The ThrottleStop Guide

I just used XTU to show the chart of the erratical behavior. I have the same results with Throttlestop alone.

Also on the second screenshot I have XTU running alone without anything running on the background after a cold startup.

Thanks

 

then most probably this is due to short/long turbo time limit.... check these settings. there are no other reasons observable from the pics you've posted

 

1 - You appear to be thermal throttling. 95c should be the throttle point for that chip, and you definitely hit 95c max on core #2 according to throttlestop.
2 - XTU has more throttle reasons. "TDP throttle" is one, as is "Current Limit throttle", and finally "Thermal throttle".
3 - Limit Reasons built into TS8 beta 2 also works to show what the throttle reasons are.
4 - From your screenshot I cannot tell, but your chip doesn't appear to be running beyond the TDP limit (and TDP throttle is not lit up) at the time, so I don't think it was TDP throttling.

 

short/long turbo time as reported on XTU and ThrottleStop. I have changed these settings in the NVRAM using the UEFI variables. Default settings were 45W and +12,5% 56,250W respectively.



EDIT: readjusted to 100W/128W just in case. No difference...

Spoiler

1 - I can definetely say that this is not thermal throttling since with closed bottom lid, I have seen this chip going all the way up to 105 and then thermal throttling kicked in. ( I can reproduce if interested).I will test further though to see if there is something else that throttles the machine because of high temperatures...


i7-3740QM @ 3.8GHz 1024M TS Bench screenshot from XTU
(Throttling shown in the end of the full load graph) This was @ 104C on core 2 if memory serves.

2 - ?

3/4 - I could see that this was a TDP Throttle before changing the long/short power limits in NVRAM. WIth prime 95 full load (55.6W load on CPU) + Furmark, The TDP Throttle circle was becoming black and GPU would throttle @ 650MHz and my CPU would have the same behaviour after some time...
With the new NVRAM settings this is what I get



after a little while TDP Throttle...

~56W Full Load Package power CPU only

 

My sensor tab looks like this: http://puu.sh/jH1oM/3df7e283cb.png

I've poked around a bit and I don't see anything that shows me code when I mouse over it

 

Intere

sting...

it should say "perfcap reason" near the bottom. Hmm... not sure what to tell you then.

 

The ThrottleStop screenshots you posted while testing with Furmark and Prime95 are all showing the full 38.00 multiplier. Can you post a screenshot of ThrottleStop while this throttling is happening?

Edit - I went back to your first post and saw the ThrottleStop screenshot at 26X. Your screenshots just above this post had Set Multiplier checked and BD PROCHOT was not checked so I just wanted to confirm if these 2 items made any difference.

The 3rd Gen CPUs are good until 105°C and ThrottleStop is not showing a check mark in the PROCHOT box so it is definitely not thermal throttling.

Unfortunately the Limit Reasons program that Dufus wrote only works on the 4th Gen and newer CPUs. This additional throttling information does not exist in the 3rd Gen CPUs so Limit Reasons cannot read this info from your CPU.

The Intel datasheet shows that the 3rd Gen 45 Watt mobile processors have a maximum short term limit of 72 Watts, a maximum long term limit of 60 watts and the maximum turbo time limit is 64 seconds.

I know you have reprogrammed the power limits in the NVRAM but I have not ever done any testing of this. I don't know how a processor reacts when you go beyond the datasheet limits. In this case, the datasheet limits might be completely meaningless. You could try lowering the time limit to 64 seconds to see if that makes any difference.

Is your power adapter near its limit or is it maybe overheating? The square wave in the XTU graph on the previous page was almost too perfect. When the CPU is the cause of the throttling, the MHz tend to vary randomly.

 

Alright, if I find a way to get PerfCap to appear I'll report back, unless there is other software that would be able to get the needed information. Thanks for all your help so far!

 

Set multiplier feature seems like it stops the huge waiting @×26 while it will bring the spiking ×38 - ×26 you can see on the first image.
BDPROCHOT was suggested by Khenglish and other users as it may be the problem. The truth is that I didn't see any difference.

I can verify that, since I tested by setting the TCC Activation offset at 15 in the NVRAM... The result was PROCHOT signal @ 90C and ThrottleStop showing a checkmark there...

I knew about the 60W/72W mark but I don't think it is true since with an invalid adapter I could draw the full +76W TDP till I was temperature throttled...
But in torture tests it mostly won't go over 58W even under huge load for CPU alone.

Tested with two Dell original adapters 130W and 90W both of them recognised with the right wattage in Bios. None of them showed any sign of overheating..

Speaking of which after a bios update gone rogue my E6430's motherboard is now bricked .. Hope I will find a cheap replacement..

The answer lies in there

 

@Dufus @unclewebb Sorry guys Dell called this morning to inform me that an earlier pick up was scheduled and if I was available. No excuse came to mind other than "I'm not done experimenting with the CPU" so I told them no problem^^'.

So I don't have the Alienware anymore and can't do more testing with the 4980HQ. Wish I could've given you more accurate data.

I'm back to my loyal 3610QM. I've had it for 3 years so I was thinking of doing a repasting of the CPU and GPU, what do you guys use ?

 

That's ok, we can find more AW owners. There's a whole thread of them floating around, and they eventually end up here when their CPUs stick at 2.8GHz even though they paid through the nose for them XD.

 

Your testing feedback was appreciated, wish there were more posters like yourself. Usually when trying to help there is little or no feedback or sadly in some cases, negative comments.

3610QM is still a good processor, maybe try some IC7 Diamond or if you want to go a bit further CLU.

I'll be going away for a while so until we meet again thanks for taking the time to post your results.

 

Hi guys, I've just signed up to the site just to thank you for all this info that helped me to come back to life Turbo Boost again.
I've got an HP laptop with 2720QM and suddenly few months back turbo stopped working, getting stuck to a max of 22x multiplier. I have formatted and reinstalled Win8.1 Pro, also tried with Win7 SP1, went back to my old HDD since I've changed it by an SSD and nothing worked. Although I "fixed" my problem using Throttle Stop by loading it on Win startup, I still have in my mind the curiosity of how is it possible that all of the sudden turbo stops working on Windows, but on Live Linux OSes it works?
Probably some of you have got the knowledge/experience to know the possible answer.

Thank you very much to all.

PS: As I'm new here I'm sorry if I should have posted first in some welcome thread or something. Please let me know.
PS2: Sorry for my bad english.

 

It's possible you had some HP software that updated itself... I don't know if you reinstalled the HP software when you redid windows each time. If you didn't, then I have absolutely no idea, will proceed to assume your notebook is possessed, and suggest you sell it and buy a clevo XD.

 

LOL yeah I also suppose it is some kind of possessed... but no, I haven't reinstalled any of that on each formatting I made so ... no clue :S
All testing made was with Windows from scratch with no drivers or additional software or windows updates, nothing at all.

 

No drivers at all? No video, chipset, etc.?

I'd be surprised if everything was working as intended with literally zero drivers after a windows install...


Sent from my iPhone using Tapatalk

 

No drivers added apart from those windows have installed for you. There is no need for an additional driver to have turbo boost working.

Over the last 2 years I have reinstalled win8 and 8.1 several times and as I said with no additional drivers, probably only for hot keys on keyboard, and turbo was working always fine until few months ago.

 

Now i made my settings in FIVR and i have some questions

1- Do i have to open throttlestop every time i boot to apply the settings or they are automatically applied even without opening the utility?

2- what does "set multiplier" do?

Thank you for this awesome app

 

From my personal and very short experience with the utility:
1 - Yes you have to, at least I couldn't find any permanent setting. So I added the utility to Windows Task Scheduler to be run when boot up.
2 - Answer is on first post.

 

1- I never knew that there is a Task Scheduler in windows .. added throttlestop to work on boot. Thanks!
2- I read the first post but i can't understand what's the difference between it and this

i think i can use it to make my clocks more stable? idk

 

ThrottleStop is a multi purpose tool that supports as many Intel CPUs as possible that were produced during the last 9 years. For the older Core 2 Duo, Set Multiplier was the one and only way to control the CPU speed. With the 4th Gen Core i CPUs, you can still use Set Multiplier but you can also use the FIVR - Turbo Ratio Limits if you are only interested in controlling the turbo ratios. To go lower than the default multiplier, you will need to use Set Multiplier.

For the 1st Gen non-Extreme Core i CPUs, software does not give you much control over the turbo multipliers. I have never owned one but I think you get either full turbo boost or no turbo boost with nothing in between. Some of the newer low power UM CPUs also have limited control over their speed. When the UM enters one of the low power TDP Levels, the maximum multiplier will be fixed.

Use whatever ThrottleStop features that allow you to best control your CPU. If you are trying to control your CPU and you are not sure how to do it with ThrottleStop or if it is possible, just ask.

Where have you been? The Task Scheduler was released 9 years ago when Windows Vista was released. If Microsoft was smart, they would have made this the one and only way for applications to start up with Windows. The second post in this ThrottleStop thread has some info about using the Task Scheduler. Unfortunately, all of the informative images were originally hosted on imageshack. I didn't want to give imageshack any cash so they replaced my images with ads for Apple iTunes crap. Thanks.

ThrottleStop has zero interaction with your bios. That means every time you boot up, you will need to run ThrottleStop. I think this is a good safety feature. If you ever enter and save some unsafe settings into ThrottleStop, you should always be able to boot up into safe mode, delete the ThrottleStop.INI configuration file and then reboot and start again. You shouldn't be using the Task Scheduler until you have found some safe settings but most users ignore that good advice so at least there is a way to recover in case you do something bad.

 

Ok i have another question, my cpu is i7 4712hq. it's 37W TDP

i used throttlestop and tweaked my cpu with these settings , 2

now my cpu is stable at 3.2 GHz and is trying to increase more than 3.2GHz .. it can reach 3.5 GHz but always decrease to 3.2 GHz

do you recommend me to set multiplier to 32 or just leave it? and any other recommended settings?

thank you very much for this awesome app. it's 10000 times better than xtu for me

 

I think this is an interesting article on throttling with intel's ME 8.1. It gives some clues to their thinking with management of passively-cooled devices.

http://www.anandtech.com/show/9550/...ower-and-thermal-framework-smarter-throttling

 

Thank you. Happy users keeps me going on this project. I like XTU but I prefer less bloat and the simple approach of ThrottleStop.

The FIVR - Turbo Ratio Limits shows the maximum limits for your CPU. 3.2 GHz is the maximum speed when 3 or 4 cores are active. When lightly loaded and only 2 cores are active, your CPU can increase to 3.4 GHz and when only a single core is active, your CPU can turbo boost up to 3.5 GHz. It is normal for these CPUs to constantly adjust their speed based mostly on how many cores are active. Less background tasks running on your computer allows your CPU to run faster. Turning off XTU and other monitoring apps like CPU-Z reduces the load on the CPU and that allows more turbo boost. I am a bit OCD about keeping ThrottleStop lean as well as getting rid of unnecessary background tasks. With ThrottleStop in Monitoring mode, it is possible to see C0% load numbers as low as 0.2%.

http://i.imgur.com/RMShAdQ.png

The Lenovo Y510P uses the Set Multiplier register for throttling purposes. This can drop my 4700MQ down to 2.4 GHz so I need to use the Set Multiplier feature to prevent this from happening. Try running a single threaded benchmark like 1 thread of the TS Bench or something simple like Super Pi Mod and watch what multiplier is reported. It should be close to 3.5 GHz but not quite because Windows always needs to wake up additional cores to process background tasks while your benchmark is running. Background processing is what prevents the CPU from continuously using the 35 multiplier. For your laptop, checking Set Multiplier might not make any difference but I usually set it to the maximum value (35 T - 4712HQ) and I check this option just to make sure.

I also like overclocking the cache ratio as well as setting the Min and Max cache ratio to the maximum value. Will this make any real world difference? Probably not but I always like any performance boost that is free. Reducing the Intel GPU voltage might also help a little. Adding VCCIN reporting and adjustment to ThrottleStop is on the immediate things to do list.

Are there any options in the TPL window that are not locked? I think most of the good stuff is probably locked on the 4712HQ.

@Eason - Thanks for posting that info. I think some people have been able to uninstall the DPTF driver to prevent some of these modern throttling schemes.

 

Actually in FIVR i can increase the multipliers to 35 on 4 cores Photo but i am not sure if that's safe? because in XTU it's +2 multipliers only so it should be 35 / 34 / 30 / 30

I increased all cores to 35 / set multiplier at 35 and i am getting more stable frequency at 3.4 GHz Photo
1 thread ts bench resulted in 3.4GHz! gooood Photo

About increasing cache ratio isn't that should decrease the frequency? and i can't understand the VCCIN reporting and adjustment actually where can i find it?
here is TPL Photo
And what does C1E do? "i read the first post and still can't get it"

and in limit reasons EDP is flashing i think it's about current right?

you sir are my hero.

 

CPU World shows that the default multipliers for your CPU are 33, 32, 30, 30.

http://www.cpu-world.com/CPUs/Core_i7/Intel-Core i7-4712HQ Mobile processor.html

Intel allows +2 bins of overclocking so the maximum multipliers when overclocking are 35, 34, 32, 32. Intel XTU should allow you to set your CPU to those multipliers. ThrottleStop lets you adjust this to 35, 35, 35, 35 but on a 4712HQ, those settings will be ignored so your CPU will use the 35, 34, 32, 32 values instead. When I was adding this feature, I wasn't 100% sure how to read the default values from the CPU so I just left this unlocked just in case some CPU that Intel forgot to lock might be able to benefit from this adjustment.

The 1 thread TS Bench test is a good way to measure how many apps are running in the background on your system. Here's the theory. The TS Bench test is going to keep one core of your CPU active. If Windows has some background processing that needs to be done, that is usually going to be scheduled on one of the inactive cores. When a second, third or fourth core becomes active, the multiplier immediately drops. Cores are constantly entering and exiting various C States so the multiplier is constantly adjusting. If Windows does not have a lot of background crap that needs to be processed, these additional cores can remain inactive so your CPU can stay running at the maximum possible speed.

Your maximum multiplier is 35 and your screenshot during this test shows a multiplier of 34.66. You are right, that is good but.......

This is better.



The 4700MQ has a maximum multiplier of 36.00. A reported multiplier of 35.98 is a good sign that my laptop running Windows 10 is very lean. Not a lot of crap running in the background so the CPU is not waking up additional cores very often which lets the CPU run as fast as possible. Will I ever see a number like that if XTU is running in the background? Not a chance. XTU is too inefficient.

When C1E was first introduced, it significantly reduced idle power consumption but these days, idle cores have much better options available. A 4th Gen mobile CPU core will quickly drop down and spend most of its time in the low power C7 state which means the core no longer spends any significant amount of time in C1E. Intel continues to recommend that C1E should always be enabled but I don't think it is that important anymore.

When you see EDP turning red in Limit Reasons, that is a sign that your CPU is throttling because it is hitting the current limit. Your TPL screenshot shows that this is set to 53 amps and best of all, this register is not locked. Try increasing this value and watch to see if EDP goes away. By default, Lenovo set my 4700MQ to 85 amps. CPUs can be throttled by a multitude of different registers. If something is left unlocked, it is always worth giving it a boost to see what happens.

A higher cache ratio means the CPU can read and write information to the cache quicker. As long as your CPU remains stable, the higher the better.

I said, VCCIN reporting is on the things to do list. That's why you cannot see this adjustment yet in your version of ThrottleStop.

 

That's why i hate XTU

I increased it to 54 .. i will see if it will flash again, but i made a ts bench and i think that's good for the number of apps running?

Edit: i increased it to 70, wouldn't that harm the laptop or anything?



not stable at 34.88 but it's changing from 34.3 to 34.88. maybe not so good compared to 4700MQ but definitely better than stock

the cpu is 37W which is making everything worse than a 47W CPU, i thought it's 47W when i bought my laptop but this bad boy made me learn a lot of new stuff

ahh sorry my bad

 

Come on man, live a little.

Increasing this from 53 to 54 is not going to nuke your laptop. I think the previous 3rd Generation mobile CPUs were set far higher than this. If EDP is flashing red, your CPU is being throttled and increasing the Current Limit might help prevent that. My Y510P is locked to 85 amps and it has not caught on fire yet. I never see EDP flashing red because Lenovo did one thing right, they set the current limit appropriately.

37W CPUs are not going to be as fast as a 47W CPU when fully loaded but for most apps, 37W is fine. At least you didn't end up with a low powered U or Atom CPU. The Best Buy flyer beside me is full of these things with no mention of what their limitations are. Buyer beware.

 

@unclewebb can confirm, default 112A on my 3630QM:

 

Thanks @octiceps.

I started digging through the ThrottleStop Forum archives and found this screenshot.

http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/page-141#post-8946623

The 35 watt Core i7-3520M also had a Package Current Limit of 112 amps. Too bad fear and throttling have gripped the 4th Gen line up.

 

so why intel or HP set the cpu at 53A?

isn't higher current means higher battery usage, higher temps, and hitting the power limit faster?

sorry guys a noob here

 

Manufacturers throttle their laptops for a variety of reasons. The purpose of ThrottleStop is to give users more control of these design decisions. If HP left the Current Limit register unlocked, I assume the engineers at HP are comfortable with advanced users increasing this value. Maybe it is like an Easter egg or special bonus feature. If HP thought increasing the Current Limit was going to cause problems, they would set a single bit in the bios which would lock this register and prevent you from changing it.

When fully loaded, a faster CPU will consume more power and will also create more heat. When using ThrottleStop, the choice is yours. If you are plugged in and if you are interested in maximizing full load performance then I would increase the current limit. If you are running on battery power and want your CPU to limp along like a Netbook, you can use ThrottleStop to do that too.

 

HP engineers unlocked the current editing and made the fan only works at full speed after Temps hit 90C

And when the Temps hit 90C cpu throttles to 2.3 Ghz.. Thank you HP lol

...

Thank you very much unclewebb for helping me

Just a couple of days ago I had a good chuckle on how apparently a Z87 + i7-4770K system had both Package Power Limits set to 4095 (by default), and even after seeing many users of both Sandy and Ivy Bridge CPUs having noticeably higher limits than default (3-6x higher), while I'm also running higher limits with no issues whatsoever. For desktop users, the real main concern goes through being able to provide sufficient cooling to maintain required performance from user-specified clock rates.

All in all, ThrottleStop keep pushing onwards on basically all systems I've tried, ranging from Atom to i7/Xeon counterpart systems, with ease.

On the Windows 10 subject being discussed a few pages back, I personally recognize that Windows 10 is technically better but I simply will not willingly sacrifice control over my system, be it through lack of system updating management or any of the multitude of privacy intrusion issues that come by default on that OS, meaning I'll remain on Windows 8.1 for the foreseeable future. And yes, it should be said that Microsoft has released several updates for both Windows 7 and 8.x that change reporting permissions outside what's easily accessible through system settings. Here is an incomplete list of updates that I would suggest any Windows 7/8.x user to uninstall and block from future update requests:
- KB2505438
- KB2952664
- KB3021917
- KB3035583 (no more Windows 10 update offer nag tray icon)
- KB3075249

 

Hey @unclewebb, I can't seem to start a private message convo with you, so I'm posting here:

So I was testing the effect of the CPU bottleneck on Dying Light. Turns out that by some luck of the draw, I managed to force Windows to give me more CPU power. I got the screenshots in order. I started at 3.5GHz and then went down to 2.7GHz, then went to 3.8GHz (had a boost in utilize-able CPU power here), then to 3GHz (lost the boost), then to 3.3GHz (got a better boost here) and then my FPS permanently kept that boost, even though it now scaled to that higher number.

Here's the album in question; I actually signed into imgur to keep track of it:
http://imgur.com/a/FkTD7

Also, for some reason, throttlestop's set multiplier button no longer works and my CPU won't go below 2.7GHz for any reason, even at idle, or on battery, so that's why you didn't see me ticking the "set multiplier" button; but rather I adjusted the FIVR turbo limits each time.

 

@D2 Ultima - About 10 pages ago in this thread, Dufus reminded me of a register that can override the Set Multiplier register.

http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/page-337

I have added control of this register back into ThrottleStop but I need to do a few more things before I release the next beta. On my 4700MQ, I can use the Set Multiplier feature and select any multi between 8 and 34 and have the CPU run at that speed. Put a mild load on your CPU like a single thread of the TS Bench. If you cannot run at every multiplier using the Set Multiplier feature, it is very likely that this other register is being used on your laptop.

I had a look at your testing but I am not sure if it proves anything. When the multiplier goes up, the reported Windows CPU % Utilization also goes up. When the multiplier goes down, the reported Windows CPU % Utilization goes down. I think changing Set Multiplier or in your case the Turbo Ratios is only showing this during your testing.

Question - Is a setting of 256A for current some sort of magic number. I think Dufus told me about this a while ago but my laptop is still all locked up so I have not tested this register.

 

Yeah, I think set multiplier never really worked for me (except to stop me falling under max non-turbo boost). I never had an issue, because I never had performance problems, but it makes testing hard now XD. Mild loads can't trick the multiplier for me. For whatever reason, I *NEVER* go under 2.7GHz right now, even at 100% idle on battery with 50% max CPU speed in windows power plan.

As for my testing, it's how my FPS suddenly spiked by about 10fps with me standing in the same spot when I somehow managed to trick the game? windows? something? into giving me another ~8% of power. Same 3.5GHz as the first picture, but CPU load was higher and FPS was better. I lowered GPU settings so I could force a CPU bottleneck there (normally I'm at a CPU bottleneck anyway, but I wanted it to be more pronounced, as the GPU load was in the high 80s to low 90s). The problem now is that I don't understand why CPU util seemingly went down when I removed turbo boost, but my FPS had barely changed. It was hovering between 104-106, and dropping from 3.5GHz to 2.7GHz on a CPU bottleneck gave me 102-104fps? That's nothing. But then I raised the clocks, went back down, then re-arrived at my default 3.5GHz with suddenly a solid +10fps boost for basically doing absolutely nothing. I don't understand it at all.

In the past too, I've OC'd my CPU on the fly while in Dying Light, and it has done an exceedingly negligible FPS boost too, but today was pretty different there. Imagine if I had a 4930MX and could have set the CPU to 4.3GHz instead of just over 3.8GHz?

As for 256A, it seems to be a magical number. It stops XTU benchmark from throttling and it stops Linpack from throttling too. 100A, 120A, 150A, all meant nothing to those tests. 256A was needed so I left 256A on 24/7 from now on. I'm really glad for throttlestop because my BIOS keeps forgetting what my current limit is set to (ever since I got the machine). Almost every time I restart it's back to 72A (the default). But obviously I can raise it via programs like XTU and Throttlestop.

 

Hi,

I've downloaded the latest version from the link in the first post, but the app doesn't seem to open at all - currently using Windows 10 x64.

I have tried running as Administrator etc. but the program just doesn't open at all. Desperate to use the BD PROCHOT on my Alienware 17 R2 to reduce CPU throttling.

Any ideas?

 

Any tips for dealing with 4790K @unclewebb ? Have no idea about undervolting/overclocking in Haswell... Others are also welcome to chime in...

 

Other people have reported problems running ThrottleStop in Windows 10 x64 but they never let me know if they ever found a solution to their problem.

I have been using ThrottleStop 8.00 since Windows 10 x64 was released and I have not had a single problem. I am using Avast but I have disabled a lot of the excessive nanny features in that program. What antivirus program are you using? I am assuming you are trying to use ThrottleStop 8.00 beta 2 and you downloaded it from the same location as my signature shows. I am also assuming that you read the included ReadMe file that I included in the download.

When you try to run ThrottleStop, does it show up in the Task Manager? Where do you have the ThrottleStop folder located on your hard drive? Did you remember to unzip all of the files into a folder? I created a folder here,

C:\Program Files (x86)\ThrottleStop

If you ever get ThrottleStop to start, can you do others a favor and tell us what your secret was.

@TomJGX - The 4790K is used mostly as a desktop processor and most users seem to do all of their overclocking and voltage adjustments in the bios. It should be possible to use ThrottleStop on a 4790K as long as the bios has not locked anything important. Have you looked in the ThrottleStop - FIVR window? In theory, you should be able to click on Overclock and raise your multipliers and then check Unlock Adjustable Voltage and you can have fun playing with that. If you are not sure about something just post a very specific question.

@D2 Ultima - Don't delete your pictures. I need to have a second look when I have some more time.

 

Oh they're going to stay; that's why I made the album while signed in on Imgur. Also, they're on my PC. I plan to do a little more testing in the future.

 

@AhmedouviX Intel spec for 37W is 55A. Current is based on VCCIN for FIVR chips while older chips such as Ivybridge are based on Vcore. For 100W at a typically VCCIN of 1.8V would draw about 56A while 100W for Ivybridge at Vcore 1.1V would draw 91A for the same 100W. Ironically since Intel power estimations are based on VCCIN current then reducing VCCIN will result in power estimations being higher due to higher current.
For instance same load, clocks and tempperature VCCIN 1.900V 27.2W, VCCIN 1.400V 32.4W
.
For fan control check if you have HP cool and quiet running. Failing that there might be the option of changing fan tables in the EC which can be read with RWEverything.

@unclewebb I also use 256A limit due to EDP throttling above 3.6GHz. See https://communities.intel.com/docs/DOC-23517

 

Thurkar, it's a matter of TDP limit of 47w. Which is the same as my 5950HQ, and it will hold 35x indefinitely. At 36x it will drop to 35x, and back up 36x, averaging 35.6x for long runs. Averaging out TDP around 46.8w. I have run it for hours this way.

I wouldn't worry about it, unless you really need sustained CPU over 36x for long batch jobs, maybe a laptop isn't the best place to do that computation, do it remotely via the laptop to a compute server somewhere.

The overall gaming performance should be awesome enough

 

I fixed that for you so he can get chips like these that won't throttle.

 

Hello ! I actually sent mine back for refund but I am sure this info will be useful for others Aw17 owners facing the same issue, so thanks for the feedback !

Options are always nice to have too .

I actually postponed my purchase of a laptop and am waiting on parts to build my desktop, I bought the i7 4790K with the Gtx 970, and kept my 3 year old laptop for mobility.

 

my CPU is 4712hq 37W. sometimes when i put my system underload with geekbench for example the package power exceeds 37W. it can achieve 40-44W

How is that possible?

 

How long does it stay there? Your short turbo power boost is 47W, and should last about 2.5 minutes. If you manage 5 minutes or more, and you confirm with throttlestop that your turbo power limit is 37W, then you might have one of those rare HQ chips that can surpass its power limits (read the HQ section in my i7 guide for more info).

 

not even a single minute lol

i wonder why it's not possible to pass tdp limits when it's possible for 2.5 minutes

 

Because Intel decided laptop users don't need CPU power for anything, and since games use very little CPU power compared to say... rendering programs or benchmark programs, this happened.
