P775DM3-G Overheat Advice

Hey everyone,

I recently bought a P775DM3-G laptop (with a GTX 1080 and i7 6700K) from Scan.co.uk and so far my experience has been very negative..

Supposedly Scan.co.uk does performance checks on every laptop it sends out, but out of the box my laptop was completely under-performing, with CPU apparently throttled permanently at 20% performance (for whatever reason). Their customer service was no help whatsoever but eventually I managed to fix the problem by resetting the BIOS to default settings.

After getting rid of the throttling issue, like many other users on these forums I ran into the severe overheating issues: pretty much any game I run on this laptop (be it very intensive games like the Witcher 3 or relatively low spec games like Overwatch) the CPU and GPU temps run above 90°C within a couple of minutes, and keep climbing until I decide I don't want to fry my laptop and switch off the game.

The main advise on the forums appears to be to undervolt the CPU between -100mV and -150mV. Other users also suggest to set the GPU to .925. The problem is I have no experience whatsoever with overclocking or tweaking CPU / GPU settings so I'm a bit hesitant to change anything that might cause problems to my laptop.

As such I want to ask advice on which software to use to set the voltage? I have Clevo Control Center .98 installed, should I try and do it in there? Is there anything I should change in my BIOS? Should I install a different software for fan control / throttling?

I'm aware that for most of you these are probably complete noob questions but any help is very much appreciated !

Edit: hope it's OK if I tag the people who seem to have most experience with this issue: @Phoenix @Mr. Fox @Shakeeb Anjum

 

Download AIDA EXTREME (we can do it with this app alone).

In Control Center you have a option to do OC, open that and set CPU Voltage Offset to -120mv (starting point).

Now open AIDA Extreme and do a System Stability Test:
-Select all tests excluding the stress HDDs

Let it run until it shows that the CPU is throttling.

If it throttles add -10mv (try -130mv) if after 30m your CPU did not throttle then -130mv is ok for you.

If you need to keep undevolting, keep doing it -10mv at a time and keep testing until the CPU does not throttle anymore.

If the system starts crashing then you have set too much undevolt.

You system should be able to reach a value where it does not throttle and does not crash even with Automatic Fan Profile.
For better cooling but more noise you can go with the OC Fan Profile.

If you can´t get to a value that allows your system to be stable and not throttle then you have a bad paste job. You need to open it up or send it back.

This is the simple way to do it. Modded Control Center + Throttle Stop would also work, but it´s more complicated to set up.

 

Hi John,

Thanks a lot for your quick reply! Just to be sure I don't have any conflicting settings I've reset my BIOS (I'm assuming this is the stock Clevo BIOS) to default settings, and I've reset the Clevo Control Center CPU Overclock to default values. I've also made sure both Windows power options and CCC are set to "(high) performance" mode (in Windows with min and max processor state both at 100%): http://screencast.com/t/0LV5pemwl

Then under CPU Voltage I've checked "adaptive" and then put it at -120mV: http://screencast.com/t/cYdYrkyq8 . Is that right or should I use "override"?

A couple of questions:
- Are the remaining settings such as CPU ratio override all right like this: http://screencast.com/t/cYdYrkyq8 ? I think they were at 42 for core 1 and 40 for cores 2-3 before I reset to defaults (instead of 28 for all cores).
- Should I change anything under the Memory overclocking tab or leave that at Default: http://screencast.com/t/xkHId4Jsvo5 ?
- For now I guess I shouldn't touch anything in GPU overclock menu?

I'll download AIDA EXTREME https://www.aida64.com/products/aida64-extreme now and start testing

 

Ok so having set the undervoltage to -120mV with the settings linked to above the result is that the CPU doesn't overheat, but it seems to have the CPU capped off at a clock of 800 mhz, as seen here in the overclock menu / AIDA report: http://screencast.com/t/bwNBuKmXCzw
EDIT: note that the GPU still went to 91°C

This is the same issue I originally had when the laptop arrived and the CPU was being permanently limited to a certain % of performance. Could it be that I have to set the CPU ratio override higher? Or perhaps I'm using the wrong version of Clevo Control Center?

 

Please post a screenshot of your OC settings.
I´m also assuming your are doing this while connect to the AC.

 

1) you are using the Clevo Control Center for the 6xxRS

Different control center version for a different laptop = different fan table settings

2) The latest Clevo Control Center for your lapotp is: 5.0001.0.90

3) The stock BIOS is flawed, when you apply an undervolt, even if you set it as a negative undervolt which is what you want, it actually shows as a positive offset in the stock BIOS. to confirm, go to your BIOS and then overclocking menu, you will see the offset as being positive not negative

4) the stock BIOSs only allows CPU undervbolt/overvolt but not the Cache Ratio. You need to set the same undervolt for the Cache Ratio. that can only done with the Prema BIOS or Throttle Stop

5) since you didn't buy it from a Prema Partner, your only option is to use Throttle Stop, here are my settings, don't go too high like me to a 46 multiplier but increase the power limits and turbo limits to the max, that's safe as the CPU will only draw what it needs so no harm, you are just upping the limits

Here you go, just change the multipliers to 42 and the cache offset to -150mV for both the Core/Cache

TPL are the power limits, maximize them like me, it won't hurt, the system will only draw the power it needs












You can set different speed for diff. profiles and then switch between them easily using predefined hotkeys, I have 4.6 GHz for performance, 4.4 GHz for gaming, 4.0 GHz for internet browsing and 2.0 GHz for battery saving

I set my hot keys to CTRL + SHIFT + 1, 2, 3, 4 respectively

 

Well that is the most "advanced" way of doing this, and yes, it is my favourite way and recommended way
TS ftw!

The correct control center version should work to undervolt CPU but if you follow Phoenix instructions with TS then do also the following:

Use this App: https://www.obsidian-pc.com/files/OBSIDIAN TOOL/OBSIDIAN_TOOLS-1.01.07.zip
Select your model and use the app to reinstall control center!

This way it will install a modded version without the XTU service (it will no longer have the OC bit).

Turn off your system, press FN+D and while pressing it turn on your system, it will reset your BIOS.

Now that you have your BIOS reset and a XTU free CONTROL CENTER, start following Phoenix instruction! Voilá!

 

These are the OC settings as I'd set them: http://www.screencast.com/t/cYdYrkyq8

@Phoenix Thanks for the extensive feedback!! So I'll try the following:
1. uninstall the current version of CCC I have installed,
2. reset BIOS (again) to "optimised defaults",
3. install the version of CCC you've linked to, and then
4. install ThrottleStop with the settings you recommend.

So if I understand correctly I should set ThrottleStop to all the settings in your screenshots EXCEPT:
- "set multiplier" / "turbo ratio limits" at 42 instead of 46
- "CPU Core voltage" at -150 mV instead of -26.4 mV
- "CPU Cache voltage" at -150 mV instead of -26.4 mV

Is that correct?

EDIT: I guess I should then switch out step 2 and 3 for the steps recommended by John@obisidian-PC

 

perfecto

PS: your settings in that screenshot are all messed up man

low multipliers, low power limits, high power limit time (the lower the better, I set it to 1 not 28

rule of thumb = 28 for mobile CPUS ./ 1 for desktop CPUs.

I have a desktop 6700K so I set it to 1

 

Can I ask why the "advanced" way is better than simply downloading the correct CCC and setting undervolt ? (I'm afraid there's more I can do wrong with the "advanced" way)

 

did you read the post above this that I made???????? (see point #3)

Please re-read it again and see what I sad about how flawed CCC is and what happens when you set a negative offset in CCC vs what you see in the BIOS and no Cache voltage control!!!!

 

Those were the "default" settings when using CCC version .98 (except for the voltage which I changed)

 

well those settings are telling the CPU to run @ 2.8 GHz

 

Ah right apologies, not showing negative offset in BIOS (but using it anyway) didn't seem like that much of an issue, but yes Cache Voltage control sounds important Sorry, brain is fried today.

 

Ok so to summarize I'll:
1. uninstall current version of CCC
2. install the correct one using the approach recommended by John (modified version without XTU)
3. install ThrottleStop and apply settings recommended by Phoenix

=> awesome guys, learning a lot already, just completely new territory for me ! Will post results as soon as I have them.

 

1. uninstall current version of CCC - The app i pointed will trigger uninstall and resume install after reboot

After installing the correct one please reset your BIOS:
Turn OFF
Press FN + D and while pressing it TURN ON the laptop

 

=> does all of this (such as FN + D key) also work on Scan.co.uk laptops? The tool mentions this is an Obsidian tool Don't want to accidentally mess things up

 

Should work on all latest CLEVO based models including Scan.co.uk.
The tools is for drivers, which are the same no matter what reseller you bought.
We did not lock our tool to our units only, we could have, but then Phoenix would beat me with a stick!

 

Haha thank God for Phoenix then. This tool is awesome think I know who to pick next time if I have to choose between Scan and Obsidian.. Tech support at Scan was literally like: "oh ehm your laptop is running at 20% CPU? Hmm that's weird, we normally check that sort of stuff. Well do you want to send it back and get a refund?" I'm like no, just help me fix it, I aint going to send it back to the UK from Belgium and wait another month for a new laptop lol.

 

PS: Uploading lots of drivers for you, please standby, we have a long night

 

So I think I did everything as told, but when running AIDA EXTREME Stability Test the CPU temps are still quite happy to flirt with the 100°C mark. Any idea what I'm doing wrong?

Here's the settings I've used in ThrottleStop - everything except the areas marked in blue should be the same as Phoenix' settings:

 

Please repaste your CPU using the X Cross method with IC Diamond as it makes the best contact with the heatsink due to its thickness:

The X Cross method is the best in my experience as once the heatsink is fitted, it provides the maximum coverage with the least air bubbles





Do that for both the CPU and GPU

 

I've also noticed I can still reach the OC bit of CCC, despite having used the version included in the Obsidian driver tool. The CCC OC tool shows different settings than ThrottleStop; I'm assuming ThrottleStop overrides whatever is stated here: http://screencast.com/t/DEU0idFrM3 ?

 

Thanks for the suggestion but it should have just been pasted with Arctic Silver 5 paste (which gets good reviews) by professionals from Scan.co.uk (who presumably are better at this than I am, since I've never done this before) Seeing as after I started using ThrottleStop my CPU throttles even faster than it did before I have the feeling that I might still just have a wrong setting somewhere (before I start messing with the interiors of the laptop and possibly voiding my return policy)

EDIT: note also that I don't necessarily need this laptop to be 100% perfectly overclocked - I just want it to run fine at stock speeds for extended periods of time without overheating. Intended uses are long processing of 3D data and Virtual Reality.

 

Check if you have a XTU service running in the background! If so kill it before it lays eggs.
Check your startup list and untick any XTU related service running.
Reset your BIOS again.
When you apply using TS you no longer need to look at CC OC stuff.

 

Since i bought my laptop it has always had problems when i overclock it above 4.2 but if i play any games on the stock settings the games run smoothly without any throttling and temperatures stay nominal, i have played a number of games which include

1-) Gears Of War 4
2-) Max Payne 3
3-) The Witcher 3
4-) Metro 2033 & Last Light Redux
5-) Shadow Of Mordor
6-) Crysis, Crysis 2 & 3

In the beginning i had problems with GOW4 but as @Phoenix suggested that i don't need to overclock if the clocks are not stable and let everything be on stock settings and i also followed what @Papusan said that for gaming i don't need to overclock the stock settings of the 6700K will be more than enough along with the GTX 1080 to play games.

By stock settings with a 6700K you mean mulipliers/clocks right? Becase you sill need to undervolt with stock clock or it will throttle on A LOT OF GAMES.
These new games which are ports from consoles are CPU hogs!
You need to undervolt if you want your system to run perfect, specially with a 1080 + 6700k!

 

Do you want me to do it for you by TeamViewer?
I can fix your system really fast unless the paste job is wack!

 

Get rid of this AS5 junk. Maybe ok for hardware in desktops but not in laptops. And You can't be sure that the paste job is done properly. Use the method bro @Phoenix suggested for you. And don't use other thermal paste than ICD, Gelid Extreme or Grizzly Kryonaut. For absolutely best results delide your processor and use Liquid metal.
You will never get your thermal problems solved without this steps!! Undervoltage is only the lazy mans work.

 

Not 100% true
Even with all that the CPU will still throttle im afraid.
Even good thermal paste + delid&liquidmetal + copper to remove gaps cpu will still throttle at 100% CPU + GPU usage!
Ok one can say it is VERY rare to have such usage of 100% both gpu and cpu but still, for me a perfect system is one which you can leave it all night pulling everything at 100%.
At the moment my best is -120mv, with -120mv i can leave my system all night long pulling both cpu and gpu at max and my cpu wont even go above 80ºC!!! Which means there´s plenty of room to OC!!

 

Yeah, A bigger chance for throttling with a pure Unified heatsink design like in this model with max load on cpu/graphics. Shared pipes + the whole heatsink package isn't what I prefer. Work well with high/max load on processor, but fire up graphics load will increase the whole temp. Regardless.. I mean he should apply new and better thermal paste.

 

Sorry for the late reply, been out cold with the flue for two days!

I think this might be the issue; found I have Intel XTU running in background (see image), however it doesn't show up in my software list, nor in the startup processes on Windows, so I'm not entirely sure what is starting it..

If this isn't too much trouble, I would be ridiculously grateful.

 

- exactly Shakeeb! The hardware at its intended clock rate etc should be more than enough for what I need I just don't want my system being damaged by overheating due to the voltage apparently being too high :/

 

Voltage and clock manipulation is cool to play with when it's needed ─ maybe down the line when software demands rise ─ but yes: For a lot of people, keeping things at stock works well.

 

Hi everyone!
I have been looking for answers in many forums and no luck so far.
Try my best shot here since it seems you guys know more about this laptop.

Before I start let me tell you I have tried everything, reseting CMOS, reinstalling the drivers, even used OBSIDIAN installer to install everything.
So far I have been very patient.

My temps now rise up to 100C.
My laptop was also bought from scan.co.uk (3XS) as the OP's.

My issue is the following:
Whenever I play and start a demanding game, I turn FN+1 on to have 100% fan speed.
Now the issue is inconsistent, sometimes I play for an hour, sometimes just 30min or 15min until the issue kicks in.
The problem is my fan's automatically go on lower speed than 100%. I suspect it is 80% based on the sound of the fans.
But the issue is this is simply not enough to cool the 6700k and the 1080 together.
My temps are in the high 90C's.

I have tried undervolting, my clock speeds are at 4GHz. No overclock on GPU.
After I notice my fan speed's drop, I immediately turn off the game.
After a while the system automatically goes back to the original 100% fan speed and now I can use FN+1 again.

When I am in the system doing just light work on the laptop, I can run FN+1 all day long (haven't tested that long but it seems so).
Even tried to run Unigine Valley and the FN+1 did the trick, no fan slowdown's.

Now every game is affected by the issue so it is not game ENGINE related or game type.

Could anybody shed some light on what is going on or if it is fixable?

 

Because CCC is a clunky poorly coded piece of **** software.

 

It depends on the type of user you are really, if you just want to set and forget then it just sits in the background and does not get in the way.

 

It actually does. Messes with services it is not supposed to.

For example with CCC installed : If i want to update my license server for fumefx, for the life of me wont it let me do it (i need to stop my AFLICS serive, that manages licensing for this particular plugin). The moment i get rid of CCC, i can do everything normally. And its not just this service, its messes with a lot of other ones.

 

it messes with any overclocking i do within nvidia inspector and hence why i don't have it installed.

 

Even if you turn the overclocking off in CCC itself?

 

@Phoenix @ZephyrZ
Sorry to bring out a relatively old thread, but I am considering buying a Clevo P775 in the short future and I've read a lot about that throttling issue.
Now my question is if you can set the turbo to standard as I like to use my notebook on my lap and don't want it to run at 4.2Ghz if I quickly disconnect the cable.

From what I understood, the solution with TPU will keep my system permanently at 4.2 (or 4.6) GHz if it's set up like described in the screenshots. Am I right that if I don't set the multiplier, the core clock will be managed by the system itself?
If this is the case, I could also set up a second configuration (like mentioned changeable with ctrl+shift+1/2...) with an overclocked speed (4.6Ghz for gaming for example), right?

Also, another question is if you don't have to set the GPU voltage lower. I read that a lot of times as well but here it wasn't a topic. Doesn't throttling happen when the CPU voltage is set lower?

Thank you in advance.

 

@Phoenix

You really do walk the extra mile to help people, don't you?

 

always my friend

 

It's been about two weeks since @ John@OBSIDIAN-PC tweaked my ThrottleStop settings, I've had some time to test the laptop "in real world environment" so a little update from my part!

After playing with the ThrottleStop settings, running AIDA64 Extreme "System Stability Test" in order to stress the system and monitor for throttling, and since John knew I don't necessarily want an overclocked system, these are the final settings he set:


My system kept overheating even after quite extreme undervolting (most we tried was -172 mV) during the stress tests, and at those undervolt levels the system was prone to crash, so we eventually stepped it up to -160.2 mV and kept the "turbo ratio limits" for each core at 40, which I guess is the stock speed, which is fine for me. Although it would still keep throttling eventually during the AIDA stress test at these settings (after about 5 mins), as John pointed out normal computer use never stresses the CPU and GPU for 100% for extended periods of time so it would be unlikely to actually be an issue during normal computing, which brings us to the real world scenarios:

When GAMING:

Over the past two weeks I've generally:
1. started up ThrottleStop each time I launch my computer
2. as a standard kept my CCC settings at Entertainment => System Program => Fan speed: automatic, Power conservation: balance

With these settings all my games run smoothly, and temperatures are generally around 70° while gaming, sometimes going into the 80° region, but never in the 90°'s or even 100°+ like they were before. Fan noise is of course audible but not an issue with simple earbuds.

However, I did notice that if I run intensive processing software, in my case photogrammetry software (generating 3D models from images), using the settings above the temperatures will slowly start creeping back into the low 90°s (after about 20 minutes) since the CPU or GPU are running at full capacity for a long time. I stopped the software when the CPU temperatures reached 95° but I had the impression that if I hadn't stopped it it would just have gradually kept going up, so...

W hen RUNNING LONG INTENSIVE COMPUTATIONS:

I now do the following:
1. connect my laptop to one of those USB-powered external fan systems which you can place under your laptop
2. start up ThrottleStop when I launch computer
3. set CCC settings to: Entertainment => System Program => Fan speed: overclock, Power conservation: still balance

By using the additional external fan, and setting the fan profile to overclock the temperatures during intensive processing quickly drop to around 70° and stay there, which is even better than I expected! Using the overclock fan profile the fan noise is of course quite annoying, but this is really something I will only need to use when doing photogrammetry work abroad, in which case I can leave the laptop processing in another room and not worry about the noise.

So in short using the ThrottleStop settings set by John@OBSIDIAN-PC, and by switching between automatic fan profile and overclock fan profile I can now use my computer for any period of time, for anything I want to use it for (essentially Virtual Reality, photogrammetry processing and general gaming) without it overheating, and without the CPU being permanently throttled at 25% capacity like it was out of the box!

An enormous thanks to @John@OBSIDIAN-PC, @Phoenix and everyone else on this thread for the suggestions and being helpful in fixing this annoying issue, despite my utter lack of knowledge in this area !!

 

Nice of you to report back, as i told before, there´s a limit to what undervolting can do, the best thing would be to do a proper paste job.
Still that seems like a decent usage from you, way better then getting a caped system that throttles like crazy.

 

Hi everyone!

I have been looking for answers in many forums and no luck so far. Try my questions here since it seems you guys know quite a lot about this laptop.

I recently got Clevo P775DM3-G / 3XS / Octane / Sager / Eurocom or call it however you want. And I've got few issues with it.

My laptop was also bought from scan.co.uk (3XS)

My (3XS) system is running at stock settings on:
Windows 10
17" 4k Display
i7 7700k Kaby Lake
Geforce GTX 1080 8GB
8GB RAM 2133Mhz
2x SSD (Raid)

When running on Idle i have ~34°C (CPU) which i am comfortable with it and around 38-40°C on GPU.

Even though didnt get any issues while playing Black Desert on 4k Resolution on Ultra. Now installing Witcher 3 to test to see if I get any issues as people say it's a demanding game.

Running Aida Extreme for Stress Test (CPU/FPU/Cache/Memory) i get 95°C in few seconds and then i stop it straight away because it goes to 100°C+ and starts to throttle.

Running FurMark on 1270x720 stress test it goes to 95°C in about 10 seconds and increasing by the time, so i stop it at this point. (as I noticed on this forum its not the best way to stress GPU, so ill try a different software)

I don't know what would be the reason whether it is Voltage / Thermal Paste / Bios version / or Heatsink. It just runs at stock settings.

Haven't tried to lower the voltage (like John@obsidian and Phoenix recommended) yet as I'm not sure whether I need to do same procedures on i7 7700k.

Seems @Phoenix , @bloodhawk and @john@Obsidian are very helpful. You really do walk the extra mile to help people. Very nice of you.

Please advice. I can upload any screens if it'll help.

Also my friend wants to get one as well as he is not sure yet whether it is worth to buy a Chicken Grill or not.

 

Start with undervoltage if you run stock speed. Will help on max temp. Idle temp isn't that important. Delidde your processor and applying liquid metal under IHS, this will lower the max temp with up to 20C degrees. + Use a proper thermal paste between IHS and HS. You can as well have a ****y Quality heatsink. Pretty normal from Clevo. But start with what I suggested first before you take a conclusion on the heatsink quality. ICD thermal paste is preferred if the heatsink don't sit perfectly flat on hardware and are of goofy quality.

 

I have the exact same system, so you may check my process achieving good temperatures in Witcher 3 while not loosing performance.
http://forum.notebookreview.com/threads/gpu-undervolting-at-p775dm3-g.801064/page-2#post-10452266

Undervolt your CPU by 100-150mV (Throttle Stop may be the best option, but Intel Extreme Utility does it's job as well) and if you have problems with graphic card temperatures, you can find a way to solve those there.

The only difference will be that my CPU was delidded by my vendor, so my CPU temperatures will be lower than yours by default, although I don't use the CCC (with the overclock fan setting), as I feel like it overrides every Windows setting wasting my battery runtime.

 

Hi Eqinox,

I have the same P775DM3-G laptop from Scan. I'm on my second now, as the first died due to motherboard failure after a week of ownership.

Both laptops as received had temps in the mid 90's for CPU and GPU under heavy load, and both had awful paste jobs with way too much Arctic Silver 5 which isn't a great paste. The second (read current) laptop's heat sink wasn't mounted correctly and one of the retaining screws was half in and cross threaded.

For a 4.5KG laptop of this size the cooling system is subpar and needs all the help it can get. I would follow the advice of the other members on here, and get it re-pasted properly with a decent paste. Since you have the 7700K, I would also recommend you get that delidded as well. Once the hardware is sorted out, you can work on under volting the CPU to get temps down even further.

 

Wouldn't the repaste break my warranty?
