Ok I will try that smile.gif

I really would love to get this to 4.9ghz for 24/7

Didn't get much attention in my last post... so I'll give it another shot rolleyes.gif

Ok ppl...

I've been doing it simple. Right now I'm just going with multiplier set to 47, vcore at 1.35, LLC at 5 and adaptive mode +

Last time I tried to make som changes I just tried multiplier and my cooling solution wasn't as good as it is now and the vcore and the temps in load wasn't what I was looking for. This time I thought I'd take a look at bclk, but before I do that I'd like to hear your opinions.

If I go bclk 104 with multiplier at 46 I'd end up at 4784, cache clock of 4160 and fclk of 832. Would you recommend me to change various other things as well or can I leave SA and VCCIO untouched since they affect ram... or am I getting this wrong?

guys, I really want to OC my 6700k, but I have to say that Im quite amazed about how many comments about skylake OC can lead to chip degradation and thus get problems really soon I found...

I mean, Im pretty sure I can do 4,6ghz at 1,34v, but I dont know if its REALLY safe rolleyes.gif...anything above 1,29v scares me.

I read people using 1,3 to 1,35v and having problems after a few months (the cpu asking for more voltage already, otherwise crashing)...

I have had my 2500K at 4,4ghz and 1,38v for 4 years no problems but skylake...I dont know...

I am in no way a skylake pro as I really have only been properly working on mine for the last 9 hrs or so but I will try and give some advice (hopefully some people who are more pro can back me up or suggest other things)

I would highly recommend starting with the simplest overclocking as much as possible, find your max speeds for your determined thresholds (voltage and temp wise) and then tweak them.

This is what I have been doing.

The simplest and most stable solution for finding these perimeters is taking it in baby steps that you are comfortable with by carefully increasing your multiplier and voltage with the appropriate testing.

I am unsure of what motherboard you have, however these are the basics I would suggest.

Set your Bclk to 100, multiplier eventually to your desired achieved speed and your voltage in manual mode BELOW what your max comfortable level is and tighten the LLC. *at least on my board the LLC will over volt your cpu to compensate voltage drop under intense loads so the higher you raise this setting the more it will increase the voltage at times above your set manual cpu voltage. (more or less depending on your mobo)

Keep playing around with this until you find something very close to being stable...

Once you are almost stable is when I would suggest you move into more in depth mobo adjustments. (tweaking of Bclk, multiplier and moving over to adaptive or offset voltage regulation. (bear in mind that again your LLC effects the voltage adjustments so find that "ratio" for your particular motherboard.

Ensure you do this all with everything set to absolute stock speeds. (your gpu, ram, etc)

eventually you will find your particular cpu's sweet spot for what you are trying to achieve and can move onto making adjustments to optimize all your other speeds like ram, etc etc

(Keep in mind that despite your goal being to up Your Bclk speed right off the bat, you have a higher chance of failing a test due to other factors (such as ram speed increase beyond optimal, etc) and my way mentioned above is the simplest way of narrowing down specific issues)

Hope this helps smile.gif

I have read different recommendations everywhere. Ultimately when you take up overclocking it is what risk you are comfortable with taking. For some 1.35v will be too much, for others 1.45v doesn't even bother them.

Look up intel's recommendations and specifications. Decide how long that cpu needs to last you, and if the gains are truly needed. Ultimately in the end if something goes wrong it comes out of your pocket.

Also I would suggest this https://click.intel.com/tuningplan/

Hopefully that helps! smile.gif

oh ok sorry my bad lol.

I personally would drop my ram speeds to compensate for the automatic 40mhz increase of frequency with the increased Bclk. (just to eliminate it as a possible issue as you work on stabilizing the cpu)

I'm still learning myself, so I can only recommend what I am finding helpful! smile.gif


p.s. *30 min's to go on my prime 95 27.9 test for confirmed 3 hr stable run at 4.8ghz! WOOT!* tongue.gif

I'll validate with my crazy voltages and temps and cpuz soon smile.gif

I've read conflicting data everywhere. I am also wondering if 1.395v @ 4.625GHz is "safe" for 24/7 use as long as temps are in check? During stability testing, my highest core was 80 degrees C and average temps across all cores was 75-76 degrees C. Idle temps are good: 26-28 degrees C. While gaming, temps never go above 55 degrees C, mostly 46-55 degrees C. Sorry to keep bringing this up again, but I've been running at 1.37v for 6 months and have not noticed any degradation. TIA

Well I may not be the best person to ask.

Reason being I am going for a 24/7 overclock that far exceeds what it sounds like you would deem safe.

My max comfort level for vcore for this is 1.475ish

That said I have no intention to be still using this cpu in 3 years and i have purchased intel's protection plan if it craps out before then ( in case )

temps are key imo.

My temps will be very acceptable given in P 95 the highest temp peak i reached was 88C for a very brief moment with an average of 70 C in blend tests

Seeing how i'll only ever use this pc for gaming, it should rarely if ever get close to that.

For myself this is 100% acceptable to what I deem safe (a little above intel's max recommendation of 1.45v)

Well....Here goes.
I tried 5.0 @ 1.5v, it booted but was not stable, so I tried 4.9 @ 1.5v. Not stable either. I got to 4.801 @ 1.485v 84C, also not stable for more than 2 hours. 4.7 @ 1.46v 82C was not stable either. So meh...lol.
4.625 @ 1.395 is stable ironically.
So this is my dilemma:
4.4 @ 1.265v 58C
4.5 @ 1.280v 67C
4.6 @ 1.37v 71C
4.625 @ 1.395v 80C
I'm still under 1.4v technically, but different sites give conflicting advice. And this IS OCN for god's sake(insert random deity here). Most ppl are telling me to drop down to 4.5 @ 1.280v, but to me the increase between that and 4.625 is noticeable. I like moar powah! So yeah....I'm cornfusled. tongue.gif
