[i7-6820HK] Overclock Settings for 4.0GHz to 4.3GHz (Stable)

Yeap, and the extra low on the cache voltage results in a nice drop in thermals.

And ThrottleStop reads it perfectly. I think im even able to adjust it using TS. Not sure though.

 

Excellent.

I'm on it and will report back.

Thank very much for the info.

Hmm...it just froze...

I tried -50 on Core and -500 on Cache.

Does anything on the screen shot look out of place?

@unclewebb Is there any place we can send bug reports / suggestions for the current ThrottleStop Beta? I too can run some test with adjusting the core and cache voltage offsets independently.

Ok so now im confused? Why are we putting - voltages?
Sorry to be stupid but I really would like to get up to speed with this. Surely if you don't get a bsod using say anything over 1200 in the bios voltage setting then if you minus voltage in XTU, you would then get a bsod right? Because your taking it back down?

Confused...... Sorry

 

Now I am confused. My Asus Skylake desktop motherboard bios has a single adjustment for Core / Cache voltage. Same thing when using Intel XTU. Based on this, I just assumed that it was some sort of limitation with Skylake. I have been adding code to ThrottleStop to try and force this upon Skylake users but it looks like that is a mistake. I should leave things alone so users can adjust these however they like.

@iunlock - In the top right corner of your screenshot, ThrottleStop is reporting the -500 mV Cache offset that you just set. A lock up seems to confirm that these 2 voltages can be adjusted independently. I will have to play around with this some more to see what I can figure out.

@Tony V - Feedback is minimal so just send me a NBR message if you find out anything interesting. I like some fan mail once in a while.

 

@unclewebb It looks like Skylake eats everything of possible voltage adjustments. Also @Mr. Fox @bloodhawk See it this way. Think it's a wrong move if you change the voltage adjusment totally so that only 1 voltage control fixes both core and cashe.

 

Thanks @unclewebb. I agree that it'll be a good idea to keep the adjustments independent as you've stated =)

Appreciate all that you do.

Cheers.

I should stop using XTU trying to figure out what Intel is up to lately. That program and the bios on my Asus Z170 board had me believing that the core and cache voltages could no longer be changed independently in Skylake. Maybe some of the locked, non-K Skylake CPUs have this limitation. Not sure. Easiest thing to do is to leave that part of ThrottleStop as is so users can adjust their core and cache voltages however they like.

Thanks for the feedback.

 

Thank you as well. Great work.

Hello iunlock. Could you spare 5 minutes and explain about Voltage offset using XTU or Throttlestop?
Why you do it? What benifits? Is it better to do this?

Much appreciated

 

Absolutely.

I use Throttlestop to adjust my voltage. Basically, not all silicon are created equal so your CPU may be burning more gas than it needs to. When we under volt, we are essentially trying to improve the fuel economy.

The benefit of under volting are as follows:

1. Less voltage = Less heat so your engine will run cooler. (Heat = Electronics biggest enemy.)

2. Under volting does not take a performance hit as long as you tune it right to the point where it will not BSOD on you.

3. You will burn less fuel (better MPG) when on battery mode.

It will take a bit of trial and error to find the sweet spot, but once you do, pay attention to your CPU Core Temps as it should be running a few degrees cooler.

Under volting is completely optional and not necessary. Ex. When I run at 4.0x on all my cores, I don't really care about under volting, but if I were to be running on battery, I run it at my Eco Mode, which is at 3.6x with an under volt of -200mv on the Core and -65mv on the CPU cache. That is quite a bit of under volt for the 6820HK, and keep in mind that mileage may differ. Take for example @VICKYGAMEBOY with his 6700HQ, he is able to run it at -175mv/-175mv! That's insane! Pretty impressive...

Hope this helps...let us know if you do under volt as it'll be interesting to see your results of how efficient you can get your silicon.

Also, please post your results on this thread:

Hi,

I have an Alienware 15 r2 running the 6820hk and the nvidia 980m gpu.
yesterday I tried to overclock my cpu to 4.1 ghz using these settings via bios. Everything went fine. Ran some benchmarks in XTU and saw the max cpu temp was 83 degrees. I was a bit worried so I booted back in to bios and disabled the overclock and disabled performance mode. Now today, running basic clocks. My cpu is still becoming 77-83 degrees while gaming. This even slows down the game eventually..
What happened?
I need help..
Excuse me for my bad english!

Update: Some cores even hitting 90 degrees now.. this is bad

 

Reaching those temps is very common. = No good.

It is highly recommended that you repaste your CPU and GPU.

could you tell me what im doing wrong ?

http://www.3dmark.com/compare/fs/8755795/fs/9744932#

 

Some thermal pastes aren't able to operate at certain temperatures properly.

Maybe it went past a certain temperature and sort of just dried out or gone bad?

You can use GC-Extreme with LN2, but you wouldn't want to do that with liquid metal.

Using less voltage is the same as using less gas per RPM, but if you increased the frequency while maintaining the same voltage, it will use more gas since you're now running at higher RPM but the gas per RPM ratio is still the same.

So you still end up using more watts just for overclocking at equal voltage vs your stock frequency.

 

Probably a combination of a nice throttle mess, not same Oc, locked vbios, use of another driver + latest version 3DM suite has bugs(Physics test). Rather try a apple to apple comparison

 

Precisely and yes increasing frequency would use up more gas, however, what I was referring to is that an "x" amount of volts at 4.0GHz, undervolted to a lower voltage would be more efficient. ie...better MPG. Yes, it's all relative with many different variables at hand.

 

Hey guys I got my GT73VR last saturday.
I OC'ed it to 4GhZ and 3.8Ghz with a 40-50mv negative offset in XTU
But my main concern now is that I dont like using software to OC.
I want to set the settings in bios to have them perma 24/7
My temps dont go above 66-67c when gaming on a cpu intensive game.
When I set the multiplier to anything it resets after the first reboot even tho the laptop is stable an di restart the correct way.
If I set in XTU and restart correctly the OC sticks but I want to do it on a hwardware level.
Also I cant set the voltage offset to a negative value in BIOS and I dont see even alot of options in the bios to change
Is the BIOS on GT73VR limited in anyway

 

Are you able to adjust the multipliers in the BIOS at all? If so, do that and then use Throttle Stop to adjust your core and cache voltages. Try under-volting them in increments of 5mv to start off and keep going down from there.

I would also check to see if there are any posts available of other GT73VR owners to see how far they have been able to under-volt. From there, you may be able to use that as a base to work from, which is what I normally do.

 

XTU is perfect I reached a score of 1380 so far without passing 1.2v or 80c which are my limits
I had a question tho what is the maximum safe tdp for 6820HK for 24/7 use ?

 

XTU does affect bios, you don't have to change it every boot because the settings just "stick" (unless you reset computer).

For safe limit, you can test with OCCT for 6+ hours. Make sure temps are lower than 88c (use fan turbo button). Repaste if your temps are too high, because MSI uses toothpaste on their laptops...

I dont understand how in the hell at stock clocks........im getting temps like this while you guys are getting 80's at 4.2 and 4.3ghz....wtf....


and i repasted with Arctic Silver!

 

An you mean AS paste is good? Not for laptop hardware. Use a better than paste this outdated As. The application should also be properly executed if you want ok results.

 

Yikes. As much as AS being a bottom of the list paste, high temps in laptops can be highly be due to improper contact of the die and heat sink and / or not enough paste.

Even with AS you shouldn't be reaching such high temps. In all seriousness, even toothpaste will yield better results.

I'd first order either:

* Gelid Exteme
OR
* Grizzly Kyronaut


...and repaste again, only this time being a little more generous with the paste to ensure complete coverage. It'll also make up for any unevenness between the contact points if it exists.

Hi iunlock. If you have time, is there any chance of getting a clear explanation or some sort of tutorial for adjusting the voltage using Throttlestop and what features we need to know about and what they do? I'm scared i'm going to change something and screw things up.

Thanks

 

Why won't Throttlestop minimize to tray? Only to task bar. Any ideas?

 

I'll get a screenshot and post it up as soon as I can.

::iunlock::

 

Thanks alot! Any ideas as to why Throttlestop won't minimize to tray? Only task bar?
Thanks

 

Are most of you able to keep temps below 80 C if you run the chip @ 3.5 GHz?

 

My temps stay under 80c @ 4GHz, if you are hitting those temps at 3.5GHz then I reckon you need to re-paste, and quickly!

 

Just started to work on the new AW17R4 CPU OC....

So far...

 

AW 17 R4:

I just put in your 4.3Ghz settings at 1150 and got a BSOD instantly on boot haha.

4.1Ghz is super stable tho right now, just BIOS settings, not sure what to do in XTU yet

This is my IC Diamond Repaste I did today - first laptop repaste ive ever done LOL

 

Great to have you sharing your results! We need more of this.

As for the settings, those are rough estimated base figures...not all silicon is created equal so it varies a lot...trial and error is the nature of this game, but very rewarding in the end...

 

Ran a stable benchmark at 4.2Ghz - got the exact same score, gonna have to play around with it.

 

Sounds good. Keep us posted! Good luck!

 

sorry to tell you but you have ruined the surface of your beautiful and expensive silicon chip with that trash thermal paste!

 

ok.... lol. Wasn't planning on doing many photoshoots with it anyways

 

Need not to worry as it doesn't hinder the performance, but while some don't care, a lot of others do.



You should opt for liquid metal next time. We'll be rooting for ya...

Below are the conductivity numbers for the top Liquid Metals and Traditional Paste:
(As we know the numbers don't mean everything, however, from all my tests done so far, Grizzly Conductonaut has always topped CLLU by an average of ~3C. Results may vary. However, because I am repasting, every drop in C's count. It could make all the difference in some scenarios. To each his own...)

Liquid Metals:
Thermal Grizzly Conductonaut - 73 W/mk
Coollaboratory Liquid Ultra - 38.4 W/mk
Coollaboratory Liquid Pro - 32.6 W/mk

Traditional Paste:
Gelid GC Extreme: 8.5 W/mk
Grizzly Kyronaut: 12.5 W/mk
ICD: 4.5 W/mk

 

Pretty Amazing! I'm just amazed by how bad my stock paste was.... the temp difference of IC Diamond is alot. So im guessing this benchmark would show about 84 degrees instead of 87 with Liquid metal yeah?

I'm just a little nervous by the conductivity of liquid metal as far as messing up my chips or motherboard. Are mistakes reversable LOL!!

BTW, I turned down my GPU Clock and Memory, and my CPU benchmark score went UP almost 80 points from 1190 to 1270 - Same temp / speed.

That would indicate some kind of voltage draw that the Nvidia GTX 1070 GPU is having that would lower the CPU power correct?

 

I actually bought IC Diamond off your Liquid Metal Showdown recommendation where you mentioned if someone has never done a repaste before. My local Microcenter had it and it was between that or MX-4 haha!

 

Why should lower graphics settings Increase XTU score? You have not maxed your psu. XTU is a processor benchmark for Gods name!! Have Dellienware engineers crippled something again? EG Limited max power draw with firmware? Run bench several times. Wprime 1024M stress test and Cinebench R15 as well.

 

My 6820hk would overclock to 4ghz but wouldn't hold it's clocks and now for some reason I cannot get it to overclock past 3.6. I have tried all different settings in the bios and I've tried resetting the bios to default and still no joy

Any Ideas guys?? I had this issue on my old 15R2 and resetting the bios solved it but it's not working on the 15R3

 

Try resetting NVRAM.

 

Are you also adjusting the voltage? The stock voltage can only get you so far. Usually the 6820HK can handle 40x stock pretty easily. Some can even handle 41x without messing with the voltage. But, anything beyond that will need some adjustments.

How high is load voltage for most of 6820Hk @ Stock Clock?
