Hello all,

I am a recent owner of a Z170 Pro4 board paired with a i5 6600 (non k).

The options available under OC Tweaker- CPU Configuration seem to be substantially less than what is shown on the manual and also to what was present with the original bios version.

I am running bios version 2.80 but tried 3.00 and all the previous ones without a change.

The only options I have listed are:

BCLK Frequency

BCLK Spread spectrum

Intel SpeedStep Technology

Intel Turbo Boost Technology

Long Duration Power Limit

Long Duration Maintained

Short Duration Power Limit

I know that running a non-k CPU limits some of the entries but I am fairly certain the original bios had more

Can anybody confirm what's available in their menu?

You will want 3.0 as it will allow BCLK overclocking. Other settings may have been present in an older BIOS revision but they likely did not actually work. I had a BCLK option on my H170 board in an earlier BIOS version and it did nothing at all to the BCLK no matter what I set it to, the current BIOS version for my board no longer has the setting as it was non functional. This is probably the case with your board too. Also some settings will not be available when another setting is disabled.

All you need for a non K CPU however is BIOS version 3.0, the BCLK setting and CPU voltage settings.

Thanks Xaltar,

I have tried 3.0 but was unimpressed, I get much better stability with 2.8

However consider that I use the built-in GPU (waiting for a new GPU).

I do not understand why when setting BCLK to anything above 100 in UEFI the CPU multi gets reduced to 32 with no option for me to change it.

The only workaround is to set both Multi and BCLK in windows using A-Tune.

Seems like somebody forgot to add something, maybe will be fixed in the next bios version.

Ah, using Sky-OC (BCLK overclocking with 3.0) will disable the iGPU so you will need to hold off on OCing till you get a dedicated GPU. Once you do you can set the BCLK to frequencies over 104/5 without losing stability.
