Overvolting problem

First of all Hello,

I've got a Gigabyte Z87X-OC and a i7-4790K processor and whenever I want to play a game the motherboard automatically overvolts the processor to 1.47volts.
Even if I load the standard settings in the BIOS it keeps setting 1.47volts.
Is this normal for a motherboard to automatically overvolt the processor that much?
I noticed this about 3 months after i build my rig because I wanted to do a little bit of overclocking but is my processor still goed because he almost always got to 100°C and started throttling?

Have you got programs that OCs the CPU? If not, why not just read some guides, put in a little effort and get find the lowest stable voltage for your processor.
 
It sounds like you have some sort of auto overclock feature still enabled on the board. What happens (most of the time) is one of two things.

1. You have an auto overclock feature still enabled that was pre-programmed into the board to offer the best volts tested for a specific clock speed.

or

2. Your motherboard noticed inability with your OC and is over volting to prevent it from crashing.

Thats what I was thinking at first too, however the OP stated that they loaded the default bios settings, which should in theory mean that none of the OC features are active.

The default BIOS settings on an ASUS ROG board will do this so I was thinking maybe a Gigabyte board will too.
 
It is now on 1.2 volts stable with no problem but it seem that my cpu handles different then before without any overclock.

I see, though I dont think there are any switches on OPs motherboard, not 100% sure. Would have thought that the OC on the Asus board was caused by one of those sliding switches in the OC position.
 
it was my understanding that this is usually off on default, though I guess it doesnt hurt to check. I still think it would be better if OP just does things manually, as there are plenty of guides and it would only require a small amount of OP's time.

It to me sounds like his motherboard (like ASUS) by default has auto OC features enabled. With ASUS ROG boards all you need to do is put the clock speed in and it will automatically adjust the voltage (by default). ASUS as well as gigabyte it seems puts a LOT of voltage just to be safe. Nothing that will kill the CPU (unless overheated) but puts more than needed because the company felt that most chips tested passed at that speed with a certain voltage.
 
Most motherboards on the Z chipsets of the 1150 seem to have their voltage set to auto by default. When the user resets the bios or updates it they will have at least to go in the UEFI and change the voltages again, which can be catastrophic if you forget since 1.4 volts on a 4770k....

My Sabertooth Z77 also does this. I think you are on the right track though in that the OP needs to disable the OC in bios himself.
 
Go into the BIOS and set a static frequency and cpu vcore. I think this is the same problem TTL had with the z97x soc force where it would overclock the cpu and overvolt with everything at auto.
