4670k Overclocking Help

Go to solution Solved by Faceman,

Hi Guys,

 

I have been trying to overclock my 4670K, and I think my voltages are too high, for the overclock I am running. In Linus's video he recommended starting out at a 4.6 Ghz OC with 1.2V.

 

I have to push 1.27 Volts for a 4.2 GHz OC.  I under-clocked my RAM to 1600Mhz. And changed no other settings. 

 

I am running a 4670K on a MSI Z87-GD45 Motherboard with a H90 cooler. I run anywhere from 35-40C idle

You have to go into overclocking with an open mind, every chip is unique.  Focus on getting the absolute best result for your chip, don't try to replicate or compare your results to others.  Start low and work your way up using a guide.  Make sure that you have adequate cooling(which you do), and whenever you are stress testing, set your voltage to MANUAL.  When you are not stress testing, then you can revert back to adaptive.  Try and keep temperatures below 85C. 

 

Here are a few guides:

Asus Overclocking Terminology, Key, and Explanations I see that you are using an MSI motherboard, so you will have to figure out what setting on Asus correlates to what setting on MSI, shouldn't be too difficult

Overclocker's.net Haswell Overclocking Guide(With Statistics) A very nice and comprehensive guide, does some explanation of what different settings and how they impact your OC.  With Haswell, don't even play with Uncore/Cache, it has zero impact on performance and causes a lot of instability.  Leave it at stock, with stock voltage.  Core is king.

Linus Tech Tips Haswell Overclocking Guide A favorite of mine, this really helped me learn how to overclock with Haswell, and you can always post in that section asking for help.

Load Line Calibration and Overclocking An often overlooked aspect of overclocking, good idea to read up on it so you at least understand what this setting does.

 

Take your time, don't rush it.  Could be that you have a bad chip, and no amount of cooling can help you.  Be patient, test your overclocks thoroughly, make sure you use manual voltage when stress testing, and have fun with it.

Unfortunately I don't think so. When I started I tried 4.4 at 1.25V which failed immediate on boot. So I put 4.2 at 1.25 which failed some. I bumped the voltage to 1.27 and it was stable throughout an 8 hour stress test. I used MSI extreme tuning utility.

I just don't want to push it to 1.3. Is 1.3 a definite damage threshold? Or is it just where heat tends to go over the top?

Just monitor temps using RealTempGT. Anything under 1.4v is fine for daily usage.

So really as long as I stay somewhat below the TJ max? So 80-ish?

TJ Max on Haswell is 105C. But you want to stay under 85C for stress tests and daily usage.

So far The highest clock I can get stable it 4.3 at 1.3V I averaged about 72 Degrees. Should I be happy with that?

 

EDIT: That is 72 Degrees under Full Load

In order for someone to know that you have responded, you need to quote or "@" them.

 

Your temperatures are good, but your Ghz to Voltage is not...  Are you leaving cache/uncore at stock?  Set Cache or Uncore to 38 min and 38max(at least thats what I did with my i5-4670k) leave voltage on auto.  Make sure you have enabled XMP for your RAM.

Sorry for the late response. I left the cache stock, and had left my ram at 1600 mHz just to make sure it wasn't a ram problem and eliminate a debugging variable. MSI's overclocking genie is dreadful it will only overclock my chip to 4GHZ so only 100mhz at 1.25V I might should just leave my chip as it is and pick up a devils canyon in a year or two.

I would rework your way through those guides I posted.  Use the BIOS, don't use the auto-OC Genie.

Should I avoid software based OC programs like MSI's Extreme Tuning Utility?

Yes, everything should be done in the BIOS.  Go to youtube, type in your motherboard + i5-4670k and watch some guides, start learning.
