Can someone please help me make my CPU throttle to 1.6GHz when idle...please lol

[TonyTurbo78]

Hi guys, this is doing my head in. Here's the issue.

I have my I7 3770K able to pull 4.6GHz with ease when setting Vcore manually to 1.2v. Now the only problem with that is, my CPU does not throttle back to 1.6GHz and drop volts at the same time when its idling. I have all the power saving options enabled in Bios to throttle but its not happening for me. I'm not using Intel Turbo, I've just manually set multi to 46 and set vcore to 1.2v manually. How the hell do I set my Bios up so it when my CPU is idle it drops to 1.6GHz and also drops volts to default and when I stress it the chip gets to 4.6GHz with using the 1.2v I set?

I'm using Gigabyte Z77 UEFI Bios. This is what my Voltage page looks like as default, this is not actually my bios, just a pic off the net. Basically I have Vcore set to 1.2v and the others at Auto.

This is driving me nuts.

you have to set cpu voltage to "normal" in the cpu voltage list,this will unlock dvid (dynamic vcore or offset)

then you can maybe try +0.025v and use high llc

only use small amounts of dvid and make sure the first digits are 0 so +0.0

stock cpu voltage + dvid + llc level = total load cpu voltage when stressed,so you need to get the balance right

I've tried that Wazza but i cant get it to boot when setting vcore to normal. I'm using Turbo llc

I think im going to take some pictures of my bios on the camera and show it properly. I know my chip does 4.6GHz at 1.2v I just need to figure out how to get this without manually setting the vcore at that. I dont want my CPU running at 4.6GHz @ 1.2v 24/7

 

[wazza300]

cos your not adding extra in dvid and depends on what level llc you use,look at this guide for 4.6ghz

copy the settings but enter your own ram settings

You need to also make sure all sleep/C states are on.

You need to also make sure all sleep/C states are on.

they are on thx

 

[wazza300]

yeah

and it wont throttle with a fixed cpu voltage it has to be set to normal and use dvid/offset

the higher llc you use the lower dvid needed and vice versa

 

[TonyTurbo78]

ok going to mimic those settings.

So when you set normal for Vcore, what voltage is that actually setting?

 

[wazza300]

it uses the default cpu voltage set by intel for each chip

you then add extra in dvid with a + or take off/undervolt the cpu with a - till you reach your stable oc voltage

remember each llc level will add a chunk of voltage ontop of dvid

 

[TonyTurbo78]

so then, when im setting x46 multi and normal Vcore thats actually only giving the chip .08v or whatever stock volts is for a 3770K. You need the PLL to take it to 1.2V correct or not?

 

[wazza300]

yeah it sets it to use stock volts for the cpu (normal does) then you use dvid to add what you need to be stable for each oc

pll is different

llc will add some more voltage but no idea how much each level adds,hence to use tiny amounts of dvid at a time

 

[TonyTurbo78]

just tried that, just going to bloody leave it at 46 multi and vcore 1.2V 24/7 lol...Ive just spent the last 15minutes trying to not have it freeze in bios because not enough volts, quickly load defaults and managed to get in and set it to where it was. Couldnt be arsed to pull both my GPU's out because my reset bios switch is right below them lol.

I'll try again tomorrow, just want to enjoy some games tonight.

 

[wazza300]

are you setting 1.10v cpu/vtt for 16gb of memory? might help

it will work you just need more dvid or a higher level llc as each cpu is different

 

[TonyTurbo78]

nope just leaving it on auto mate

 

[mmj_uk]

Have you tried putting your chip back to stock, setting the offset core voltage so that gets to 1.2V and then setting multiplier to 46?

 

[Orcvader]

Have you also made sure the Windows power profile is set on balanced and not high performance?

 

[TonyTurbo78]

no and no to the last 2 questions lol.

 

[TonyTurbo78]

Have you tried putting your chip back to stock, setting the offset core voltage so that gets to 1.2V and then setting multiplier to 46?

how would I set the offset voltage to achieve that? thats what i been trying to work out

 

[wazza300]

all you need to do is use one or two more clicks dvid voltage,and set cpu/vtt voltage to 1.10v

Reset to optimize defaults (F7) and start again.
Raise to x42 and set to normal in cpu v core.
check in cpuz when stressing with prime and then add more offset voltage and raise your multi from there,stress again. keep going till reach your required speed
