i5 3570k core differences in heat (update) - Page 5

post #41 of 85
I would leave LLC at High - you don't want the voltage to go up under load.

As for the voltage, the chips tend to have a sweet spot/wall where it takes a lot of volts to go higher, so 4.4 might be your spot. You are plenty safe to run at 1.3V though, so if you wanted to try 4.5 you can probably get there without any danger. It's only once you get up to 1.35V or so that I'd start to get worried (as long as your temps are okay, of course). Practically speaking though, there is no difference between 44 and 45.

il stay at 4.4 then. Im personally happy with that number and i feel happier with the volts lower.
i ran prime over night and had 2 workers stop but no crash so im adding.005 power and restarting.
LLC on high

How long should i be runing prime? 8 hours?
Also should i be checking whea errors for stability?

yes always check for whea errors, if you have some it means u are slightly unstable, and prime id say 12+ hours

ok had a bunch of whea errors at 1.24 voltage so i raised it .1 to 1.25.

Now runing LLC high 1.25 volts at 4.4 core speed.

Going to let it run 9 hours and check.

How would i go about finding my offset voltage after this.

(edit: meant 1.24 and 1.25)

2.5? do you mean 1.25v? lol because 2.5v would kill your cpu...and I thought you were already on offset voltage are you not? When it idles does your voltage decrease? If yes then you are on offset voltage.

ya i fxed that tongue.gif. i keep putting 1.2 or 2.2. i just subconsciously want to pump some voltage in my chip i guess haha.

im on fixed voltage. my voltage stays the same at iddle. 1.248 in cpuz and does not go down.

i dont know how to use offset yet tongue.gif. I figured it was a good idea to find a stable fixed voltage oc first before playing with offset.

(update)

prime 95 worker went down and had some whea errors at 1.25 so i set it to 1.26.
cpuz showing 1.256 volts at iddle and 1.24 at load. so there is a slight vdroop. LLC = high (50%)
restarted prime 95 with those settings. fingers are crossed lol.

Once you get a good stable voltage it is pretty easy to switch to offset. Go into the BIOS and change to offset mode, and then set a small offset to start with (say +0.005). Boot up and put a load on the system and check the actual voltage you have (in CPU-Z). Then go back into the BIOS and adjust the offset as required to bring the voltage to what you found you needed initially. So if you need 1.255V for stability and the +0.005 offset gives you 1.250V under load, you'd want to change the offset to +0.01 and you should be all set.

It's at 1.27 volts in bios and CPUz shows 1.24-.25 at load? Does that seem fine for 4.4? Also when I switch to offset would I keep llc the same?
post #49 of 85
That voltage sound fine, 1.25V is in the ballpark for 4.4. That's a bit more Vdroop than you'd normally see, but if it is stable I'd leave it alone, especially if the next level of LLC pushes the load Vcore above the no-load voltage.

When you use offset it is normally best to keep a middle setting for LLC, so what you have now should work fine.

Im at 1.24 at load and 1.27 at idle. If I understand correctly I'm measuring my voltage at load? Is it bad if its at 1.27 at idle?

What's no load voltage lol?

If I understand correctly when I do offset my voltage Will go down at idle and go up at load. Lets say I need 1.250 for stability then il want my offset voltage to hit 1.250 at load in CPUz correct?

Il check prime 95 when I'm home. I left it stress testing. Under what temps should I ideally be staying under?
