Throttlestop problem EDP OTHER and PL 1

[ChromeG]

Hello,i also am experiencing throttle or red bars on PL1 and PL2 and cant have a stable fps on fortnite meanwhile i can push and maintain 120 for 4 minutes or so and then cpu starts to go to drain 0.40ghz.What can i change to maintain a decent fps? Thanks

@ChromeG - What laptop model do you have? Turn on the Log File option in ThrottleStop, play a game for at least 15 minutes and then attach a log file to your next post. It will be in your ThrottleStop / Logs folder.

Your screenshots show that you have disabled half of your CPU. Did you do this on purpose? In the BIOS make sure hyper threading is enabled. Run msconfig, go to the Boot tab, press Advanced options... and make sure the Number of processors box is not checked. If your CPU gets too hot when it is fully enabled, redo the thermal paste and try to fix the cooling problem.

You can also try using the Lock option in the Turbo Boost Power Limits section. If your CPU is getting locked to 0.40 GHz, I am going to take a wild guess that you have a Dell laptop. Some of their laptops use the EC to set the turbo power limit internally to 0. This forces full on CPU throttling down to the minimum speed.

Check the TDP Level option and set that to 0. A setting of 1 forces a low power U CPU into low TDP mode.

i attached folders as you said,couldnt run a game because of corrupted game files which i will fix but i ran a cpu burner on 12 threads and got a max of 87C which has never happened but the cpu was kind of stable and a little throttling is happenning since core has edp other and pl1,pl2 and also gpu and ring has edp other on yellow and when i run a game or a burner core pl2 and edp other ring turns red.If anything other needed please list them and ill be happy to send,thanku very much!

also regarding my laptop its a Lenovo Thinkpad T590 with 16gb ram and nvidia mx250

Lenovo Thinkpad T590

Your log file does not show your CPU running at 0.4 GHz. When it is loaded, it starts to power limit throttle at about 22W and runs at 3.2 GHz to 3.4 GHz. That is completely normal for a CPU that has a 15W TDP rating. Better than expected.

Check the FIVR - Disable and Lock Turbo Power Limits box. On any Lenovo laptop, I would also check the Options - Lock PROCHOT Offset box. Some Lenovo software will change the PROCHOT Offset value while you are using your computer. It is best to lock PROCHOT Offset to a fixed value.

After you do this, run another log file while gaming. A 12 thread CPU burner test is overkill. It can overwhelm a laptop with a 15W CPU.

 

[ChromeG]

Everything you said is done, now i will run a game and see how it performs and trust me bro it goes to 0.8ghz when im gaming and 1.2 is max im playing fortnite btw and i can maintain 120 fps if it goes to 2ghz or 60 at 1.2ghz..

Also what i did is set a multiplier to 40T but the pc crashed after a long gaming session..

Your screenshot shows that you have Speed Shift Technology (SST) enabled. When SST is enabled, the Set Multiplier setting does not do anything. It is not used so do not check this option.

When you undervolt a computer and it crashes, that is usually because your voltage setting is too aggressive. Try using -50 mV or -60 mV instead.

I am sure you have a throttling issue. A log file will show what is causing this problem.

 

[ChromeG]

I will manage to get a file,now the cpu and gpu thermal goes red and my fps spikes while on 60-70C

 

[unclewebb]

@ChromeG - Did you check the Lock PROCHOT Offset option yet? This is a must on Lenovo laptops.

Is that just too hot or bottleneck

@ChromeG - Did you check the Lock PROCHOT Offset option yet? This is a must on Lenovo laptops.

i locked it at 0

 

[unclewebb]

Is that just too hot

Show me a log file while gaming and I will let you know. If it shows that your CPU is constantly thermal throttling then I guess you are going to have to reapply the thermal paste or fix the cooling somehow. Have you ever done any maintenance on your laptop? A good cleaning?

 

[ChromeG]

I have not because the laptop is new and runs well i just want to undervolt it to get a bit more fps

there is the log file,temps and all are fine just when im charging on capped 120 fps it hitches to 30-40 and when im not charging i get a constant of 60 no drops decent.

 

[unclewebb]

all are fine

Your log file shows that your CPU is running slower than it should be running. Your temperatures are good. I would try switching to the Windows High Performance power plan. After that, you can manually set the Speed Shift EPP variable to 80 or 84 if you want your CPU to slow down when lightly loaded.

When using the Windows Balanced power plan, I would not check the Speed Shift EPP option. Use the Windows power slider in the system tray to manage the EPP value. You can look at the monitoring table in the FIVR window at any time to see what EPP value the CPU is using. An EPP setting of 128 or greater reduces maximum CPU performance. In your original post, it shows that Speed Shift EPP is at 204 which will definitely kill maximum performance.

Hi, my laptop is Acer Nitro 5 i7-8750h with a 1050ti. I keep getting throttled because of the PL2 then PL1 but temps are normal since i got liquid metal already. Could you have a look?
Also how should i set my CPU cache offset voltage?
I saw one of the previous thread you suggest changing PP0 current limit but I cant seem to find that option in this newer version (9.3), should i tweak it and how?
Thanks in advance!

Power limit throttling and thermal throttling are two different things. Good temperatures do not matter if your computer is power limit throttling.

The 8750H has a 45W TDP rating.

Acer has decided to enforce this 45W limit. Many manufacturers allow you to go beyond 45W. Acer does not allow this. Your are stuck at 45W and there is nothing you can do. The settings in ThrottleStop are ignored when a manufacturer sets a hard limit of 45W. Acer has set this power limit internally and ThrottleStop cannot access it.

POWER STATUS CHANGE

If you are wondering why your log file has all these notices, it is probably because your computer has been set to only charge your laptop battery to 70% of its maximum charge. I like keeping my laptop battery fully charged so it is ready to go when needed. Manufacturers came up with this 70% stuff to reduce any warranty claims. I would rather buy a new battery than have some software constantly monitoring my battery and adjusting it every 5 seconds. Find out how to turn this feature off if you want to get rid of those messages.

TS 9.2 used to call Power Limit 4 the PP0 Power Limit. This was the wrong name for this limit.

TS 9.3 shows the correct name, Power Limit 4. Your screenshot shows that you have this set to 200. That is great. Nothing to worry about.

It is the internal PL1 turbo power limit that is causing the throttling.

 

[mycpuisburninglolol]

ahhh so that's why it could never go above 55W. Do you have any suggestions for having a stable clock speed? The log file (start at 11:45) is when I'm playing games and it is a little bit annoying when fps drops. I'm thinking of maybe reducing the FIVR turbo ratio limit.
Also about the POWER STATUS CHANGE I have no idea which software could cause that cuz my battery still shows 100%, any thoughts?
Thanks for answering!

 

[unclewebb]

It looks like PL2 is hard coded to 56W and PL1 is hard coded to 45W. The Intel by the book recommendations are to set PL1 equal to the 45W TDP and to set PL2 25% higher. 45W + 25% = 56.25W so those settings make sense. No easy way to get around these limitations.

stable clock speed

Use the Windows High Performance power plan and if you have to, use ThrottleStop to force Speed Shift EPP to 0. Check the FIVR monitoring table to see what EPP value the CPU is using. It looks like you will need to run the CPU at ~3300 MHz to avoid PL1 throttling at 45W. Overall performance will be worse but the CPU will run at a consistent speed if that is what you are trying to accomplish.

I would avoid using a Speed Shift EPP setting of 128. Set EPP to 80 if you want your CPU to slow down when lightly loaded. For most recent computers, you do not have to check the Speed Shift EPP option in ThrottleStop. If you use the Windows Balanced power plan, there will be a slider in the system tray that you can adjust. When the power slider is set to Best performance, Windows usually sets EPP to 84. That is a good compromise for most laptops.

POWER STATUS CHANGE

Usually when I see those messages it is because of some battery power management software trying to keep the battery at a perfect level of charge.

At 11:52:23, there is one of these messages and then it shows that your battery starts being charged while gaming. That is odd if your battery is already fully charged. These messages go away for a while and then they start again every 5 seconds. That does not appear to be normal. Not sure if this indicates a problem with your battery. It is probably nothing to worry about.

 

[mycpuisburninglolol]

Try your 3300MHz with EPP 80 and it works like charm. No throttle happens during my gameplay and a higher Cinebench score.
About the FIVR monitoring table sorry I couldn't find that option in the Turbo FIVR Control so I couldn't check the EPP that cpu is using.
I notice after a long session of gaming my battery sometimes dropped down a few percent tho being plugged in all the time so I guess that's the reason for the POWER STATUS CHANGE
But anyways I have a stable 60-80 FPS while gaming and that's all I need. Thanks for helping me!

 

[unclewebb]

a higher Cinebench score

With good cooling and unlocked power limits, the 8750H can score over 3000 points in Cinebench R20. Keep that in mind next time you go laptop shopping. There is a wide variation in performance even when the CPUs are identical. It all depends on how a manufacturer sets up their laptops and what they lock down.

I couldn't check the EPP that cpu is using.

With my magic red marker, let me help you find the Speed Shift EPP value in the monitoring table.
Maybe you have been playing too many video games.

 

[mycpuisburninglolol]

oh, thanks for pointing that out xD, I look everywhere except that graph xD.

I've seen other posts on this forum that have the same CPU as mine with a way higher score and it's not Acer. So I guess Acer is the only brand that locks the limit or is it just my model?
Also, how did you know that Acer has lock the power limit? Did you find it on their website?

When I bought this laptop a few years ago I have almost zero experience with computer stuff but in a hurry cus I need one for school work. Should have done more research xD.
Also, do you have experience with Acer laptops cuz I had a really bad time with my model (monitor died, bad thermal, BIOS has password tho I never touch it). Thinking of ditching Acer in the future.

 

[unclewebb]

Thinking of ditching Acer in the future.

Based on your experiences, that sounds like a wise decision.

how did you know that Acer has lock the power limit?

Acer locks the turbo power limits to the TDP on many different models. Not just yours. Lots of manufacturers do this. Not just Acer. No manufacturer ever admits to locking down their laptops and most review sites never mention this limitation.

The only way to find out is to do some hands on testing. If you set the turbo power limit to 60W in ThrottleStop and you check the FIVR Disable and Lock Turbo Power Limits option and your CPU still throttles at 45W, that means it is locked. If it was not locked, it would go up to 60W or higher when fully loaded. An 8750H with good cooling and unlocked power limits can use the full 39.00 multiplier during an entire Cinebench R20 test. Zero throttling. With locked power limits or poor cooling, this is not possible. Your Cinebench score immediately indicates throttling.

Now you know what to look for next time you buy a laptop. You paid for a laptop with a 45W CPU and it does run at 45W so Acer is not doing anything wrong. It is just that there are other laptops that run a lot better with the exact same CPU. You need to hunt around the forums and do lots of research to find out what different laptop models are capable of. Most consumers only look at the CPU model. If two different laptops both have an 8750H, people automatically assume that performance must be equal. This is definitely not true.

Hi, Unclewebb first thanks for making throttlestop it really help alot. I'm getting some micro stutters when playing at fortnite. And i've done some tweaks with throttlestop. Please can you look at my settings and log? my laptop is an HP OMEN 16 from 2016 with a GTX 965m and I7 6700hq. Thanks in advance
