The ThrottleStop Guide

Thanks yes i think it reset it properly, just wondering cause after i tried throttlestop i noticed my CPU didnt go above 1.8Ghz on battery even though its a I7-3740QM, but the shop i bought it from informed me its part of the power saving settings for the laptop.

 

I have a HP laptop containing a Core i5-2410M processor. When I select the "C7" button to look at core and package C states I noticed that the core C states shown are C3, C6, and C7 - which makes sense. However, the package C states shown are C2, C3, C6, and C7. To the best of my knowledge this processor doesn't support a package C2 state. The field does get filled in, as do the others. What does this mean? What is the package C2 state?

 

Hello all,

I got this problem with Battlefield 3 that is related to throttling i guess.


This what it looks in my log file and in Throttlestop. It started to be like this when i overclocked my gpu a bit.
How is this possible that either gpu or cpu is throttling when the temperatures are looking ok?
I just can't get the solution maybe somebody can help me.

Sorry for my lame english.

 

Good question. Intel doesn't talk very much about the C2 Package sleep state but it was introduced in their 2nd Generation Core i CPUs (aka. Sandy Bridge) and it is also available in their 3rd Generation Ivy Bridge CPUs. This box will show -- on a first gen Core i CPU since monitoring of the C2 Package state didn't exist back then.

I found out about the register in the CPU that keeps track of the C2 Package State in the Intel® 64 and IA-32 Architectures Software Developer’s Manual.



ThrottleStop reads this data from MSR 0x60D in the newer CPUs and if ThrottleStop is displaying something in the C2 box then I am pretty sure your CPU package is spending some of its idle time in the C2 sleep state. The next gen Haswell CPUs are going to have a pile of new C States available but that is still a secret.

Edit: Using RealTemp T|I, my 3570K is spending about 30% to 35% of its idle time in the C2 Package sleep state.

http://img59.imageshack.us/img59/8586/packagec2.png

The combined C2 + C3 + C6 + C7 package residency time accounts for 98.1% which seems reasonable to me. I will have to assume that the rest of the time the CPU package is either in the C0 or C1 state.

dominielus: Your screen shot definitely shows some throttling. This is typically caused by temperatures or is sometimes power related. When you start overclocking your GPU, that increases power consumption and that can increase the temperature of your voltage regulator on board. BD PROCHOT stands for bi-directional processor hot. This allows other things on the motherboard to send a signal to your CPU which forces it to throttle to the minimum multiplier because it thinks it is too hot even when it is not too hot. It kind of looks like that is happening to your laptop. ThrottleStop allows you to disable this signal path but this is strictly at your own risk. I have no idea why your motherboard is doing this. The engineers are likely trying to protect some under designed component. Better to throttle than burn out a motherboard. Many users turn off BD PROCHOT and everything continues to run just fine without any of these slow downs. If you are feeling lucky, turn off BD PROCHOT and see it that makes any difference.

 

Thanks so much for your answer - and for the utility!.

I guess the datasheet for the 2nd and 3rd generations of the i series processors are incomplete because they don't document a package C2 state. Obviously, though, there is a package C2 state (or some equivalent undocumented state). It wouldn't be the first time I've encountered a difference between processor behavior and documentation.

 

The Intel® 64 and IA-32 Architectures Software Developer’s Manual calls this register the Package C2 Residency counter so the C2 Package state definitely exists. I had a look in the datasheet and there is a picture of the various C states that these CPUs can go between but they left out C2. I guess their datasheet diagram is the simplified version.

On my desktop board you can disable the Package C States in the bios. When I do this, ThrottleStop shows 0.0 for all of the package C states even though the individual cores are still being allowed to use C3 and C6. It just blocks the entire CPU package from dropping down to any sleep states. I don't have any options in the bios to enable C7 but I have seen this working correctly on some Alienware laptops with a modified bios that enables C7.

 

Thanks for the additional information. I think this proves that the C2 residency counter is definitely keeping track of a low power state. Logically, though, it isn't really a package C2 state as there is no such thing as a core C2 state for these processors - so it's somewhat of a misnomer. I remember reading in a document from Intel (sorry, I don't remember which one) that when cores are in a C3 state core voltage can be lowered more when only one core is below C3 than if more than one core is. I wonder is they have separated this condition out and are using the C2 residency counter to track it.

 

I have a problem with Throttlestop. It happens both with version 4 point something and also with the latest 5.00 version. I have a Asus G50VT with an X9100 SLB48, Windows 8 64-bit (with Start8 to hide Metro) and I have it set for 12x multiplier, which is 3200MHZ, given 266MHZ quad pumped FSB.
But, when I restart the computer, on POST it displays as 3.6GHZ (13.5x) and when I get into Windows it shows as that speed as well on CPU-Z and a voltage of around 1.33V instead of the usual 1.25V. Temperatures verify that it's way overclocked. So something is messing up the tables (P-states, whatever it's called).
When I launch Throttlestop again it re-applies 12x and 1.25V. But what is causing it to super overclock upon reboot? It obviously doesn't do that on hard resets like going into hibernation or shutting down, turning on.

It may have started, 80% sure that it started after I upgraded from win7 64-bit to Win8 64-bit.

Is the P-state table stored anywhere on the hard drive?

 

Is it possible that CPU (i5-2430M) will throttle down without overheating itself? I'm using Throttlestop, and when I play Battlefield 3 or Deus Ex, the CPU throttles down although the temperature is max 89C. Only thing i can do is setting multiplayer to 25.

 

ickibar1234: When you are using the ThrottleStop Unlock feature and you increase the multiplier too high and then you change your mind, you MUST click on the Reset button before you click on the Save button and before you exit ThrottleStop or reboot.

Unlocking the CPU is a powerful feature so you need to be very careful when making adjustments. To use this feature, only increase the multiplier as much as you need and do not go any higher. The maximum unlocked multiplier value gets written directly to the CPU and some laptops do not reset this register properly when you reboot. If this is the problem, the only way to reset the CPU is to power down, remove the battery if you have to and do not run ThrottleStop until you have deleted the ThrottleStop.INI file so you can start again from step 1.

Go back to the bottom of page 147 and start reading.

http://forum.notebookreview.com/har...31329-throttlestop-guide-147.html#post9001698

alice43 was also having problems but once he learned how to use the Reset button, I think everything is OK.



Be very careful before clicking on OK in the above window. In this example, the new maximum multiplier will be set to 11. If you reduce the multiplier to 10 or 9 and click on Save and exit ThrottleStop, the maximum will still be sitting at 11 because you did not Reset the maximum multiplier. The maximum multiplier and the current multiplier are completely separate. I wish there was a simpler way to control this but Intel uses 2 different CPU registers to control this feature so it gets a little confusing when users have different profiles with different multipliers.

dominielus: Laptop manufacturers throttle their CPUs for a variety of reasons. Throttling a CPU before it has reached its official Intel throttling temperature is common. Throttling can be triggered by the CPU or GPU temperature or by the on board voltage regulator or randomly for what appears to be no reason at all. Post a screen shot of how you have ThrottleStop set up if you are having problems.

Some laptops are so poorly designed that you can not run both the CPU and GPU at their rated speed at the same time without the laptop over heating and shutting down. If this is the case, you are forced to do what you are doing and that is slowing your CPU down using ThrottleStop to prevent it from overheating and throttling. What laptop model do you have?

 

I am not using the Unlock feature of Throttlestop, I'm just using it to bump up the Vcore a tad and using SetFSB to increase the FSB from 266MHZ to 289MHZ at stock 11.5x multiplier = 3.33GHZ.
With the current configuration (see pic), upon restart the BIOS shows the CPU speed at 3.86GHZ, or approximately 289MHZ FSB *13.5 x multiplier. -_EDIT:WRONG

What's wrong? I read from the bottom of page 149 onwards but I'm not using the Unlock feature.

http://i909.photobucket.com/albums/ac295/danwat1234/throttlestopconfiguration.png

--
EDIT: When I only use setFSB but don't run Throttlestop on startup, then restart, clockspeed is back to stock 3.06GHZ (11.5x, 266MHZ FSB) upon POST. So above statement about 3.86GHZ, 13.5x @ 289MHZ is false.
Really when I use both throttlestop and setFSb and restart, upon POST: 14.5x, 266MHZ. =3857MHZ, so FSB resets upon restart but multiplier gets cranked up somehow. Confirmed FSB is reset to 266MHZ upon restart after messing with FSB setting in setFSB (or not running it at all), still 3.86GHZ upon restart.

 

Can you please upload and share a link to the 3.00.1 version?

I tried downloading it from the Tech Inferno link but it gives me an error even after getting the 5 quality posts in.

I have a dell studio 1558 with core i5 430m , ati 5470 . I'm having fps drops in dota 2 .
I heard dota 2 is not properly optimized for turbo boost .


I read the guide but i'm not sure what settings to use .


Can anyone help me please .

 

Thanks a lot for this great tool uncleweb, I believe I can finally get my Dell XPS 1645 to work as a normal laptop being.

Below is what I have done so far and some questions regarding my settings

• Cleaned the inside free of dust and particles
• Reinstalled windows and set windows to performance settings disabling all the good stuff

Evan after all this when I have 3 browsers and some apps open at the same time (As I am a web developer / designer), the laptop starts to lag so bad that I feel like throwing it out the window. I spent so much on this machine last year and this is what I get. Trust me I aint going with dell next time.

I have throttlestop installed and like you said, it is at my own risk so could you please guide me what settings to use? I do have that new 130w adapter plugged in and the latest bios installed. What checks should I select. What about EIST etc?

PS: I am using throttlestop 5.00


I WOULD REALLY REALLY APPRECIATE YOUR HELP HERE ...... !!!!

 

soulreaver: The best thing you can do is turn on the Log File option so you have some data that shows what your CPU is doing when you are having these problems.

Another thing you can do is post a screen shot of how you presently have ThrottleStop setup. That makes it a lot easier for me to make some recommendations.

Generally for your laptop, I think you have to check Set Multiplier and set that as high as possible so it says Turbo, check the Chipset Clock Mod box and make sure that is set to 100.0% and then click on the Turn On button and you are done. EIST should be checked too. Minimize ThrottleStop and see if there are any improvements.

As recently mentioned, if you are having throttling problems, it might be related to your power adapter. Even a brand new adapter does not guarantee that it is working correctly. Show me some log file data if you want me to have a look.

kantri: Same as above. I need to see data so I can see what the problem might be. "Not properly optimized for Turbo Boost" sounds like some misinformation you read in a forum.
Turbo Boost just makes your CPU run a little faster. All applications are optimized for that and can benefit from a faster CPU. Many Dell laptops use chipset based clock modulation throttling. That's usually the problem but you need to run a log file to confirm this before trying to solve a problem that you don't fully understand.

andros_forever: I can't think of a reason why anyone would want to run ThrottleStop 3.00.1 compared to ThrottleStop 4.00 or 5.00. The newer versions have several significant improvements and support both Core 2 and Core i CPUs. If there is a difference in your results, can you let me know what it is?

 

Hi unclewebb, just wanted to thank you immensely for your awesome software! After some googling I was able to bring down my max temps while playing games from the mid 90's to the high 70's (by just disabling turboboost).

Thank you!

(in case someone is wondering, on a w520, i7 2820qm and Q2000m)


1. Install tpfancontrol, but make sure to set ManModeExit to 110 instead of the default 80, in its ini file (this keeps manual mode running and stops it from defaulting to smart mode itself)

Before starting your game or power hungry tasks: set tpfancontrol to manual mode. (reset it to smart mode about 5 to 7 minutes after you're done with heavy computing to make sure to allow things to cool adequately)

2. Install Throttlestop.

Start it, press 'Turn On' button.

Tick 'Set Multiplier' and keep increasing the values till you see TURBO in that box instead of numbers.

Tick 'Disable Turbo'

See the max temps decrease from 92 degrees in Crysis 2 to only 77 max.

Remember to turn throttlestop off and set tpfancontrol back to smart mode after you're done. And then thank unclewebb!

 

Dear unclewebb ,

First of all, thank you for this amazing tool - I am using it on my laptops and workstations for a looong time!

I have a question about, well, workstation use:

First, the introduction: I have a dual-CPU setup at home (dual Xeon E5 2687W with ASUS Z9PE-D8-WS board), and the board's UEFI sucks when it comes to fine-grained performance control. To make matters worse, since some time ago, when I configure the options fully, CPU stays at 1200 MHz for some reason, so I have to manually disable SpeedStep in UEFI and use software control of the clock.

So, what I am doing is - I am using ThrottleSTop 5.00 and configure a profile for my HPC use, which will force the turbo mode to the max, while I am profiling my HPC applications. Another profile manages power nicely, and keeps CPU in the lowest P-state when it is not used (substitution for broken HW_ALL control of SpeedStep of my ASUS board)

However, during debugging of my code I noticed something really weird - in my code last 16 threads (belonging to NUMA node 2, the second CPU) always run a bit slower - just a tiny bit, but enough to make me wonder...

I looked deeper into this, and the my theory is following (and, please correct me if I am wrong) - I would assume that ThrottleStop is managing the first CPU (CPU #0), while CPU #1 stays on maximum non-turbo frequency (or, even worse, @1200 MHz if I re-enable SpeedStep in my broken BIOS). This creates a slight difference (and, Windows, of course, does not report the frequency of the other CPU) which gets my other 16 threads to run a bit slower.

And, finally, the question: does ThrottleStop manage clocks of all physical CPUs (sockets) or only the primary CPU in a multi-socket (NUMA nowdays) system? If it does manage a single (primary) socket, is there a chance to maybe create an option to control all physical CPUs at once?

 

ThrottleStop was only designed for single CPU systems and has mostly become a tool for laptops. I don't have access to any multi-CPU systems for testing purposes so I don't intend to release a multi-CPU version of ThrottleStop.

How big is the difference in performance that you are seeing?

My other software RealTemp 3.70 is somewhat multi CPU aware but it can only read 4 cores of each CPU on a dual CPU system. I know this used to work but I have never done any hands on testing of this feature so I don't know what bugs or limitations there might be.

Download Real Temp 3.70 | techPowerUp

Unzip this program and create 2 identical folders with RealTemp.exe and the RealTemp.INI configuration file in each folder. In the first folder, open the RealTemp.INI file and add this line:

Skull=1

and in the second folder, add this next line to the RealTemp.INI file.

Skull=2

Now you can run two instances of RealTemp and it should be able to read 4 cores from each CPU. If you see anything else interesting, let me know. I might be able to cobble together a one off version of ThrottleStop someday to help you out but it is at the bottom of the things to do list at the moment. I don't have enough time for any significant one off projects like this any more.

 

So why does running Throttlestop cause my computer, upon restart to boost the multiplier from the default 11.5x which I use when in Windows, to 14.5x on my X9100 CPU? Throttlestop is not unlocked, I am just using it to boost up voltage just by 1/4 of a volt and leaving the multiplier untouched. Using v5.0

 

ickibar1234: I already answered this question on the previous page.

http://forum.notebookreview.com/har...31329-throttlestop-guide-151.html#post9055080

The voltage and the multiplier are contained in the same register within the CPU. It sounds like you unlocked your CPU, you set the multiplier too high and then you didn't push the Reset button. This higher unlocked multiplier probably got saved to the INI file. You have to push Reset and then Save your new settings to the ThrotteStop.INI file. Copy and Paste the information from your INI file if you still don't understand this.

 

OK I did that. I pressed 'Reset', then 'Save", then I upped the voltage from the default 1.238v to 1.275v and hit 'Save' again. Upon quitting and launching Throttlestop again the saved changes are lost. I'm back to my stock CPU voltage and multiplier. I've also tried to lock the CPU after configuring the voltage bump and then saving but the changes still do not stick, whether or not I lock or keep Throttlestop in the unlocked position after making my voltage bump change and doing reset first of all every time I try to configure it.
I no longer have the 14.5x multiplier on reboot now, in other words it goes back to stock on reboot which is nice but when I go to run the program again, it's still stock.

The Reset button is designed to Reset your Core 2 Extreme CPU to its default maximum multiplier and default maximum VID voltage. Generally, you only need to use this button after you have over clocked or over volted your CPU too high.

If you increase the multi to 14 and then decide that is too much, you need to push Reset. That will take you back to 11.5 and then you can try again and increase it to only 13 if you decide that is enough. If you go up to 14 and then go back to 13 without pushing Reset, the default maximum multiplier for your CPU will still be sitting at 14 and that value might also get saved in the ThrottleStop.INI file. If you exit ThrottleStop and Do Not Reset FID/VID on Exit is not checked, it is going to try and set your CPU to its new default maximum which is 14.

The VID votlage works the same way. If you Unlock your Core 2 Extreme CPU and increase the voltage too high, you must push the Reset button to go back to the default maximum multiplier and VID voltage settings. Both of these are in the same register within the CPU so they both get set or reset at the same time.

Some motherboards automatically reset these values in the CPU when you re-boot but some motherboards do not. If your motherboard does not reset these maximums, then you will have to do this yourself with ThrottleStop before you re-boot. When you completely power down, the CPU should be reset.

These are the important lines in the INI file.

The first 4 lines are the settings for each of your 4 profiles. The FIDVID is only for Core 2 Extreme CPUs. This should contain the maximum FID and VID from the 4 profiles.

0x4B2A -
0x4B - FID (multiplier)
0x2A - VID (voltage)

The first 4 is the code for the half multiplier. The letter B in hex is equivalent to 11 decimal so when you combine those values you get the 11.5 multiplier. This is just a request. If your CPU does not support your request, the CPU will ignore these values.

The 12 multiplier should show 0x0C. C is equivalent to 12 and the 0 means the half multi is not being used.
12.5 = 0x4C
13.0 = 0x0D
13.5 = 0x4D

Does this make sense?

The next 2 digits represent the core voltage. Once again this is a request and if the CPU does not support this voltage, it will ignore your request. Here's the formula:

Voltage = 0.7125 + ( 0.0125 X VID )

0x2A hex is 42 decimal and when you plug that number into the above formula you get Voltage = 1.2375

In Profile 2 you have 0x2D = 45 which is 1.2750

It looks like ThrottleStop did save your increased voltage but you must have been in Profile 2 when you pushed Save.

The only other problem I see is that TJMax is set to 98. For an X9100, this is supposed to be set to 105.

ARK | Intel® Core

ThrottleStop uses this value to determine your CPU core temperature so if it is set too low, your CPU core temperatures will be reported too low.

If you are having any problems, look in the INI file to see what values were saved and hit the Reset button to get back to your default settings if something bad got saved.

 

Thanks for this guide! Makes it very easy to make tweaks on locked (asus) laptops. +1

 

Excelent guide! Thanks for the amazing work.

But i have a question:

Is it possible to set the VID lower than 1.000v? I'm using a Core 2 Duo T5800 and i still got some throttle in this voltage at 100% CPU usage...

Thanks again

Edit:

i changed in ThrottleStop.ini to 0.9500 but my processor does not accept that... got stuck in 1.000v
But how the f@*& ? Why i got throttle when 100% cpu? I just changed the thermal paste/cleaned the cooler and i'm using an external cooler...

I just upgraded my notebook also, i changed the RAM memory 667 to 800mhz (yeah my mobo supports it) and changed to a 64 bit OS (windows 8). Before that upgrade i solved the "throttle problem" undervolting to 1.050v.
That could be the problem? A faster memory? Is the memory speed related to the cpu speed?

 

If the ThrottleStop voltage adjuster only goes down to 1.00 volts then that is the lowest VID voltage that your CPU supports. The newer 45nm Core 2 CPUs can usually go lower than that when SLFM is enabled but I don't think your CPU has that option.

.What is this throttle you are talking about? What sort of testing are you doing and have you run a log file that shows what the problem is? Post some more information and some screen shots of how you have ThrottleStop set up and what problem you are noticing.

 

My laptop is MSI ge620dx and it is known for throttling, though MSI release BIOS that suppose to fix it, but it don't.
This are my settings in ThrottleStop:


Only when I set ThrottleStop like this the throttling is gone:


And i didn't have the courage to turn of the BD PROCHOT

 

I had to change to Vid to 1.0375 because 1.0000 was giving me Blue screen.

Some examples when i got throttle:

Right now i'm compiling a boost library for MSVS and watching a HD 720p movie on youtube, i got every 2:30~min a 20 seg throttle... Then i have to underclock CPU FID to 8x (max is 10x)

 

Two years and a format later, any my XPS 1645 still throttles extremely when it gets warm after I used hibernation or shutdown... still need to sleep the laptop to fix

 

I have a same problem.....i have cheng my cpu i5 430m to an i7 740qm....my temp its go to 100c.......tehre is eny solotion for this

 

Hi
Asus N55SF
i7-2670QM
nVidia 555m GT
8 GB RAM

I've noticed a FPS drop in demanding games after playing for about 5 minutes. With TS I saw that the CPU was throttling down as I continued playing until it reached multiplier of 12.
Even with BD PROCHOT off and multiplier set to 22, (2.2 Ghz, base clock speed for this CPU) the multiplier drops to 12 and drags the FPS below 20.

http://pastebin.com/fLAFbFBz
This is a short run of Crysis 2, BD PROCHOT off and multiplier set to 23.
The second the game loads, there is a slow decrease of the multiplier value.
Any thoughts?

 

Aralizer: Did you look in the log file at what temperature your CPU is running at? 98C is way too hot. That is the thermal throttling temperature where Intel slows your CPU down to prevent it from being damaged. ThrottleStop can not be used to disable this. Your CPU is throttling for a good reason. it is too damn hot!

When was the last time you opened your laptop up and thoroughly cleaned it? Have you ever replaced the thermal paste between the CPU and the heatsink? I can only imagine that your Nvidia GPU is just as hot or maybe hotter. If you go into the ThrottleStop Options window you can usually turn on Nvidia GPU monitoring so that information will show up in your log file too.

Yes there is a solution. Put the Core i5-430M back in your laptop. The Core i7-740QM puts out a lot of heat. If you installed your heatsink correctly then I guess your laptop does not have the ability to cool a Quad core processor.

DuranXL: Looks like Dell never got around to properly fixing the XPS 1645. At the temperature that the XPS 1645 likes to run at, I guess you should be happy that your laptop is still running after 2 years. Does cycling Clock Modulation on and off in ThrottleStop or adjusting the percent make any difference when it gets stuck like this? In the war to throttle your CPU, looks like your bios is winning against ThrottleStop.

 

Well, it's only 73c at the time of throttling... It's not that hot, for some reason it just starts to throttle. No, changing clock mod on/off or whatever doesn't change anything. TS just can't overpower the bios. It's the same problem we PMed about 1.5 years ago. When I give it any input (keyboard) it throttles.
It's not that big of a deal since I can fix it by sleeping and then resuming. Just shows the problem is still there now.. with newer drivers, newer bios, new win7 install.

But yeh, it still works. It's in fact 3 years old already
Installed a SSD and it's pretty fast right now too! Thinking about buying a 9-cell replacement battery because mine won't last 30min watching a movie.
But it's so heavy already

 

Hi everybody, this is my first time checking out ThrottleStop. I recently purchased the Lenovo IdeaPad Y500 in my sig. I've heard from others that the i7-3630QM in this model disables Turbo Boost and goes down to 2.4 after the CPU goes above 90 C. Once CPU reaches 105 C, it will go down even lower to 1.2 GHz before complete thermal shutdown at 115 C. Will disabling BD Prochot in ThrottleStop allow full Turbo Boost up the point of thermal shutdown?

 

105C is the thermal throttling temperature built into the 3rd Generation Ivy Bridge CPUs by Intel. There is no software that can over ride this hardware safety feature. Turbo Boost is automatically disabled when you reach the thermal throttling temperature so disabling BD PROCHOT will not likely change anything.

Instead of converting your laptop into a small oven, why not pull the thing apart and replace the thermal paste and do whatever it takes to try and improve the cooling. Some laptops are begging for some re-engineering.

 

Thanks for the info unclewebb. I understand that it is impossible to achieve Turbo Boost after 105 C due to Intel's design but what about in the temperature range between 90 C and 105 C? Without TS the 3630QM disables Turbo Boost and downclocks to 2.4 GHz as soon as it passes 90 C. Basically, I would like to use ThrottleStop to raise the throttling temperature from 90 C to 105 C temporarily for benchmarking purposes. I understand the detriments of having such high temperatures in the long run.

Based on what I know, the cooling system in the Y500 isn't the greatest and barring a complete cooling system modification, which is beyond my abilities, there isn't much that can be done to improve thermals. Others have reported little to no improvement, in one case even higher temperatures, from repasting. I guess there's only so much you can do with one shared fan between a hot CPU and hot GPU.

 

I'm trying to OC my 3720qm, but I'm starting to grow to hate turbo boost, and missing the old days of solid multipliers
Changed the multipliers in bios to 40 for one core, 39 for 2, and 38 for 3 and 4 active cores, but it never seems to hit those speeds. I tried to use throttlestop to force that speed, it doesn't work either. What is interesting, is that just benath the turbo setting for multipliers, it goes as high as 40, but I never see 40 take effect if "forced". In fact, none of the multipliers i ask to set take effect. What can I do to fix this? I'd like to push at least 3.8 constant across all 4 cores. Heat is not a problem, I've never broken past 85

 

Hi there.
I just got a new Dell M6700 with an i5-3360m.
Is it possible to have both cores running at max turbo speed with Tstop?
Thanks

 

octiceps: I am not sure what method Lenovo is using to limit Turbo Boost once you hit 90C. When running ThrottleStop, is Turbo Boost disabled when you hit 90C. Show me a screen shot of ThrottleStop at this temperature so I can have a look.

technos: Turbo Boost can be limited by temperature but for your CPU, it is usually power consumption that is the limiting factor. Are you using an unlocked bios? How far can you increase the Turbo Power Limits in the bios? Are these values locked when you are in Windows or can you use ThrottleStop to adjust these limits? There is also a time limit for Turbo Boost. If you were running something like a wPrime benchmark and your CPU was fully loaded, it is normal to see the multiplier drop after you reach this time limit. The CPU is forced to reduce power and it has to drop the multi to get back under the Long term power limit. A QM CPU is not an XM CPU. It sounds like you are coming up against the limits set by Intel and there is not anything any software is going to be able to do about that. You're right that the Core 2 Extreme CPUs were a lot easier to work with. For them you just set a multi and away you went.

inspiron_geek: The Core i5-3360M has a maximum multiplier of 35 when a single core is active and as soon as both cores are active, the maximum multiplier drops down to 33. Those are the maximum limits set in the hardware by Intel. You can not use any software to go beyond limits that are hard coded into the hardware. If you exceed the long term turbo power limit, you might not be able to reach these maximums.

 

ThrottleStop 5.10 - Beta 2
http://www.techinferno.com/downloads/?did=59



This is a time limited beta version. I don't have access to a wide variety of hardware so any feedback is appreciated.

- added adjustable Turbo Boost Time Limit for the unlocked CPUs.

- added an iGPU Throttle flag on the main screen that on my desktop CPU, seems to indicate when the Intel GPU is being throttled due to reaching the power limit. There is also an iGPU Log box that will be checked whenever the Intel GPU has been throttled so you can have a look at this box to see if any throttling was recorded while you were gaming. The documentation does not seem to be accurate so let me know if this feature works like this on the mobile CPUs.

- the new EX PROCHOT box should indicate if an External source is triggering the Processor Hot signal to the CPU and if this is forcing the CPU to throttle.

- added a FLEX VID setting in the TRL window so users with unlocked CPUs can boost the turbo voltage. Be careful with this feature. Unless you have an Extreme CPU and are pushing a very high multiplier, you should leave this setting at zero.

- changed the Set Multiplier value so it includes what value is being sent to the CPU. Instead of Turbo, ThrottleStop might show something like 40 T which indicates that you are requesting the 40 Turbo multiplier from the CPU.

- added a Task Bar option so you can minimize ThrottleStop to the Task Bar.

- added Windows 7 and Windows 8 Notification Area Icon compatibility. If you have any problems, use the Notification_Area_Cleaner.zip file to clean out your Windows icon cache. This handy utility can be found here and does not require a reboot.

Great news to see the new version, unclewebb, although it's a shame that it's time limited. I'm quite curious to check the IGP Throttle flag as well as EX PROCHOT.

When will this version expire?

 

Thank you unclewebb for the new version.

Is the following an IBT problem? Prime95 doesn't do that. I'm talking about the C0% column.

I think when Linpack testing on a hyper threaded CPU, you get the highest GFlop results when hyper threading is disabled. Here's what Intel says when running Linpack on the Linux OS.

Known Limitations of the Intel(R) Optimized LINPACK Benchmark

In your example, 1 thread from each core is being fully utilized while the other thread is mostly idle.

Stasio over on XtremeSystems has updated LinX and combined it with some of the more recent Intel Linpack binaries. His MediaFire link was working last time I checked.

LinX - A simple Linpack interface - Page 34

You might want to give LinX a try to see if it can load all 8 threads for you so you can compare performance and core temperatures.

tribaljet: I think the betas are good until the end of April. Lots of time so users can do some testing.

Beta 2 has one minor update to block the Turbo VID adjustment window when a CPU is locked by Intel or the bios.

Uhm, it was parking cores. I overtweaked it. Just few days ago, I tried yet another core unparking utility, while I had used some registry edits before. So it was in a bad state. This screenshot seemed weird to me because in the past, on light load, every second core was used - I guess the "real" cores. Now it didn't unpark these cores in the screenshot no matter what.

All fixed now, all cores churning, false alarm. :thumbsup:

 

I have an old Core Duo with me, do you think throttlestop can overclock Core Duo? Since the description states its only for Core 2 Duo and above.

 

The only Core 2 Duo CPUs that ThrottleStop can overclock are the Extreme CPUs like the X7800,X7900, X9000, X9100 and QX9300.

ThrottleStop may or may not work correctly on your older Core Duo. ThrottleStop has no ability to overclock one of these early CPUs.

GrofLuigi: If you are bored, compare the GFlop results with different amounts of core parking. As mentioned, you usually get the highest GFlops in Linpack testing when you are not using hyper threading. Each thread in the CPU is equally capable so as shown in your screen shot, it doesn't matter whether the first or second thread in each core is fully loaded. The results will be the same. On a hyper threaded quad core processor, 4 threads of Linpack usually gives better GFlop results than 8 threads. Linpack is so optimized that it is one of the very few benchmarks where less is more.

 

Do you think there are any progs can that overclock Core Duos? Since there is no option in Bios.

 

@unclewebb: Yes, I have read about that Linpack behavior. But usually I don't have enough patience to leave it running enough time to complete cycle(s). This case (with core parking) was messed up because there were different registry edits - I disabled core parking before by setting minimum percent... in power management options, and the program changed maximum percent (or vice versa), so it was in a very bad state. Luckily, I track any changes in my OS, so I could quickly revert.

@Captmario: RMClock can do it probably, maybe also CrustalCPUID. But if the BIOS is locked (and usually it is), you can not overclock it, just do better (smarter?) multiplier management and/or undervolting. Often it is a good thing that you can't overclock, otherwise the cooling system in the laptop that was designed for one temperature would melt and the CPU would be fried.

 

The only way to overclock your CPU is by increasing the front side bus speed. You can try using SetFSB but support for your laptop is doubtful.

 

is there any way to force max cpu clocks? I've tinkered with the settings but to no avail so far. I have this unusual problem where when I start a game, my CPU at first loads but then stops "triggering" any load. So lets say if I'm playing Starcraft II or Guild Wars 2 or Crysis 3.... first few seconds the game will be at ~40-70fps.....and then very quickly go down to like 3-10fps and stay this way.
