    When I get throttled the reason for limit window says PL1 and EDP OTHER - Sometimes PL2 in yellow


    I installed XTU to increase the power limits - but still got power limit throttling no matter what - and that program made everything worse and I got PL throttling even earlier - so I uninstalled it :/

    I did some googling around and some people said it PL Throttle happens when vrms get too hot - but I don't know how to check the temps of those

    if I let the laptop sit for a while, the 1st run of cinebench doesn't throttle the cpu, but the second will for sure

    You have a locked down mobile cpu. After a short bench or load (F.eks when you run second round Cinebench R15 it will throttle down clocks due its locked TDP who is 45W).

    @beer354 - @Papusan nailed it. Here are the official Intel specs for the 8750H.

    https://ark.intel.com/products/134906/Intel-Core-i7-8750H-Processor-9M-Cache-up-to-4_10-GHz

    The 8750H has a TDP rating of 45 Watts. Long term, they are designed to run at a maximum of 45 Watts. When highly stressed, the CPU will automatically throttle to keep under this built in power limit. Have a look at the log file

    Code:
    2018-07-18  21:58:50  39.00  100.0  100.0  100.0        0   83   0.9960   65.6

    The CPU is running at its full rated speed, using the 39.00 multiplier, but power consumption is too high at ~65.0 Watts. Throttling kicks in, the multiplier decreases to ~33.33 which gets power consumption down to 45.0 Watts. Your CPU is running exactly as Intel intended.

    Edit - If you have tried Intel XTU and ThrottleStop to increase the power limits without success then there is nothing you can really do about this problem. You could try under volting the Intel GPU and System Agent equally to free up a couple of more watts for the CPU.

    The log file clearly shows what is going on. The CPU temp in the low 80°C range is just a coincidence. Intel would have more friends if they allowed the power limit to increase as long as the core temperature was still OK.

    @intruder16 - On the 4th Gen CPUs, the CPU Core and CPU Cache offset voltages do not have to be set equally. You can try going lower on the CPU Cache voltage. The PP0 Current Limit is set to 85 Amps in the TPL window and your screenshot shows that this value is locked by the bios. My Lenovo Y510P is the same. Without a modified bios, there is no way to go beyond this limit.

    The Intel turbo time limit is not well documented. You may or may not get exactly 28 seconds. You rarely get this exact value. Part of this depends on how hard you are running your CPU and how much it is over the 47 Watt TDP limit. I saw one document that compared the time limit to water in a bath tub. If you pull the drain plug, the water will slowly leak out and turbo boost will last longer. When running LinX or Linpack testing, that is more like blowing a hole in the bottom of your tub with an elephant gun. The water will leak out much quicker and the length of time turbo boost lasts will end up being much shorter. I didn't want to steal Intel's analogy word for word so that's my version of what happens. That also explains on some laptops when you run a benchmark back to back, you might end up with less turbo boost and a lower score on the second run compared to the first run. I think NotebookCheck was running Cinebench in a loop to check for performance consistency.

    It sounds like the power adapter is not adequate or you have had some awfully bad luck. I am still using my original 120 Watt adapter but it doesn't get much of a work out. I believe the Y510P with 2 Nvidia GPUs in SLI used a 170 Watt adapter instead. You might want to look into getting one of those next time your power adapter craps out. EBay has a few of them listed in the $40 to $60 range. I still like my Y510P. I would get something newer but it is still good enough for what I use it for.

    Yep, 170W, spot on. My Y500 with GT640M SLI has one of these almost literal bricks. I'd get the more power efficient and lighter 150W charger from the Y50, though

    I could actually increase the power limits but not the 45w wall, so I was able to get 70w - 75w etc but not the hard limit of 45W , it would still throttle back to 45w - so installing xtu made no sense.

    And before using XTU, my cpu only throttled to 3.6ghz @45w, now I am down to 3.2ghz @45w. I have no idea how to get that 3.6ghz @45w back - the key is to get as much performance as possible @45w

    In XTU, have you increased the "Turbo Boost Power Max"? In my case, only upping that would be enough to "change" my TDP from 15 to 28W (or whatever value I wanted)
    There's also the "Turbo Boost Short Power Max" that you can try increasing, but I guess that's the PL2 limit, not the PL1 that is tagging your logs

    Alternatively, you can increase to infinite the Turbo Boost Time Window, so it will run forever at boost speeds
    [​IMG]





    BTW check on HWiNFO the info about your CPU and Turbo power limits. Mine seems to be "unlocked", but yours might not

    You can only squeeze more mhz in those 45w by finding the max stable undervolt.

    If xtu doesn't help with the power limits, then I recommend to uninstall it, reset bios to defaults (in some cases, it is necessary to do a EC or even cmos reset to get rid of the problems that xtu can cause) and use TS to manage the settings.

    XTU is only useful for changing the power limits that TS doesn't have access to and after you change those limits, you should disable/kill the xtu service and use TS to manage the UV and other settings.

    The weird thing is I had higher volts and it maxed at 61W @3.9 or [email protected]
    Also I saw people running 3.9ghz @52 W so clearly I have a bad chip if I am doing a lot higher undervolt and using more watts

    So clearly something is not right - Before I reset the cmos I would just return the laptop and get a replacement

    I am also having other issues with it - unrelated to performance/heat

    Resetting the CMOS isn't all that hard. Just restore your BIOS to default and call it a day. (remember to check if your SATA mode is set to AHCI or whatever it was prior restoring)

    Remember that the Intel GPU also counts on this 45W limit, so if it's also running, your CPU speed will reduce so it can fit the iGPU and CPU in the 45W package limit

    My laptop has a 1060 and from what I have read it has the igp disabled, you can't use it at all - I tried undervolting the igp -70mv without any difference

    Shouldn't it be an Optimus system? Intel iGPU draws on the screen and all, and the 1060 just process stuff. The Intel iGPU should be running

    @unclewebb Finally fixed my C states issue by dirty installing windows, now C8 is working again as it should . Also my system now more responsive than before which is not what is expected.
    And little off topic but i has windows 10 1709 installed i reinstalled same version now i have windows.old folder, can i delete that if i dont intend to revert to that setup?

    Sure. I think windows cleanup tool is better suited for this, otherwise you'll end up encountering permission issues

    Also, the user folder (with documents, pictures etc) is inside the windows.old folder. Check it for your personal belongings before wiping

    You were actually right... I removed the checkbox of the lower grayed checkbox and now it seems to work correctly, but I would consider this a stupid bug of Windows. If the upper checkbox is not selected, the lower tree one should be disabled/ignored too. TS stays open/running now, even with AC/battery switch.

    I found another issue though. I noticed by accident, that on idle, package power is shown as about 1.5W and it wont go lower anymore after I had woken up the laptop from standby (S3 STR). When I reboot Windows, it goes correctly again to a lower state of about 0.7W in idle. Anyone seen this before too? Is it a Windows bug, CPU bug? Can it be solved maybe somehow with TS? CPU is a i7 8750h in Dell XPS 15.

    In regards to the package power issue, I too have experienced this. I'm not too sure what the cause is, but it has happened a few times. When it does happen, I run Windows Disk Cleanup then a full shutdown.

    My guess is something to do with Windows Defender.

    Erm...... bad guess I guess? First, why should it, second why should Disk cleanup "help" with this or be a good idea to use it in this manner, third, I use Bitdefender and it happened before Bitdefender Installation too. It seems to be a bug with C states maybe after sleep, and CPU doesnt enter lowest C state anymore? Im sure @unclewebb could say something to this issue. 1.5 vs 0.7W is a huge battery drain actually on idle.

    I looked in the C10 window of TS when this happens, and it says package c state percent c7, c8, c9 and c10 are all 0.0%. They never are used TS claims. Rebooting Windows, and it goes again to 0.6W and c7-c10 package are being displays by TS.

    I can mostly always reproduce this by going to S3, wake up, and then it's stuck at a lowest of 1.5W.

    After clean Windows reboot:
    [​IMG]

    Now going to sleep (S3), wake up, and package is stuck in C2. wont enter any lower C states anymore until Windows reboot:
    [​IMG]

    I can always reproduce this by going to sleep (S3 / STR), then it is broken until Windows reboot. Windows fast boot is deactivated. Same as hybrid sleep.

    @maffle WOW you have c10 state working that super rare ..... , even my laptop had c10 request but i have never seen it being used .
    coming to your c state problem after sleep , i had that issue after i unlocked the advanced power options using a cmd script .I fixed it by reinstalling windows with same ver and selecting the keep files and apps option so basically only windows files and setting were reset which is what fixed my problem.

    Omg wth why won't C9 work on my laptop?
    None of my cores have spend a single CPU cycle since boot in C9 or C10. C10 is disabled, TS shows that the CPU should be able to enter C9.
    upload_2018-7-22_16-20-53.png

    No fair.


    @maffle I'd say it is a BIOS issue. Poor engineering from Dell. You may be out of luck until a BIOS update. EDIT: On Page 515 or something of this thread iirc someone else was complaining of the same thing, C state would work fine until resuming from sleep.

    EDIT: Confirmed, Page 515.

    @Docktor

    I actually had disabled modern standby via bios (force S3), this will automatically bring up all power settings in Windows 10, so the issue is related to yours I guess. I never used a script or registry hack to bring up all the hidden power settings.

    I enabled modern standby again (which means also disabling S3/STR), went into modern standby and back to wake state, the switch works normally, no stuck in c2. But now I wont have S3 obviously.

    I guess your reinstallation forced you into modern standby too again? Or do you have a working S3/STR right now with no locked C2 state afterward? Your hack mostly just deactivated modern standby I guess, because all hidden settings visible is the same as modern standby off (I have no idea what moren at MS had this glorious idea).

    Just great, so it is a bios problem or maybe microcode bug of the 8750H? I guess opening a ticket at Dell wont do nothing, it would mostly take 2 months, until ticket escalates and I end in first level support, by any luck... This bug is not acceptable, I cant and wont modern standby and I want normal S3, but with this bug, it is totally useless.

    It more looks like a Windows bug to me. After S3 sleep, CPU doesn't seem to be initiated correctly or whatever and is stuck in C2.

    I have no idea what s3 or modern standy is , quick google search seems like they a power saving sleep state of some kind??? by MS .
    i have no access of these options but unlocking the advanced option probably changed these settings, so i was getting stuck at c3 after sleep.

    Your testing seems to confirm that TS is reporting this correctly. With TS reporting C10 activity, the reported power consumption is less and most importantly, the individual core temps are a couple of degrees lower. Less power consumption equals less heat. Your screenshot might be the first one in this forum that confirms C10 exists.

    It depends on the CPU. Core 2 Duo, YES. Most modern 4th Gen and up Core i CPUs, NO.

    For a question like this, why not do your own testing? In the FIVR window, set an offset voltage, hit Apply and have a look at the monitoring table in the top right corner of the FIVR window. That data is live and is being updated every second. I might have to add a clock to that table so people understand that this data is being constantly updated. Did pressing Apply change the offset voltage value in the monitoring table? Hands on testing is always the best way to answer ones questions. When you learn something new, post about it here in the forum with some pics so other users can learn to.

    It is not needed to have ThrottleStop turned ON if your intention is to only undervolt the CPU. Tested on an i7-7700hq.
    It is also possible this way to check "Disable Turbo", if you want to preserve battery life when plugged in, while having TS turned OFF.

    [​IMG]

    As you can see the Voltage decreases as soon as I hit apply, given that you selected "OK - Save voltages immediately". ThrottleStop was OFF (green icon).

    That is a decent undervolt you getting on your i7 7700HQ. How are your idle and gaming temperatures??

    I wish I could go over -100mV with my i7 7700HQ to be stable. Max temps I'm getting are 82 c when gaming GTA 5 or Far Cry 5

    Hi, I use Acer E5 576G, it has 8250u, but I cannot understand. I change RW, Throttlestop, but it stuck at 15W. Can you help me. (sorry for my English). When I use XTU to stress test, it says "power limit throttling".
    I use windows 10 1803. The CPU stay at 3.4 a short time.

    The screenshot you posted shows that ThrottleStop is still set to 15 Watts.

    [​IMG]

    Try changing 15 to 25 and see if that makes any difference.

    Do you still have Intel XTU installed? It has services running in the background that can interfere with ThrottleStop. If you are still having problems, I would completely uninstall XTU and shutdown your system. Do not use hybrid restart. Do a full shutdown and make sure that the CPU gets reset to its default settings.

    The Intel monitoring app you are using also shows that the PkgPwrLimit0 is set to 15.0 Watts. I believe that this value is the PECI value. ThrottleStop cannot change this one. It is a third power limit that is sometimes used. The CPU will use the lowest of these 3 limits.

    When using Speed Shift, for maximum performance when testing, try setting the Speed Shift - EPP value to 0.

    To see throttling reasons when Intel XTU is not installed, click on the ThrottleStop - Limits button and look at the Limit Reasons data. Exit HWiNFO when using Limit Reasons.

    Edit - Very unusual to see two different monitoring apps in total agreement. I guess my decision to follow the Intel recommended monitoring procedures was a good idea. You can trust the ThrottleStop data. :)

    Thank you for your help, but when i setup as your guide it's still throttle.
    I uninstalled XTU (included remove user settings).
    Set Power package limit to 25.
    1st test I set Speed Shift - EPP value to 0 and 2nd test I didn't select this option.
    It's still throttle.

    @LockonDyns - ThrottleStop shows that your CPU is throttling because of the 15 Watt PL1 turbo power limit. In your above tests, did you use RW Everything and make sure that FED159A0 and FED159A4 both ended in 8100 like before?

    If ThrottleStop + RW Everything cannot get you beyond this 15 Watt limit and Intel XTU cannot get you beyond this limit then there is nothing that you can do. Some manufacturers will let their laptops go higher than 15 Watts and some manufacturers do not allow this.

    Also, it is useful to set the lock bit mentioned in this post, http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/page-812#post-10758751, and some replies of mine at that following posts.

    BTW, although it is not the current issue you faced now, the new 7th/8th CPU, remember that the GPU and System Agent offset voltage must be set as the same in order to take effect the offset voltage on GPU.

    My idle temperatures are awful, around 50 degrees Celsius. I have a GL702VM which is awful when it comes to cooling, I wish I could edit the fan curve for a better cooling but so far no luck. While gaming on the other hand the CPU never exceeds 80 degrees Celsius. And while doing "not so heavy" gaming it hovers around 70 degrees.
    However I was only able to achieve this kind of temperatures due to a combination of procedures, which were lifting my laptop, replacing the thermal paste with liquid metal on both the CPU and GPU (made a nice difference on the temperatures while under load), looking inside the laptop and check what could be blocking the airflow, sealing the air gaps between the fans and the heatsink, and of course undervolting the GPU (using afterburner) and the CPU.

    Also, -100mv isV is way to little for a i7-7700hq, are you undervolting the Core and the Cache by the same amount? From my experience you should decrease them equally. And don't touch the other parameters, even Intel GPU, as they don't do any difference.

    I cannot set bit lock (set FED159A0 to 1?) It's auto return to 0.

    I believe the lock bit is the highest bit, Bit[31], in FED159A4. This bit locks both FED159A0 and FED159A4.
    I do not believe that this setting is your main problem but it never hurts to try different things.

    i looked and looked, but cant find guide, and afraid to tinker too much with settings, not knowing what they do. Does anyone know how to set max boost speed on CPU, or can someone point me to a guide?

    When ever my cpu starts boosting to 3.9 ghz during gaming, its just a matter of time before the system throttles. Those boosts heat the rest of the comp up, so the comp throttles the cpu down to 800 mhz. When i disable turbo boost, the base clock is 2.2 ghz, and there is no throttling.

    So i was thinking to set turbo boost to a max of 3 ghz, instead of the native 3.9 ghz, and see if system can stand up to prolonged workload under these limits.


    BTW. undervolt of -170 mv has reduced my cpu temps by 18C, so very grateful :)

    @zeverus - Why no pictures? How can I help you out and make recommendations if I have no idea how you have ThrottleStop setup?

    In the FIVR window, are your Turbo Ratio Limits unlocked and adjustable?

    [​IMG]

    If unlocked, you should be able to lower those values to lower your maximum multiplier.

    If you are seeing 800 MHz, this is often times caused by having the BD PROCHOT function enabled. Have you disabled that yet?

    If your cooling solution is not capable of dissipating 45 Watts of heat and you have a 45 Watt CPU then shame on the manufacturer that built your laptop. What laptop model do you have? People need to know. Instead of reducing the turbo multipliers, it would be better to reduce your long term turbo power limit to maybe 40 Watts or 35 Watts or whatever is necessary so you do not exceed the capabilities of your less than adequate cooling solution.

    Lowering the multipliers will lower your performance ALL of the time. Lowering the turbo power limit will only lower performance when necessary.

    I can change my 8550u TDP from 15W to anything I want on XTU. It's just a slider.
    However XTU says it must restart before changes are applied. This is a single-time restart, after that, I can freely change my TDP to whatever I want, on the fly.

    I used to open XTU, set it then close it forever, until the computer crashes or I have to force shutdown it for whatever reason. XTU then resets the TDP back to stock.
    Now I just use a small command on Task Scheduler to always set the TDP to my desired value (28W) every time I log on

    idk if XTU closed still affects something, but I think it's a good tradeoff to have control over my TDP.

    I have dell XPS 9570
    i7 8750h, 16 ram, 1050 ti max q and a 97 whr battery.

    There is this sensor in hwinfo that is called "dimm" and when ever that hits 63 C it throttles my cpu down to 800 mhz.

    Undervolt -170 core, -160 cache, -75 iGPU lowered my cpu temps from 90 to 72 under full load. But as soon as that dimm sensor reads 63 C it throttles cpu. When i disable turbo in your program, it never hits the 63C.

    When i run prim95 comp stays pretty cool at roughly

    Should i try and just lower the turbo ratio limits until i achieve something sustainable?


    upload_2018-7-23_20-4-7.png

    Its my first ever undervolt, and it worked like a charm! Thank you for great program, and thanks for fast reply.

    Only disabled the BD PROCHOT now after seeing your post. In the undervolt guide i followed, it didnt tell me to disable that option.

    Temps stays acceptable during prime95, but as soon as i play games, it starts to throttle the cpu after some time, if i allow the cpu to boost. I heard others say the throttle starts because of a 'dimm' sensor reaches 62-63C, and it seems to be the same on my system.

    I can live without a 3.9 ghz cpu, but anything over 3 ghz would be nice

    @zeverus I honestly don't see or understand, what your goal is or what your expectation is to the laptop. If it throttles, then it throttles. DIMM sensor throttle should just happen under rare extreme situations. What do you want to run on the laptop, which doesn't work? a 24/7 seti@home? Your logical reasoning doesn't make any sense. What do you want to do with the laptop, what doesn't work? Your undervolt settings are way too high btw, I doubt that it runs 100% stable with that. The XPS isnt a gaming laptop. Cap your FPS at 60 or enable vsync, disable AA and shadows, set game settings to low, disable turbo boost (you dont need it for games, it will run 2200MHz which is totally enough for gaming), and it should run fine for most games. And if you have 4k display, you have to play in 1080p obviously.

    I want a discreet windows laptop (everyone i work with has mac, and i don't want to call to attention by having PC). A fast laptop that can run MS office and browse web without having fans go on. And a laptop that can pull a game or two when i'm alone, where i dont mind fans going mental.

    1080p, disabled turboboost, still getting a little CPU throttle down to the 800 mhz every now and then. Running game: total war warhammer 2 (cpu intensive game). Undervolt is stable - No issue with 7 hour prime95, and no issue punishing my laptop with 5 hour gaming session (except the cpu throttle every now and then).

    After last gaming session i get cpu max 87, gpu max 75, but some ambient sensor is saying 121C, and the bloody dimm sensor is hitting 63C and forcing the cpu to throttle.

    considering returning laptop, but i don't see anything else on the market that fits the bill, except macbook pro, which is double price, iOS, and appears to have throttle issues as well.

    @zeverus - When your laptop is completely idle, without Google Chrome or HWiNFO or anything besides ThrottleStop running, what C0% does ThrottleStop show? This should be under 1.0%. Your screenshot shows a crazy high C0% like something significant is running in the background full time. With multiple tabs open, it could be anything.

    For the 8750H, the CPU Core and CPU Cache offsets have to be adjusted equally. The Intel GPU and System Agent also have to be adjusted equally. If you offset the Intel GPU and you do not offset the System Agent equally, the Intel GPU under volt will not work.

    Yes, that is one option. Do not check Disable Turbo. Change the Turbo Ratio Limits from 41, 41, 40, 40, 39, 39; to all 36 or all 30 or any magic number you can dream up. The other option is to leave these alone and only change the Package Power Long in ThrottleStop. If your heatsink cannot handle a 45 Watt CPU while the Nvidia GPU is being used then lower this to 40 Watts or 35 Watts.

    Before doing the above, how about do some testing for me so I can see first hand the problem. Turn off HWiNFO, disable BD PROCHOT, in the ThrottleStop Options window enable Nvidia GPU monitoring and check off Add Limit Reasons to Log File. Go back out to the main ThrottleStop screen, check off the Log File option and wait 30 seconds so ThrottleStop can gather some baseline idle data. Now you are ready so start up a game. Play for at least 5 or 10 minutes so I have a reasonable amount of data to look at. When finished playing, exit your game and exit ThrottleStop so it can finalize the log file. Go into the ThrottleStop Logs folder and upload your log file somewhere convenient. You could also just Copy and Paste the data to www.pastebin.com and then post a link so I can have a look. The CPU should never drop to 800 MHz so I would like to see this in action.

    Edit - For an alternative, maybe the Lenovo Legion Y530 would work better without the issues that your Dell is having. Same 8750H with an Nvidia 1050Ti and similar price point. Looks like a little more thought went into the cooling system.

    The answer on your problem is still listed below aka last in first page Dell XPS 15 9570 benchmarks + temps thread

    I am also highlighting in red areas that I consider troublesome.

    DIMM throttling:
    So the 9570 has issues with DIMM temperatures. Once it measures above 62C it throttles the CPU to 800MHz. Putting thermal pad between the ram and the case helped me to avoid throttling but there isn't much headroom. Other users are cooling the sensor itself to avoid throttling.

    Check out abujafar's findings:
    http://forum.notebookreview.com/thr...benchmarks-temps.817970/page-29#post-10767160

    The very best advice you can get... Return it for refund. Why accept this mess?

    I idle between 28 and 36 C degrees but on load with far cry 5 and GTA 5 I hover around early to mid to late 70's c Degree. I repasted with Gelid GC Extreme on both CPU and GPU. I only undervolted the CPU as the Max GPU temp I'm getting is 64 C degrees. My fan curve is also bad with my laptop, I have the HP Omen 17 with gtx1070 graphics.

    I only undervolted the Core and Cache but only use the same value which is -90 mV for both. If I decrease it more it seems unstable as it my FPS is reduced while gaming.

    Hello guys, I've heard a lot about Throttlestop, but I don't understand it so well as to set it up myself, I have Lenovo y50-70 with i7-4720HQ it throttles sometimes when I play gta 5 and I wanted to try using this to try and get better performance, could anyone tell me how to set it up for this processor? Thank you very much

    Thank you so much for taking the time, its really nice of you!

    I will do your test tomorrow, and do everything you said.
    prior to everything i did, i adjusted core and cache undervolt to -169.9 for both options. I also set igpu and system agent to -60.5. and left 'disable turbo' and BD PROCHOT unchecked.

    With as many programs turned off as possible, the C0% ballances around 2-3. going down to 0.x but spiking momentarily up to 5-7, just for a few seconds. dancing back and forth.

    I first ran with nothing on for 30-60 seconds. Then i turn on msi afterburner, steam, hwinfo, and then launch game: total war: warhammer 2.

    cpu throttled to 800 mhz a few times, but recovered its speed relatively fast.

    I'm going to keep it. What i need is a slim and light 15 inch laptop for browsing and MS office, that will stay silent, have a decent battery, and handle a good few browser tabs without a hassle. The fact that the xps can handle some games is just a bonus, but not a requirement.

    with nvidia gpu disabled, the xps covers my primary needs - and it's only the thickness and weight that make it less appealing for my dream machine.

    Intel U processor would be fine, and i don't need a dedicated gpu. I was considering a zenbook 15", ideapad/thinkpad 14"/15", MS surface 13", macbook 13". I got a 33% discount on the XPS, so all the other computers in the same price range come with 4-8 gb ram and 128-256 gb ssd and slower cpu's. The XPS i got was with 16 gb ram and 500 gb ssd, and better CPU. The faster cpu and gtx 1050 is just a bonus that wasnt a requirement for my needs.

    If you can recommend a different laptop that can compete with the XPS when in silent mode, in the same price range (or cheaper) with at least 250 gb ssd, 8 gb ram, that's slimmer and has a longer battery life, i would appreciate it.
