4790k Recommend Voltages?

[UltraNeonGaming]

What are the minimum, stock and max recommended voltages for a 4790k?

I am currently overclocking and stress testing with Intel XTU.

My current overclock is at 4.4Ghz (All the time) with 1.248V (Stock voltage before any overclock) temps never go above 68c on my NH-U14s with MX-4

Any help would be great, thanks!!

MIN - Depends on chip

STOCK - Not sure

MAX - I'd stop at 1.35v for daily OCs

[KamiKatze]

Depends on the quality of the chip but 1.25V for 4.4 GHz sounds realistic even for manfual overclocking.

 

1.3V is considered safe with haswell CPUs and some even go 1.35 but after that it gets messy. Or at least the temps go up rapidly.

Stock also depends on chip and motherboard.

Thanks for the replies! I just finished a 10 minute Intel XTU stress test with no problems

Stock also depends on chip and motherboard.

Which would greatly explain how at stock, my G3258 ran at 1.2v, but undervolted to .88v happily.

yes

Min: by chip

 

Stock voltage is defined by Intel when they bin the chip. It's between 0.975V and 1.1V (although turbo boost 4790Ks are topping 1.25V).

 

Max? Well 1.3V on air 1.35V on water is a safe way to live

[SouthernStallion]

I wouldn't go over 1.3v. My 3570k gets 4.4 @ 1.15v under air.

for stock start from 1.10v it will be stable at 1.12 or 1.13v. . on auto voltage its a prob with D.C CPUs on Z97 chipset that when it shoots up to turbo boost 1.3v+ is normal if on Auto but its not good for CPU. i'm running mine at 4.5ghz at 1.130v and its stable. when you OC it . 1.35v is the safe line . i went to 1.50v but my chip sustained that .

I am trying to OC my 4790k too, but when I run prime it keeps the cpu at 4.0 and at 1.09V. When I close the stresstest it goes up to 4.4 and up to 1.22V..

 

I don't get this..

My 4790k@4.4Ghz manually set to boost on all cores runs perfectly fine at 1.191volts, has been throughly stress tested, and I've been running it like that for months now.

I have that CPU. My temps seem to rise more around and faster after 1.3 V. I've done extensive overclocking. I actually just had a crash at 4.8Ghz and 1.312 V. I was very mad. I was importing some high bit video into a project. After that I reduced it to 4.7Ghz @ 1.31 V. My temps seem oddly high at idle around 35-38c which I'm concerned about and my PTPP from Intel hasn't been confirmed yet. As soon as it does though, I'm prepared to crank it up to 1.35V to get at least 4.8Ghz for daily, because who cares, it's lifetime replacement. I plan to upgrade within the timeframe that I could kill 2 CPUs anyway. 

 

Beforehand, rendering hardcore video at 1.312 V (1.322) with an H110 kept my temps under 70c easily, highest I saw was 71. My chip is little fried already, since long story short, I accidentally burned it in with a 5 minute test shooting it up to 100c. So I'm not surprised it's being weird. USING PRIME95, which is evil.

DO NOT USE PRIME WITH HASWELL. They mess with voltages and can actually damage your cpu.

 

Get Aida! PLEASE.

I'm personally at 1.182v @ 4.5Ghz, IBT and Aida64 stable. Still runs hot on a h100i even at those voltages.

Holy crap, I didn't see that he said "Prime"

Aida seems to be a paid service, got any free stuff?

Intel XTU (Extreme tuning utility)

It's what I use to stress test

Aida is paid, but you can download a demo which does exactly what you need it to
