[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.

I still find it weird that even if i under volted and limited my gpu voltage t0 850mv i still generate the same amount of heat. I still get a constant 85-86c, at least it doesnt surpass that, but it will shorten my notebook's spanlife for sure


+1
Any manipulations with Afterburner doesn't lead me to avoid heat issue. Even 80 degrees seems impossible for me.
Luckily, i don't play much, so my system doesn't have serious heat "damage" for quite a while.

Ive read removing this notebook's dust tape from the vents help the cooling you guys think it will help?

Read Onjax first post

Hello,

I just exchanged my recently bought GL502VM for a GL702VM.

I wanted to ask if anyone has used/is using a vakum Laptop cooling fan (something like that https://www.amazon.com/dp/B01LEWRAC8?psc=1) with the GL702VM and if it helps reducing the Temp & fan noise ?
I figured that the GL502 has a really stupid Screen covering the exhaustions, so can't use those but the GL702 should have enough space.

Also, @Matt I wanted to use your Afterburn Profile which Keep the Freq @ 1500 but when I apply it Afterburn Increase it to 1600 every Point in the graph get increased by 100 ?

Yes, i have it, you can see it a posts before.

I think the issue is that it's very dependant of the specific chip you have in your system. Some can cope well with significant undervolting, while some become unstable with even minor undervolts. Anything Asus did would have to take this into account which would:
1. Require customers to understand what they were doing, & most wouldn't
2. Encourage people to purchase/return laptops until they got one with good undervolting on both CPU & GPU

Onjax's approach reduces temps without any significant loss of performance if your chips can undervolt

My profile limits clocks as well as voltage to remove potential stability issues if your chips can't

But do the Onjax approach cause loose of performance? I dont notice it on GTAV.

By closing MSI Afterburner do the volts come to default values? Or is it needed to press somewhere else? Not sure about this...

I am using -0.125mV CPU with Onjax profile 5 and seems ok so far...around 85C both. Sometimes can peak to 88/89C on some parts of GTA V.

Thanks.

Undervolting doesn't have a negative impact on performance, as VCore is not related the actual processing speed of the chip. It can however cause instabilites or if you set up the Afterburner curve the wrong way make the GPU prefer a lower clockspeed. But texture popups, as one user here describes them, are not linked to undervolting. Textures are loaded in and from the GPUs RAM, which was not undervolted or underclocked in any way. So maybe it comes down to subjective impression.

Kompensan - no, your voltage/clock profile won't revert back to the default until you click the reset icon (you might need to click apply afterwards as well... not sure).

Anyone else - is it possible to edit the curve below 800mV? I'm interested in seeing whether I can create some super-low power profiles for when I don't want to bother anyone with fan noise.

Thanks in advance.

Yes I dont know but after press Reset I cannot access to the Apply button so I just saved default settings on Profile 1 to switch it easily.
I did this because some games run fine with the default factory profile.
