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
To set DVID on your OC you need to first set your VCore to normal and reboot back into the BIOS, then go back and use that normal VID that is listed as your stock vcore as a base, and add the DVID offset to it.
Also are you enabling LLC? that is a huge deal.
Also all chips are NOT created equal, this is something people forgot with sandy bridge as those CPUs generally all did 4.8ghz, but Ivy bridge is totally all over the place, it is like normal silicon, so just you get what you get, you can always try to get another CPU.
what motherboard do you have? i can send you a profile if you have a GB Z77 board, and all you gotta do is load the profile and you have an OC, you will of course want to lower the vcore.

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 Duration: 1
Additional Turbo Voltage: Auto
Core Current Limit: 300
Host Clock Override (BCLK): 100.0 MHz
Spread Spectrum: Disabled (tried also with enabled)

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
Try updating the BIOS and try lowering the CPU PLL voltage to 1.65 or 1.6v. Also if you aren't heavily OCing your memory you can try to take down those voltages and disable the iGPU.

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 ?
Nice job man, how long did you run prime95? your screenshot just shows that you just started it.

Waiting for H100.
Yea you definitely need some good cooling hahahahaha. Good job tho!

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
- 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
WHEA-Logger Warning:
Code:
A corrected hardware error has occurred.
Reported by component: Processor Core
Error Source: Corrected Machine Check
Error Type: Internal parity error
Processor ID: 1
- should I care about WHEA events even if processes don't die? I believe i should, but should I? (You probably should, but it doesn't always matter, there are always errors)
- 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 (if you plan on keeping the CPu at 1.4v then you should keep your temperature below 80C full load. I personally think you will be okay at 1.4v and below 80C full load with P95 or IBT(so that your average top temp is like 70C))
- 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? (TIM replacement will help a few C on air, but you will totally void your warranty, and of course you can't qualify for broken CPU replacement Intel is now offering, it is not much, but if you degrade your CPU or kill it from excessive OC and there is no physical damage, they will replace it for $25 no questions asked. http://click.intel.com/tuningplan/)

In my opinion OCing heavily has the ability to corrupt your BIOS(that is why GB has dual BIOS), and memory OCing especially can corrupt the OS installation. i have never had an OS get corrupted from CPU multiplier OC alone, only BCLK and/or memory OC, as I guess data gets messed up really bad with the memory. I always think it is a good idea to re-install your OS if you have any concerns, and SSDs are awesome for that. My windows 7 install takes less than 30minutes, and it guarantees that I am not BSODing because of a corrupt OS.
You can try disabling the iGPU, you can try lowering CPu PLL more(but watch out b/c lowering it too much can cause instability). Also are you aware you have power savings turned on? If you turn them off, are you able to use lower vcore??? Also try lower LLC(turbo) and see if you are still stable.
Otherwise, like i said in the OC guide, if you lower the temperature by a few degrees, you will do more good. However you can just get a new CPU for $25 after this one gets hurt, that is if this one gets hurt. I personally think you are fine going up to 80C+ if you are planning to use that protection plan, no more do OCers have to worry about Intel not fulfilling their end of the bargain, however it will cost you a few extra dollars, but is much better than $300 for a new CPU.

This configuration also passed IBT 'very high' xtreeme 10 run test in 914.56 seconds and all of this with no WHEA events. I think i'll take the system for a spin running graphics benches and real software for a while and see how she feels.
Nice job man! You can lower that PLL a bit more too i think, even perhaps try lowering the VTT and IMC voltages a bit more, i think you will be okay with that. 4.7ghz is much better than most however! Be proud!
Okay so novice OCers: I can't post in this thread every hour, so if you have an issue or question that is extremely urgent, you can PM me, and i do return my PMs very often. However please remember I do have a life(and no it doesn't consist of overclocking all day and thinking of how to improve motherboards lol), so please don't spam my inbox. Also please fill out your rig information if you are new to this forum, it is extremely helpful for us to give you advice.
