The ThrottleStop Guide

can any1 teach me how to teaw core i7 2720 with this amazing soft by image,cause my english reading skill is not so good,so i can hardly understand the #1 post

 

Any Eta on when throttlestop will support Ivy Bridge? 4.1 Doesn't seem to be working well with mobile Ivy Bridge sadly..

 

ThrottleStop is free but unfortunately new hardware for development purposes is not.

It is going to be many months before I buy an Ivy Bridge CPU and my available time for this project has become very limited. If there is a problem with ThrottleStop then post some screen shots so I can have a look at how you have ThrottleStop set up. From that I might be able to figure something out. Do any ThrottleStop features work?

Ivy Bridge is not significantly different from the previous Sandy Bridge CPUs so the problems you are having might be solvable with a minor tweak or two.

 

hey i just wanted to know if it is possible to use throttlestop only as a temp monitoring software as long as i dont remove the tick next to BD PROCHOT. my PSU and right side of my g73 gets quite hot when i use throttling disabled all the time. so i only want it when i need it.

i have the tick next to BD Prochot and set TS to monitor only, this would mean im not manipulating default throttling right? just to confirm.

 

Hello guys i have G73SW-A1 with a 2960XM(SR02F) its not a ES cpu. my turbo doesn't seem to come on at all. The max it will run is up to 27 Multiplier. Does anyone know how i can make the turbo run?

 

Yeah. I'm not real familiar with Throttlestop to begin with, but perhaps if someone could explain how to do this with Sandy Bridge it may work with Ivy Bridge.

Two things, somehow I was able to get my CPU (i7-3610QM) to run at 800MHz once. Now I can't recreate it. It's default lowest speed is 1200MHz (Multi 12x @ 100MHz FSB)

Secondly, lock in Turbo state. I read in documentation to set multi to 12x + 1 or 13x. But that didn't work. Setting to Turbo doesn't do anything either. Only thing that ends up happening when I mess with Throttlestop is it seems to lock the system in the state that it was at when I turn it on and requires a reboot to get it back to "normal".

unclewebb - thanks for your dedication to this project though. Look forward to your input when you finally get a chance to tune your program for Ivy Bridge.

 

This is exactly what I was referring to when I said that throttlestop doesn't support Ivy Bridge. None of the settings stick or do anything, besides lowering the 3610qm's clock from 1200mhz to 800mhz, which needs a reboot to get back to normal.

 

A multi of 8 is kinda cool though. As HT pointed out a multi below 12 isn't even officially supported...

 

Hello, congrats for your app unclewebb..
I'm having problems using this app on my MacBook Pro 13 2011 i7 2260m under bootcamp. I've install windows just for playing some games but my cpu keeps throttling and throttling.. I already did a new installation but with no luck.. already changed my power plans and used this app but the cpu keeps throttling..

What can i do? Im starting to get pissed off..

 

I have a Core 2 Duo P8700. The multiplier is set at 10 and I checked the box. When I run a test the FID displayed stays at 9.5 and never gets to 10.

Am I missing something in my settings that would not allow the FID to reach 10?

 

the bios needs to have the EIST-lock bit unset. See the dualIDA bios link in my sig for a list of modded bios and info on how you could modify yours to then allow dualIDA mode to work.

 

nunocaires: Your MacBook Pro has a completely inadequate cooling solution. That's why it throttles. There is nothing that ThrottleStop can do to fix a bad design. Apple thinks it is OK to sell products that run hot as hell and they consider a CPU throttled back to a fraction of its advertised speed to be an adequate solution. You can complain to Apple but they will probably tell you that you shouldn't be trying to use your Mac as a PC.

mscm888: Try running Hyper PI with the Number of Processors set to 1.

Take a screen shot about half way through a 1M calculation of Hyper PI and ThrottleStop so I can have a look.

The P8700 has a default multiplier of 9.5 and an Intel Dynamic Acceleration multiplier of 10.0. The IDA multiplier is only used when a single core of the processor is active. When this is working properly, the CPU will rapidly switch back and forth between 9.5 and 10.0 while running a single thread of Hyper PI. If ThrottleStop does not report a multiplier higher than 9.50 during this test then that usually means your laptop manufacturer has disabled Intel Dynamic Acceleration in the bios. Unfortunately, if this is the problem you are having, I don't have access to enough older hardware so I don't know how to turn IDA on for you from within Windows. Maybe someday.

 

Thank you for your reply.. if i open it and change the thermal compound with a decent one do you think it can fix it ?
Other thing..i was pretending to buy an external graphic card (future with MSI GUS 2 release) do you think that the mac will run cooler and the throttle problem will be over ?

Regards and thank you.

 

In the 12" 2560P Owner's thread we've had users install quad-core i7 SB CPUs. One user SimoxTav shaved ~ 8 degrees off his peak temps by swapping ceramic thermal paste with a MX-4 compound. So yes, thermal paste and how well it's applied does make a difference. There is also a great 3830TG thread showing how users added more copper to their heat pipe to increase thermal dissipation. The 3830TG also suffers throttling due to an inadequate cooling system.

An eGPU will take the load off any iGPU/dGPU chip in your system so will take away one heat contributor. In one example of eGPU use (Sony Z1), we saw it's i-core CPUs then being able engage turbo boost longer as a result before TDP limits hit. Means it had faster overall performance.

 

Amazing, no more throttle!! works wonderfully, thanks dude!! M1530 works again

 

So I tried to play DIablo 3 on my m11x-R2 and it keeps lagging despite me making my settings really low and making the resolution really bad. Other m11x users don't seem to have a problem. I don't know much about computers and I just like to play with em but I've been looking at this throttlestop thing for a while and I tried it but it doesn't seem to be making any difference. My specs are:
m11xR2
i7 Processor with 8 gigs of ram...There are my throttlestop settings...I overclocked my cpu on bios to 152 because I wasn't sure how high I could make it, but can someone explain to me what I'm doing wrong? or what I need to do?

 

Hm....the image doesn't seem to be showing so here's a link to it Image - TinyPic - Free Image Hosting, Photo Sharing & Video Hosting

 

Hey. First, I'd like to thank you for your work, it seems to have solved a big problem of mine.
I have a question though : I have an alienware m15x (area-51), and before using throttlestop, I had big performance issues. I noticed that, while throttlestop is not running, my chipset clock usually goes down to like 25 or 30%.
So all was fine when I ran throttlestop to make it 100%. My question is : is it dangerous to make the chipset clock work at 100%, when it goes down to 25/30 without me doing anything? Is there a risk for my laptop?

Thank you for your awnser, and sorry for my bad english, I'm french

 

There's always a risk, if you will. But in this case it's so INSANELY small that it doesn't matter.

Setting throttlestop to be clocked at max settings does nothing else than consuming more power and making the laptop faster, easy as that just be careful with undervolting and such.

The reason for it to clock down automatically is because you are not doing anything that uses CPU power, so without throttlestop clocking it at 100%, it wants to save power and maintain it's "coolness".
While I don't see any change in my CPU, some others do.. but there's really no idea in not having the CPU clocked to the maximum on a laptop have fun and thank unclewebb

but as stated by unclewebb abount ThrottleStop

Read the above to be sure of what ThrottleStop does and what can happen in my case there's nothing really to go wrong hehe

 

Thank you for your awnser. I've tried it for one day or so, and it appears that my comp shuts down after two or three hours of using it. I don't know if it's usual - I guess not -. maybe there's something wrong with my fans or something? I did'nt notice any serious overheat, nothing more than 85-90° max.

So, if you have an idea of the cause of that problem, i'd be very grateful ^^ It may be just my laptop being somewhat old..

 

Did it somewhat shutdown before?

Make sure your power adapter can support the extra power you so extra put on it. Try running with a slightly lower clock/multiplier and without turbo.

Also check that you didn't play with the voltage as it teds to create BSOD's and crashes

If you can, please post a picture of your current settings so I or someone else might be able to help you better.

 

qtjoel: You seem to have ThrottleStop setup correctly. The only other thing to check is the Force TDP/TDC value in the Options window. That should be set to somewhere around 7 or 8. Try using one of the more recent versions of ThrottleStop from my signature. When gaming, have ThrottleStop running and check the Log File option so you will have a record of your CPU performance. When finished gaming, exit ThrottleStop so all the data can be written to the log file and then copy and paste the data to Pastebin.com - #1 paste tool since 2002! or upload the log file somewhere convenient so I can have a look at it.

There seem to be a variety of issues with trying to get Diablo III to run smoothly and the CPU is just one of those problems. When you see other users that are able to get this game running smoothly with similar hardware, ask them what GPU driver version they are using. That can make a big difference. Hard drive speed also seems to make a big difference.

Warser: Intel designed your chipset to run at 100% of its rated speed. It's mostly a Dell bug whenever it runs less than this. The older Core 2 processors will not run reliably if they start running at 80C to 90C. Pull your laptop apart and do what you can to improve cooling. Replacing the thermal interface material on the CPU and cleaning the heatsink and fan is always the best place to start. If you still can't get your CPU to run at a decent temperature then lower your multiplier a few notches. It makes a lot more sense to throttle your CPU a little bit by lowering the multiplier compared to completely making your laptop unusable by using Chipset Clock Modulation of 25%.

If you want to read about where Dell's throttling schemes went horribly wrong, check out this well done paper by Randall Cotton about his throttling E6400.

http://www.mediafire.com/view/?1gnwmozzy0w

Dell didn't put a lot of thought into throttling when they first started doing this to unsuspecting users.

 

Sorry if this has already been asked, but will this work with Sandy Bridge? the examples used are Clarksfields.
I'm wondering because the Undervolt guide here at NBR is so outdated and I'd like to undervolt my CPU...

EDIT: I just realized this is meant for stopping throttling (thus the name "throttle stop") and not undervolting...

 

Hi. I just cleaned the dust in my laptop one week ago, there wasn't a lot anyways. Sorry for my total newbiness ( ), but when you write "thermal interface material, you're talking about thermal paste, or actual components? ^^
Well , i've been playing around with the multiplier, and the chipset clock, and it seems to be working fine for the performances, no shut down for the moment, with a 75° max temp. I'll most likely try to change my thermal paste.
Anyways, you did an amazing job with this program, Thank you for your work

 

Ferrari353: ThrottleStop can be used to under volt Core 2 processors but unfortunately Intel removed this feature from their Core i CPUs. This is why you will not be able to find any software that lets you under volt a Core i CPU.

Warser: Thermal Interface Material (aka. TIM) and thermal paste are the same thing. Everyone calls it something different.

A lot of users with overheating laptops are using ThrottleStop to reduce CPU performance to better manage overall system heat. Less CPU heat or power consumption might allow the GPU to run at full speed longer which can result in better overall gaming performance.

Glad to hear that ThrottleStop has been useful for you.

 

Heya Uncle Webb big fan of your program, cant find a good home for my old Nehalem chip. I got an old i7-920xm, one of Aunty Shirley's I can donate for the cause. It was able to do 2.4ghz using TS under the N61jq but the trusty workhorse died recently. I got me a W110er now with an ivy, wow things have changed fast. Let me see if I can post it via somewhere neutral so I don't come off as a hacker/scammer.

 

Hi Marksman30k. What I really need now is for someone with a new Ivy CPU to do some testing for me. I might have to go out and buy an Ivy desktop CPU so I can do some hands on testing and get ThrottleStop up to speed for the next generation. ThrottleStop and the 920XM were like best friends.

If anyone has used ThrottleStop with a new Ivy CPU, let me know what works and what doesn't. ThrottleStop might need a minor tweak or two but it shouldn't be too hard to get it working 100% correctly with Ivy. Intel has a habit of making some minor changes from one generation to the next. That can screw up software like ThrottleStop that changes individual registers. You can PM me any info or screen shots you have or send them to the email address within ThrottleStop.

 

Hi Unclewebb
heres some data you might find useful.
My Laptop is a W110er with
-i7-3610m
-GT 650M Optimus
-8gb RAM

My laptop has been known to turn off the Turboboost when the 650m is active so I did all tests with iGPU only
The CPU has no problems hitting 3.1ghz on all cores even when the iGPU is loaded for a few minutes
The Turbo then enagages and fluctuates 2.9-3ghz after 3 minutes

When i turn on Throttlestop, even monitoring the turbo drops to 2.3 and fluctuates to 2,7.

When I activate TS, the clockspeed nosedives and fluctuates from 800 to 1200 mhz. The IGPU then no longer boosts. Intrestingly my system idles at 1200mhz but it drops to 800mhz when TS is active.

 

I will have to download the latest Intel Docs and see if there is any new info in there. Intel usually hides the good stuff from the public docs so I am thinking about buying some new hardware to see if I can get ThrottleStop updated for the 3rd generation of Core i CPUs. I might not do that until the fall though.

When testing, were you using the Windows high performance profile? The 800 MHz mode would be interesting for people that want extended battery life if I can figure out how to get it back up to full speed again.

Thanks for the pics Marksman30k. When I get back to working on project ThrottleStop, you will be at the top of my list for beta testing the new version. Your screen shots have already got me thinking about what Intel has changed and how to fix things up.

 

yeah, the comp was on high performance, its not possible for it to idle at 800mhz at stock without TS, though if TS is on the turbo gets neutered
I also got Prema's BIOS mod so I can control the TDP. I have set it to 55w and this has forced the Turbo to run at full speed but the downclock problem is still there

 

hi! i noticed after some gaming that chip% tend to go below 40% so the games become really laggish. when this happens and i check thecheckbox next to chipset clock mod it's on 100% again and the game runs well again. is there a way to force chip% to be always on 100%?

 

scorpeeon: How do you have ThrottleStop setup? If you have it turned on and Chipset Clock Mod is checked and set to 100.0%, doesn't that work to prevent throttling? Show me a screen shot and a log file so I can see what the problem is. The XPS 16 series has a solid reputation for throttling. ThrottleStop has helped out many XPS 1645 and XPS 1640 users. Make sure you have taken your laptop apart and cleaned out the heatsink and fan first. That and the latest bios is a good idea for the XPS 1640.

Marksman30k: I think Intel changed the internal layout of these new CPUs. Your problem might be something simple like ThrottleStop is only modifying the registers for half of your cores or something simple like that. As soon as I have both the time and money for some new hardware, I will put improved 3rd generation support at the top of my things to do list. ThrottleStop covers a wide range of Core 2 and Core i CPUs so it would be great to see it cover one more generation of Intel's CPUs.

Hi my girlfriend plays Diablo 3 on her laptop and it sometimes the FPS drops alot and it becomes unplayable in crowded areas, after viewing the Diablo 3 forums i noticed a post where alot of people are having the same problem. In the post they mentioned this program and for alot of the people it solved there issue

FPS SOLUTION - Forums - Diablo III

I posted her laptop specs above, when she opens the program she set the multiplier to 17 which is the max it can go. And ingame it seems to of stoped the problems. Im just wondering if there is anything in more detail you could tell us about todo with the multiplier and what Turbo does?

 

Using the Turbo setting lets your Core i5-430M use the Turbo Boost feature that Intel included with these CPUs. Turbo lets your CPU run faster. That's not a ThrottleStop overclocking feature, that's just the way Intel designed these CPUs to operate. The problem with many Acer laptops when gaming is that this feature causes the CPU to run too hot because they used an inadequate CPU heatsink and fan. Acer owners found out that the only way around this was to set a slower CPU speed by selecting a reduced multiplier ( 17 ) in ThrottleStop. This disables the Turbo Boost function.

Less CPU heat being created by your laptop helps avoid thermal throttling so a slower CPU surprisingly results in a better gaming experience because your laptop graphics chip is not forced to slow down to a crawl. An over heating graphics chip can also force your CPU to slow down to a crawl so avoiding this by using a reduced multiplier is a good thing.

Acer needs to do a better job supplying proper air flow to their laptops so users can run their GPU and CPU at their rated speed with full Turbo Boost enabled like Intel intended. That's what owners paid for. Kind of like paying for a Ferrari but when you get it home you find out that the transmission is locked so you only get to use first gear. Throttling while playing a common game like Diablo III is just bad design on Acer's part.

 

Thanks for the reply that cleared alot of things up for me , one more question about Throttlestop. Is there anyway i could affect my GPUs performance or is there any need?

 

LOL just figured it it wasn't actually turned on, i just assumed it was because when the chip% went down and i checked it to be on 100% it was immediately back on 100% and the game became from "really laggish" to "pretty smooth". sorry for my ignorance
so i guess when i turn it on it should automatically force to be on 100% right? will try that way next time.

i have latest bios installed, this is actually not my first case with throttling, had some problems with it about almost a year ago (see here), you also helped me out back then.

i took it to dell service back then, they investigated the problem then called me like the next day that the problem is fixed. they just cleaned it and after that they said they ran 3dmark06 for several hours without throttling, and as i tested it it was really much better even when running prime95 and furmark simultaneously it really ran pretty stable without throttling, sometimes it happened but it only went down to like 80% instead of the previous 37.5%.
so cleaning really does heavily matter which also means my throttling's cause is more likely overheating than actually power problems due to the 90W charger.

anyway now it tends again to go as low as 37.5%, maybe it's time for another cleaning, but your program definitely seems to be working and helping a lot. if i turn it on next time and it can maintain 100% chip clock, it would be really cool, maybe i wouldn't even need cleaning for a while

thanks for your continuous support.

 

@unclewebb

Hi, I have intel core 2 duo T7300 acer aspire 4920g. I'm having a problem in my game. My fps is dropping randomly to 15-20 and will go back to normal (50 fps) after a few minutes. I tried changing both the "minimum and maximum processor state to 85%" in power management and it seems to fix the problem. There's no fps dropping anymore.

But i found this "throttle stop" and want to try it, maybe it can increase my fps more and make my cpu runs at its maximum power making my game more smooth.

What settings or checkboxes should I tick/apply to make my cpu run at its maximum power?

Thanks in advance.

 

tetran: Start by setting Windows back to 100%. Put a check mark in the ThrottleStop - Set Multiplier box and maximize that and then put a check mark in the Chipset Clock Mod box and set that to 100.0%. Make sure to click on the Turn On button in ThrottleStop and you should be good to go with your CPU running at maximum speed. You can check the Log File option in ThrottleStop so you will have a record of your CPU while you are gaming. You can go back after you are finished gaming and exit ThrottleStop so you can have a look to see if there were any throttling problems. Upload the log file somewhere convenient or copy and paste the data to Pastebin.com so I can have a look at the numbers if you want my opinion.

Yep, turning ThrottleStop ON is always a good place to start!

Nice to hear from a long time user that has got more life out of their XPS 1640 with the help of ThrottleStop.

 

unclewebb, can't wait 'til you can get your hands on an Ivy Bridge. Too bad you live so far away otherwise I'd let you use mine for a bit to work out the Ivy Bridge.

 

@unclewebb

i did what u said but while I was playing for about 30mins the game became laggy my fps became 5 and my computer suddenly restarted. Here's the log

throttlestop - Pastebin.com

 

Your CPU is getting up to 98C which basically means it is bouncing off the thermal throttling temperature set by Intel. Thermal throttling = slow CPU or slow GPU or both. You didn't turn on GPU monitoring in ThrottleStop but I can imagine that if your CPU is over heating then your GPU is over heating too. Right at the end of your log file it shows clock modulation throttling set at 12.5%. When a CPU is overheating, the CPU can over ride any ThrottleStop settings and slow down like this to prevent any damage. That's why your FPS slows down to a crawl.

Acer does not include an adequate heatsink and fan with many of their laptops so you can not run the CPU and GPU at the same time at their rated speed. All you can do is some at home engineering to try and find a way for your laptop to run cooler. The heatsink and fan have to be spotlessly clean and you will have to redo the thermal paste with the best paste money can buy. You might need to find a way to tighten the heatsink against the CPU if possible. You could also use a cooling mat and every other trick in the book so you can try and run your laptop at the speed that Acer promised you when you bought it.

ThrottleStop can only do so much. It can't fix a problem when a manufacturer has cut too many corners in basic design and cooling. Poor design is poor design.

HTWingNut: Thanks for the offer. It's possible that Intel has added some more hidden lock bits to the Ivy Bridge design to block software like ThrottleStop. Something has definitely changed. Without access to the full Intel documentation, ThrottleStop development could be over.

 

I have a N43SM with an i5 2450M, I disabled EIST and C1E. Set TPL to 40 and 45, clock mod+chipset clock+multip is 100% and turbo.

Problems with it, running 4.10.

-Disabling C1 does not stop throttle when CPU is idle
-When F@H and Furmark is run at the same time, CPU throttles to 800MHz. Temperatures are safe though

Any ideas how to fix

-Thanks in advance

 

EIST usually needs to be enabled in the bios and enabled in ThrottleStop so that ThrottleStop can work properly. I am not sure why so many users like to disable EIST. Most users disable this because they don't understand it. If you have a Core i mobile CPU and it is not an XM or Extreme CPU, you can not lock the CPU to a fixed frequency when it is idle. These CPUs need the deeper sleep states like C3/C6 to be turned on. When you disable all the C sleep states, Turbo Boost will also be disabled and your CPU will run slower.

If you really want to disable everything you will need to go into the registry to do this. You will end up with no Turbo Boost and your laptop will run hot as hell when idle and it will drain the battery in record time because it won't be able to idle down in one of the various C sleep states. A few have tried this "mod" but I don't know too many owners that want to do this long term.

Is your laptop plugged in when testing with Furmark? The problem is that some laptops are poorly designed and are not capable of running the CPU and GPU at full load at the same time. If your laptop is not physically capable of delivering enough power to the CPU and GPU during this sort of stress test then there is nothing that ThrottleStop is going to be able to do to help. I would suggest returning your laptop and trying to find one that is better built. There are a lot of poorly built and poorly tested laptops being sold every day that are not capable of delivering their rated performance.

Does your laptop have BD PROCHOT enabled? Asus uses this feature on many of their high performance laptops. It allows other things on the motherboard to send a signal to the CPU to tell it to throttle. You can try disabling BD PROCHOT but you run the risk of damaging your laptop. I have to assume that Asus has decided to throttle your laptop for a reason. They might be trying to protect some under designed component on the motherboard from getting damaged if the CPU and GPU are allowed to run at full speed at the same time.

 

Heres the logs of my 2 wPRIME runs

 

Hey, I just have a few quick questions.
Few weeks ago I downloaded Throttlestop to help with overheating of my Dell Xps15, (reaching temps of 95c) so I used Throttle to bring the multiplier down to about 20x (2670qm i7). Worked fine for a little while. Recently throttlestop has been inactive. No matter what settings change the multiplier is stuck at 8x. Regardless of whether or not set multiplier is checked or not. I'm not using any other program that might interfere with the integrity of the program. Between the initial setting that I found acceptable with Throttle, I haven't tweaked or modified anything. Any ideas?

 

Invidosa: Do you have EIST - SpeedStep enabled in the bios and in ThrottleStop? That is required so ThrottleStop can control your multiplier.
Hope that helps. If not, you will have to wait until I get some new hardware to play with so I can continue development of ThrottleStop.

 

Goody data

TS 5.0 works even when not active
Full boost now
the best part, the CPU boosts now when the GPU is active
holy crap

91 degrees lol, i can see why they disabled CPU boosting

Unclewebb...you....are...a....legend

I speak on behalf of all the W110er owners: Thank you, we are in your debt.

 

That is great news Marksman30k. The version 5.00 beta should be good for a month or so if anyone else wants to do some testing. The only change so far is to support the new 3rd Generation Core i Ivy Bridge processors so if you do not have one of them, there is no need to download this beta.

 

THX unclewebb for all your hard work & Marksman30k for testing!

 

Wow this is amazing!! Great news really gj unclewebb and Marksman30k!
