How to find voltage offset? - Page 6

post #51 of 69
euhm... tongue.gif I did mention all of that in some previous posts tongue.gif

I HAVE a 12h stable 4.6GHz overclock at a manual 1.395V in BIOS. (1 lower = 1.39V and that iss unstable)

That's why I want moarrr (I know the basics of regular OC, I'm 32 years old tongue.gif, now it's time to move on with offset but damn that thing is a b*tch to understand tongue.gif


But ok, I'll watch into the BIOS to see what the lowest offset value is... I did not knew there was a lowest setting... I thought you had to guess/calculate what it was redface.gif

That's the reason I do not wanted to touch it smile.gif

Bah, I quoted the wrong post.

The lowest offset you can set is 0.005 - if you try to go to zero it bounces back to Auto. I'm guessing your offset will end up being somewhere around +0.03V for 1.395V.

You do have to calculate it doing it that way. Forceman and I overclock with different methods. He starts with a target multiplier and sets a manual voltage, then works the voltage up or down to get it stable. I start with stock voltage and bump the multiplier until it is unstable, then I bump the offset.

Doing it my way takes longer, but you never have to do the offset calculation. Doing it the other way you have to calculate how much offset voltage you need to get to the manual voltage you are stable at.

Oh yeah, ofcourse there's a min/max value... never noticed it excually; on the side of the BIOS screen... 0.005-0.635 or something.

was watching TV, and will stop for today, sleeeeeep, up at 6AM :s

Did some quick reboots with these settings (did a quick IBT test for Load)

+0.100 gives in CPUZ (Idle/Load) = 1.080/1.472 and VID (I/L) = 0.957/1.3911 gave 88°C

+0.050 gives in CPUZ (Idle/Load) = 1.032/1.416 and VID (I/L) = 0.957/1.3861 gave 82°C

+0.025 gave me freeze when I came back from watching TV tongue.gif

Anyway, we'll work it out !

This is good stuff. Been researching this like crazy and I think this thread says it the best. But just to clarify... I'm shooting for an OC of 4.8ghz. I have Asrock Extreme6 z77 / w/i7-3770k and Noctua d14 HS. So I set all to stock, manually set my vcore to say 1.5, see what ghz that get's me, note coretemp vid, adjust offset accordingly.

For example (totally made up #'s): 1.5vcore = 4.5ghz. If VID =1.2.

VCORE | VID
1.5 - 1.2 = +0.3 offset to make stable?

Wait - does manually adjusting vcore directly affect the ghz you see?

Hey. I have my i5-3570k running at 4.5ghz. I can do so and run prime stably for an hour (havent tried longer) however... when the computer goes into sleep or hibernate... I crash upon resume.... its a software/voltage thing which pisses me off... keep the offset positive or + and at 4.5ghz my offset needs to be at .130 to work under load and hibernate - which pisses me off because the offset raises the voltage to 1.272 which brings more heat. about 10-15 degrees more under prime than my 1.220...

When does Ivy really start to need more voltage? this is pissing me off... is 4.5 worth it or should I just go to 4.4

i can do manual voltage at 1.220 v stable but thats without an offset so the voltage stays 1.220 at 100%load or 4% load... I dont want that either


Can somone help? either fix the state change problem or tell me what multiplier maximizes speed before voltage becomes an issue

mad.gif this thing runs at 100% load at 1.220v ..... effing sleepmode and there c3:c6 states.

No, you need to manually change the turbo multiplier to change the frequency. You've got it right on the offset portion though.

Thank you for replying without pointing out how retarded I am. haha I believe I have all the info I need to fry this b!tch. Just purchased the performance tuning protection...so it's on...in 30 days...
post #59 of 69
Damn...I just overthought it... So, I set the multiplier to what I want - in this case, x48, then manually adjust the vcore (suddenly lost on what to set the vcore to for starters?) and note the VID??

no keep it positive and it will add that much more voltage to the normal vcore
