Haswell Overclocking Guide [With Statistics] - Page 1121

post #11201 of 19540
I think we’re trolling a bit with these non OC related things.

I would like to know how to use avisynth in relation to x264 without the need to actually install avisynth (like megui does)
There’s a wealth of “thigs” to do with it.
About skype, i never used that..., i had to google it to see what you meant with the add me thing (i didn’t knew it actually has an accounts system or messaging and sharing...)

...but i'm a little concerned now with this that results may no longer reflect actual encoding performance (stuff i would do before was like.. 1080p @med, crf18 - or 720p@veryslow, for example, without changing other settings because i did not understand them)
If you are talking about the end fps result and it relation to actual encoding you do for yourself, it doesn’t! These settings are relevant in a stress test type of situation, they don’t make much sens in regular encode. They’re overdone.

As MaKe OuT mentioned, VID is the setting you set for core voltage in BIOS. Vcore is the actual observed core voltage. VID never changes. Vcore could be .016v at idle, it could be 1.3v at load. Typically it seems that Vcore on Z87 will increase .02v or .03v above what is set in BIOS (VID) at load.

On my Asus board I can set VID one of three ways:

1) Manual
2) Adaptive
3) Offset

I use Manual and my Vcore AND frequency drops at idle (I have EIST and all C-States enabled). I'm guessing Gigabyte does something differently. I will let some of the Gigabyte experts weigh in on how you should set your VID so Vcore drops down at idle.

With offset and adaptive, VID is not what you set in the BIOS. The VID applied in that case varies with load and frequency is defined by Intel. What you set in the BIOS is the offset, which is applied to this variable VID. In adaptive you can also affect the VID with the Turbo voltage setting.

At least that is my understanding of it all.

I believe that Offset mode uses a predefined VID table. So it's not good for overclocking. So yea in Offset mode the VID will actually change. Also your offset will always add to the VID so your voltage will always be higher than what it would be under Manual if you're using positive offsets. (I could be totally wrong.)

I think you're right with Adaptive as well, VID changes, but you get the voltage spikes etc.

So I use Manual where VID never changes, just Vcore.

Thank you for pointing that out. +Rep.

I think offset is fine for non-extreme overclocking, it is just that the offset also applies at idle, which is sometimes not desirable or stable.

Pre-Haswell, with offset the VID would never be higher than manual like you suggest, since you would set the offset so at load it would be equal to what you would set in manual at load. The rest of the time, when not under load, it would be less than the manual. So it will always be less than manual. With Haswell, depending on how you set the offset, it may be higher than what you would run manual with AVX load because of the boost the processor applies with AVX load when using offset or adaptive. But that depends on how you set it up. Also, depending on how you set the offset, you could end up with too low a voltage at lower loads or idle resulting in instabilities.

Be careful with your terminology, it can be tricky. You can't set or change the VID, that comes from a table programmed into each individual CPU by Intel. All you are changing in the BIOS is the Vcore, or the offset that is applied to the VID. Even in manual mode you aren't setting the actual VID, although I guess you could argue that you are overriding the CPU VID, which is why it shows that way in the monitoring programs, but the CPU itself is still going to have a VID that may be different from what you set.

Adaptive is different, and apparently works different in different boards, where you are supposedly using the auto VID at stock speeds and then an offset at overclocked speeds. But I don't know that it actually works that way in practice - seems more like the boards just set whatever they want.

That's what I meant. You can't change Intel's VID table, but you can change (override) VID with Manual mode.

Even after reading so much about Haswell I feel like there's a lot more to know.

Thanks for the input, it's good stuff.

looking at cpuz, coretemp, and HWmonitor all say same. not sure how to check vcore to see if its throttling down on idle. my frequency does and package wattage hits somewhere around 12w i think

I think that HWMonitor probably has Vcore, but get HWInfo. HWInfo has VID and Vcore listed under sensors.

So reading this I thought it more than reasonable, versus searching all night, just to ask from the people who OC everyday. Not trying to sound like a jerk, but giving a simple emoticon response is rude, and against the ToS. We should all be understanding and welcoming to nooobs, instead of conveying such a response.


That being said so far my OC stands as 4.5GHz @ 1.325v Uncore at stock. We shall see if it lasts.

All he did was post a funny emoticon. Nobody went off on you telling you to shut up or anything, so I don't think anybody was really out of line. 

 

As a suggestion, ctrl+F searching "safe" would save you time next time by jumping you straight into what you're looking for. Had you been unable to find the safe vcore/temp values even after I responded I would have copied and pasted parts of the guide to you for reference. Let's move on and save it until some person really becomes antagonizing on purpose. Until then this is just a minor misunderstanding.

 

And yes, let's see if your OC lasts.

Well it was not helpful.....so therefor shouldn't have been posted. Spouting simply "search" for it is irrelevant, I asked people directly in a thread designed for it, so either way I did nothing wrong either. Maybe its because i'm from an older generation that I have the mindset if you don't have something helpful to contribute don't bother replying.

Point is moot now, as some great people have been responding and helping me out tons.

Back on-topic I have downloaded HWinfo and think i have found the vcore (I miss my Ivy was so easy just a year ago. lol) it does look like it is in fact throttling down from fixed voltage. Thanks and plus rep gents.

Now onto fine tuning. biggrin.gif
