MSI Z97 - i5-4690k - Can't adjust CPU core voltage

[Do You Even Lift]

Hi every body!

As the title suggests I'm having trouble changing the voltage on my motherboards bios. I am currently trying to test it at 4 ghz but whenever I manually enter a number by typing or using the +- keys it changes nothing. It stays there in white and stays there when my bios boots up again.

The weird thing is the real voltage is displayed next to it in a slightly grey text. It seems like something else is influencing the voltage but I don't know what.

I'll be uploading some pictures soon if I can.

Thanks in advance!

UPDATE 2 / SOLUTION:

For some reason changing the voltage in my BIOS didn't change anything until it actually booted into Windows. This meant that every time I booted up after changing my voltage a little my BIOS would reset it to default even though the value I set manually was still in the BIOS settings...

My solution was to basically do the process in reverse I guess, instead of setting my clock speed and adjusting my voltage and trying to boot, I adjusted my voltage, booted into my OS, restarted and changed my clock speed.

It's a bit convoluted, but it worked. I have no idea why it worked this way, it was probably something that I screwed up, but just in case anyone else has a similar issue and finds this thread from Google or something I'll leave this here.

It's probably because your "Cpu Core/Ring/GT Voltage Mode" is set to auto. Set it to manual.

Can't reply directly to you on mobile but I tried what you said but with no luck. There is no manual mode for the option you mentioned, there's adaptive, override and offset. Offset is the only one that appears to change anything but it splits CPU core voltage into four separate options.

With this method it seemingly lets me add voltage(?) but I've never seen it done this way so idk.

Here's what it looks like.. Wtf is going on?

Ok this can't be right because it won't let me enter any value past 0.049...

Also accidentally set the wrong post as solution while browsing on phone FML

Alright, unselected my post as best solution.

OK, override and offset correspond to what I was thinking with manual. To the best of my knowledge:
Override will let you manually set a fixed voltage.
Offset basically adds that amount to whatever value the mobo would normally be supplying.
I think adaptive let's the mobo try to figure out the best voltage on the fly.

Are you sure you aren't able to change the value with override selected?

As far as which one to pick and what to set it to, I'm sure there are plenty of haswell over clocking guides out there you can look at.

I have been following the guides as closely as possible, I had done everything up until the part where they change the voltage. I just can't seem to find a guide for this particular motherboard/BIOS.

Even in override mode when I entered a number the voltage didn't appear to change. No matter what I entered the greyed out voltage number to the left would stay at around ~1.050v-10.70v and I wouldn't be able to boot to the OS.

Hmm, I'm not sure. Try entering a value, and then saving and exiting BIOS. Maybe the grey value is the current value, which won't change until you reboot. Alternatively, try changing the value, restart and boot into Windows, and look at the voltage while running a stress test, and see if it's different than it is with the voltage on auto.

I'm not sure what the best way to go about that is. I tried running OCCT for a couple of minutes and this was the result:

I set the voltage to 1.15v in my BIOS without override on, i'm going to try it again now with override.

UPDATE:

Okay, I think I see what's happening but I need to try it out some more. I think wevery time it failed to boot into the OS it was resetting my voltage to the default setting and launching with that default voltage.

When I changed the voltage without changing the clock speed the system could actually boot up and when I restarted it the voltage was staying solid at the number which I had set.

At this point it's just a guess based on everything i've seen so far, i'm of course not an expert but i'm going to try it out a few more times to see if I can actually get some results now.

Thanks for your help.
