Overclocking Decisions

[Geralt]

So with my new rma-ed H80i, I'm at 1.35v for the Core Voltage at 4.6GHz with 100% load temperatures at 70C both with Aida64 and XTU

 

Is 1.35v safe for a 4690K? I've read that I should not exceed 1.3v but since it's a H80i, I figured I push it further. What's the absolute safe limit for the voltage of a 4690K?

Just curious about how you guys do your overclock. For example, I'm currently at 4.4GHz on my 4690K with 1.250 volts, would you stay at this or go up to 4.5GHz but the voltage at 1.300 volts? It's a very significant increase in volts for just 100 MHz so what do you guys think?

I would keep at 4.4 since you are already hitting the 1.25 mark at this point. It is too bad but seems like you lost the silicon lottery

So from my experimentation,

 

4.4GHz - Stable at 1.250v

4.5GHz - Stable at 1.300v

4.6GHz - Stable at 1.350v

 

Should I go 4.5?

More voltage means more power consumption, more heat output and a shorter lifespan. I would recommend that you go with what you feel comfortable doing.

I just want to push the CPU to the safe limit it can go without risking degradation of the chip so I just want to know the limit so I can stop there. I've seen post of people saying that I should be crossing 1.3v while some say to not cross 1.4v and I'm just confused as hell.

4.5 at 1.2v is normal for most of the motherboard.

4.5 at 1.2v is normal for most of the motherboard.

Seems my chip would be abnormal then. 4.5 is at 1.3v for me.

Guess I lucked out in the silicon lottery.

Final update.

My 4690K now runs at 1.340v @ 4.6GHz and 62.5% LLC.

What do you guys think?
