I have a 2020 Asus ROG Zephyrus M15 GU502LW. This laptop has the i7 10750H processor. It has been slowing down with the processor speed going into low speeds even on high load. It happens inconsistently. It could happen for a bit then it goes back to normal. Clock speeds go back up, then it either stays that way or it goes back down to 0.78 or around 1ghz.
As of now, it is normal. Under limit reasons, it is only tvb shows up in yellow then flashes to red then it goes back to yellow.
When it does happen, VR Current comes up and it either flashes from yellow to red then back to yellow or it is constantly red. Same with EDP Other.

I have my tpl window and limit reasons here which have my current settings.

It happens inconsistently.
Check the ThrottleStop Log File box on the main screen so next time you have a problem, you will have a record of what happened.

The 10750H has a 45W TDP rating. When you set the long term power limit to 90W and the short limit to 135W, that is great but perhaps the voltage regulators were never designed or intended to be used for that kind of performance. You might have to lower the turbo power limits to what your voltage regulators can handle.

Try clearing the BD PROCHOT box on the main screen.

TVB throttling happens if the Thermal Velocity Boost box is checked in the FIVR window. If the FIVR window is not locked, try clearing this box. If the FIVR window is locked then there is nothing you can do about some TVB throttling.

What about the FIVR window?

I will look at that. For the FIVR Window, it's locked.

Also for the tpl values, what recommended range should I test out?

Run a log file first with your present settings. The log file might show that at 60W or 70W, the voltage regulators start to complain.

Exit ThrottleStop when you are finished testing so it can finalize the log file.

Clean the laptop out and reply the thermal paste, it most likely dried out.

I have done that like twice in the past year

What thermal paste are you using and how are you applying it? Some popular thermal pastes only last a week or two in a laptop before they start to pump out.

Your screenshot shows that your CPU is reaching 100°C at 100W. Setting the PL2 power limit to 135W is kind of excessive if the cooling cannot deal with 100W.

I'm using the Innovation Diamond Cooling 7. This laptop is designed to run hot anyways. I get it's excessive. I was just testing values to see if I can avoid the power limit throttling. But it's a hit or miss. Even if the "POWER" sign does not show in throttlestop, sometimes the CPU still slows down. My temps also don't go above 85 even. This is when it's idle. no games running or intensive programs (50-60) or when I'm browsing then it jumps from 60-80 and back. But when it slows down, I do realize that the package power would pass 45, it would be around 45+. And when it reduces, then the clock speed goes back up. I don'
t know if this is normal.

I went with the ICD7 because I hear it's good longevity-wise.

The 10750h will not max out at 100w, the 10750h maxs out at 4.3ghz all-core, that would be around 75-78w.

ThrottleStop shows that it hit 100W. I trust what ThrottleStop is showing.

The CPU calculates approximate power consumption based on the VID voltage. Intel releases CPUs with a wide range of VID voltage values. They are not all created equal and they do not all consume the same amount of power or report the same amount of power consumption.

Even if the "POWER" sign does not show in ThrottleStop, sometimes the CPU still slows down.
A current limit throttling problem is not the same as a power limit throttling problem. Current throttling will not trigger Power to show up on the main screen of ThrottleStop. It is best to watch Limit Reasons for VR throttling. Running a log file is an even better idea.

When I had a laptop with the 10750h, I never saw wattage numbers higher than 82w or so. I used XTU and hwmonitor, I dont remember 100w wattage numbers.

This is the log file. It goes from when it was doing that, and when I changed the tpl values to 90 and 135. It took a while before it came back and it's been alright since. I also played a bit of fortnite as well to test for the log file.

At the start of the log file there is some TVB throttling. That reduces the CPU multiplier from 43 to 42 which is not too bad.

Next up is a couple of seconds of thermal throttling (TEMP). Power consumption is still over 90W and the CPU continues to run at almost full speed. Some thermal throttling is not the end of the world.

This changes to VRTDC messages showing up in the log file. The CPU drops the multiplier down to 8 so the CPU is running at approximately 800 MHz. This is horrible. This is the kind of throttling that you are definitely going to notice while playing a game. The CPU is running at less than 20% of the speed it was running at just a few seconds ago and it stays throttled like this for an extended period of time.

I looked up VRTDC and it stands for Voltage Regulator Thermal Design Current. It is triggered when the voltage regulators reach their maximum current limit. There is a separate VR THERM throttling signal which goes active when the voltage regulators have reached their maximum temperature limit.

The log file is shows that the voltage regulators are not capable of supplying enough current to the CPU when you are trying to run your 45W TDP CPU at over 90W. It is possible that your voltage regulators are defective. It is more likely that Asus simply decided to use voltage regulators without ever thinking that some users might want to push their 10750H CPUs over 90W for extended periods of time. The voltage regulators might be OK to deliver 90W for a short period of time but after they heat up, their performance might decrease. Severe throttling is the result.

The voltage regulators seem OK at the 45W rated TDP but start to trigger VR TDC throttling at about 60W. VR TDC throttling is severe so it needs to be avoided. I have no idea how hot the voltage regulators are getting. If there are no heatsinks and poor air flow, voltage regulators can get quite hot. Improving voltage regulator cooling might help but it might not make any difference. If the voltage regulators are not rated to deliver enough current then they are still going to be inadequate for running the CPU at 90W. Consider reducing the turbo power limits however much is necessary to avoid all VR TDC throttling.

I don't remember 100w wattage numbers
All 10750H processors are not exactly the same. When Intel is cutting CPUs out of a wafer, some will need lots of voltage to run stable and some will be able to run 100% stable with very little voltage. The VID voltage table that Intel programs into each individual CPU is not exactly the same for all 10750H processors. The VID numbers are used by the CPU to estimate power consumption so it can manage the turbo boost function. The required voltage and reported power consumption can vary significantly from one 10750H to the next. The formula Intel uses is proprietary. No one knows how accurately the Intel reported power consumption data represents actual power consumption.

If low reported power consumption is a good thing then I guess you got lucky with the 10750H in your laptop and Vows1x was not so lucky.

At the start of the log file there is some TVB throttling. That reduces the CPU multiplier from 43 to 42 which is not too bad.

Next up is a couple of seconds of thermal throttling (TEMP). Power consumption is still over 90W and the CPU continues to run at almost full speed. Some thermal throttling is not the end of the world.

This changes to VRTDC messages showing up in the log file. The CPU drops the multiplier down to 8 so the CPU is running at approximately 800 MHz. This is horrible. This is the kind of throttling that you are definitely going to notice while playing a game. The CPU is running at less than 20% of the speed it was running at just a few seconds ago and it stays throttled like this for an extended period of time.

I looked up VRTDC and it stands for Voltage Regulator Thermal Design Current. It is triggered when the voltage regulators reach their maximum current limit. There is a separate VR THERM throttling signal which goes active when the voltage regulators have reached their maximum temperature limit.

The log file is shows that the voltage regulators are not capable of supplying enough current to the CPU when you are trying to run your 45W TDP CPU at over 90W. It is possible that your voltage regulators are defective. It is more likely that Asus simply decided to use voltage regulators without ever thinking that some users might want to push their 10750H CPUs over 90W for extended periods of time. The voltage regulators might be OK to deliver 90W for a short period of time but after they heat up, their performance might decrease. Severe throttling is the result.

The voltage regulators seem OK at the 45W rated TDP but start to trigger VR TDC throttling at about 60W. VR TDC throttling is severe so it needs to be avoided. I have no idea how hot the voltage regulators are getting. If there are no heatsinks and poor air flow, voltage regulators can get quite hot. Improving voltage regulator cooling might help but it might not make any difference. If the voltage regulators are not rated to deliver enough current then they are still going to be inadequate for running the CPU at 90W. Consider reducing the turbo power limits however much is necessary to avoid all VR TDC throttling.


All 10750H processors are not exactly the same. When Intel is cutting CPUs out of a wafer, some will need lots of voltage to run stable and some will be able to run 100% stable with very little voltage. The VID voltage table that Intel programs into each individual CPU is not exactly the same for all 10750H processors. The VID numbers are used by the CPU to estimate power consumption so it can manage the turbo boost function. The required voltage and reported power consumption can vary significantly from one 10750H to the next. The formula Intel uses is proprietary. No one knows how accurately the Intel reported power consumption data represents actual power consumption.

If low reported power consumption is a good thing then I guess you got lucky with the 10750H in your laptop and Vows1x was not so lucky.
Wow thats alot of info I didnt know, the laptop that I had was a MSI ge75.

That is real bad. For the tpl values, I would need to go below 60W?

And also I think at that time period, I ran a cinebench test.

It was VR throttling again so I changed pl1 to 45 and pl2 to 100. It is alright at the moment.

Yes it is. You have a powerful CPU that you cannot run at full performance because Asus decided to save some money by using some lower cost voltage regulators.

All you can do is lower the power limits as much as necessary to avoid VR CURRENT throttling. Now you know what to test for the next time you buy a laptop.

Yeah. Even I tried playing FIFA and it just slowed down. Now it VR throttles. Yesterday I put it at 45 pl1 45 pl2. Same thing. I was going to just get a desktop instead and use this for only school but what's the point when this laptop slows down so bad, using my browser and using windows in general is horrid.

EDIT - I lowered the values and it keeps the power limit throttling instantly. Then it slows down a bit. When the package power is below let's say 20W, then it runs normally. Meaning it shouldn't require much power at all so it's just confusing.

The package power is always above 45 watts even if I set pl1 and 2 to 45 each. It will be at like 60 with nothing apart from my browser running. Then the VR Current flashes red and it slows down. Pl1 and 2 start to flash as well

I managed to get it to work for a while. Had to set the maximum power state to 99% in the control panel under my power plans. It was working but till now. My CPU exceeds the power limit even when idle. I have nothing running and it's drawing 50-60 watts off the rim (It also happens immediately after I boot up the laptop, log into Windows and everything). pl1 is 45 and pl2 is 55. It was working earlier today with no VR Throttling. It will power throttle which slows the CPU down a bit but nothing too big until it VR throttles. It VR throttles for a couple of seconds because it flashes red then yellow then it stays yellow then flashes red again then it repeats.

Also, it looks like it VR Throttles (Flashes red) mostly when pl1 and 2 flash red. VR throttling on Core and Ring but PL1 and 2 are showing up on Core, CPU and Ring

That is equivalent to using the Disable Turbo feature in ThrottleStop. It is definitely a lot more than a 1% reduction in CPU speed. The 99% maximum power state setting reduces mobile CPU performance significantly because most mobile CPUs have a low base frequency and they use a high percentage of turbo boost.

Your Asus ROG laptop is not living up to the hype. The voltage regulators that Asus decided to use are either low end or they are damaged. No one should have to disable turbo boost and run their CPU at a fraction of its rated speed.

I set it back to 100%. Doesn't make a difference and you're right. It's useless to let the CPU run at half of its intended speed. I'm honestly done with gaming laptops, to be honest. I plan on getting a desktop later this month or next month. But I do plan on using the Zephyrus for school only though.

This laptop is designed to run hot anyways

No laptop is designed to run hot. Heat is literally the biggest issue when it comes to laptops, especially gaming ones.

Sounds like you and webb troubleshot to the point where your best answer would be to RMA to entire thing. But because you apparently already took it apart multiple times to apply paste they'd likely laugh that away.

Personally, I wouldn't RMA (mainly because of where I live and also if I did and I decide to, I'd just get the big fat middle finger from them lmao). I know Asus and even Razer have had a bad reputation when it comes to that. I'd honestly just look for a better brand that ticks the boxes to look for. And I said that because Webb and some other guy were talking about thermals I think. And It was me basically saying the laptop basically runs hot anyway no matter what I do. The chassis itself, looking at It you'd know instantly and also it's one of the biggest drawbacks that comes with gaming laptops. I've done an undervolt, and applied thermal paste twice (the first was the Arctic mx-5 but it pumped out so I used the ICD7 which from reviews has better longevity. Also did both the dot method and the spread method) and messed with the power limits. Cooling pads too as well but they don't make any difference realistically. But the verdict is probably production.

Even with the Liquid Metal drying up within the first year of using the laptop I think, I figured I'd have more issues in the future.

When I had a laptop with the 10750h, I never saw wattage numbers higher than 82w or so. I used XTU and hwmonitor, I dont remember 100w wattage numbers.

If your i7-10750H maxed out at 82W either you had a finely tuned undervolt or your laptop couldn't deliver 4.2/4.3GHz in full load multicore benchmarks.

I have an i7-9750H and to deliver its maximum multicore clock (4GHz all core) in Cinebench R23 without undervolt this CPU needs 100W.
With -130mV in cache and -220mV in core consumption in the same test it goes down to 60W.

The 10750H is pretty much a 9750H with slightly higher clocks and slight efficiency improvements.
Without undervolt to reach 4.2/4.3GHz all core in the same Cinebench I would bet on something between 110-120W.

And no one mentioned the elepfant in the room :oops:

I'm using the Innovation Diamond Cooling 7
I.....actually have the same laptop(not using it right now,but i took it apart at least 4 times in the past) and remember that the whole series came with liquid metal on the CPU. Poorly applied,leaking around but still...liquid metal. So you apply anything else but LM,don't expect any good results.ASUS did that on purpose,those CPU's run hot. I also remember that there was that blue paste instead of thermal pads,which took me hours to remove completely and if YOU just left it there,thinking it would do as before,here is your other mistake.
