again.
12) Job Done. You now have the OC you desired at the lowest possible voltage and thereby also the lowest possible amount of heat.
