@Sin: How would I set the DVID at my OC? Would I have to manually set the vcore to, lets say, 1.28V and then set it back to "normal" so I can change the DVID to a smaller value?

More or less, my question is would I need to even utilize the DVID offset to get a 4.6-4.8Ghz OC with turboboost? How is it that people can get 4.7Ghz with a Vcore of 1.3, while mine goes all the way up to 3.9+?

Any recommendation for save levels for VTT, PLL, and IMC? Right not I have it sat to .975V VTT, 1.600V PLL, and .900 IMC

**EDIT** Well, my chip is probably not the best out there. As of right now I can only hit 4.5Ghz stable...the temps are iffy too :C

just wanted to add to the knowledgebase

msi z77a-gd65
3570k

auto voltage (runs at 1.16 under load after vdroop)
easy overclock to 4.3 ghz
pll reduced to 1.6

noctua d14 air cooling.
memory at stock 1.5v - 1600 ddr2 8gb mushkin blacklines

idle temp of 42 c with peak load 72 c
p95 stable@ 2+374 hours

able to push higher easily but wanted to keep temps low going into summer

4.5 ghz stable at 1.3 v but temps peaking into the 80s
4.4 ghz stable at 1.25 v with temps in high 70s

however, haven't figured out how to do offset voltages on this motherboard so if i set manual voltage, seems to disable the dynamic phase control voltages ???

anyways, just to help others get a sense.


not posting pics as this is well within what has been reported. just in case someone wanted to get a base reference with my exact config.

I'm doing a stability check on my oc over night with IBT at max 20 runs. I'm at 42x100 vcore 1.110 pll 1.6000. I am a super noob at overclocking but I turned off Hyper threading for my over night stability check. Now do people generally keep HT on or off while checking for stability and does my vcore and pll look alright at 42000MHz?

**EDIT**

If anyones interested a 4.2GHz as a daily driver. 42x100, vcore 1.090 pll 1.5500

Man, you are definitely in the same boat as me. I can get 4.5 completely stable at 1.295V, but to get to 4.6, I have to go all the way to 1.38, and it pushes temps to 95 Celsius...OUCH!

hi all
I'm new here
I have 3570K with scythe yasya, asrock z77 extreme6 bios 1.20, kingston 8Gb 1600MHz 1,65V
and trying to oc...
well, I'm doing everything like on this guide with some support from this guide:
http://www.overclock.net/t/1198504/sandy-ivy-bridge-complete-overclocking-guide-asrock-edition
want to reach 4,4 GHz, tried with fixed vcore 1,2V up to 1,3V
1 hour in prime with no errors, temp 75-85C defending on voltage (temp not so bad)

BUT when playing BF3 5-20min then blue screen with 0xD1 (I found that means "add QPI/VTT voltage" , but I'm afraid to touch it, don't know what will happen)

tried also 4,3GHz with 1,15-1,2V fixed but temps were about 80C (not satisfied) - BUT same thing with prime and BF3 like above)
Intel SpeedStep Tech: Enabled
Intel Turbo Boost Tech: Enabled
Turbo Boost Power Limit: Manual
Short: 500
Long: 500
Long Duration: 1
Additional Turbo Voltage: Auto
Core Current Limit: 300
Host Clock Override (BCLK): 100.0 MHz
Spread Spectrum: Disabled (tried also with enabled)
DRAM Timing Control: Manual
I've set RAM volts fixed 1,65V (auto as default)
Power Saving Mode: Disabled
PCH Voltage: Auto
CPU PLL Voltage: Auto
VTT Voltage: Auto
Enhanced Halt State (C1E): Enabled
CPU C3 State Support: Enabled
CPU C6 State Support: Enabled
Package C State Support: Auto

well I had no problems with oc-ing e8400, with ivy I can run only on default settings, but this thing supposed to be made for oc-ing, right? where's the sweet spot?

what am I doing wrong?
any suggestion?
updating bios will help?
Please help me

I am new to this site, but it seems like a very mature and helpful community. I was wonering if my temps are too high for what I'm doing. I'm running a 3570k at 4.5 right now. Vcc is at 1.24, and pll down to 1.5. My temps on my hottest core are reaching 80c on prime. Is this normal? My HS is a hyper 212+

Perfectly reasonable. During normal workloads your temps will be much better. In Almost all games I don't top 60C.... Even F@H only generates temps up to 75C or so.

Sorry for the repost if you have been following this in another forum - but this seems to be the right place for it.

Ivy Bridge 3770k, Corsair H80 Cooler, Sabertooth z77 motherboard. Using Step at 4.8 ONLY - with no other settings, I am stable. It seems I have a chip that likes overclocking, but the issue and reason I am only running it at 4.5ghz is that it peaking at 4.48v to do 4.8!. I am leaving speedstep, HT etc enabled, and have not fiddled with anything other then the stepping speed.

Any ideas on reducing the voltage ? What should I try next ?

First, big thanks to Sin for posting the guide and remaining active in responding to posts!

I've been building my own computers since the mid-late 90's and this is my first serious OC attempt and i'm reaching for 4.8Ghz. I would love 5Ghz but it is out of my reach with this chip, I've run at 5Ghz - it booted but any stressing crashed it fairly quickly and i gave up trying before hitting 1.5v. Anyway, in seeking 4.8Ghz I became 1 hour prime95 / IBT xtreem stable at 1.38v core (and ram at 1333) but i saw 2 WHEA warnings in my system log so i'm increasing voltage to overcome - even at 1.39v my temps are holding around 80 with spikes not breaking 90 (p95 running now with vCore at 1.39... and prime crashed 37m in with the settings you see below - and again 2 WHEA warnings).

I have a couple of newbie questions:
  • should I care about WHEA events even if processes don't die? I believe i should, but should I?
  • is 1.4v too high for 24/7? I've read and skimmed all 30 pages of this topic and I'm getting mixed messages but an impression that it my be too high for 24/7
  • I've toyed with the idea of lapping and (possibly) going as far as replacing the crappy IHS thermal compound *shakes fist at intel for not soldering this one* - i know these are extreme measures, what i don't know is what the practical return would be apart from building muscle tone in the arms - anyone have opinions or better yet, data on this topic for the 3770K?

And a couple of newbie learning (please confirm or dismiss)
  • After becoming VERY unstable (but still bootable) I found my BIOS settings changes were not always respected - i learned it is best to save my profile, clear the BIOS and reload my profile to improve stability as well as ensure the settings i think i have applied are actually applied.
  • once stable, I am reinstalling windows. There is no way i'm running for the next (insert time here) on an OS which was patching itself while prime was running and failing!
  • It's taking me longer than i would like to become stable. I have spent 2 solid days tuning and loading and i'm getting tired of it - i just want to use my new box but after tasting the cusp of 5Ghz i cannot go back to 4 mad.gif
  • water cooling is a lot of work, and using a kit not really that expensive (i'm in about $250 including water for mine)
  • OMG SSD's are AWSOME thumb.gif
