Overclocking with software > Bios?

I've been only overclocking through Bios all these years so I have whats up with these software packages that come with the motherboards.

I just finished building a pc with a MSI Z87 AC mobo with a i7 4770k. I tried going to 4.4 and it was stable, then 4.5 and it was ok (had to go high voltage) then after a while it became unstable and 4.4 never worked again either, I figured the cpu was bad so I exchanged it for a new one along with a new motherboard, psu, etc. The only thing I kept was the hard drive with the old win 8 installation and the new chip wasn't overclocking either, which meant it was an issue with windows.

So I reinstall windows (clean install) while overclocked and everything was fine until I was finished installing all my software and updates, it became unstable again. So it is obviously a piece of software that isn't allowing me to overclock past 4.1. If I go 4.4, it just barely logs into windows before blue screening, no matter what voltage. I had gone through a detailed guide upping ring voltage, cache voltage, cpu voltage, etc.

I was pissed off and in my desperation I open MSI Command Center, I didn't touch anything, I just upped my voltage up to 1.2, moved the slider to 4.5, pressed apply and.....stable 4.5 overclock while using aida extreme.. wtf? Temps don't go over 60 using a coolermaster seidon 120m and it isn't bluescreening on me.

This is my third experience with MSI mobos and I've had similar issues with all of them, what could be the issue here?

Anyway, I am done trying to overclock through this bios, I am going to do everything from command center now. Normally I don't like this as I've run in to situations where an unstable overclock keeps me from booting into windows and restoring bios to defaults does nothing because the software maintains it's configuration so the moment it logs into windows it kept bluescreening no matter what. The thing is, I rather take that risk than having to settle for 4.1 because the bios can't do any better.

 
Hey,
The Windows software just modifies the BIOS anyway so there's nothing you can do in software that you can't do in the BIOS. You just didn't do it correctly.

(Personally, I'd just do a 4.2GHz overclock as that can likely be done while also keeping the Intel Power Management running which produces less heat. There aren't many games that run better above 4GHz anyway).

Sorry but no, I used the same voltage in the bios while keeping everything else the same, I mirror copied those settings in command center and it worked fine.

It's not as simple as that. If that were the case why does he computer work fine until after the windows updates are installed?

My guess is that when something loads while windows is starting up, something goes wrong and causes instability. When doing it through windows since "x" process is already loaded, it causes no issues.

Either way, as you say, I overclocked it with 1.2, so it's good I guess, just strange

I'll be a bit more specific.

If absolutely every setting in the bios and the msi command center software is the same, and I mean everything. Then I increase cpu voltage and go up to 4.2 overclock in the bios, tt won't boot into windows, I get constant blue screens.

If I boot into windows with the base clock of 3.5, then in the msi command software, with the same voltage as the bios, I can go up to 4.6 and use Aida extreme and temperatures will max out at 65c with CPU-Z reading the max clock speed correctly, etc. If I try 4.7 then I blue screen.

So yeah, I am happy cos I am managing 4.6 OC with 1.3 volts, (probably less, I have to fine tune) but I am pissed off because I can't do it from the Bios. It's not a bad board or cpu as this is the second mobo and second i7 I try this on (I rma both of them thinking they were faulty)

Unless MSI command center does some "behind the scenes magic" that the bios doesn't do, I can't explain why I am getting such a difference performance.

I guess I'll just stop complaining, as it does work but I would love to know the reason, it is very strange.
