OK... now I understand. You will need to check and make sure you have the latest BIOS... some of them are a little late to the party with the OC gig.
First thing, and this is borne of my experience OC'ing my G3258, don't immediately pump up the voltage, leave it on auto for now, BUT, I would bump up the Vrin, to see if you can stabilize it, and work your way up in .2GHz steps. My chip did not respond well to a lot of voltage, but I've concluded part of that is the mobo and it's power delivery. YMMV.
I did some research on other sites and found this. Something is blocking the turbo mode or the turbo mode doesn´t work at all!! I have the option in BIOS, but it does nothing, if I set it on Enabled or Disabled, it still reboots at the windows logo screen (when I increase the multiplier - tried to increase every voltage option, disabled/enabled every function like EIST, C1E).
Then I ran across the program called ThrottleStop and it confirms my my speculations. It has an option to increase the multiplier in Windows. When I put the multiplier to 40, the CPU-Z shows my current core speed at 3200 MHZ.
BUT the multiplier in CPU-Z shows this : x 32.0 (8 -
40). So my system detects that setting, but the turbo mode never applies, it just won´t run a single digit above 3200 mhz, where turbo should start. On the other hand, downclocking affects my core speed immediately without any problems.
The only thing which I didn´t try and which I´m avoiding right now is reinstalling my OS (though I really don´t know how it should solve anything).
Of course there is a possibilty I have a faulty board right from the start (bought it last December). I even changed the order from H81M-K to H81M-C so i can OC it. Looks like I picked the one that can´t OC the G3258 as well, at least in my case.
