i5 3570k core differences in heat (update)

post #1 of 85
Thread Starter 
So im using a maximus v formula mobo and loaded up optomized settings. when i start my computer i run cpu-z and it shows my vcore as 2.1-2.4 (it mostly stays at 2.4) and my core speed is always 3.8.

Im a little worried because
- my core speed dosent go down even at iddle ( i have intel speed step enabled)
- and second my default vcore is really high...

Does this seem right to you guys?

Download the latest CPU-Z version or Hardware Monitor. Software readings are not perfect. If those readings were right your PC would be on fire.

Updating BIOS/UEFI also helps sometimes. Check these voltages on PC Health or whatever readings you have on UEFI.

It's easier to help if you fill your rig specs wink.gif

My 3570 stays between 1.18-1.22 according to CPU-Z and coretemp (the readings differ a little). But I'm not worried about it since temps never go over 55º.

how do i add my spechs at the bottom like you? sorry im new tongue.gif this is my first home built computer haha.

my spechs are

cpu - i5 3570k
mobo- maximus v formula
ram - 2x8gb 1600 corsair vengeance low profile
cooler - nzxt havik 140
case- storm trooper
power supply - corsair hx1050 gold certified
graphics card- assus gtx 690
OS- windows 8 64bit (OEM)

ive updated the uefi(bios) to 1604 wich is the lattest version
ive downloaded all the recent versions of these programs off their website.

cpu-z, - version 1.62
coretemp -- version 1.0
prime95, - version ?? its the 64 bit version on the frontpage of http://www.mersenne.org/freesoft/

i left the system at auto and cranked up the vcore to 45 just to see what would happen and in cpuz it said my vcore was 1.48!! i almost had a heart atack and restarted the system immediatly.

1.45v with this cooler... Not sure how it handles.

So, what you're trying to say is that your BIOS automatically cranked up the cpu vcore to 1.45, and you want to know the default voltage so you can set it manually.

Well, stock vcore is 1.15. Disable LLC if you're not overclocking (or set it to the lowest setting).

Where are you from? You can PM me if you're PT-BR.

whats PT-BR?

I know the stock vcore is 1.15 however when i load the optomized settings it cranks it up to 1.24 at stock core speed.

So bios is optomized settings.
running cpuz my core speed goes to 3.8 and then the vcore reaches 2.4. Is that normal? (edit: i meant 1.4)

Automatic vcore:

When i set my multiplier to 44 it sets my vcore to 1.4 automatically. that seems ridiculously high to me.

what settings is your i5 3570k at? stock clock or overclocked?

It can't be at 2.4, the board can't push it that high, so that's either a software error or you typed it wrong and meant 1.4.

For the full speed issue, check that your Windows power plan is set to Balanced. High Performance will keep the chip from downclocking and downvolting. You can also check the BIOS and make sure EIST, C1E, C3 and C6 are all enabled - but check Windows first.

If you want to try overclocking, I would set something like 1.25V manually for the Vcore and try a 44 multiplier. Test that for stability, and see what temps and volts it gives you under load. You might need 1.3V for 4.4~4.5, but 1.4V is very high at that speed.

Thank you! i am in high performance mode. I changed that and it fixed it!

If i set my voltage manually does that mean the core speed wont go down at iddle? or does it just mean that even when it downclocks at iddle it will be receiving 1.25 volts.

And yes i meant 1.4!! i think id start crying at 2.4 lol!!

im also using the uefi from asus and cannot for the love of god find the EIST (found intel speed step and its enabled still cant find c state section) and c state section. ive even checked the manual 0.o

Yes, setting a manual voltage means it will stay at that voltage all the time, even at idle. The CPU speed will drop though. If you want the voltage to drop also you need to use an offset. But it is normally better to find your stable overclock settings first using manual voltage, then switch over to the offset (although you can do it using offset right from the start).

Ive tried using offset.

I figured that if my bios set my vcore automaticly at 2.4 and that i need 2.5 to try to attain a 4.4 cpu then i would offset at +0.1? is that correct? i figured thats how it worked but im not 100% positive? im using an ASUS UEFI.

second under what section would i be able to find C1 C3 and C6 ? does it go by any other names?

The offset is added to the VID, which is what the chip is requesting at a given speed (it varied by speed). So if you needed 1.3V for 4.5 and your chip's VID was 1.25, then you'd use a +0.05 offset. That's why it's generally easier to set up the offset after you've got a stable overclock, since you already know the target Vcore. The BIOS in Auto may or may not be giving the VID (some boards give extra voltage).

I can't remember where the power saving stuff is (it's not where you would expect it to be) but if changing the power plan fixed the idle problem then you can just leave them on Auto (their default). I think it's under CPU Power Management, but I can't remember if that's on the AI Tweaker tab or the Advanced tab.
