HELP!...OverClocking i7-2700K to Intel DZ77GA-70K Mobo

post #1 of 6
Thread Starter 
Greetings!... Just a Newbie in OC'ing so i needed an Experts advice before i make any Bios-changes in my new PC, aiming to get the best OC-values and longevity life of my unit as well

The following is my CPU-Specs so any suggestions are welcome and are greatly appreciated:

Mobo - Intel DZ77GA-70K EXTREME *LGA1155 *Sandy Bridge
Procs - i7 2700K@3.5GHz
Aircool - Thermaltake Contac 39 [3Heatpipes/Dual Fans]
Mems - Corsair Vengeance 4x8Gbs@1600Mhz
VC - XFX AMD Radeon HD 6670 2GB *DDR3 *PCI-Ex 2.1
PSU - CoolerMaster 700w

Thanks in advance Sirs!!! smile.gif

You can refer to this thread for a quick guide on how to overclock. It's mainly for AsRock boards but it's the same concept. smile.gif

THANKS MASTERS FOR YOUR INFOS & ADVICES smile.gif .. to which only just now I cud reply again from lots of OC-Googlings biggrin.gif

> As a Total OC-NooB and result of my eagerness & curiosity..
I downloaded and tested my CPU from the Default 3.9Ghz Turbo mode upto 4.3Ghz *using only the Visual Bios Tweaker (Trying 2b Safe*lol) using the following tools:

*IntelBurn TestV2 (Using Standard Stress/64bit/All Threads/10XRun)
*RealTemp 3.7
*CPU-Z 1.62
*Still not used the Prime95 27.7 yet

> Purpose of Trying to get the OCmax zone using my Intel AutoOC... Results are:
#1. Load/Save/Exit/Start from Default upto 4.3Ghz Auto Tweak = encountered no errors as per IntelBurn Test
#2. Auto-Setting again to 4.4Ghz = Warning Critical Level Reached on 88*C started on the 5th Run of IntelBurn so I just Stopped it:
Stress Level: Standard (1024 MB)
Testing started on 11/13/2012 7:48:55 PM

Testing ended on 11/13/2012 7:50:21 PM
Test Result: Stopped by user.

#3.Now I have reverted back to 4.3 and decided to ASK AGAIN YOUR ADVICES... So kindly help me reach the 4.5... if i can?

Also: on the following Pictures THIS I TRIED *hoping it will be clear enough to show my status:



My QueStioN:
> Are the ABOVE SETTINGS be really acceptable for my 4.4 going to 4.5 mark in Manual OC starting from 1.300v to 1.325v limit? If not PLEASE tell me exactly what to do from this point. bulb.gif

MY SETTINGS:
+ Started Fresh from Default 3.9 Settings
+ Ports & Features not in use = DISABLED
+ EIST on PERFORMANCE (If Disabled = Turbo is also Disabled)
+ IPLL = ENABLED
+ C2E and C3E = DISABLED(There is no C1E on my Power Settings)
+ MEMORY = XMP FUNCTION (I Checked and its in the same timings with Actual Manufacturer Specs: 10-10-10-27)
+ VIDEO = DEFAULTS (not changed any settings)
*PLEASE SEE PICS & RESULTS of the Above Settings (Saved as file only in Bios for further testing)

+ For this Settings i got this results:
IntelBurnTest v2.54

Test Result: Success.

> AddtL QueStionS:
*** Is VCORE is ---> PROCESSOR I/O (V)?...then what is that PCH Core (V)?...Will it be SET on the Same Value?
*** On the CPU-Z results *Above Picture, WHY is the CORE SPEED not appearing same on my OC FREQUENCY? Always in Opening its on the above 4Ghz then suddenly it will go down on that same figures fluctuating??? ph34r-smiley.gif

AGAIN MANY THANKS IN ADVANCE SIRS AND I WILL POST THE RESULTS AFTERWARDS !!!...

Any reason you made two threads for this? I posted in your other thread:

First off, it is normal for the CPU to clock down to 1.6 when it is idle - that is the powersaving features kicking in, so don't worry about that. However, it is always best to take your CPU-Z screenshots while the CPU is still under load, since that'll show the OC frequency, and more improtantly, the voltage.

Second, 1.30V is probably not going to be enough for 4.5 - I would expect something closer to 1.35 for that speed. Anything under 1.4V is plenty safe, so don't worry if you need to bump the voltage a little bit to get it stable - just watch the temps. I don't know why they are calling the Vcore the Processor I/O (V) - assuming that's what that is - but you can easily check to see if that is really Vcore by comparing what you set there to what CPU-z shows under load.

Third, the PCH voltage is for the Platform Controller Hub, what used to be the south bridge, that controls the peripherals like USB. You can leave that voltage alone.

Finally, you can disable the Intenel PLL Overvoltage (I think it was called override in your screenshot) - it is nornally only needed above 4.6 or so.

You are also probably going to want to change the setting for Load Line Calibration (Vdroop control) to something in the middle of the range - that'll help keep your Vcore stable under load. You might also want to bump up those two power limit sliders (the ones in Watts) so your system doesn't end up power throttling.

So sorry if made 2 threads for this *due to Forums Titles relevances only! smile.gif ... So i I will just be using this Thread from now on!

Many Thanks also for your reply Sir "Forceman" and I will apply all of these details later on <--- presently at work tongue.gif

* Regarding on your reply, Im assuming basically all my Settings are correct then...?
* "Second, 1.30V is probably not going to be enough for 4.5"... That values are on 4.4 but still with IntelBurn Success results it is, still not reached 4.5 > the next option there is 1.325v then 1.35v...will I still go beyond that? btw how will I know if the voltage is enough & correct even if with Success Results?
* Any suggestions on the Wattage Value adjustment?
* So from this Settings, How will I Step-up going to my Maxed Stable OC?... The add-minus thing?
* How in Prime95 or IntelBurn can i know I have achieved my OC-Stability >> "Test Result: Success" without Warning Errors *is it enough?
* Vcore the Processor I/O (V) - assuming that's what that is - but you can easily check to see if that is really Vcore by comparing what you set there to what CPU-z shows under load. <--- FIRST THING I will check later on!

Thanks Again Sir!!!...

Everything looks okay in the settings, the stuff I mentioned is just some stuff that can be changed if you want. But nothing looked out of place.

Yes, 1.325V or 1.35V is fine for the 2700K, and you'll probably need something closer to 1.35V to get 4.5 stable. But that really varies by chip.

I don't know what the range is on the wattage value - you can leave it alone if you want and then only change it if you run into problems (where the CPU clocks down for no apparent reason), or you can try setting it to something in the middle of the slider. The chip is unlikely to overdraw the motherboard at any reasonable overclock (probably anything under 5.0 - but again it depends on voltage), so you can probably safely set it to whatever you want.

Once you get it stable at 4.4, then you can change the multiplier to 45 and try again, and then up the voltage if you need to. Keep doing that until it hits a wall (where it doesn't want to go any higher no matter what voltage), or you get to a voltage you aren't comfortable with (I wouldn't go over 1.4V long-term although lots of guys do - that's just me), or the temps get too high (something in the 70s under Prime95 load is fine).

If you can run 10 passes of IBT at Very High or higher, then I'd say that was stable enough to start using - if you notice crashes in games or something then you'd want to go back and do some more testing. Likewise for Prime95 - about 8 hours is enough. A lot of guys do 24 hours of Prime, but I personally think 8 is enough - opinions vary on that though. My thinking is that I'm not running a nuclear reactor here, so an occasional error that doesn't cause a crash is acceptable, and I've found 8 hours to be enough for that level of stability. You'll know it passes IBT because it'll give you the success message (and your system won't BSOD) and Prime95 will report errors and stop the worker thread so that's easy to see also.
