it doesn't give additional voltage only when using adaptive in a stress test but regular use and for gaming or other things it just stays at the given voltage without exceeding it.

To clarify here is what I'm thinking:

 

Adaptive mode on synthetic stress test = Ridiculous voltage overdraw

Adaptive mode on normal load = Hwinfo reads a Vcore higher than VID. But this applies to manual voltage as well, and the extra bump is relatively small.

This is what I think both of you know, you're just saying it in a way that confuses the other person.

Sure. To put it in more exact terms: adaptive mode on normal load has the potential to also raise Vcore by ~.1v ... BUT ... normal load might mean either no AVX instructions or small bursts of them (depending on software) thereby making either no voltage increase encountered or for such a short period of time it's not as concerning in a practical sense.

I think my chip hates me, I need 1.35v to get it stable at 4.5 Ghz and anything above 4.6 needs like 1.5 volts to boot to OS frown.gif

I just mean it extrapolates (or something) a VID to use when overclocked. I don't know where it is getting it, but I doubt Intel programs a VID for 5.0GHz into all their chips. Which raises the question, where does the VID come from, how many entries are there for it, and is there a way to read them all out? Or is it dynamically generated somehow (and does that differ with Haswell because it has a IVR).

I'd like a bequiet Dark Rock Pro 2 if I could find one and it fit. I'd like to hit 4.5ghz.

Thanks,

Anyone? My post was already buried several pages back.

When extracted as in, errors in extraction, or errors in running the file after extraction, and what 39?

Can you be more specific? Forceman knows the fix if there is an issue. But that's some hassle.

ive downloaded the file twice already this gives me the error

Looks like an extraction error. Old version of WinRAR? Maybe download 7zip and try that?

I got the actual x264 HD bench from the source website, so I only got the loop bat file from this thread. Maybe just go to the source website then?

As for running the bench itself without errors, you basically need to run it from an Admin-elevated command prompt; yes that means finding it manually through command line too haha. If you want to make it simpler, just rename the loop bat file "loop.bat" and rename the entire x264 HD Bench folder "x264" or whatever you want.

There's a couple other things you need to do - the instructions are contained in the test folder.

All in all, the process is seriously ham-handed lol, but once you have it setup it's not bad.

Yeah, I've been doing some reading, I think I can streamline it tonight.
