Adaptive Mode

[gramzon]

I've just found a stable overclock for my system with 1.3v at 4.7ghz. Now when I change the voltage from 1.3 to adaptive the voltage drops? When I run aida64 stress test and CPUz I can see that the cpu is still at 4.7ghz but only receiving 1.25v isn't this the stock voltage and why isn't my 1.3v saving?

 

Edit: I've used Linus's devils canyon and also haswell overclocking guide for this but didn't see it mention anything about this issue.

With Adaptive Mode, your CPU is only going to get as much voltage as it needs, so if it runs at 1.25V, then it's stable at 1.25V, but be careful, you shouldn't use Stress Test applications like Aida64 or Prime95 if you have Adaptive Mode on, because your voltage can go too high in some cases and the CPU is going to get too hot.

So when I run the stress test with adaptive on my CPU uses 1.252v that means this is what it requires? but with this v it blue screens. I've run 24 hour stress test twice with 1.3v manual and it's been fine and I've also been using it while on manual for a couple of weeks. What could be the issue here?

 

Also what does the 0.05 offset volate do? and what is it for?

 

Btw thanks for the quick reply

0.05 voltage offset means that your voltage is going to be 0.05V above the stock voltage.

If Adaptive Mode sets your CPU to 1.252V and it's stable, then yes, that is what your CPU requires, and you can just generally leave Adaptive Mode on just because of the fact that it's much easier, and if your CPU becomes a little bit unstable after some time (CPUs tend to lose some performance after some time, so you would probably have to add a little bit more voltage to your CPU after a few months in order for it to still be stable), you more likely won't have to deal with blue screens and time consuming stuff.

 

Manual Mode for voltage, from what I know, isn't really good, because even at idle, it will stay at the voltage that you set in the BIOS, so your CPU will consume more power, even if it doesn't do anything (don't quote me on that one).

I still recommend going with Adaptive Mode, but just keep in mind, you shouldn't run stress tests when you have adaptive mode on, because those programs, as I said, can override the voltage of the CPU, to a point where the CPU cooler won't be able to deal with all that heat.

Hmm I understand, so in this case shouldn't my offset voltage be 0.5 rather than 0.05 like in Linus's video? because that will allow it to go up to 1.3v rather than just 1.25v. With adaptive and stress test I haven't had any issues with heat, its just that I think it isn't getting enough V so it's crashing since with manual below 1.3v it was not stable, which is why I don't understand why the computer isn't drawing 1.3v at adaptive

Well, I think that you put a little bit too high offset voltage right at the beginning (+0.5). Usually, when you overclock, you raise the voltage just little by little, to see what's the lowest voltage that you can get without the PC crashing because of the CPU.

 

So yeah, when you set Adaptive Mode, it's not running at 1.3V because it can be stable at lower voltage.

 

I hope I've helped you, if you have any more questions, just leave them here

could there be a settings somewhere that I haven't enabled and that's why it isn't pulling more than 1.252v. It is blue screening on this voltage.....

[Mateyyy]

Is it blue screening when you set 1.252V on Manual Mode?

Can you post a screenshot of CPU-Z when you have Adaptive Mode on and the CPU is under load?

Yes at 1.252v manual it blue screens, I have attached image with adaptive mode on with load.

Well, I have to say that I'm not really sure why that voltage doesn't work on Manual Mode, but as long as Adaptive Mode works, I think that you should stick to it...

 

btw: awesome rig

Thanks! but the adaptive mode also crashes, that's the problem. So either I stick with manual or not overclock

Ooooh... Ok, then, just stick to Offset Mode, and set the offset to +0.5V, like what you said you had before. That's stable, as you said (it better be at 1.3V), and as long as temperatures are good, there's nothing to worry about.
