***Official Ivybridge Overclock Thread***

anyone know of a good guide to overclocking a 3570k on a gigabyte Z77 D3H? been a long time since i went in the bios and the amount of settings on this are crazy compared to my last board!
 
so far i've got 4.5 using 1.23v - 1.24v, folded for 8hrs temp ~61c, prime95 (small ffts) ~72c. all seems good but would appreciate if someone checks my settings are ok/could be improved. idle is something like 1v and 24c-30c

settings:
pll: disabled
c3&c6: disabled (gonna look at turning them back on)
offset: +75
llc: 75%
current cap: 140%
vrm frequency: auto
spread spectrum: on
phase ctl: optimum

is having the cpu current capability at 140% ok, it seems to keep defaulting to this not sure why...

if i enabled/auto pll i was getting 1.38/crazy volts after windows had booted, i tried a negative offset but then couldn't boot. i have a feeling i was doing something wrong but really not sure, am not fully understanding the vid/vcore offset thing atm.
 
Pretty much yeah folding everytime my pc is on and not gaming, though I do fold during D3+Sc2 without any lag.

IBT 50 times run and I hit 90c on one core, though with folding and prime they stay around the 65-75c range. I don't think I'll increase the voltage anymore. Been folding, priming/IBT for the past two days on this settings without a blue screen so hope I can stay at this voltage. If it requires any more, I'll drop it down to 4.4 and lower the volts a bit.

Also love the way this chip drops off in temps instantly. It seems to go from 90c to 40c when IBT and load programs are turned off. My former AMD 955 would be at 55c load then when I turned it off would gradually climb down so slowly. Using the same antec 620 push/pull

Yeah, 4.8 seems pretty doable on 1.2V for me.

IBT very high temps averaged out around 86. One core peaked at 91.

Max temp hottest core reached was 87 in prime.

Think I will settle there, do more stability testing, and one day a year or so from now, remove the IHS, and see where I can get around 1.45V :D

4.8 @ 1.2V ????!! thats an amzing chip if stable

that was under load in IBT. Would vary from 1.192V to 1.208V, usually 1.2V

Under load in prime it will be anywhere from 1.2V to 1.232V, usually around 1.216V.

Either way, even if I still only need to nudge it up a bit, it's still a pretty decent chip i'd say :)

Decent.... if you are 100% stable... you have 4.8Ghz with the same voltage required for everyone elses 4.5Ghz

Watercool and smash that baby past 5GHz :D
 
Lol. I wonder if I can get to 5Ghz after I flip my lid and have my loop going... since I have such a hot chip I think flipping the lid and swapping my TIM should take my temp miles down.

Which part of the windows event log shows bsod and crashes from cpu instability?

Had the CPU folding all day and all night and when I woke up it was on, but frozen. Want to check what time it crashed.
