4790K 4.7Ghz+ voltages?

.:SAmSuNG:. · 14 Aug 2015 at 16:38

Hi im sure there is plenty of people on here with this or similar chips on here.

Im happy with what to set CPU Vcore and Ram voltages.

Its the other voltages Im not sure about.

These are the same voltage options I have on my board (Not my settings or screenshot).

So what to set:

VCCIN Voltage
CPU Ring Voltage
CPU SA Voltage
CPU IO Analog Voltage
CPU IO Digital Voltage

Thanks.

I'd start with 1.3 vcore and 2.00 VCCIN and 47x cpu ratio and work backwards, ring ratio set it at 40x from auto.

Leave everything else on auto voltage and leave uncore on default ratio you can increase uncore afterwards although overclocking uncore doesn't add much.

Overclocking the uncore can lead to stability issues and there's little or no benefit running it at a 1:1 ratio ie 47x if the cpu ratio is 47x.

Use this guide it's great, http://www.overclock.net/t/1411077/haswell-overclocking-guide-with-statistics most people need 1.9-2.1 vccin for higher clocks.

It's all about vcore and Vccin on haswell.

I'll paste my settings tonight for 4.6ghz

Here you go, here's 4.6! - ( 4.7 ghz on mine needs 1.35v )

Thanks Im at 4.9Ghz 1.35v and its pretty stable just needs a few tweaks I think to get fully stable. Here is a screen shot. You guys see anything that could do with a tweak?

"pretty stable"

Have you tried Asus Realbench in both demo and benchmark mode?

"pretty stable"

Try some encoding with Handbrake.

On mine I have the following set fir 4.7.

Vcore, 1.300
Input, 1.800
SA, 1.200
IOA, 1.200
IOD, 1.200

Its recommended that input voltage should be 0.5v higher than vcore. My Asus board also has a setting known as PCH voltage. For this I have 1.200 set.

Vcore - 1.275v
Input - 1.8v
SA,IOA,IOD all 1.15v

Yes passes benchmark fine

I dont encode so as long as its game stable thats fine.

Thanks will have a look.

More vcore will probably change it from pretty stable to stable

Mine passes benchmarks at 1.36 for 4.9 but i run it at 1.37 just to make sure its solid. I tried tweaking all them other voltages up and down when i was trying to get 4.9 at a lower voltage but non of them allowed me to lower the voltage on the vcore so in the end i just set a higher vcore and left the rest on auto. Input .5v higher than vcore like somone else suggested.
