The ThrottleStop Guide

terminus123: You need to run a ThrottleStop log file while gaming so you have a record of what is going on. If you have an overheating problem then you need to take care of that problem first. Have you ever opened your laptop to clean it out?

You can not force maximum CPU clocks on a 2720QM. The maximum speed it can run at varies depending on temperature and power consumption and time. It is normal for this CPU to slow down a little when the short term turbo power limit runs out. It's not normal for it to drop from 50 fps to 5 fps unless it is over heating or thinks it is over heating.

Upload your log file to www.pastebin.com so I can have a look. Turn on Nvidia GPU monitoring in the ThrottleStop - Options window before you start logging data. It might be your GPU that is over heating.

 

Thanks.

Yea, I actually recently opened up my notebook to clean out some lint and stuff out of the fans and heatsink. Though didn't do a good job at it (it's hard!). Didn't make any change though.

Anyways I posted a log of me playing Starcraft II. I started the log from the load screen. terminus123, log file in SCIfrom throttlestop - Pastebin.com

 

Hi unclewebb, sorry I'm replying so late. I had previously inquired about using ThrottleStop to prevent Turbo Boost from disabling after my CPU passes 90 C. Turns out, I was wrong about Turbo Boost disabling after 90 C; it is disabled as soon as perform this test, which is a pretty common one: Running Prime95 and FurMark simultaneously. When just running Prime95 by itself, my i7-3630QM will run at it's maximum 4-core Turbo (3.2 GHz) and power consumption between 45-50 W:



However, as soon as I fire up FurMark, Turbo Boost is gone and the CPU drops to 2.4 GHz and power consumption also drops to 25-30W:



This seems to happen regardless of temperatures on the CPU/GPU and disabling BD Prochot in TS didn't do anything. Any ideas?

EDIT: I found out that there was a BD Prochot setting in my BIOS as well. It was enabled even though I had already disabled it in ThrottleStop so the two seem to operate independently of each other. Anyway, I disabled it in BIOS but still no change.

 

Have you tried putting a Check Mark in the Set Multiplier box? You need to do that to have some hope of turbo boost working correctly.

terminus123: Your laptop is running too hot. It is reaching the thermal throttling temperature where it must throttle to protect itself from reaching the thermal shut down temperature as well as to protect itself from being damaged. Even so, the log file does not show any significant throttling. Your CPU is doing quite well considering the temperature your laptop is running at. It would be a good idea to replace the thermal paste and do whatever you can to improve cooling.

 

Wow looks like that did the trick. Temperatures keep climbing on the CPU but Turbo Boost stays active.

 

Hello all! I have an Acer Aspire 5742G with an Intel Core i5-480M processor and an Nvidia GeForce GT 540M coupled with an integrated Intel GPU (boo!). I suspect that my CPU isn't performing as well as it should be since I experience low frames in plenty games where other users with the same GPU & CPU have higher frames.

How would I go about using ThrottleStop to make my CPU run at its advertised Turbo Speed?

Cheers, from a desperate swede stuck with a ty laptop! xD

 

Hi: I just got my computer back from the repair shop. I have a Gateway Fx7805U, and I put the X9100 CPU on it. I am a noob on OC and under clocking, so I am not sure how I can do it correctly. If anyone can help me with a quick and easy explanation, please do.
Thank you all

 

Hi unclewebb,

I've spent a good few hours getting to know the program, benchmarking, and reading the documentation you have provided. Your suggestion to tick Set Multiplier and setting it at 32, 33, or Turbo along with ticking EIST eliminated all CPU throttling on my Lenovo. I can now run Prime95 and FurMark simultaneously without FID dropping below 30 on any thread until the CPU reaches thermal shutdown ternperature (the GPU runs much cooler).

One thing I've noticed is that my system will immediately perform a thermal shutdown when DTS on any core reaches 0, which is 105 C. This is strange because you said that 105 C is the thermal throttling temperature not shutdown temperature for Ivy Bridge. I don't know if this is because I am forcing the Turbo multiplier but there is no preliminary throttling at all before shutdown. One second I'm pulling 3 GHz+ across all four cores and the next second the system is turned off.

BD Prochot seems to have no effect for me whether adjusted here or in the BIOS. I don't get any throttling with it either way as long as the multiplier has been set.

I'm not sure what C1E does and the documentation wasn't very clear. Toggling it doesn't seem to have any effect that I can see in ThrottleStop. Is there any reason for me to have it one way or the other for my particular CPU?

I like the ability of Power Saver to downclock from 2.4 GHz to 800 MHz when the CPU is idle. It seems like it would save a lot of power and increase battery life, but is there any performance impact from having it turned on? Technically, the processor will still be running at full power when loaded but my CPU scores in 3DMark 11 seem to be a few percentage points lower with Power Saver on. That could be within the margin of error though.

These are my current ThrottleStop settings. If anything doesn't look right please let me know and I appreciate all advice as I get the hang of this excellent tool.

 

octiceps: It is common for laptop manufacturers to set a thermal shut down temperature far lower than the Intel specified thermal shut down temperature. Intel has set the thermal throttling temperature to 105C for their mobile Ivy Bridge CPUs and the thermal shut down temperature is set to approxiimately 130C. They do this on purpose so the CPU can gradually throttle without it instantly shutting down. Intel thermal throttling works so well that this is almost always enough to keep the CPU from getting anywhere near the 130C shut down temperature which fully protects the CPU from any long term damage. The CPU slows down but keeps on running so a user does not lose anything that they are working on. Lenovo's decision to do a premature thermal shut down at 105C completely disables the incredible engineering that Intel has put into the thermal management of their CPUs.

Not all manufacturers use the Bi-Directional Processor Hot (BD PROCHOT) signal to trigger CPU throttling. If Lenovo is not using this then having BD PROCHOT checked or unchecked will not make any difference. It's also possible that it is being used but the trigger temperature from the GPU or voltage regulator might be so high that in normal use it doesn't ever get triggered. If a manufacturer has BD PROCHOT checked by default and it is not causing any problems then I would leave it checked. I am all for safety features as long as they do not prevent users from getting the performance that they were promised.

The Power Saver function was created to lower CPU speeds when lightly loaded to try and keep previous RM Clock users happy. Running a modern Core i CPU slow will reduce performance but it is not a great way to save power. If I was running on battery power, I would turn off ThrottleStop and let the CPU manage itself. The C3/C6 sleep states do a far better job to reduce power consumption without reducing performance. I recommend leaving the ThrottleStop - Power Saver box unchecked.

C1E is one of the low power CPU states. It was originally a good way to save power because it would lower the CPU voltage. Most laptops use the deeper low power states like C3 or C6 which do a far better job of reducing power consumption. If C3 or C6 are being used, your CPU will spend a very tiny percentage of time in C1E so it will be tough to notice a difference whether C1E is enabled or not.

That looks good. Intel considers any temperature less than the thermal throttling temperature (105C) to be a safe operating temperature. As long as you are comfortable with that, you will not hurt your CPU by using the turbo boost performance that Intel has built into their CPUs. The laptop manufacturers that have decided to disable turbo boost usually do this because they don't want users complaining about their laptops running too hot. Easier and cheaper to disable turbo boost than to include an adequate heatsink and fan.

 

Thanks for all the help! So I completely removed all lint, and put new thermal paste on the CPU. CPU most def runs cooler, I never see "throttling" ever on on HWInfo now. However, my CPU still does not initiate or keep load while playing games. Here is a throttlestop of me playing an entire mission of SC2. Intel i7 playing SC2, terminus123 - Pastebin.com

 

Can you try to explain this better? I had a look at your log file data and your CPU seems to be running exactly as Intel intended it to run. With a non-Extreme processor like a Core i7-2720QM, the multiplier that ThrottleStop reports is not going to be a fixed number like 30.00 while gaming. The amount of Turbo Boost these CPUs use can be varying thousands of times a second depending on how many cores are active at any instant in time.

A hyper threaded quad core 2720QM can process 8 threads at a time. It's a processing beast. The ThrottleStop C0% column gives a good indication of how much of your CPU is being utilized. The sad reality is that the game you are playing and most software is not multi-threaded enough to take advantage of what your CPU is capable of. A single threaded game will only be able to use one-eighth (1/8) of your CPU so the C0% will be 12.5% to process this game plus another couple of percent for Windows background tasks, etc. Your log file data shows me that the game you are playing is not able to take advantage of your CPU. That's a problem with the game, not the CPU. That's why your C0% is so low.

 

Hi unclewebb, I am having significant problems with the intel core i7 3635qm clocking down to around 1.5ghz during gaming and running 3dmark11. The result is that even though the cpu does not appear to be pegged hard enough to clock high, it is rampantly bottle necking the gpu performance. A quick fix that I thought of was to run prime95 in 1/8 threads in the background, this forces the clock to jump to either 3.2(turbo) or 2.4(when I disable turbo), and stays fairly stable there. When I run 3dmark11 normally I get around P2550-2600, and with single thread prime95 running in the background I get a bump to around P2730, which is a massive performance gain. I have though to shut down C-states with the Audio Processing profile from PreSonus, this also locks my cpu speed and it does not drop below 2.4ghz, however, albeit the 3dmark score remains at 2700, the result is that my temps rise 5-10C and power usage also takes a hit of about 5-10watts, than with C-states enabled and Prime95 running. Is there any way to tweak Throttle Stop to limit throttling so the cpu does not go below 2.4ghz while gaming, or is there a better application than will keep the cpu pegged at atleast stock frequencies while gaming? The fixes that I mentioned are both not ideal, one requires pegging the cpu with prime95 and this causes reduced cpu performance, the other causes too much heat and power consumption not great on a laptop with only 120w AC adapter. Thanks for all help.

 

Try checking Set Multiplier and setting it to Turbo. I had a similar problem and this worked for me.

 

I have tried to set multiplier and enable turbo, the multiplier value just caps the cpu at a particular value it does not stop it from clocking down, and turbo is enabled checked or not. The problem is with gpu performance when the cpu is clocked too low, on the physics portion of 3dmark the cpu clock to its highest point, without anything running in the background, but on other portions it clocks down due to underutilization. I have a gtx 660m.

 

Untick BD Prochot in ThrottleStop and also in your BIOS if it's there as well.

 

BD Prochot is disabled, and temps always remain under 70C so thermal throttling is not an issue.

Octiceps do your logs show the cpu being clocked at 2.4ghz throughout 3dmark run if not can you run prime 95 on one thread and see if your scores increase?

 

roteplex: When testing, make sure you are using the Windows High Performance profile in the Control Panel - Power Options and that your Minimum and Maximum processor state is set to 100% in this profile. Also make sure you are plugged in when testing. Can you post a screen shot of exactly how you have ThrottleStop setup? Upload a ThrottleStop log file to Pastebin.com - #1 paste tool since 2002! while you are running 3D Mark or while you are gaming.

Disabling all of the C states will make your CPU run hotter when lightly loaded and this will also disable Turbo Boost at the same time. I can't think of any good reason to do that on a laptop with a 3635QM.

Turn off all of your other monitoring apps and side bar gadgets while testing except for ThrottleStop.

For setting up ThrottleStop, check Set Multiplier and set that to Turbo or as high as it can go, uncheck BD PROCHOT, check EIST and make sure ThrottleStop is turned on and not just in Monitoring Mode. There should never be any need for running a single thread of Prime 95. If you are relying on another monitoring app for data then let me know what it is because many of them do not follow the Intel recommended monitoring method for Core i CPUs and their data can be very misleading. I can guarantee you that ThrottleStop will provide you with some high quality data when it is run by itself.

When set up correctly, even a tiny load is enough to get these CPUs up to their maximum Turbo Boost speed.

 

My log shows my CPU always above 3 GHz in 3DMark 11, usually at 3.2 or 3.3. My physics score goes down a little if I run Prime95 on one thread along with 3DMark. Can you try to run FurMark and Prime95 simultaneously and see if the CPU will stay above 3 GHz at all times?

I'm just curious, what does your TPL window look like? This is mine:



Turbo Time Limit for Limit #1 corresponds to how long in seconds the CPU will maintain full Turbo Boost after it has exceeded 45 W. Ivy Bridge CPU's are designed to Turbo for a short period of time even after they have gone past TDP. For some reason the limit shown here is half of what it actually is in testing. So 28 seconds here means that my CPU will continue to run over 45 W for 56 seconds before it throttles itself to maintain TDP. When I run Prime95 torture test on 8 threads, which causes 50+ W power consumption on my CPU, it will stay at 3.2 GHz for 56 seconds before throttling down to around 3 GHz to maintain TDP.

I guess if your limit is very shot or 0 then the CPU will automatically throttle when it exceeds TDP. Prime95 and other extreme CPU burn tests are usually the only ones I can think of that might cause that to happen but you never know about 3DMark 11.

By the way, Turbo Time Limits can't be changed in ThrottleStop, only in the BIOS, unless you have an XM CPU. Thankfully, I have an unlocked BIOS for my system and can increase Limit #1 up to 56 seconds, which is 112 seconds or almost 2 minutes in testing. I keep it at its default of 28 because letting my CPU exceed TDP for almost 2 minutes is guaranteed to make it reach thermal shutdown temperature since the cooling on my system is not great.

In the BIOS, Turbo Time Limit for Limit #1 is called "Long Duration TimeWindow" and for Limit #2 is called "Short Duration TimeWindow." Short Duration TimeWindow does nothing unless you have an XM CPU. If you can't find either then you probably have a locked BIOS and are stuck with whatever its default value is.

 

Hi im having a problem while gaming, my cpu max watt is 35 when im gaming my watts get up to 32 causing overheating then i used throttlestop to lower the multiplier to 18 (my max multiplier is 23) so my cpu will use less watts when gaming but it looks like the multiplier went down buttttttt the watts are still 35.
my cpu is an i3 2350m max tj is 85C the temperatures while gaming are :
83C.
75C.

 

Thanks for your detailed response Unclewebb and Octiceps, I have made sure there were no other monitoring programs were running and windows is set to High Performance, with Min and Max 100%. The problem may have to do with a power supply issue so I have ordered another one just to be certain. I have lowered my GPU clocks and tested again, I will post higher clocks as the difference there is much bigger but these will illustrate the issue.

High Performance

Prime95

C-States Off

The graphics performance is consistently higher on the C-state off/Prime runs, and I am not sure why, one thing that I noticed was that on lower gpu clocks the cpu does not go lower than 2.4Ghz, which is why I have ordered a new power supply.


Throttle Stop Setup

Is there a way to lock the cpu at a particular frequency without disabling C-states, I know this was possible in the Core2duo days with RMclock.

 

roteplex: Interesting results. You can lock a Core i XM CPU to a fixed multiplier but with the regular QM processors, you can only do this by disabling the deeper C States. As soon as C3 and C6 are disabled, you lose the Turbo Boost feature so it is not a good trade off. I don't think the CPU is the root cause of your problem though. An Intel Core i CPU can go from C6 to full turbo speed in about 200 microseconds so the low power C States should not be responsible for any significant difference that you are seeing.

During that benchmark there seems to be a lot of time where the CPU has nothing to do. Real games are generally not like this. They always load the CPU enough to keep it running at full speed. Have you done any data logging while playing a game?

Could you try doing some more testing and log your GPU data with GPU-Z. The GPU is probably down clocking to its 2D clocks and is not getting back up to the 3D clocks quick enough. This might be a driver issue. I am not sure what the latest software or registry hack is available to try and fix this problem.

When testing, instead of running a single thread of Prime 95, you can try running my Load Tester program. It is available in the RealTemp 3.70 download at TechPowerUp.

Download Real Temp 3.70 | techPowerUp

It also lets you fully load a single thread of your CPU but the advantage is that the Load Tester program does not consume as much power or create as much heat as Prime95 does. In theory, a person should never have to run a single thread of anything to get their CPU running properly but there are some special situations where doing this might be useful if there is a bad driver or some other problem.

 

I'm sorry to post here, but the forum over techinferno doesn't allow me to start a new thread.
My motherboard bios can't regain control over Package Power limit

Core i7 3770 (non K, T, S)
Gigabyte Z77X-UD3H

1. Enter Motherboard Bios, change TDP Limit to 95
2. Run ThrottleStop 5.10 Beta2
Package Power Limit Long is 79
Package Power Limit Short is 95
3. Change Package Power Limit Long to 77 from 79
4. Restart PC and enter Motherboard BIOS, change TDP Limit to 92
5. Run ThrottleStop again, Package Power Limit Long is still 77, Package Power Limit Short is still 95

Solutions I tried :
1. Windows Restore Service
2. Enter Motherboard Bios, change TDP Limit to "auto"
3. Reflash Bios

None of the above worked. Is the CPU MSR damaged?
I have also noticed that the Package Power Limit Short/Package Power Limit Long ratio isn't 1.25 when altered inside BIOS, is it the reason which cause the problem?

 

Can throttlestop be used to undervolt an i7 cpu on a Lenovo y400 with an unlocked BIOS?

 

No. Per the ThrottleStop manual:

Software adjustable core voltage is no longer available on the newer Core i7/i5/i3 processors.

 

Hi unclewebb,

I have a 4C/8T i7, the Ivy Bridge 3630QM. I've read your past advice about using the Power Saver option on Core i processors, but can't help wondering if it could actually save power vs Turbo Boost + C3/C6 only, because of the tendency for Windows to shuffle threads around and causing all 4 cores to be awake in turn.

On the other hand, would it be more beneficial to leave Power Saver off and perhaps turn on 50% Core Parking so as to keep thread-bouncing under control during light loads?

ThrottleStop does show 4.2-5 W using Power Saver vs 5-5.7 W without it. I am hoping that the wattage numbers are accurate so that I don't have to run any battery tests.

 

The power consumption number that all software including ThrottleStop displays is a number that is used internally by the CPU to control the Intel Turbo Boost feature. There are some situations where this number has nothing to do with actual power consumption. I would not depend on this number to determine the best way to set up a laptop for maximum battery run time. Doing some accurate power consumption testing is not easy. To do this properly, you would need to tap into the CPU socket and you would need to measure the current going directly to the CPU which is not very practical for most users.

If I was on battery power, I would exit ThrottleStop and I would let the CPU manage itself.

I have never done any testing of Core Parking so I can not help you with that. The C0% data in ThrottleStop is very accurate so you can keep an eye on that when adjusting Core Parking to see if it is making much of a difference.

 

Thank you unclewebb. I'll be testing out Power Saver mode when on battery power for now, using 8x/16x multipliers with 70% C0% threshold. In the past, it was possible to undervolt such that it made sense to stick to the highest possible FID on the lowest VID, but now it seems some trial-and-error is needed to decide if it's better to have lesser C3/C6 time at the lowest FID/VID or more C3/C6 time but at an FID which uses a higher VID.

I've read in a related thread that Core Parking is an OS feature which confines running threads to the same few cores, which may cause localised heating on top of decreased responsiveness. I'll be leaving cores unparked.

 

hi uncleweb.. ill buy a i5 3470 .. my question is.: can i set the TURBO multiplyer to be always same all the time ? I mean... for example.. 3.2 ghz stock..3.4ghz in turbo.. i want to to my i5 to always run at 3.4 (turbo mode) . can I do this with Throttlestop beta? or its depends on motherboard ? thanks in advance

 

Scouty: Click on the ThrottleStop TRL button and open up the Turbo Ratio Limits window. That window will tell you the maximum multiplier your CPU can use depending on whether there are 1 or 2 cores active. There is no software available that will let you run your CPU with the 1 core turbo limit when 2 cores are active. These limits are set by Intel. You need an unlocked Extreme processor or an unlocked K series processor to go higher than these limits. The maximum multiplier in your Core i5-3470 is locked by Intel.

 

thank you uncle... solved =)

 

Beta 2 has now expired.

 

May be an odd question but my 940xm runs at 25,24,16,16 and 62/62 at stock (I believe) and I'm just wondering if anyone has found a reduced power state (by lowering TDP etc) with still decent clocks?
Something like x14 on 4 cores with 55/55?

 

I didn't really get much feedback so I have no idea if any of the new features were of any use to anyone. Version 5.00 still works fine so most users have not been too motivated to upgrade to a newer version.

I might work on ThrottleStop some more next week if I have the time. The weather finally looks decent here so I might put this project back on the shelf for a while. Time to watch some playoff hockey.

fatboyslimerr: 16 is the default multiplier for your CPU. You can use ThrottleStop to use a multiplier less than that but why would you want to? There is no big power savings to be had by doing that. CPUs are most efficient when they are allowed to run at full speed.

 

Hello to all, and happy to find you. (sorry for my low English and low pc knowledge)

I have a laptop with CPU i5-2450Μ, and i am trying to learn if i can undervolt him...( only undervolt- nothing else)

But i have been confused and i need your help...

1. Someone said :
"Mobile CPU's cannot be under-volted"

2. Here in Intel they says :
"Our most popular family member is now unlocked"
That means that it can be possible ?

3. Today, i readed this solution from you about Throttle Stop,
and it was like a sunshine for me,
but until i readed the previous page, where someone said :
"Software adjustable core voltage is no longer available on the newer Core i7/i5/i3 processors."
-------------------------------------------------------------------------------------------------------------------------------------------------------------
Gentlemens, i have spend many ours searching the net,
but my low english knowledge and my low pc knowledge,
dont let me understand if this is possible or not...

Also, i try to understand what exactly Supercharge is,
and how relate is with Under-volting...
Because, as i read for Supercharge, i cant find what difference does have (if there any) with under-volting.

Can please someone help me ?
This will help me to stop searching and reading about this thread (if it is not possible)
or continue to searching and reading (if there is a way and make it possible)

Thank you very much, and i will appreciate for your help and your time.

 

It is NOT possible to under volt Core i mobile CPUs. No software exists to do this. You used to be able to under volt the Core 2 Duo and Core 2 Quad CPUs but this is not possible with the Core i mobile CPUs.

Most desktop motherboards let you adjust the CPU voltage but the motherboards that are used in laptops do not let you do this.

The Supercharge option was for the first generation Core i mobile CPU that was installed in the Alienware M11x-R2. A Core i5-2450M is a 2nd Generation mobile CPU. The 2450M does not have the same features as the first generation processors.

The desktop K series have an unlocked multiplier. You can use the XTU program to increase the multiplier and you can increase the voltage but you can not decrease the voltage. The mobile XM 2nd and 3rd Generation Core i CPUs have the same feature. Adjustable multiplier but you can not lower the core voltage.

 

Thank you very much unclewebb,
now, i know !

One last question please...

I wonder if it is possible through BIOS

 

Hello
First of all - thnx for program. It works very good on my old T5800. It would be great to have a new little feature in TStop to connect power saver settings with profiles. I use two profiles with diffrent power saver settings. When I change profile I have to manualy change PS settings in Options. Once again - thnx for TS

 

I was playing around with ThrottleStop today on my desktop 3570K and I noticed a difference in the percentage of time the CPU was spending in the C6 package C State when idle.

Usually I get a C6 Package residency percentage in the low 60% range.



Today, for the first time ever, I noticed that it was hitting 97%.



There was an updated bios recently so I thought maybe it was that but finally I traced this change to having my Logitech G15 keyboard plugged into a USB3 port instead of a USB2 port. My conclusion is that the USB2 driver is junk and it is interfering with the CPU package spending as much time as possible in C6.

The power consumption number reported by ThrottleStop is based on the VID voltage and is generated within the CPU to control the Turbo Boost feature. There are times when this number might be similar to actual power consumption of the CPU and there are times when this number is completely meaningless. It showed a decrease from 7.0W down to 6.2W which is a 10% reduction in power consumption just by using a different USB port. Power consumption at the wall dropped from 54W to 51W.

Anyone interested in maximizing their battery run time should make sure that they don't have any crappy, poorly written drivers on their computer. When idle, if you are not seeing your CPU spending over 90% of its time in the low power C6 Package state then maybe it is time to ask the manufacturer to write some better drivers for their laptop.

makos: For desktop motherboards, you can adjust the core voltage lower in the bios. I have not seen or heard of any Core i laptops that let you lower the core voltage in the bios. I agree that this would be a great feature for Core i laptops but it doesn't seem to exist.

kukam-ga: For older 65nm Core 2 Duo CPUs, why not try RM Clock.

RMClock Utility. Products. CPU Rightmark

If you are using a 64 bit operating system then you will need to download a signed 64 bit driver called RTCore64.sys

http://forum.notebookreview.com/windows-os-software/435958-rmclock-win7-64-bit.html#post5537485

RM Clock was very popular when the T5800 first shipped. Unfortunately my time for programming is very limited these days so I do not plan to add different Power Saver settings for each profile.

 

Is that in any way related to hardware interrupts process?

It's okay - maybe in the future. I've tried RmClock, but TStop is much better for me

 

I hover at around 50-80% C6 on the i7-3610m in my w110er with a wall plug but it can idle at about 75% on C7 when on battery. Is this within acceptable parameters?

 

Marksman30k: I used to think 60% to 65% in the C6 Package state at idle was pretty good. I had no idea that something simple like switching from a USB2 port to a USB3 port would make such a big difference. I don't have enough data from enough different laptop models to know what is normal but now I know that 97.0% is possible on a lean system. I was running Windows 7 SP1 and Avast antivirus for the above test.

From the screen shots I have seen so far, I think laptop manufacturers all need to put some more effort into making sure that there are not any drivers on their systems that interfere with the CPU from going into C6 or C7. Some old driver code needs an update, especially with Intel introducing some more low power C States in their next generation of CPUs. Intel makes some great technology but it doesn't do much good if manufacturers are sloppy and are not taking full advantage of it.

 

What are the odds that my system (config in signature) will still throttle the gpu even with TS on? And is there something I can do?

How I tested for gpu throttling:

ultra performance power plan (dell specific that limits throttling) - also tried with high performance and balanced, intelburn test + unigine running in the background and monitoring gpu frequencies with msi afterburner and cpu frequency with both hwinfo and ts main window.

The cpu will not go over 90 degrees and the gpu stays in the range of 70 degrees.

Even after first 2 minutes after starting both programs, the gpu will throttle back to 450/1200 (from stock 850/1200). Running any test independently, does not result in any throttling (nor cpu or gpu)

Any insight on this? I had a similar config (i7 2960xm+ 7970m) in my former MSI and despite the temperatures were much higher it did not throttle one bit by using TS. Could there be some sort of protection in this m6600?

Thank you for any input.

 

I know there's a few laptops where their graphic drivers are provided by the manufacturer and not by Nividia/AMD. However, such drivers are not known for being updated frequently, if at all.

 

Hi guys,

I just bought a second-hand ASUS, a N55S with i7 2670QM.

The laptop seems to be in perfect shape, but I bought it for playing, and I am really scared with the temperature of the CPU! Because it reaches 90 degrees very easily, and I don't need to be playing hours for that, it does it very fast. And, I am using a coolmaster base with a big fan under the laptop, and it's not even summer here in Spain!

Anyway, while searching for info, I came up with this comment from other user in other thread: "Well I configured throttlestop to work at 2,4Ghz when gaming and now I t doesnt go above 85max There is no noticable performance lost so its great! I might overclock the GPU as it has excellent temps (never more than 74C) to get even more juice out of this baby "

I have read the first post wih the guide, but I don't entirely undestand how could I do that, limiting my CPU so, when the gaming mode is on, I don't suffer such incredibly high temperatures.

At the moment I am seeing this, after 5 minutes playing, 10 minutes ago:



Could you guys tell me the steps to limit my CPU? Do you guys believe I could realy fight high temperatures with this measure? Do you think a feature called "turbo boost" that, I believe, is present in my laptop, could get in the way of this solution?

Thank you a lot!

 

I re-read the first post, still unsure how to cap the maximum ghz while I play, so temperature does not escale..

 

Click TRL and set the multiplier values. Multiplier at 4 cores...higher = higher temperatures.
You'll need to set TPL settings to provide enough power to whatever OC you run.

 

But how do I know which setting is the correct one?

If I do that, and turn this software on, it won't go up that number, even if it can, or if "turbo boost" or whatever is called, is on?

What I need, is to limit the ghz, so temperature does not go up....

Sorry for being such a n00b....

 

Go back to the picture you posted and click on the Turn On button. ThrottleStop can not control your multiplier until you do that.

With Set Multiplier checked and set to 24, your CPU will not be able to run as fast and this will reduce your heat.

If your CPU is idle during that screen shot, open up the task manager and see if there is any junk running that you can get rid of.

It would be a good idea to pull this laptop apart and give it a thorough cleaning.

 

Thank you!

I actually bought arctic mx-4 paste, and I brought it to a store, so they open it, clean it and put new thermal paste in CPU and GPU.

They opened it with me there, but there wasn't time enough for them to mount it all again so, I was unable to see if the new paste did anything to improve temperature. For what I was able to see, the fan was not very dirty, and there was a lot of thermal paste, maybe not so much in the middle of the processors, it had squeezed to the sides.

I will test it today when I go to the store, but if that hasn't improved temperature, I can only try your software so it controls the maximum velocity of CPU... my other option, make some holes in the laptop, so air can go through!!!!

Question: why 24? Because 24 x 99,78mhz is roughly 2400mhz, and that is good for limitind that i7? That's the reasoning behind it?

Will that limit turbo boost also?

 

The user in the other forum used a 24 multiplier so I thought that you wanted to do the same. You can use whatever multiplier you want.

Intel says the maximum safe operating temperature for your CPU is 100C so it is a good idea to keep your CPU a few degrees cooler than that.

The default speed for your CPU is 2200 MHz so the default multiplier is 22. If you disable all turbo boost your CPU will not run faster than 2200 MHz. If you set a multiplier greater than 22 than your CPU will be using some turbo boost. If you set ThrottleStop 5.00 so it says Turbo then your CPU will use as much turbo boost as possible. This is the normal setting. I encourage everyone to use this setting as long as their laptop is not too hot. You don't like the temperature of your laptop so you can use a little less.

If it was my laptop, I would work on improving cooling so you can use full turbo boost whenever it is needed. You paid for the turbo boost feature so you should be able to use it. Some laptop manufacturers do a very poor job when it comes to keeping the CPU at a reasonable temperature.
