Hi guys,
I was trying to Overclock my i5 4670K, and so far no problems, I reached 4.2Ghz with no problems andhonestly I don't need more, as I am not interested in having top results. My only concern is the way that the gigabyte deals the vcore voltage, if I leave it on Auto, it goes up to 1.365v which is extremely too much, but the fact to leave the setting on auto, does reduce the voltage in case the cpu goes down to 800mhz in idle situations.
As 1365v was to much I decided to reduce it, and I reached 1.200v, did a copule of usual tests and everything is ok. The only concern is, that now, even if the multiplier goes down to 8, so 800mhz the voltage of the vcore stays fixed at 1.200v, which is a non sense. Is there any way to have a variable vcore with this board without setting it to auto? I found the vcore offset but i really does not help. Any suggestions from any of you who has a gigabyte motherboard?
 
Hi and welcome to the forums. :)

Do not leave vcore on auto. Most boards will over volt as you have found. To get the voltage to drop at idle you need to apply it as a offset. Mine for example has a offset of 0.65v applied which gives me a total of 1.265v at load. Gigabyte boards call thing's different names to Asus boards so ideally you want someone with a Gigabyte board in here. There is a Gigabyte overclocking guide here which may help.
 
Using offset is the right way to do this (to keep the voltage reduction).

The offset is what you want to ADD onto the stock vcore when under load.

Another thing that can stop the speedstep and vcore reducing is by disabling the 4-5 C states at the bottom of the advanced frequency page.
 
Hi there, thanks for the answers.
Pastymuncher thank you, as unintentionally you helped me understand how to use the offset, you see, before I was using it the different way, I was puting the vcore to 1.200 ands the offset to -0.200 in order to let it drop down. But as you said, I should put it higher. I'll try that. for stulid, yes all thos 4-5 C States are all enabled, that's why I can't figure why the vcore stays fixed.
 
It implies having constant high temperatures, as the voltage given to the cpu is always at full, even though the clock is at minimum, it will receive power as it was a full, pretty much :)
Anyway thanks guys, I managed to solve the problem setting the vcore to normal and the offset to +0.040V, so now at 4.3 Ghz the vcore is at 1.205V and at minimum is at 0.760V
Thank you all

What's wrong with a solid voltage regardless of clock speed? I'm not saying it's OK, I'm just wondering what the answer to that is.

It won't lower the voltage at idle so more power draw and higher temps. Haswell's power saving options can be extensively tweaked with a decent motherboard. Just browsing the internet and idle I have got my whole pc down to just 62w power draw at the wall yet when I am gaming the power just ramps up as it's needed.

I don't touch the offset.

My vcore sits solid at 1.2 (with LLC set to extreme it never fluctuates) and my multiplier dips to 800 at idle as opposed to 4.4 at load. My rig draws 80w on idle, and obviously much more on load.

It's a 4670k on a Gigabyte Z87-OC.

I think we're achieving the same result in a different way?
 
In terms of watts consumed yes, but your cpu is getting more power than needed when in idle, therefore higher temps.
Also by doing so you are shortening the life of your cpu.
