Constant "EDP Other" under RING in ThrottleStop

[unclewebb]

You set the PL2 short power limit to 30W so your computer is power limit throttling at 30W. It is doing exactly what you told it to do.

Update to ThrottleStop 9.4 and set the TPL window so it looks like this. Power Limit 4 should be set to 0.

PL2 should be at least 60W, not 30W.

The Intel TDP power limit rating for an 8750H is 45W. Some manufacturers like Acer like to enforce this limit.

You can try setting PL1 higher than 45W in ThrottleStop but during a long term stress test, it will likely still power limit throttle down to 45W. That is what PL1 and PL2 lighting up red in Limit Reasons means. Power limit throttling. When this happens, EDP OTHER will also light up red under the RING column.

Clear the BD PROCHOT check box on the main screen of ThrottleStop.

There is no need to undervolt the core and the cache equally. Keep the cache at -120 mV and try setting the core to -175 mV or higher. Test with Cinebench to see if using different voltages improves performance or temperatures.

i did everything as you told me and I think it helped me there is no more power and TP2 red limit... thank you ! and one more Question: can i lower temps without Disabling Turbo Boost?

Hello, I have read almost everything on the topic, I have watched a lot of guides in which most people generally have no idea what they are doing with TS, I obtained very stable benchmark results using trial and error. The problem is that PL1 is detected at some strange moment, it normally writes that it consumes 70W and the processor then has a maximum of 72C, suddenly the clock speed drops to 3.7Ghz and the power drops to 65W. I lowered the CPU Core by -160mV and the CPU Cache by -125mV because here the results were the best, further change made the situation worse or errors occurred during TS Bench. Changing PL1 PL2 in the program probably doesn't do anything because I can't exceed the 70W limit, but when I started searching the BIOS, I found a lot of settings regarding limits, etc. I changed the limit, but it doesn't seem to help, when I blocked the CPU OC and set the power limit, it consumed over 100W up to I was afraid that the processor would melt ^^. What can I change to still all time have 4Ghz? I pushed the RAM memory to the limit and the only hope is the CPU .

That drives me crazy too. Every 15 year old with a YouTube account is an expert.

Did you try increasing Power Limit 1 in the ConfigTDP Nominal section? Try setting that to 70000 or 75000 instead of 65000.

Did you try increasing the Platform Power value?

when I blocked the CPU OC and set the power limit, it consumed over 100W

You cannot overclock a 9750H. What setting did you change to block the CPU OC?

Did ThrottleStop report over 100W? I cannot remember seeing a 9750H at that level.

Intel mobile CPUs are very similar to their desktop CPUs. People have overclocked similar desktop CPUs and run them at over 200W without any issues. As long as your CPU is not overheating, it should be safe if you can find a way to run it at a higher power level.

Some laptops use an embedded controller (EC) to enforce a long term PL1 power limit. The EC power limit is separate from the MSR and MMIO power limits that ThrottleStop has access to. If the EC PL1 power limit is programmed to 65W, there may not be a setting available in the BIOS that lets you get beyond this limit. In that situation, I would try setting IMON Slope to 50. This might help. It basically tricks the CPU into reporting half as much (50%) power consumption compared to actual power consumption. This trick might get you beyond the 65W limit. If the CPU gets up to 80W, it will only report that it is at 40W so it will not have any reason to power limit throttle. Watch the CPU temperature when playing with this setting.

I have never tweaked a recent laptop with an unlocked BIOS. You might have to search YouTube for a real expert.

I changed the settings and saved, when I turn off the laptop it will go back to 65

You cannot overclock a 9750H. What setting did you change to block the CPU OC?

CPU Lock Configuration > Overclocking lock [ Enabled ]

Exclusive TS ability to Undervolt. If there is nothing in the program, all devices revert to utility devices.

As long as your CPU is not overheating, it should be safe if you can find a way to run it at a higher power level.

It then reached about 92°C+ and throttled. After blocking OC, it is not possible to change anything in TS except power limits.

If the EC PL1 power limit is programmed to 65W, there may not be a setting available in the BIOS that lets you get beyond this limit. In that situation, I would try setting IMON Slope to 50. This might help.

Where can I find this parameter?

 

[unclewebb]

Where can I find this parameter?

That is the problem. I do not know how to find or change the EC power limit. If the EC power limit is set to 65W long term then you might be stuck at 65W max. Usually the only way around this limitation is to change the IMON Slope value.

This is how we finally managed to maintain full 4Ghz clocks while working under load. I set Imon Slope to 40 and currently it shows a maximum power consumption of 38W. I will reduce Imon to about 10-20 to have a safety margin just in case. The temperature when running Cinebench R20 does not exceed 73 degrees on the warmest core. Currently I will try to fight and block 4.5Ghz clocks on all cores under full load. I wonder if it will work . Thanks UncleWebb

Hi folks,
I have been trying to undervolt my legion i7 with i9 13900hx with some success, although still hit 93-94 degrees when playing.
But i cant get rid of these EDP OTHER limits. While idle, RING is constant yellow and when testing with Cinebench both RIGN and CORE are flashing red.
Haven't attached a screenshot for the other FIVR controls but they are: CPU P Cache -120.1, Agent -49.8, GPU -15.6, CPU E Cashe -50.8

Would appreciate if someone can tell me what i am doing wrong and how can i fix it.

Many thanks.

 

[unclewebb]

@Lolshaze
Try setting IccMax for the P core and the P cache to the max, 511.75. Set Power Limit 4 to a value of 0.

Edit - Setting IccMax to 255.75 was correct for 11th Gen and older CPUs. Setting IccMax to 511.75 is correct for 12th Gen and newer.

 

[ranoutofnameideas]

hi. i was trying to fix these throttle limits since i cant seem to find the solution.
as the screenshot shows, im running an intel Corei7-1065G7 and ThrottleStop v9.7.2.
The ring EDP is flashing between yellow and red, the others are staying yellow.

thanks

 

[unclewebb]

Post a screenshot of the FIVR and TPL windows so I can see your settings.

ok

 

[unclewebb]

Try setting IccMax to the max, 255.75, for both the core and the cache. Set Power Limit 4 to the max, 1023. That is about all you can do for EDP throttling issues. Some EDP problems cannot be solved.

Try cleaning out your laptop and replacing the thermal paste with Honeywell PTM 7950. Thermal throttling seems to be limiting maximum performance.

 

[Omgeez]

To all the guys struggling with throttling:
TLDR try honeywell PTM7950 thermal pad on CPU and GPU. I got -20'c and i tried a lot of different stuff.

some time ago i purchased used hp laptop with 8300h and 1050, i was like ,,yeah it may serve as portable console with emulators, plus it has only 1050 so probably it wont overheat" xD
It missed 2 buttons on keyboard, chasis had a crack that was not in the description, a small ghost on the screen so in the end i negotiated the price from about 140$ down to about 75$
And of course it was thermal throttling, so i was like WELL I GUESS NOBODY REPLACED THERMAL PASTE FOR 5 YEARS SO THATS NORMAL.
And when i unscrewed bottom cover i noticed that cpu/gpu radiator is missing 1 ,,arm" that's supposed to hold the screw around CPU... so i ordered whole replacement radiator on aliexpress for ~20$.
Next i had to use mini dremel tool to cut few screws cause they were impossible to unscrew. it was a horror, someone really didnt know how to handle a friggin screwdriver ;p
I put some kryonaut thermal paste on both cpu and gpu core, screwed the radiator on and booted the thing.
I tested temps with witcher3, and well it was still throttling, going over 95' and throttling....
So i was like WELL MAYBE THAT THERMAL PASTE WENT BAD, so i purchased some arctic MX4. Replaced thermal paste again. Guess what? Still throttling.
Then i ordered some thicker thermal pads for gpu vram and i used some copper shims on cpu and gpu. I did that because some time ago it helped my 2060 super drop temps by about 10-15c and it actually made it stop throttling. Still throttling.
Of course in between all these actions i messed around with throttlestop, and till today i had my laptop set to 34x speedshift max and -0.125v on core and cache so it wouldnt throttle with some kinda light gaming. So things were kinda shitty...
Until today.
Today i received honeywell PTM7950 thermal pads as i noticed on yt that some it guys were using it and i decided to put them on cpu and gpu.
The installation process is totally dogshit as its very thin, i had to reapply it 3 times so it looks somewhat ,,flat" and acceptable.
I turned on laptop, played some semi-light game - and holy shit temps actually dropped. Now. When its already getting hot outside.
I turned on witcher 3 with 40x speedshift max (default)
Yep. It doesnt cross 75'c. 98-99% gpu usage so i guess cpu is getting bottlenecked by gpu now.
i turned off undervolt 0.125v. Its 81c max
And so i kinda dont know why it worked, i tested so many different things and the results were crap. I changed thermal paste so many times i lost the count. Different pastes, different spread methods, copper shims, replaced bolts... nothing helped.... and ptm9750 fixed it...

...And everything would be great and the story would end here if i wouldnt notice im getting PL2 throttled right now XD at least in heavy games... and i have some questions:

1. is PL2 throttle a big deal?
2. Is it worth alleviating it when your gpu runs at 99%?
3. How to approach fixing it?
4. is it normal for a cpu to take only 26watts during gaming?

Thank you for your Throttlestop program, its really useful and you're the MVP.

 

[unclewebb]

Many HP laptops will limit 8th Gen CPUs to the Intel default TDP. That is 45W. Post a screenshot of the TPL window so I can see how you have it setup.

i turned off undervolt

Why would you do that? Undervolting reduces power consumption. That reduces the chance of power limit throttling. Less voltage is less power which creates less heat.

is PL2 throttle a big deal?

It is not too big of a deal. Many laptops power limit throttle. Most people do not closely monitor their laptops so they might not know or care when their computer is power limit throttling.

How to approach fixing it?

You can try increasing the MSR turbo power limits in the ThrottleStop TPL window. Also check the MMIO Lock box. If this does not solve the throttling at 45W problem then I guess you have to live with it. Many HP laptops program an embedded controller EC to enforce the 45W limit. ThrottleStop does not have access to the EC limit. You might not be able to go beyond 45W during any long term test.

is it normal for a cpu to take only 26watts during gaming?

It depends on the game. Most games are not going to work your CPU as hard as a full load test like Cinebench does. If your CPU is running at full speed then that is as good as it gets.

When you post a log file try using the code and /code html tags before and after the log file data. This maintains the formatting which makes it a lot easier to read the data. Put the code tags within [ ] square brackets with no spaces.

You can also just attach the log file as a .txt file. That maintains its formatting.

ptm9750 fixed it...

Thanks for confirming that. I keep preaching to people to use Honeywell PTM 7950. I do not know if it is the best but it works quite well on mobile CPUs. Next time try putting it in the fridge or freezer for a little bit. I have heard that trick can make it easier to work with.

Thank you for your ThrottleStop program

You are welcome!

 

[Omgeez]

Why would you do that? Undervolting reduces power consumption.

Just to see how much it would heat in ,,default scenario" without any additional apps like Throttlestop. Of course i turned it back on after test

Why would you do that? Undervolting reduces power consumption. That reduces the chance of power limit throttling. Less voltage is less power which creates less heat.

Lmao for a while i thought that "power limit" might mean its power limited - not getting enough power MAYBE BECAUSE of undervolt ;p i noticed it still appears though after disabling undervolt ;p

You can try increasing the MSR turbo power limits in the ThrottleStop TPL window

I tried messing with these for few hours now, and im just going to leave it as it is, im not sure if it affects anything tbh, launched cinebench to see what happens when cpu is at 100% usage, got some pl1 throttling but still it ran at 100% usage and 100% clockspeed so i guess its ok

And now that i got some thermal headroom i tried some overclocking on gpu, turns out GPU effective clock is kinda locked in sync with voltage, so i just increased clocks without undervolting, still it doesnt go beyond 75c with nice +300mem +175core ;p

I keep preaching to people to use Honeywell PTM 7950. I do not know if it is the best but it works quite well on mobile CPUs.

Yeah Man its like magic, -20'c just like that, it makes gigantic difference, saw some techtuber say it might work better on processors without IHS (he tried it on regular desktop cpu and got pretty much same temps as with mx4). Im happy i didnt give up and didnt go liquid metal route.

Again, thanks for Your help, Your app is amazing.
