CPU overclock, not downclocking when idle?

[EvilWiffles]

Ello,

 

I'm wanting to make my CPU not 4.7GHz when it's not in intense use. What do I need to change so it's not in turbo 24/7?

Running Asus Z97-A and CPU voltage @ 1.238v.

 

A step by step guide would be hopeful.

Adaptive mode

[Mushious]

Go into Windows power settings and change it to Balanced instead of Performance.

 Awesome, that helped.

I still can't get my 1.238v when I reach 4.7GHz though. I set Adaptive to 0.211 to increase it to 1.235v but nothing much happened.

There is another option below this that gives me an option to set turbo voltage, would this be the option?

 

It says on CPU-Z that my vcore reaches 1.198v when it's reaching 4.7GHz. I adjusted the turbo vcore to 0.211 and still isn't different.

Anyone?

Anyone?

 

Haswell Low Power Modes

•Cpu ratio mode- Dynamic

•Enhanced Turbo- Enabled

•CPU core voltage mode- Adaptive

•CPU ring voltage mode- Adaptive

•Intel C-state – Enabled

•C1E Support- Enabled

•Package C-state limit - Auto

 

 

for windows users also make sure you set your minimum processor state to 5%

 

Windows7

Your settings may be called a bit different but you should be good with that!

Good luck

I checked and C-state wasn't enabled, so I enabled it.

Now my clockspeed changes when idle. However, when I turbo to 4.7GHz I still don't get my 1.235v. It just sticks to 1.198v.

This is most likely what we call ''Vdroop'' it's common for motherboard to deliver less volts to the CPU than what is asked...do you have a setting called LLC or Load Line Calibration? if so...experience with that a little bit...most likely setting LLC to ''high'' should help with too much Vdroop...but his your CPU stable at 1.198v and 4.7ghz?

Well, if there is a difference in stability between manual voltage and adaptive, then I wouldn't know.

1.235v is what I typically have it set to, anything below that would cause instability.

 

I do have LLC, I'll check with that real quick. It'll be abit hard to find but I remember seeing it.

Go into Windows power settings and change it to Balanced instead of Performance.

That's bad advice...

Whenever I do that it downclocks to like 1Ghz and when I launch something demanding it halts my computer to a stop.

 

(Either that or it's a problem with 3DMark 11 as I barely had any time to test in this morning.

I tried LLC 9 (highest) and LLC 1. I ended up bluescreening on LLC1 lol.

 

In bios, CPU voltage is 1.024v.

[EvilWiffles]

I can set Dynamic CPU Voltage Offset in XTU at 19.5312500 mV and I get my voltage I am stable with...

I would just set multiplier to 46 and call it a day mate.

I'd do just that but knowing me, I'd go completely insane knowing I couldn't get my damn 4.7GHz.

[ProKoN]

 Awesome, that helped.

There is another option below this that gives me an option to set turbo voltage, would this be the option?

 

 

 

set voltage mode for adaptive

 

where it says additional cpu turbo voltage thats where you key in your voltage.

 

in your case key in 1.238 in to additional cpu turbo voltage

 

no need to mess with offsets

I leave CPU Core Voltage Offset to auto then?

[ProKoN]

yes

[EvilWiffles]

yes

 

I did that, still says 1.198v .

 

I installed the new BIOS update and reset. Still got nothing working.

[ProKoN]

should only have to change two settings

 

offset sign mode and offset voltage can be left on auto

 

core voltage mode - adaptive

 

 

additional turbo mode cpu core voltage - 1.238V

It's weird, now it's 1.200v in bios... Still 1.198v though.

 

Edit: Sweet, for some reason it started running 1.238v after a few minutes on Windows. Why is that?

[ProKoN]

run a test like cinebench r15 and monitor voltage under load

[EvilWiffles]

Yup, consistent 1.238v now. Thanks m8 .

[EvilWiffles]

Is it normal for my voltage to be stuck at 1.198v until a few minutes go by? I just restarted my computer and re-ran Cinebench and saw my voltage at 1.198v again and I bluescreened lol.

it may take a few minutes for eist to kick in.  if you run a cinebench test it should kick in shortly after the test completes.

 

at which point the frequency should drop down to 800mhz and the voltage as well

 

I do not like asus's adaptive voltage mode implementation.

 

on my z97 formula adaptive voltage does not work proper, it will reach max turbo voltage but will not drop below 1.00V when the cpu is idle, even tho it should drop to like 0.700V.

 

you have made the correct changes

 

use ai suite to monitor your voltage. you may have to increase your voltage if its only hitting 1.2V under load
