What is this VID Voltage? Vcore in 1.344 but VID core voltage go up to 1.400 why?
Explained please.

Moderator edit - This was another thread regarding Undervolting. Sorry thread continuity got screwed up a bit.

How to Undervolt i7 7700k CPU? or any CPU which one should i use for that?
Adaptive or offset?
Which settings exactly need to change for undervolting?

Explained Please?
 
You would choose a negative (-) offset and slowly work from there.
Example 0.005 to 0.010 and so on. You would do some testing like cinebench after every adjustment till system is stable.
 
With what software program are you seeing this?
The VID volltage is the cpu's default voltage (shown in the bios) when set to "auto cpu voltage" and there is no overclock and no turbo set.

Basically VID is the default voltage
Vcore is how much voltage is going to the cpu core(s)

Thanks, can you tell me for i7 7700k 4.5Ghz how much volt it needs?

HWiNFO64 v5. 72-3333
This show me
Core #0 VID 1.304
Core #1 VID 1.304
Core #2 VID 1.304
Core #3 VID 1.304

but CPU-Z show me
Core Voltage 1.248v

No Overclock i just adjust Offset (-) and 0.010 this are the results

Any idea?

You have to manually test. There is no way to know needed volts as every cpu is different.
 
I just only need to change

Core/Cache Voltage > Offset (-) > Offset Voltage 0.050

Like this right?
 
Is your vcore set to fixed or adaptive ?
 
Adaptive and Offset mode.
I never use manual mode Cause it gives max voltage for CPU, even when its idle. Do i don't like Manual Mode.
 
is your vid and vcore changing value ? How high did you set llc ?
 
If i set Adaptive mode 1.350v in bios with LLC 4 VID can Go up to 1.409v

Yes, That looks good.

Thanks but voltage seems like not right.

I can low it to 0.100mv
but when i do HWINFO64 *VID Core go up to 1.307*
but CPU-Z Core Voltage is 1.152 some time it's go to 1.168v for seconds. Any idea?

Voltage will vary with different programs. The bios itself will report voltages in the monitoring area.

cpu-z readings will fluctuate but that is normal.
 
Yeah use cpu-z core voltage.

Don't confuse yourself with other programs.
 
isn´t there a extra volt for turbo under avx?
with which program\software are you testing your cpu?
 
Thanks, i read that already, they do just basic Overclock steps, i try that, and it works but to be honest.
It's not that i need.
I have Overclock to my i7 7700k to 5Ghz but Temps and voltages not right so i don't like that, maybe i miss something.

And i try to find perfect Overclocker but i didn't find anyone.
There's no one make a perfect video for Overclocking,
what should we do when it come to Overclock, and what settings i have to change which settings exactly have to change.

bro do you know much about Overclock?

for starters im not Expert for Overclocking but. There are many people who can do better Overclocking***
And now we need their help.

***Hello Overclocking Experts***
We Need Your Help.
We need you to answer this question.

Q1 = when it comes to Overclock what setting exactly we have to change?

Q2 = What is Safe Voltage Limit?

Q3 = Adaptive, Offset, Manual Modes, which is better for Overclocking?

Q4 = When i Overclock do i have to Overclock cache ratio too? It's necessary or just optional? Can i leave it auto?

Q5 = When Overclock how can guaranteed CPU Lifespan? What can we do to change it?

# When Overclock, what is Recommend and what is Optional please tell us that too.

Overclocking Experts please give us what you know best.... Thanks*****

I Hope this Post Thread value to lot of people :)
 
every cpu or ram or +++ overclocks different
so there are only guidelines and the rest you have to test yourself.
overclocking now is easy with tools for windows -asus has a lot of them
turboV core , mem tweakit++++

it´s like i go in next computershop,buy 2x 7700k and both overclock different-have different temps,voltage,imc =how high you get your ram.

i dont know if i know much(there´s always one who know´s moarrr)-you can look me up under basco at hwbot,org

my best advise would be:
if ya dont know what this setting does leave it at auto.
only overclock one at a time - so dont overclock cache,ram,gpu,cpu all at the same time- if it fails ya dont know most of the times what failed.
 
q1 - vcore for cpu, vcsaa/vccio for memory, llc if you're experiencing vdroop
q2 - define safe. there's a difference between "if you put this much voltage it won't burn" and "this won't impact longevity"
q3 - doesn't matter, personal preference. I use XTU and have two profiles: fixed for OC (1.289v, doesn't change), adaptive for standard use (downvolts the cpu vcore and vid base on the load, up to factory stock 1.19v). Offset is great when you have some specific use for it, I currently don't. It's good when you experience instability in idle or under light load,which happens, or when you want to downvolt your cpu.
q4 you can oc cache but don't need to, it won't boost real performance, only synthetic benchmarks, mostly those meory bandwidth based.
q5 what ?

I ain't no expert tho, those are just some very basic things I learnt.

First piece of advice I'd wanna give you is to go easy on oc if you're new to this. Seriously. If you have a fairly new CPU like 7700K,8600K or 8700k, you really don't need to do much. They're so fast out of the box that I'd really let the factory boost do the work. Only thing I'd do is just to set the multiplier for 4/6 cores active (full load) the same as the multiplier for single core load. You might not even need any vcore change for that, and it's enough of an oc. Some people push for 5GHz, why ? It's striving for something only marginally faster.

Second of all, you don't have to use p95 or any stress test no matter how many people will barge in and tell you that you do.

I Have a Problem, Please Explain this?

INFO:
I7 7700K.
Corsair V-LED 8GBx4 3200MHz
ASUS STRIX Z270F Gaming

OVERCLOCK Settings.

XMP: Enabled
Asus Multicore Enhancement: Disabled
Core Ratio: Sync All Cores
Core Ratio Limit: 50 (5Ghz)
Core Cache Ratio Min: Auto
Core Cache Ratio Max: 47 (4.7GHz)
CPU LLC: Level 4
CPU Currunt Capability: 140%
VRM Spread Spectrum: Disabled
CPU Power Phase Control: Extreme
AI AC Load Line: 0.01
AI DC Load Line: 0.01
Core/Cache Voltage
Adaptive Mode: 1.390v

This are my 5Ghz setting
but when i stress testing it
CPU-Z show me most time 1.392v,
Some times 1408v, for seconds 1.424v
and VID Core go Up to 1.450v

Whats Wrong with this? Please tell me anyone?

so it's 1.392v-1.424v. Nothing too much out of the ordinary. Mine runs at 1.296v but will jump to 1.308v-1.30v every now and then.
This happens, you may wanna go with lower llc and lower power phase control. seriously, you don't need extreme power phase control. try setting this to high and report back. then try a lower llc.
 
i think its a mix from adaptive mode=1,390v plus the cpu current =140% plus what cucker tarlson said

you really need to know+understand basic´s of overclocking.

you changed some settings which we maybe dont know and ask us what is wrong?

and you should really fill out system specs in your profile-plz
 
Different board will behave differently in different modes. I think you're fine with adaptive mode for yours but I'd stay at 4.7Ghz and lower vcore, in the 1.3-13.5v range maybe. Just set power phase to default, I don't know what this does on your mobo and neither do you, no need to touch it unless you know you need it. It might set vrin voltage to aggresively or cause vcore spikes, it might as well not, but I'm certain you don't need it that high.
