help with b85m-itx motherboard

Hello
I have recently built a htpc/light gaming machine with a g3258 and b85m-itx (bios 2.20).
I have a stable overclock of 4.2 with 1.215 vcore.
I can't seem to get the voltage set to adaptive. In the bios there's an information panel on the right explaining the various core voltage modes; auto, adaptive and override
However the drop down box only gives options for auto and override.
Am I missing something?
The core clock isn't static when I look with hwmonitor but the volts are.
I can tell hwmonitor is giving me correct reading because at stock settings the voltage varies.
Any help greatly appreciated

Ok thank you asrock tsd,

PROBLEMS PART 2

So if I accept that limitation and am now regretting purchasing such a limited board my next problem is that the overclock does not stick.
Everything is stable upon first boot but upon reboot the clock speed reverts to stock speed.
I have tried a new battery but makes no difference.
The settings are still retained in the bios - the voltages stay 'fixed' as they are set for the overclock - but I don't get the overclock speed until I reboot from the bios.
Any idea what might be causing this?
I can't find much online because the terminology and the options on this mobo aren't very common.
Thanks

You lost me on this: Everything is stable upon first boot but upon reboot the clock speed reverts to stock speed.

And this: but I don't get the overclock speed until I reboot from the bios.

So from a cold start/boot, your OC settings are applied and shown by your monitoring program.

But if you restart the PC directly back into Windows, your OC settings are lost according to the monitoring program.

If you then restart into the BIOS, where all your settings are right, and save and exit (or even just exit?) the BIOS, you then get your OC back according to the monitoring program. Is this all correct?

Given some of the owner reviews I've read about this board, if you are checking Windows Performance monitor, or other Windows programs, you won't see your OC shown correctly. That is an old Windows bug that remains unfixed. A-Tuning will show your OC correctly, or a program like HWiNFO.

Tough Reality Check: Any B85 (or any Intel 'B') chipset board will be the most anti-over clocking Intel board you can buy. 'B' = Business in this case, including the board supporting the Intel Small Business Advantage 2.0 software.

You are also not going to get options like Adaptive voltage (which is generally not used by most over clocking enthusiasts) on a board like this.

Tips about this: If you want your CPU voltage to be reduced at idle, be sure the CPU power saving options are enabled (EIST, C States) and that you edit the minimum processor state in your Windows Power Plan, Advanced settings. Set it to 5% or less, which it won't be with the High Performance power plan.

Even after doing the above, you still won't see the CPU VCore going down at idle without Adaptive voltage. That's because most monitoring programs don't display the VCore of Haswell processors, they display VIDs. Core voltages are created internally with Haswell CPUs, and must be read from the processor itself. Only one or two programs can do that, if the board's sensor chip will allow it. HWiNFO might show your VCore, but I doubt it, it will with ASRock Z97 boards.

OTOH, the same owner reviews mention the "one click OC" capability of this board. If you start to set things yourself instead of using the auto OC options on this board, that might be the issue.

You are trying to get into options that aren't available on a non-Z chipset board, sorry to say.

From all my reading on the matter, which is extensive, the B85 based boards regardless of manufacturer do not support adaptive voltage unless all voltage settings are left at auto. I have tested the theory myself, with my cpu at stock (Pentium G3258) I see my voltage scale with power states. As soon as I apply an overclock that requires more than stock voltage (3.8ghz in my case), even with voltage still set to auto, it stops scaling. This is a known issue or shall we say non issue with the b85 chipset across all manufacturers. Non Z overclocking is basically a bios hack job to allow a feature that was purposefully disabled by intel. While all 8 series chipsets are in essence the same with features disabled further for each tier under Z87 these changes are not merely software. While I have heard about some B85/H81 boards that support adaptive modes I have seen no proof of these claims.

Thanks for replying guys. I appreciate it.

Perhaps this is a non-issue. What I have just discovered is if I reboot from Windows I lose my oc everytime. However if I shut down and power back up all my chosen settings remain in place.
A windows 8.1 issue? boot sequence?
Like I said I am seeing no signs of instability, bsod or otherwise

I think I can live with this. I have an i7 desktop video editing machine for real work and a ps4 for games.
Essentially this is a htpc that i will use for movies, browsing, torrents and cpu-gpu light and older games.

Still wanting to squeeze as much performance but also energy efficiency as I can out of it as it will be left on and  downloading for long periods.

Right now with my oc of 4.2 the pc is consuming 50w idling (800mhz in hwmonitor) and up to 90w full throttle (4200 mhz) with prime 95 torture test (measured through a plug in power meter). 500w silverstone strider psu.
Is this good? the best I can hope for?
