[6820HK | 6700HQ] CPU Voltages at Idle and Max. (Stock + OC)

I'm mainly curious about the Max Power Draw when you're OC'ed.

My 6820HK voltage seems to be up there when OC'ed at 4.0GHz. Anyone else?

To keep it organized, please copy paste below and use the following format.

* I know the idle numbers can be all over the place and fluctuate frequently, therefore, please just add a ball park figure. An average is fine. As for the OC'ed Max value, that should be easy since you can just read that from the Max column.

As we're running the same OC I'll post mine when I get home from work.

 

CPU: 6820HK
PSU: 240W
Software: HWiNFO64

Stock
Clock: Default
V at Idle: 1.181V
V at Max: 1.244V

OC'ed
Over Clocked: 3.9x
V at Idle: 1.168V
V at Max: 1.223V

 

Are you using an overvolt for your CPU ? Never reached that 1.339V except when i did a mistake in XTU and overvolted instead of undervolting

 

Yeah that is high, I don't even run my desktop that high!

 

I have also wondered about this voltage thing. Even on stock as that is what I choose to run on a daily setting my voltage hits 1.243 which I thought was high. That's what worries me about overclocking.

 

That 1.339V @ 4.0 is stock! That's what compelled me to create this thread because when I saw that I was SMH haha.

So guys, technically at 1.339V stock, that should be enough juice to fuel a nice OC without changing any voltage settings ya?

When I run 4.2 or 4.3 I set the core voltage to 1350 in BIOS. That's 1.350V...but changing that in BIOS does some funky things....just odd..

Are you able to lower it to 1.300V?

1.339^2 / 1.300^2 = 1.0609x more power over 1.300
Which is still 17% higher than stock 6700k's default

 

I haven't tried to UV when running at 4.0x, but I'll give it a shot.

 

At least what i can conclude from your temps Vs. Voltage is that you made an AMAZING repaste job mate. Even using CLU at 3.9x with my voltages gets CPU temps to 71C at boot (of course it idles in the 40s after that but still).

To give you an idea i usually UV at:
Stock CPU: -123mv
OC (3.9): -45mV

 

Thanks mate. I do have extreme OCD which I'm sure had contributed

I take it those are your UV on the cores? Did you also UV the cache? Using Throttle Stop?

I was able to achieve -200mv on the core and -65mv on the cache when OC'ed to 3.6x (my version of AW's default, not theirs haha) ... as 3.6x is the stock max boost so this is my Eco mode settings...runs darn cool and well. ...

I just UV on the Core Voltage offset in XTU, the same UV is automatically replicated into the cache voltage offset.
With my Settings the voltage goes down as low as 0.9V at stock speeds and never exceeds 1.99V at 3.9x (which is my daily setup).

The thing is i had to do many trials to get something stable. Sometimes the UV works well through extreme benchmarks but ends up freezing unpredictably during a youtube video. Everytime it happens i lower core voltage a bit again and that got me to a completely stable system without any freezes.

 

Very nice.

Oh and just to clarify, did you make a typo with the 1.99V?

Isn't it strange to get the random freezes with the smallest of things? I would game for hours during my trial and error phase of finding the sweet spot then bam...it freezes on the lightest of things. Just crazy...

Yeah, typo. Maxed at 1.199 (the values that i showed earlier were without UV)

I suspect the instant shift from idle CPU to high speed to be causing the freezes on things as simple as youtube videos but its to be confirmed.

 

It's a big difference between 1.99 vs 1.099V
Freezes with light load is a sign that you applied little too low voltage. 1.250V is good for up to 4.6 GHz with an ok silicon. After this level wouldn't voltage scale up equal as you up your multi.

 

Yeah you're right, my apologies, we are talking about 1.199V max . Good thing i attached a screenie.

 

You need LN2 to cool a 300W processor ( 2.00v+ )

 

I see clear signs that i7 BGA is worse binned processors than 6700K. Virtually all 6820Hk should managed 4.2 / 4.3 GHz with max 1.23V or less. @iunlock @slayer2333 You should try 1.230V or less with 4.3 GHz on your 6820Hk in Wprime 1024M stress test. Test also with CB R11.5

 

As mentioned earlier, putting a heavy load on the CPU with Cinebench, Wprime, 3DMark with a higher UV doesn't cause any freeze (i believe that's when the CPU needs the most juice), but the random and light tasks (that are supposed to take less than 5% of the CPU power) are sometimes causing the freeze

 

I know. You and other with 6820Hk should try what I suggested in both high and ligt load. All to low voltage with low load on processor will lead to freezing. It's about making finding the correct voltage for all tasks. I remember testing to find a ok Oc on my 4930Mx. With very low voltage I could run most of benches, but processor crashed with a simple full virus scan with Windows Defender. I had to up voltage for all tasks. Only testing your Oc with max load in bencmarks isn't enough. And 1.339V for 4.2/4.3 GHz is sky high. Run an unlocked i7 although it's BGA under 4.1 GHz all 4 cores is a shame. Better purchase an fully locked 6700Hq!! If people absolutely need lower muli for portability and without being connected to electricity they could use an other profile in Throttlestop for this.

 

I'm going to fine tune mine while at 4.0x...

As I've mentioned when I run at my eco mode, 3.6x I can UV as far as -200mv core / -65mv cache, with zero issues and it runs very very cool.

I'll see how low I can stretch it at 4.0x ...

Being able to run at 4.0x at 1.339V doesn't necessarily mean it's a bad thing. There are a lot of variables, but if I'm able to UV that low on 3.6x, I'm sure I can get some pretty good UV at 4.0x ...

We're talking about 6820HK and 6700HQ here...not 6700K. Different class...so it's irrelevant to this thread.

Have you tried these before?

 

I haven't but I'll check them out. Thanks mate!
