[GL702VM & similar] Solution to Performance issues / Overheating / Throttling / Whine

onjax
Level 9
Hi guys, I bought GL702VM and was upset with its ability to handle games and high load. I had immediate temperature jump to over 85 jump and throttling / frame drops in games. So I decided to understand how to improve things, even though, I already lost my warranty due to my experiments, but at least I can answer for everyone, that:
- the main problem of this notebook is inefficient, insufficient cooling system with too thin fans, too small heatsinks, vent holes in a wrong places (aside, not above the fans).

To prove this, I first changed the thermal interface to liquid metal. That doesn't solve the issue. This proves, the thermal contact is ok, but heat dissipation is bad. Second, I ran stress tests with back cover removed - helped a lot, about 15-20 degrees off. The proves that air intake is wrong in this system.

I also removed an antidust tape with holes covering all the intake holes. That helped by around 5 degrees and also brought down air noise.

Then I came to idea of downvolting CPU and GPU, thanks to devs of ThrottleStop and MSI Afterburner, we can do this with relative ease.

The result: Fan noise reduced by half. Temp drop is huge. More speed due to ability of CPU/GPU to properly boost to max speed.

For your information - CPU is responsible for about 30% of heat, GPU - for 70%. So best idea is to undervolt the GPU, but for best results go for both.

THE GUIDE - CPU
Variant A - Install Intel Xtreme Tuning Utility

  • Go to Advanced Tuning tab and Change Dynamic CPU Voltage Offset to negative value (move slider to the left). -100mV is a good starting point. Leave Mode to Adaptive.
  • Apply changes.

My CPU holds -150mV well.

Variant B - Install Throttle Stop 8.3 or above

  • On main window click FIVR button
  • Under CPU Core Voltage move Offset Voltage slider to the left. -100mV is a good starting point. The lower value the less heat.
  • Click Apply. On the same window you can save settings to make them apply every time you start the app.


THE GUIDE - GPU

  • Download and Install MSI Afterburner 4.3 or above
  • In settings turn on Unlock voltage control and Unlock voltage monitoring
  • Close MSI Afterburner
  • Download my Voltage Profile for GTX 1060
  • Extract profile to some folder and then copy file to "C:\Program Files (x86)\MSI Afterburner\Profiles". Click continue as Administrator when Windows asks permission to write.
  • Run MSI Afterburner, click on profile 1 (out of 5). Then press Ctrl+F. (1 - least heat, but may be unstable for some... 2, bit more voltage etc till 5.)
  • You will see my Voltage Curve (screenshot). What you'll see that it's flat until 1050mv. that means. 1050 will never be used, so will never be used any voltage except 831mV @ 1860 MHz and below.
  • Click apply to test this curve
  • If this curve is not stable for you - edit it to your taste: Click on 831mV dot and move it lower, so that lower freq will be used for that voltage, and for 1860 freq next available voltage will be used. Etc. Work with leftmost voltage dots to make everything stable.


This curve drops heat of GPU by at least 30%, which is huge.

THE GUIDE - COIL WHINE
Workaround described here: https://support.microsoft.com/en-us/kb/975530

Perform only these steps as Administrator:
1. At a command prompt, run the following command:
reg add HKLM\System\CurrentControlSet\Control\Processor /v Capabilities /t REG_DWORD /d 0x0007e066
2. Restart the computer.
3. Run ThrottleStop v8.3 or above and uncheck C1E. Click save.

In theory, it will make CPU a bit hotter while system is idle, because it disables some advanced C-states, but i didn't notice that in monitoring app.
That solved like 99.9% of the noise, and in addition, disabling C1E in ThrottleStop solved noise issue completely.

After using this method I had some instability issues (windows randomly crashing on a blue screen)
So I put these settings back off again, but I think my laptop makes a wierd inconsistent buzzzz sound when idle 😕

You have to change the curve one or two voltage steps higher. Open curve by Ctrl+F and drag the leftmost dots (up to 850-875mV) below the main flat line of 1860MHz to i.e. 1800 MHz. This will raise up voltage a bit from 835mV to 850mV for 1860MHz. Click APPLY. Check stability and continue.

I might update my profile for you with several presets to try.

Awesome guide - thanks for taking the time to write/share it.

Out of interest, if you've checked the "apply at windows startup" icon in the tool, do you need to load up the MSI Afterburner tool, or will it apply the changes silently in the background?


Yes, it will apply settings silently. Hold CTRL while logging in to Windows to skip applying Afterburner settings.

Thanks for replying :D, what voltage curve do you recommend me? I'm getting 85 degrees while playing GTA V and Doom 😕 .

As every chip is different in quality, you might get better or worse results. My profile is just a starting point, which is stable for me.

I might update and reupload my profile with several presets for you to try, from most powersaving to more stable. You can select profile in MSI afterburner by clicking 1,2,3,4,5 buttons and click Apply.

Hey onjax, your website is down. I managed to create a profile for my 1060 but I need to see you curve. Can you rehost it? Thanks.

Have you tried repasting the heat sinks?
Stock thermal compounds are always inferior to aftermarket ones.
What are you running as well? The GL702VM is supposed to have three fan for better cooling. *

Read my first post pls, I mentioned Liquid Metal was my first idea, didn't help. Asus uses good paste.

My bad. Somehow I missed it.*
It's good to know Asus uses good paste and installs it properly that even LM doesn't improve on it.*
I can't say the Dell Inspiron 7566 I had is the same. It reached 99-100C with i5 6300HQ and 960M.

I will do some tests once my GL502VS arrives. *

My previous notebook was Acer 7750G with top GPU at the time, switching to liquid metal gave around 15 degree gain, so it's manufacturer-dependand thing of course. Asus makes here a right choice, as I see.
