Turbo boost overclocking.

ATi RaDEoN · Jul 1, 2015

For some reason I can't increase base CPU clock on my mobo so I increased the turbo boost multiplier of all the cores to 42 and the resulting frequency was 4.2 GHZ. My PC usually hits 4.2 GHZ as soon as the turbo boost cuts in, rest it idles at 1.6 GHZ.
Is this type of overclocking considered good?
I have also not done any changes to any of the voltage tab, I have seen the max voltage of my CPU as 1.26V. I don't know whether it is safe or not, so please anyone tell me.
I am seeing improvement in games and temperatures are 65-70 degree celsius under gaming load.
CPU: i7 2600k
Mobo: Intel DZ68BC
GPU: GTX 960 4gb

Interesting user name being you have a GTX 960 lol.

As for using the turbo boost to do your overclocking, yes it will work, but its strange that you can't change your base clock. Did you try to turn turbo off first? That should enable it.

If you do run it this way you may run into voltage issues at heavy loads, as well the performance will be inconsistent. You can test this using a stress test program to see if it really holds up. That said I would figure out why its not working right in the first place and use the standard multiplier to get consistent performance.

I tried everything
base clock won't go past 34. Although I can decrease the base clock.

This is how my BIOS performance menu looks, all options greyed out except processor overrides, memory override etc.:

On going to processor overrides, I get this screen. On the bottom I have set the core ratio limit to 42. On the top, maximum non turbo ration won't go past 34.

(PS: When I created my account 5 years back, I used to own an ATI radeon)

On that second one did you try to disable "Intel Turbo Boost Technology"? That should unlock your ability to incrase the max non-turbo ratio.

I did that, no success.
However on the first pic, if I set the overclocking assistant to automatic, it lets me overclock to a maximum of 4.5 GHZ and there is only one option shown to do this, no voltage or any other thing required. I have set it to 4.2 GHZ, seems to work fine for now. What say?

I wouldn't go to 4.5ghz on automatic settings but 4.2 seems safe. I did some research on it and others have had similar issues with this BIOS and getting it to behave on overclocking, but many mentioned success with the auto mode. Try some stability tests see how it goes and let me know.

In both the modes. automatc and manual, CPU looks stable and I am playing Prepar3d much smoother than before. But one thing that caught my eyes was CPU Vcc monitor on speed fan. In both the cases (automatic and manual, no change in any voltage or whatsoever) when CPU hits 4.2 GHZ, it reads 1.46 V. While idling it reads 0.94V. I think it is in danger zone.

ATi RaDEoN :

1.46 is high, I mean it will work but you're hammering on the CPU and it could cause long term stability issues. You really want to max out just under 1.4 tops. This is the issue with the Automatic mode (or automatic modes in general).

I have continued to do some research and the problem you have with this board is common and with no solution. Most folks just go with using turbo mode to overclock. It seems to work fine, assuming you can get the voltages where you want them, Form your first post you said it only hits 1.26 using that method? Or am I wrong.

1.26 was when using prime95 and at that time frequence was 3.7 or or something. On hitting 4.2, things worsen. I din't notice that before. Looks like I have to manually set the voltage.

Yes use turbo to do that and keep your voltage at 1.39 tops. There are people that have gone to 4.5 ghz and more with your combo like this.

Just keep in mind as well every chip is a little bit different so in the same respect it may not hold up on OC as well as someone elses.

ATi RaDEoN · Jul 1, 2015

The problem is that even when using turbo, CPU hits 1.46V, I can't figure out where to disable auto voltage control. Turbo oc and auto oc seem to be doing same task.

ATi RaDEoN :

On that first screen where it has voltage overrides Processor Core Dynamic, can you change that?

ATi RaDEoN · Jul 1, 2015

Rogue Leader :

No, I can't change that. On the second screen, I can change processor voltage override type to either static or dynamic. Static brings voltage ranging from 1.00 V to 1.9 or something while dynamic brings CPU offset menu with small values like 0.05, 0.1 etc.
Don't know what to do.

Thats what you want, Static and set it to 1.39

ATi RaDEoN · Jul 1, 2015

Something looks seriously wrong. I reset my BIOS and again set the turbo multiplier to 42 and this time max CPU VCC voltage was 1.27 V(checked using CPU-Z and Speed fan) and games running fluid.
Looks like motherboard is faulty.
Anyways, thanks for helping me, you can surely add anything to this topic if you feel it is important.

That is strange. Its possible its faulty, a lot of the talk about this board was about oddities (like this) when overclocking. Generally Intel boards are rock solid for standard use but when it comes to tweaking you want to go with an ASUS or the like.

I don't know that your mobo is faulty, but it is possible. Did anything else change? Also do you have the newest BIOS?

Yes, I have the newest BIOS. But for now, CPU seems to be running pretty stable at 4.2 GHZ at VCC voltage of 1.27 V. Strange but true.

Glad it worked out. At that voltage if you're game you can try turning it up more. But if you're happy and want to stop messing with it, trust me I understand. Its how most of my overclocking projects end "this is good enough!"

I hope so it goes fine. Thanks for helping me out...someone said it right....overclocking either ruins your processor or ruins your day...it was the other way around for me !
