Overclocking my i7 4790K

[MorbidAngel]

Hey guys I'm just done overclocking my GPU and moving forward to push my CPU even more, but I have some questions!

First of, why can't I change the voltage myself? I removed it from auto but everytime I try to change the voltage it displays in a red text and I can't change it..

And what voltage is good for my CPU? I've changed in my power settings in windows so that it can throttle down if I'm not playing or anything, right now I have it at 4.8 GHz at 1.390V, but it sets the voltage automatically and I read that 1.390V is NOT good for this processor..

Any tips?

Thanks guys!

Here's your spec sheet:

1.39v is fine provided you can keep it cool.

You sure? Max temp is 70 and that is when I'm benchmarking, so not when just playing some games and such!

Yes it's fine, I myself have done 1.65v through my CPU multiple times, and know others who run 1.47v 24/7 and barely saw any degradation after a year.

People vastly overreact to voltage on here, anything under 1.4v with a good cooler is fine for 24/7 use.

 

 

If it even was to die from overvolting, it'd take years and years, and by that time it'd be time to get a new CPU anyways.

Usually people say that 1.3V is the limit for 24/7 overclock.

This is said to prevent degradation and to keep people from doing stupid things with their CPU.

 

But for going balls to the walls you can go as high as you want, provided you keep the CPU cool

Your voltage issue is strange as you have an overclocking mobo and CPU. I haven't got much experience with MSI boards but have you checked the manual to see if there may be a way to unlock it. On my mobo if I wanted to go past 1.4V I would have to enable the jumper on the board to allow that.

woah, nice OC & voltages you got on that CPU

Okay thanks Gonna try 4.9 and see what the voltage lands on

Yeah on my i5 4670K it worked perfectly fine changing the voltage myself!

Been experimenting this week, and i've hit 4.7GHz @1.25V

I've been really lucky with my chip.

@1.3V i was not 100% stable at 4.8GHz, sadly.

Have you updated the bios for the devils canyon cpu's since the board is z87 and may be why it's causing issues.

According to MSI Live update 6 I have the latest BIOS, but according to my BIOS, I don't, but when I tried to update earlier I was going to save a backup on my USB Flash drive and the current BIOS was named "name.A11" and A11 is the latest BIOS x)

I couldn't find that on MSI's site I only found these; http://eu.msi.com/support/mb/Z87S02.html#down-bios

It only goes up to A7 on there.

Yeah that's where I went as well

Did it say manual on the voltage in the bios or does it stay on auto?

I got 5.0Ghz stable during winter (Idle ~30C, Stress ~70C) with a 1.35v OC. Too bad summer made me dial it back to 4.7Ghz.

That's sweet mate, you're at the top of the lottery

I can choose "+" or "-" that's it, but I still can't change voltage, I don't know if I'm changing the wrong thing but I changed EVERYTHING that had with the CPU to do, and nothing made it go away.

Does it do anything if you press enter when it's highlighted? I was looking up similar issues with MSI boards and I came across one similar to yours they were saying press enter when auto is highlighted and then use "+" and "-".
