    If Cooler Master Maker Gel Nano pumping out for you, then use thicker paste as ICD or Phobya Nanogrease Extreme. Thermal pads from Gelid/Arctic for the rest (soft pads).

    I am currently struggling with the PP0 current limit on a Dell Latitude 5290 2-in-1, which is throttling after several seconds to 18W.
    After some guesswork and fiddling with Throttlestop, this seems to be due to the PP0 current limit.
    Unfortunately, the setting is locked in Throttlestop and being shown as 71 - which, assuming a divider of 4, results in 17.75W and closely resembles the 18W reported by Throttlestop.
    (Deleting the ini and doing a cold boot does not unlock the setting)

    I have since found the thread http://forum.tabletpcreview.com/threads/dell-venue-11-pro-i5-overclocked.65020/ and have tried my luck with IFR and the EFI Shell.
    However, the "VR Current Limit" in "Core/IA VR Settings" is already set to 0x0 (= auto, should not throttle) and changing it does not change the throttling or value seen by Throttlestop.
    Searching the IFR output, I am unable to find a PP0 Current Limit or Package Current Limit.
    Do you have any idea, how I might be able to increase this limit?

    Thank you very much in advance.

    Can you post a screenshot of ThrottleStop with Limit Reasons open when your CPU is throttling? Use a consistent load like Cinebench or the TS Bench test.

    The current limit is in amps, the turbo power limits are in watts. You cannot convert one to the other by dividing by 4. Amps and watts are two different things. If ThrottleStop shows that the Lock bit is set, you will need a new bios that disables the lock bit. Once you boot up, if Lock is set, changes to the PP0 Current Limit are not possible.

    [​IMG]

    Are you using the FIVR - Disable and Lock Turbo Power Limits feature? This does not work on some Dell laptops because I think they are using the EC to force the turbo power limits. If you have this TS feature installed and enabled, and your throttling is power limit related (PL1 or PL2), ThrottleStop and XTU are not going to be able to fix your problem.

    Hi All,

    Looking for some advice, I used to use XTU, but since getting the Area 51m I have started using Throttlestop.

    I've had no issues until today, where I noticed that my CPU no longer reaches the 5ghz which I set in FIVR. HWInfo and CPU-Z show the multiplier as x49.

    Changes made:

    Speed Shift EPP = Enabled and set to 0
    BD Prochot = Unticked
    FIVR = All cores 1-8 set as x50
    CPU Core = -125mv
    CPU Cache = -125mv

    Throttlestop also runs on login as Task has been set. I haven't updated any drivers or made any changes 'knowingly' that may have caused reduced CPU turbo?

    Any advice on what I might have done to cause the CPU to not reach the x50 set?

    UPDATE: Installed XTU, removed Throttlestop task and .INI. Set similar parameters within XTU and the x50 multiplier is being recognised in HWINFO and CPU-Z. Its definitely something I've messed up in TS.

    @Fire Tiger - ThrottleStop used to have a limitation that on some computers, if you booted up at a 49 multiplier, you could not use ThrottleStop to overclock beyond that multiplier. Intel XTU does not have this limitation.

    It might be this problem or when you enabled Speed Shift, the maximum Speed Shift multiplier might still be sitting at 49. Open the TPL window and make sure Speed Shift Max is set to at least 50. You can also just max this out to 255 if you want to set and forget about it.

    For the first problem, try using the FIVR - Disable and Lock Turbo Power Limits feature. Within this feature is some code that tries to bypass the previous TS maximum multiplier limitation. If this does not work you will have to use XTU or boot up at the 50 multiplier.

    If I set the multiplier to x50 and reboot should this in theory resolve it, is that what the last comment refers to?

    Failing this working I'll go through the other options you suggested.

    Thanks for coming back to me as well, appreciate it.

    The multiplier you set in the bios and that you boot up at, might be the maximum multiplier that you can access when using ThrottleStop.

    This means that if you set a 49 multiplier in the bios, when you boot up into Windows, you might not be able to use ThrottleStop to overclock and access the 50 multiplier.

    Try the tricks I mentioned. When properly setup, this previous ThrottleStop limitation might not be a limitation anymore. The FIVR - Disable and Lock option should get rid of the maximum multiplier limitation so you can boot up at the 49 multiplier and use ThrottleStop to access the 50 multiplier and beyond.

    Thanks again for the response, its an Area 51m laptop I'm using.

    I haven't set any multipliers within the BIOS, not sure its even possible.

    The issue I have is that previously the x50 set within TS did show in HWInfo and CPU-Z, it was only at some point today its started to show as x49, in those apps despite the x50 setting in TS.

    I'll try those other steps and report back.

    If you did not go into the bios and enter a multiplier then it is whatever multiplier the bios has set your CPU to.

    If you are still having problems, post lots of pics of ThrottleStop. It is much easier to diagnose a problem if I can see how you have ThrottleStop setup and what TS is reporting when the CPU is loaded.

    All sorted thank you, I think for whatever reason the TPL had set to a range of 1-49. I changed the range to 1-50 and shutdown. Upon restart it's now showing x50 in HWInfo and CPU-Z. Thanks for taking the time to provide advice and get me sorted.

    Here you go - this is just after (within 5 seconds) the machine starting to throttle:
    upload_2019-9-25_19-58-6.png

    You got me there.
    I was hopeful that this single setting might be to blame and read that it is usually notated in 1/4 Ampere increments.
    My reasoning / hope was that ~ 18A and about 1V for the CPU would get me quite near to the 18W that I experience as the maximum long term power draw.

    That's a shame.
    This exact checkbox is checked the moment I cold boot my laptop and open an ini-free Throttlestop.

    I just gave this a try, but it results in the same throttling.
    So I guess this device is actually using the EC as an accomplice in its throttling endeavours.

    Thank you for your assistance and thank you so much for the great tool you provided us with!

    @FrozenLord - What are your turbo power limits set to in the TPL window? When testing, you need to check the FIVR - Disable and Lock box and you have to set your power limits appropriately high enough.

    ThrottleStop clearly shows PL1 in red. That is your long term turbo power limit which can be adjusted in the TPL window. Your current limit is not causing any problems. The 8250U has an Intel rated TDP of 15 watts so your laptop manufacturer has given you 18 watts. On the one hand, I guess you should not complain about their generosity but on the other hand, look at what an 8th Gen U is capable of when the power limits are completely disabled. I snapped the screenshot just a hair before thermal throttling kicked in.

    [​IMG]

    Let's just say that Lenovo is a lot more generous with their turbo power limits. The results are impressive for a supposed low power U series CPU.

    Is it possible to get the TDP level control to stick after restart? I understand Lock keeps it on until reboot but the TDP Level Control tick is also removed every time I restart.

    There is a forum here devoted to ThrottleStop. You may wish to post this message there.
    I do not know the answer, but UncleWebb will.

    Good luck,

    How can I find out in which processors the adjustment of the multiplication factor and voltage is available, in which overclocking through turbo boost is available in advance, to select the one to buy? Is there any table or list?

    Are you looking to buy a new laptop? The vast majority of laptops cannot be overclocked. Only the high dollar laptops with K series CPUs can be overclocked. For example, a mobile Core i9-9980HK has a K in its model name so you should be able to overclock it.

    You can use ThrottleStop to lower the maximum CPU multiplier (speed) but only the K series allow you to increase the multiplier higher than the default specs. Most recent Intel CPUs allow voltage adjustment using ThrottleStop or Intel XTU.

    Intel likes hiding their secrets. Finding a table that shows everything you would like to know is difficult to find. The Wiki Chip site has lots of interesting info. I also use CPU World and the Intel Ark site.

    https://en.wikichip.org/wiki/intel
    http://www.cpu-world.com/
    https://ark.intel.com/content/www/us/en/ark.html

    User reviews on Notebook Review are a good source of info. Do lots of reading and you should be able to learn what CPUs can do what and which laptops have some throttling issues.
    I never got around to finishing the TDP Level Control stuff in ThrottleStop due to lack of hardware and lack of user feedback. I do not own or have access to any low power U series CPUs for testing purposes. Virtually no one ever found any use for the ThrottleStop TDP Level Control feature.

    The problem is that TDP Level Control can be set in multiple locations within the CPU and ThrottleStop does not have access to all of them. Setting this in ThrottleStop can be overridden elsewhere within the CPU. What CPU and laptop do you have and what does the TDP Level Control setting do for you? Provide me with some more info and some examples and I will consider working on this feature some more.

    I'm more interested in the ability to manually adjust the multiplication factor and voltage to make an undervolt.
    I really like this on Core 2 DUO, Core 2 QUAD Desktop processors.
    In newer processors, these features are not common. Also I do not have information on mobile Core 2.
    I would like to buy a used laptop (replace the CPU in it) with the ability to fine-tune the processor using Multiplier & VID with Core 2 DUO or newer, and as I understand it, this feature depends on the processor and not on the laptop.

    Mentioned resources do not carry such information. This is known only to you, UncleWebb, and ThrottleStop users. Right?

    For Core 2 Duo CPUs that can be overclocked, look for an X in the processor name.

    X9000, X9100, QX9300, X7900, X7800

    https://ark.intel.com/content/www/us/en/ark/products/codename/26543/penryn.html

    https://ark.intel.com/content/www/us/en/ark/products/codename/2683/merom.html

    The Q stands for Quad which is a 4 core mobile CPU.

    The X7 series are unlocked mobile CPUs but they were on the hotter running 65nm process. The X9 series are 45nm so more room to overclock them without burning down the house or your lap.

    Just make sure that the laptop that you are interested in originally came with one of those processors. That way there is a much better chance that the latest bios supports it. Update the bios before swapping the CPU. If the bios version you are using does not support the CPU, it likely will get stuck trying to boot up. When this happens, you will not be able to go into the bios to see what is going on.

    As far as I know, the laptop chipset has to support overclocking.

    After that, you have to jump forward to Intel's 4th Gen Haswell CPUs. That was the return of under volting on the mobile CPUs.

    Thank you so much. Can you specify all Intel CPU families that support Undervolting? It would probably be nice to add this information to the header and Readme for all to see.

    How do I fix uneven core temps under load? One of my CPU cores is at a comparatively low 80 °C, another at ~87, and the rest are 94 and above. I don't have an IR thermometer with me—how do I know which cores are overheating, so I can sand down the hot plate appropriately?

    I'm also considering buying graphite thermal pads to replace the thermal paste I've used (Cooler Master Maker Gel Nano).

    I have another slight issue that I've noticed. When I boot my computer I can see HWInfo64 reporting max CPU frequency has hit x50. However, about 5-10 mins after my initial boot I can see the the CPU frequency never goes above x46. I can see the below IA Turbo limits being hit, is my UV too much at -125mV? Let me know if you need any more screenshots to help, thanks in advance.

    @Fire Tiger - Are you using the Windows High Performance power profile? On the main ThrottleStop screen you have Speed Shift EPP set to 0 for maximum performance. If you look in the FIVR window you posted in the table at the top right, it shows Speed Shift EPP is set to 84 within the CPU. This usually indicates that your Windows settings are in charge of your CPU. You might be on a Windows Balanced power profile. Check that and also check the TPL window for the Speed Shift Min and Max values. Windows might have changed one of those.

    If that does not solve your problem, try running the Dump program that Dufus wrote.

    https://drive.google.com/open?id=0B0dpSo9k93jDX1Fpa1FpTmo1Qk0

    It will create a log file which includes the status of your CPU. There might be something in there that has changed. Attach the log file to your next post or send a download link to me directly.

    If you are running any Dell specific software that controls your CPU, it might be overwriting what ThrottleStop is trying to do.

    The Windows profile is set to Balanced, should I have that as Maximum? I do have Alienware software but the CPU and GPU overclocking profiles have been disabled.

    I done a test and dropped the UV to -120mV and it seemed to stick at x50. Sorry for all the amateurish questions, just want to learn to do this right.

    Really appreciate the help

    Changed Microsoft Power Plan to Performance, left the TS UV to -120mV which allowed it to hit x50 in HWInfo.

    HWInfo no longer showing CPU going above x47 and IA Turbo Limits are being reached as per previous screenshots. After I dropped the UV last night to -120mV the IA Turbo was not being hit and HWInfo showed consistent x50.

    I've now ran and attached the dump you requested - https://drive.google.com/open?id=11UZ5D9YyS_zdJ73r-HzwJPEAF6ZJy-8V

    EDIT: OK, I double checked the UV, it had gone back to -125mV. I have again changed it to -120mV and IA Turbos are no longer being exceeded and its hitting x50.

    ThrottleStop is very consistent. When it makes changes, they usually stick. If your under volt is randomly changing, you must have some other software on your computer that is doing this. If you have another under volting related program on your computer running in the background and you do not think that it is active, well, you might be wrong.

    The register that controls that maximum CPU speed or the maximum turbo ratios is 0x1AD. In your Dump -120mV log file, it looks like this.
    Code:
    0x1AD 32323232:32323232
    The 32 is in hexadecimal which is equivalent to 50 in decimal. This register is set correctly. It shows that the CPU should use the 50 multiplier whether 1, 2, 3, 4, 5, 6, 7 or 8 cores are active.

    In your other log file, Dump.txt, take another look at register 0x1AD.
    Code:
    0x1AD 2E2E2E2F:2F303031
    Now this register, from right to left, is telling the CPU to use the following multipliers based on how many cores are active.

    1 core - 31 hex = 49
    2 cores - 30 hex = 48
    3 cores - 30 hex = 48
    4 cores - 2F hex = 47
    5 cores - 2F hex = 47
    6 cores - 2E hex = 46
    7 cores - 2E hex = 46
    8 cores - 2E hex = 46

    Unless you have made a mistake with ThrottleStop, there is some other software on your computer that is limiting your CPU's turbo multipliers. Is XTU still installed or some other Alien software? Best to only have one CPU control program running on ones computer. Take your pick.

    Do some more testing and keep a close eye on that register. If you are going to be using ThrottleStop, try to disable and delete whatever might be causing this. I would only be using a single ThrottleStop profile when testing. If you are using multiple profiles in ThrottleStop, make sure the Turbo Ratio Limits in the FIVR window are all set the same.

    The under volt is not causing this problem with the multiplier. That is just a coincidence.

    There is honestly nothing else active which is managing an OC or UV.

    What would the recommendation be in terms of MS Power Management, should that be Balanced or Performance?

    I'm not calling out TS by the way, its a great tool, I'm just new to it and looking for pointers in sorting this issue.

    Thanks for replying, I think my only option is to just change the UV up/down when it starts to become limited to x46 or x47 as this somehow seems to clear the limit and get all cores back at x50.

    If I make progress I'll let you know what I found.

    EDIT: Sorry for forgot to mention XTU has never been installed.

    How do you know that the Alienware software that you have installed is not messing with the Turbo Ratio Limits? The 0x1AD register is set by the bios when you boot up and after that, it should not change. It will only change if some program on your computer changes it.

    To troubleshoot, use ThrottleStop, set all of the Turbo Ratios to 50 and then exit ThrottleStop. Run the dump program. Have a look at the 0x1AD line and make sure it shows 32323232 for all of them. Next time you have a problem, do another Dump and check this register again. If it has changed, something on your computer has changed it. I have never heard of Windows changing it. If it has been changed, kill the Alienware software on your computer and test again. Kill anything else you can think of and test again. There has to be something.

    As I mentioned before, it is not the under volt. Opening the FIVR window and hitting OK likely sets the turbo ratio limits back to 50 across the board. You should not need to do this unless some other software on your computer is changing these limits without your knowledge.

    That is always good news but keep in mind that some overclocking software uses and installs some XTU components / libraries in the background. Open the Task Manager and have a look for anything XTU related.

    I prefer using the Windows High performance power profile. I use ThrottleStop to control my CPU. You can use ThrottleStop to enable and control Speed Shift if you want a slower CPU when lightly loaded.

    Yip you are correct and I am hanging my head in shame. I 100% knew the issue wasn't TS let me be clear on that I love TS since using it so thank you! I came here as I was hoping you'd have come across this type of issue, which it looks like you have....

    It definitely is the Alienware (AW) software thats causing the clocks to drop, this was based on my lack of knowledge on the program. If I boot and don't open the AW software clocks remain as set in TS. The minute I open AW software to change the fan profile, I can see HWInfo drop the clocks to x46 or x47 where they remain.

    In AW software there are fan, OC and light profiles, I had the OC section disabled thinking that means it won't mess with the clocks at all, when in actual fact it just means that when active it won't have an overclock, but it will still control the actual speeds in some variant. (Hope that makes sense, its being written while half asleep in excitement).

    So I now need to see if I can still run the AW software but uninstall the overclocking profile side, leaving only the fan and RGB controls.

    Thanks for all your help with this @unclewebb and keep up the good work!!!

    I almost forgot about the T7600G. After some ThrottleStop overclocking, it was way ahead of its time.

    I have seen a screenshot with ThrottleStop running on Ice Lake but there were some minor glitches like the BCLK and total MHz not being reported correctly. The FIVR stuff seemed to work OK.

    I have no plans on buying any new Intel hardware. Without access to new hardware, there will not be any new ThrottleStop versions. If I win the lottery, my plans might change. Further TS development for Intel's upcoming Lake series is not looking good at the moment.

    Good news. That is on my things to do list.
    Bad news. The list has not moved or progressed any during the last year.

    That is a feature that I would not want on my computer. Happy to hear that you were able to troubleshoot and solve your problem.

    I was the one that messed up, I disabled the OC profile which meant the CPU was set to run at default clocks.

    I have now turned off the CPU features all together allowing them to run in parallel without impacting each other.

    Thanks again!

    so if we can get you a zen 2 laptop isntead u'd develop TS for it? :D

    you could always do gofundme, i'd throw in a few. TS is at a point where its making me hard to choose AMD over intel.

    Is it possible to start Throttlestop with Windows with data turned off? I believe it might be causing some lag in conjuction with Razer Synapse ...

    @amihail91 - There is a ThrottleStop - Windows bug where some of ThrottleStop's settings are not getting saved. Windows 10 tries to shut down as fast as possible. That is a good thing but Windows is not notifying software like ThrottleStop that it is shutting down. The result is that ThrottleStop does not have time to save its settings.

    To work around this problem, try this. Turn data off and then exit ThrottleStop. Restart ThrottleStop and data should be off. Next time you reboot and start ThrottleStop, data should still be off. You have to manually exit ThrottleStop to make sure that this setting gets saved.

    ThrottleStop is very light on CPU resources so it is not likely the source of your lag issues but it never hurts to do some testing. You can also try adjusting the Options - AC Timer Res to a lower number. That might help.

    Every task on a Windows computer gets a fixed amount of time to complete the task. Windows has been using the default 15.625 ms time slice since the Windows 3.1 era and probably even before that. CPUs are much, much faster compared to then so maybe in 2019, the default time slice is too big. With modern CPUs cruising along at 4 billion cycles per second, 15.625 ms is like an eternity.

    The AC Timer Resolution lets a user adjust this setting. In the Options window, Timer Resolution (ms) shows the timer resolution that Windows is currently using. This value is only updated when you first open the Options window. Windows compares timer resolution requests from all programs running on your computer and then uses the lowest requested value.

    A ThrottleStop request of 16 should get you a Timer Resolution of 15.625 ms as long as some other software on your computer has not requested less.

    [​IMG]

    Google Chrome likes to adjust this value when you go to different sites. A lower value can be useful for sites that contain video. A lower value might smooth out some games.

    Just something to play with. Some games might already be setting this to a low value. In that situation, trying to change this in ThrottleStop will not have any effect because Windows always uses the lowest request.

    In your screenshot, AC Timer Res is set to 10 ms. That means ThrottleStop is requesting 10 ms. Some other software on your computer must be requesting 1 ms (0.997). It is typical for Google Chrome to do this. That is why some people complain that they get poor battery run time when using Chrome. A low Timer value will interrupt the CPU more often, keeping it awake, when the CPU should be idle in one of the deep C states, saving power.

    I agree. :)

    Hi, I have a 8th gen cpu (i7-850h) in a msi gp63 8RE. First, english is not my first language, so I apologize in avance if I make grammar mistakes.

    Second, in spanish there aren't so many guides to follow and some of them are wrong when I compare the steps with the english guides. So, I look info just in english.

    I have done all the steps (the basics, like notebookreview guide), but I keep having thermal issues when I run tsbench, the cinebench and the aida test. But, in cinebench I have a record of 2700 cb points.

    I don't know what else to do, I want to reduce the thermal and keep a good performance. I will apreciate your help.

    I share my captures:

    And I also have an error when I run the 1024m testbench:

    [​IMG]

    Should I increase o decrease the undervolt to avoid this problem?

    I share my log: https://pastebin.com/raw/Qz7naJaT

    Thanks in avance.

    If you are having error during ts bench than you need to lower your voltage for core and cache.
    Try for example -120 instead of -135 and than check ts bench. if ok than make -121 if still ok go for - 122 and so on.
    As for your UV for iGPU than probably it is not working, you need set both intel igpu and igpu unslice equal like core and cache, for example both -60.
    As you are having msi laptop I need to ask if you have done AC DC loadline calibration explained by @Falkentyne. Probably not.
    You need move to bios and set AC DC loadline calibration to 1 under vr core ia domain. you can also set ther current for 928 which should help with throttle.
    I alson find that setting ac dc LL calibration for other domains like igpu and system agent also helps a bit. You need to remember to reset your UV in ts because you wont be able to uv by that amount aftet that. probably not more than -50 for all but all in all you will have bettet temps after that.

    Another thing is from what I can see is that you have some huge disproportion betwean hottest and coldest cpu core which can mean that you need to reaply thermal paste or in worse scenario you can have uneven contact betwean your heatsink and cpu die and you might need to work on that.

    If you are not afraid and first check for uneven haetsink you may use liquid metal which will massivly help with your temps. we got here nice thread about application of LM and foam barriers which you can read.

    If not brave enough to use LM than try some high end thermal paste like Phobya Nanogrease Extreme 16W/mK or TG Kryonaut 12.5W/mK

    And by the way set all iccmax to highest values

    On msi lap you can also try to OC your mem. From my personal observations I can say that the faster the ram is, the lower the power consumption of cpu is. But if someone could confirm that. personaly moving from 2666mhz to 3193 mhz made reduce of arround 1 - 2 W during ts bench. My explain for that is thatbthe cpu can faster finish tasks so it can be a bit cooler

    it can.. I flashed a new BIOS with security fixes for my Dell G7 and they seemed to have blocked access to the EC (even in linux I can't dump the registers anymore). When i have "disable and lock turbo power limits" enabled in TS, my laptop locks up for 4-5 seconds randomly. If I open RWEverything and click "EC" my laptop stops charging, keyboard light flashes, it locks up and hard drives become read only it seems as windows acts like you unplugged it's main boot drive and after 5 minutes the nvidia driver crashes. It's a repeatable process. It's super strange and super sad.

    Off Topic: the dell power manager seems to communicate with the EC. When you set it to "quiet" it can throttle the CPU and not set any flags in throttle stop. Just like it does when it throttles to 45 watts at 80 seconds on ultra performance mode. Trying to figure out how it communicates but no go yet. I tried modifying UEFI registers for slope and offset but the EC must have the final say regardless because it doesn't work like it did on my HP X360 with the 8550u

    Thanks for your reply.

    First, I follow your instructions and the limit was -131.8 on cache and core, but I still have thermal issues. About the iccmax values, should I increase to the highest values on both (cache and core)?

    Second, I set the same value on igpu and unslice. What about in system agent?

    Third, I haven´t done the acdc loadline calibration. I've been reading about that, but I still don't know how to unlock the bios.

    Fourth, the thermal paste and the heatsink problem it's a really bad new. I have never reaply a thermal paste and I know that open this laptop it's kind a difficult.

    Finally, I will look for info about overclocking my mem.

    Thank you, I will send more captures and data when I have made the changes.

    Anyone else noticing slighlty better performance and temps with SpeedShift disabled letting Windows 10 handle it with EPP?

    That statement does not make sense. If Speed Shift is disabled, Windows 10 cannot use EPP to control the CPU.

    Post some ThrottleStop pics showing the comparison you did. To disable Speed Shift, you need to reboot so the CPU can reset itself. On many recent computers, Speed Shift is automatically enabled by the bios or by Windows 10 and there is no easy way to disable it.

    I've found ThrottleStop is the only program that can affect my Gemini Lake Pentium N5000 on my Acer Spin 1, though only in a limited way. I can reduce the boost speed of each core count, which frees up power for GPU performance, but no power and Turbo time settings seem to have any effect on the 7w throttle limit or how soon it takes effect, regardless of temperature...

    Share some screenshots of how you have TS set up with your computer. :)

    Only then can someone make a solid suggestion for you. ;)

    I can't find how to post screenshots... I'm not sure if I've unlocked that ability on this forum or if I just can't find it... argh! "Uploads are not available" is what I see when I try to drag my screenshot files onto the post I'm writing.
