The ThrottleStop Guide

That's cache clock ratio performance status.

Usually there should be hardware limits that hopefully power off the system if it can not handle it. If not then anything from failure to burning the house or city down. It's usually not in the laptop manufacturer's interest to have their laptop cause a fire, but sometimes fires do happen. Doesn't sound like your pushing that laptop too hard though.

 

EarlySpanky - If you raise the power consumption of a CPU, it makes sense that the core temperature is going to go up. As I like to tell people, 95°C is a big number but Intel says the "maximum safe operating temperature" for your CPU is anything less than 105°C. You are still within that limit so no worries.

Changing the TDP / TDC allows your CPU to run Prime95 at its full rated speed. You probably don't have one other application on your hard drive that increasing TDP / TDC is going to make any difference to. They were probably all running at their full rated speed already because they were under the default power limit.

Your CPU is running at its maximum rated speed so there is nothing else you can do to go faster. If you need to go faster, look into buying a 920XM if your board supports it.

Dufus - Thanks for the info about MSR 0x621. My 4700MQ shows 0x22 = 34.

 

Your welcome as always.

620 can be used to set max and min performance but of course if you want to use the unlocked bins that needs to be enabled too.

Usual behavior is for the Cache ratio to follow the Core ratio but you could, if you wanted to, run the Cache ratio at a higher ratio than Core ratio.

For example here's with the Cache ratio set for 36x only while the Core ratio is at 8x.

 

Thanks for the reply mr Webb . So i guess i'll stick to what it is now, i can't imagine how much it would cost me to change the processor.

 

Hi unclewebb
I have problem with turbo on my laptop. the cpu is core i 7 4500u. the default clock speed is 1.8. it is supposed to go to 3.1 GH. when i'm on desktop it is ok. but as soon as I go to a game like diablo or bioshock it goes down to 1.8. whlie the game is lagy and obvious it needs more processing power the turbo does not care. I checked the temp with throttle stop, it is around 60. i used Throttlestop to luck it with TPL option but it is only lucks on 2.4 GH no more but the performance is far better than 1.8. can you tell me how can get must out of the CPU?

 

Try disabling EIST and C1E if possible. Also deselect TDP throttle and TDP log.

 

minith - The maximum speed for a Core i7-4500U is 3.0 GHz but that only happens when a single core of the CPU is active. When both cores are active, the maximum multiplier and speed decreases.

ARK | Intel® Core™ i7-4500U Processor (4M Cache, up to 3.00 GHz)

The U in 4500U means that Intel designed this CPU as a low power CPU. Temperature is rarely a limiting factor. Intel decided to limit these CPUs based on power consumption. If ThrottleStop has helped you get a little more performance out of one of these CPUs then that's great but ThrottleStop cannot turn a low power 15 Watt U CPU into a 37 Watt or 47 Watt regular CPU. There is only so much you can do with software.

I would suggest trying ThrottleStop 7.00. There are a few more options that might help you out a little more. If your CPU supports under volting, that can reduce power consumption which can extend the amount of Turbo Boost that is available.

In your screenshot where the round circle that says TDP Throttle is lit up, that means your CPU is throttling because it has reached the power limit.

When using ThrottleStop, disabling EIST can prevent the Set Multiplier feature from working. About the only time I suggest disabling EIST is when you have a Core 2 Duo and you are trying to lock it into Dual IDA mode. As long as the Minimum processor state is set to 100%, EIST enabled or disabled doesn't matter.

Modern Core i mobile CPUs spend an insignificant percentage of time in C1E because they would rather be in C3/C6/C7. Having C1E enabled or disabled is not going to make any difference.

 

Sorry guys, a stupid question... is Throttlestop fully compatible with win8.1?

 

Yes it is. And Trottlestop is one of the greatest software ever made. :thumbsup:

 

Thanks for destroy my stupid paranoia!

 

Who is paranoid

 

I'm having some issues with ThrottleStop 7.0b3

I can't for the love of god set multiplier for the desired amount and my TDP Level Control over the TPL menu is grayed out locked so I can't change that either
no matter what I do my CPU runs at fixed 24x and it's overheating! Help?

 

Probably because you have one of the terrible U processors.

 

Thank you for your constructive feedback... -_-

 

alexhawker has a point. The problem with the U processors is that Intel has given laptop / tablet manufacturers complete control of these CPUs. How a 4210U operates in one device from one manufacturer can be completely different than how it operates in a different device. The result is that a consumer has no way of knowing how one of these Intel CPUs will perform until after they buy it and do some extensive testing. Sadly, most consumers are in the dark about the U CPUs and don't find out that it is not fit for their purpose until after it is too late to return it.

ARK | Intel® Core™ i5-4210U Processor (3M Cache, up to 2.70 GHz)

Lor_Azut - You mention that your CPU is overheating but in your screenshot, I don't see any evidence of that. Intel 4th Generation CPUs are designed to run HOT. When one of these CPUs exceeds the maximum safe operating temperature, it will throttle and slow down to prevent any damage. When you have reached this maximum temperature, the box in ThrottleStop that shows PROCHOT 98 will have a check mark to indicate that this has happened. That box is not checked and your maximum reported core temperatures have not exceeded any limits. Your CPU is hot but it is not yet overheating. Intel sets the maximum temperature for these CPUs to 100C and your manufacturer has reduced that in the bios to 98C.

When you first ran ThrottleStop, do you remember if the TDP Level Control - Lock option was already checked? If you are not 100% sure, delete ThrottleStop, turn your device completely off, remove the battery and then start it again and run ThrottleStop again. This will force ThrottleStop to recreate the ThrottleStop.INI configuration file. I just want to make sure that you didn't accidentally Lock the TDP Level setting to 0 and then accidentally saved this setting to the ThrottleStop.INI file.

The default speed for a Core i5-4210U is 1.7 GHz so the default multiplier is 17. The maximum multiplier is 27. When the CPU is between 17 and 27, the Set Multiplier option in ThrottleStop might not give you full control of your CPU. This is the range where Intel Turbo Boost is in control of your CPU. When you go into the TRL (Turbo Ratio Limits) window, are those multiplier values locked? If they were unlocked, you might be able to control your maximum multiplier with these values if the Set Multiplier option is not working. Are you using the Windows High Performance power profile like you are supposed to be using when running ThrottleStop? On some CPUs, EIST - SpeedStep has to be enabled in the bios for the Set Multiplier feature to work correctly. If you check the Disable Turbo feature, does that limit your multiplier to 17?

Let me know if you are able to find out what the problem is. Without having your device in my hands, all I can do is guess at what might be going on. Do you have a laptop or something else?

Edit - Can you post a screenshot of the C States window when your CPU is idle? I just want to make sure that these are working correctly. When the C States are not enabled, you can end up with a lot of extra heat in any modern device.

Here's an example of how values in the TRL window can override the Set Multiplier value.

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

 

I'll take the screenshots u need right now, FYI the SS u saw was from the PC on idle state.

 

FYI I updated my BIOS before taking this new screenshots u requested not sure if that will do anything for the values.





Edit: regarding ur questions when running SWTOR my temperature went to 91ºC so I thought that was not right and turned my notebook off.
TDP Level Control I checked myself but now that I updated the BIOS it's is back to normal
Yes it stays @ 17x if I disable turbo.. also now with updated BIOS even when it is NOT checked when I run SWTOR it STAYS @ 17x
So i'm totally and completly lost!

 

Forgot to mention..if you see the screenshot u'll notice that throttlestop was monitoring only (turned off) but when I did the test on SWTOR it was actually turned on it's just that I redownloaded it and forgot to turn on before taking the SS's

 

Intel says that 91ºC is a safe operating temperature for your CPU model so why are you turning your notebook off? Intel's 4th Generation CPUs run hot and most notebook manufacturers use heatsinks and fans that are barely adequate. The average Joe user demands a fast but thin and quiet laptop so that is why CPUs run at sky high temperatures these days. If your CPU reaches 98ºC, it will start to throttle and slow down just enough to maintain the peak CPU core temperature just under that limit. A notebook can run for hours at this temperature and often times, the slight slow down due to thermal throttling might not even be noticed. This is all part of Intel's master plan. They want users to be able to get maximum performance out of their CPUs. They would prefer that users can use their computers without having to worry about what temperature the CPU is running at. Intel typically sets a maximum thermal shutdown temperature to 125ºC to 130ºC. Something has to go seriously wrong before you will ever hit this temperature.

If for whatever reason, if you still don't feel comfortable with your laptop operating at these high temperatures then I would suggest limiting it using the PP0 Power Limit option. Intel has moved away from limiting based on speed to limiting based on power consumption. In the Turbo Power Limits window, check off the PP0 Power Limit option, check off the Clamp sub option and then enter a power limit value. Maybe 10 or 15 would be a good starting point. Avoid checking the Lock option. As soon as you check that, your values will be locked into the CPU and you will need to reboot and perhaps remove the battery before the CPU will reset itself. If you use Lock, you will also need to delete the ThrottleStop.INI configuration file before starting ThrottleStop to make sure the CPU doesn't lock itself over and over again. Most people in this thread are interested in maximizing CPU performance. If you want to throttle and slow down your CPU for better heat control, you will need to experiment with those settings. You can also try adjusting the PP0 Turbo Time limit up a little or leaving the Clamp option unchecked. I would suggest running ThrottleStop with the Log File option checked so you have a record of your CPU's performance while gaming.

If you plan to limit your CPU with this option, I would check Set Multiplier and set that to the Maximum value and click on the Turn On button to take ThrottleStop out of Monitoring mode. If you are going to use ThrottleStop; either use it to monitor your CPU or click on Turn On and use it to actively adjust your CPU. Going back and forth between the 2 different modes can end up leaving the CPU locked in a random or unpredictable state. You also need to use the Windows High Performance power profile when actively using ThrottleStop.

In your previous screenshot, it looked like the Package C States were not being used. This might be a bug in the bios or the manufacturer might have decided to disable the package C States for better stability or for some other reason. I think with your updated bios, this has been fixed.

 

Hey Uncle Webb

I had the following question to you: Wonder how it goes with the development (the work) with and establish this function (adjustment of cashe and voltage adjustment), then I really wish that this feature is in trottlestop.


This is a previous question I had for you earlier this summer:
From post: #2205 Hi There are some things I'm wondering how to do it in trottlestop. I have used Xtu for and overclock my i7-4930mx (4x42), but now I have started with trottlestop. How can I add processor Cashe offset? It must be increased +17mv, because I have to use a higher offset when my pc is more stable. Every time I start up my machine (with automatic trottlestop boot) then I get processor Cashe ratio of 39, but want and have it at 38 for stability. How can I do this. I have turned off the boot of Xtu when my computer starts. Automatically start of trottlestop instead. To my cpu is important that i use increased Cashe offset (+17mv) and have Cashe ratio of 38. Hope you can help me with this. Thank You.
http://i.imgur.com/DDdoEhu.png

From post: # 2206 GeorgioB - When you have questions, post some screen shots. I need to see the main ThrottleStop screen as well as the C States window. Were you testing when idle or fully loaded? What CPU model do you have? Screenshots tell me what I need to know.

papusan - Unfortunately some of the features you are looking for in ThrottleStop are still on the things to do list.

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

Cache voltage and cache ratio will be fully adjustable when version 7 is finished but not sure when that is going to happen. Maybe next month.


Thanks for a positive response.
Papusan

 

I have thread through countless threads, including the 200 plus page one we are on now, i watched Mr. Fox's youtube video , and went onto other websites about throttle stop. The consensus on this site is I would be getting higher 3dmark scores and performance if I started to use throttle stop. I have downloaded it. I think i have version 6 and 7 and i have no idea what things i should check off. Guys did a great job explaining what each thing does ect., but when i go to set mine up im lost.

If someone out there has a i7 4930MX with their alienware 18 could you post your throttle stop pages. I think it will end up being 4 screen shots and then atleast i can just copy yours if your settings are doing the job correctly. I did try google, read most of mr. foxes posts by searching for throttle stop and went on his youtube channel to watch the throttle stop video.I'm still having trouble. Thank you if anyone takes the time to snap a couple screen shots for me. its very appreciated.

 

papusan - Nothing has changed. I have not done any ThrottleStop programming in months. I still plan to get back to this project and probably very soon but I am not sure when. FInding a new job so I can afford to eat is at the top of my things to do list. That and watching some baseball next week.

jtravapd8578 - I recommend ThrottleStop 7.00 beta for your 4930MX. Overclocking is a step by step process. Mr. Fox makes it look easy but it takes a lot of work and a lot of testing to achieve anywhere near those kind of results. His settings might be significantly different that what works best for you.

You need to understand what the numbers in the ThrottleStop log file mean. If you don't have a thorough understanding of the 4930MX then ThrottleStop is going to look a little confusing or even overwhelming but it really isn't. There are usually not that many items that need to be changed to improve performance. The infinite testing of new settings is the time consuming part. Post some pics and start asking specific questions about what you are trying to accomplish and what you don't understand.

 

Good luck with your job hunting and I hope your favorite basebal team win games , so you get more energy for your trottlestop programming hobby. But do not forget us, who love more opportunities and push our hardware to the limit. Good Luck :thumbsup:

 

Thanks!so if it is not because of temperature then why after 5 minutes it goes down?
another thing is that I cant even do this after reinstalling windows. I go to the same procedure but it goes down to 1.8.
Where can I download the 7th version?
Thanks

 

See on the the bottom of the profile of UncleWebb :thumbsup:

 

Hi,

I have enabled Start Minimized, Minimize on Close, and Task Bar. With these set and saved, Throttlestop shows in the task bar, but when I minimize or close the main window it still shows up as a minimized window. Before, the minimized window didn't show up at the bottom, only the taskbar icon (by the clock).

This is happening on Win7x64 with both versions 6 and 7 of throttlestop. Is there anything I can do to get it back to where it only shows up in the notification area by the clock, not as a minimized window?

Thanks!!

 

erecker - Have a look in the Options window and make sure Task Bar is not selected. This option seems to work correctly in Windows 7, 8 and 8.1. Let me know if you are still having any problems.

 

TS7b3 blue screens in W10 with i7-3770k, machine check exception 9c. i7TurboGT runs okay though.

 

Thanks for the feedback Dufus. Hopefully Microsoft gets Windows 10 fixed up. haha

I will have to have a look at this and see if there is anything I can change to get ThrottleStop working with Windows 10.
Maybe this is the end of ThrottleStop.

Was the 3770K overclocked? Did you try ThrottleStop on your 4th Gen laptop? Maybe I should try running W10 on my Y510P. I see myself playing musical hard drives to see what I can figure out.

 

IMO it would be sacrilege not to be other than for testing. The laptop W10 runs in a VM, I would not take the risk just yet to run it bare.

EDIT: I needed to post some power figures at defaults, no overclock, and TS7b3 worked with crash!

 

Dufus - I think ThrottleStop is mostly innocent. I installed Windows 10 and the latest beta to a fresh hard drive and I didn't have any ThrottleStop related stability issues.

http://i.imgur.com/vU8rsX1.png

The only problem I had was the usual problem with the System Tray / Notification Area icon. Originally it worked fine. I rebooted and then it wouldn't show up anymore. ThrottleStop would be displayed for maybe 5 seconds at the lower right and then the red icon would just disappear. I used the clean the icon cache trick and then it started working correctly again in Windows 10.

How to Clean the Notification Area Icon Cache in Windows 7 & Windows 8

After the icon cache has been cleaned, I haven't had this problem with recent ThrottleStop versions in Windows 8.1. I will look into this further but perhaps there is only so much I can do with a C++ compiler that was designed to write apps for Windows 98. Might be time for an upgrade to see if that helps.

erecker - If you switch back and forth between ThrottleStop 6 and ThrottleStop 7 beta 3, you will need to run that icon cache cleaner. Give that a try and let me know if your icons and the Task Bar option starts working correctly.

 

Hey! Love your work with ThrottleStop, I've been using it on my C2D for ages and it did miracles to my system's performance.
I recently bought new Clevo notebook with i7 Haswell cpu and I'm going to check soon If I need TS.
If I stop using TS and just turn it off/delete from hdd does it in anyway still exist on my system? I remember that few versions ago I had some problems with correct CPU freq after uninstalling TS.
Thx in advance!

 

i used throttlestop 5.0 on my acer 7738g with windows 7 x64 @ QX9300 without any problems @ multiplier 12.0 vid 1.5

now i installed windows 8.1 x64, when i set the multiplier to 12 the FSB gets down to 210 from 266, so i get standart clock 2500mhz

where is the problem?

 

Wodzian - ThrottleStop is a self contained program. If you unzip the program and drag the folder to somewhere on your hard drive, all you need to do to remove ThorttleStop is to exit the program and delete that folder. The only problem is that ThrottleStop writes information directly to your CPU. Depending on what you have set in ThrottleStop, these changes will be in your CPU until you reboot. If your bios does not fully reset your CPU, you might have to shut your laptop down and you might have to unplug it and remove the battery too. This seemed to be a problem mostly for the laptops with Core 2 Extreme CPUs. Some bios versions were not expecting that a person was going to unlock and change the multiplier so they ignored this register. The registers to control this feature were secret for years until Dufus showed me how a Core 2 Extreme works. For the majority of laptops, shutting down your laptop and starting it up again should be enough to reset the CPU to its default settings after you remove ThrottleStop.

VAG - There was a problem on some laptops where changing the multiplier screwed up the Windows system clock. Different versions of Windows default to different timers internally. If this timer is no longer accurate, the reported bus speed MHz and total MHz will not be accurate. When this timer gets screwed up, some games and other benchmarking programs will also be screwed up. Your best bet is to have a look at this forum.

http://forum.notebookreview.com/asu...-game-timing-problem-g60jx-2.html#post7364805

It shows you how you can change Windows timing to use a fixed counter that should work correctly regardless of your multiplier or FSB speed. Open up a command prompt with Admin privileges in Windows 8.1 and type in this.

bcdedit /set useplatformclock true

Even without this fix, I think the newer versions of CPU-Z should work correctly. Not sure since you didn't post any pictures to show me the problem you are having. If ThrottleStop or CPU-Z are screwed up, fix your timers with the above command. Also try upgrading to ThrottleStop 6 or 7 since I think I tried to fix this problem quite a while ago.

 

here it is

i only looked at throttle stop, cpu-z shows the real clock

https://imagizer.imageshack.us/v2/1012x532q90/540/v6hbxi.jpg

 

I know this used to happen but I cannot remember why. The good news is that your CPU really is overclocked.

Did you try using the bcdedit command to see if this problem is timer related?

If you exit ThrottleStop and restart it, does that change anything? Does clicking on the FSB or BCLK button change anything?

Your original multi was 8.5 and now it is 12.0. For some reason, ThrottleStop is applying this ratio to your bus speed when it reports it which is obviously a mistake.

266.0 X ( 8.5 / 12.0 ) = 210.58

If you do some testing and figure anything out, let me know.

Try running my WinTimerTester tool for about a minute to make sure your Windows clocks are in sync after you overclock. This program should report something very close to 1.000

WinTimerTester 1.1
WinTimerTester_1.1
http://www.sendspace.com/file/xadvhe

I updated to the latest Windows 10 preview edition and ThrottleStop is still working.

http://i.imgur.com/BXw55nm.png

 

Thanks Dufus for taking the time to track that bug down. I will do some testing this weekend and get that fixed up in the next beta.

 

i cant get throttlestop to start when windows boots anymore
even though task scheduler, tried 6.00,and all the 7.00 beta's
have no idea what's changed, the program work great when i start it myself but its a pain to have to remember every bootup

 

Any newer version on the way? I miss the profiles, my settings are not saved well

 

This still works for me in Windows 7, 8 or 10. Are you following the method in the second post of this thread exactly?

http://forum.notebookreview.com/har...es/531329-throttlestop-guide.html#post6865107

ImageShack doesn't want to share the pictures anymore but if you follow this method, it should work. There is a link to some pics for Windows 8 so hopefully you can follow that and get it working.

DackEW - If your profiles are not being saved it is usually because ThrottleStop does not have Read and Write access to the ThrottleStop.INI configuration file. This can happen if you move the ThrottleStop folder from one place to another. Sometimes Windows helps users out by randomly changing these settings.

Find this file in the ThrottleStop folder and right mouse click on it and select Properties. Click on the Security tab and make sure it looks similar to this.

http://i.imgur.com/vG7Qjtq.png

If you are still having problems, can you tell me exactly one thing that is not getting saved correctly. That will make it a lot easier for me to troubleshoot. ThrottleStop has 101 settings and I try to make sure that they are all saved and restored correctly but I won't be too surprised if I missed one or two of them. If all sorts of things are not being saved then it is probably the Security settings that got messed up. You could also try exiting ThrottleStop, delete the ThrottleStop.INI config file and then restart ThrottleStop and it should recreate this config file with the correct Security settings.

 

Hello fellows, I actually come to you from a problem with my desktop. I'm under the impression this utility should work anyways though. (Sorry if I'm wrong.) I'm stuck on iGPU for the foreseeable future, and it's locked itself to base clocks.

Specs are 4670k with the TDP set to 100w or 120w for short turbo. CPU is clocked to 4.2Ghz, iGPU should be at 1250Mhz. Some of my games don't register as "needing" the higher clocks and so drop to 600Mhz and sub-20 fps. I've read the OP but have no earthly idea what to do as I've never used software tweaks, and am fairly new to tweaking as it is. I came here from a similar thread over at [H].

This is the most info I can get from TS. Sorry. :\


If there is any more info I can give you guys let me know.

 

How and use xtu? Xtu can make most adjustments you need. https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProdId=3483

 

hello again unclewebb,

we have the same laptop, Y510p

i just noticed that Throttlestop in unable to stop the throttling when the temperatures exceed 97C, at 97 C the FID throttles to 8
before your program would allow me to play at 100C and it would only throttle to not exceed 100C, so i would still get FID 14-18 at 100C

any idea why this is happening.
i recently deleted version 7 beta 3 of TS and redownloaded the same to see if it fixes the problem. no luck, it persists.
i also double checked the settings to make sure the program is turned on and all the check boxes are appropriately ticked.

what can i do to make it work again.
thank you,
M

 

sonofcrake - No version of ThrottleStop can be used to prevent the CPU from throttling when it is overheating.

There are multiple temperature sensors. If the highest temperature anywhere on the CPU package reaches the thermal throttling temperature, your CPU will throttle. The ThrottleStop Max column is only sampling the core temperature sensors but there are also other temperature sensors on the package that feed temperature data into the thermal throttling control system. The new temperature box to the right of the Power Saver function displays the CPU package temperature for Core i CPUs. The package temperature is the highest temperature reported from any of the temperature sensors. In your example, the highest CPU core temperature is currently 57°C but the package temperature is showing 58°C so one sensor on the chip is reporting slightly higher than your peak core temperature. This is normal.

The Intel specified thermal throttling temperature for your CPU is 100°C. Have a look at your screenshot where it says PROCHOT 99. That means that in the bios, Lenovo decided to lower the thermal throttling temperature so the 4700MQ in your laptop will start to throttle at 99°C instead of 100°C. Unless you were previously running a modified bios, that is how your CPU has always operated in your Y510P.

The other thing to observe is that there is a check mark in the PROCHOT 99 box. Regardless of any reported maximum core temperature, that check mark confirms that a temperature sensor somewhere on your CPU reached the 99°C thermal throttling temperature. Intel included this data in their CPUs because monitoring software is not always fast enough to record the peak core temperature. When a CPU starts throttling, the CPU multiplier and core voltage is being adjusted thousands of times a second. When the CPU reaches the thermal throttling temperature the multiplier starts to go down. The instant the core temperature goes under 99°C, the multiplier starts to go back up. There is so much going on in a CPU when it is thermal throttling that when software comes along once every second to sample the core temperature, it is rarely going to get the exact peak core temperature. It is only reporting the peak core temperature at that instant in time. If you use the ThrottleStop - More Data option, it will sample the temperature sensors more often and it might get lucky and show you a temperature 1 degree higher but that's about it.

Short answer, ThrottleStop confirms your CPU is thermal throttling and there is nothing you can do about that. Your only options are to disassemble your laptop, replace the thermal paste and I have heard that cutting away some plastic that shrouds the fan in this laptop can help reduce your core temperatures. It is clear that Lenovo decided to use a heatsink and fan that are barely adequate for the job. I wish the fan would ramp up in speed some more but I assume the majority of consumers prefer a slow quiet computer compared to a fast but loud computer. Enthusiasts need laptops with better cooling.

Dufus - I finally got around to testing the voltage problem you were having on my 3570K. You are 100% right. Even with a clean INI file, ThrottleStop ignores the extra voltage in MSR 0x194 and zeros that part of the register when it first starts up. Thanks for reporting that problem and I will definitely get that fixed up in the next release.

 

Hello again. I've recently got myself an i7-4790K, along with a high-end aircooling unit that gives me very decent temps. My issue is that whenever I run TS Bench with 8 threads set (or any multithreaded CPU benchmark for that matter), the clock rate is fixed at 4.0GHz as opposed to the stock 4.2GHz. I've enabled a fixed x45 multiplier on all cores without touching voltages on Turbo Ratio Limits as well as the default Intel Power Balance setting of CPU-15/GPU-9 to CPU-20/GPU-4. What am I missing here that could lead to four core loads to downclock to 4.0GHz when temps are well within reasonable levels (never had any throttling so far)?



EDIT: Ok, apparently I'm getting TDP Throttle lighting up for some unknown reason when running TS Bench. How can this be if it's not nearly reaching the stated 88W TDP, being around 60W instead?



EDIT2: When running TS Bench with 4 threads, I still get TDP Throttle (56W recorded) but it does run at 4.2GHz. 2 threads and lower does not trigger TDP Throttle, but shouldn't throttle only occur at/near rated TDP?

 

Tribaljet - When TDP Throttle lights up, that's a sign that you have reached a power limit and your CPU is throttling because of that limit. Have a look at your Turbo Power Limits. The Long term Turbo power limit is set to 45 Watts and the Short term limit is set to 56 Watts. Why are these set so low? Are you running ThrottleStop from a USB stick and those settings came from a different CPU? Those limits are way too low for your CPU.

The default values that Intel recommends is if your CPU has a TDP of 88 Watts then the long term power limit should be set to 88 and the short term limit should be set 25% higher so that would be 110 Watts for your CPU. If you are overclocking, these values are going to have to go higher in order for your CPU to maintain full turbo boost when fully loaded, especially if running something like Prime95 version 28.5. Have a look for these settings in your bios. You might need to update your bios if there is a problem. I would also recommend that after you boot up, before you start ThrottleStop, delete the ThrottleStop.INI configuration file so ThrottleStop can read the current values from your CPU. The PP0 Current Limit looks correct for a desktop board so I am not sure where those low ball power limits came from. They are definitely causing the throttling problem that you are seeing.

Thanks for posting those screenshots. That makes it a lot easier to troubleshoot a problem. Hint, hint for the rest of the people that always forget.

If you were trying to create a low power 45 Watt desktop CPU then you should enable the Clamp option too. This should throttle the crap out of your CPU so it doesn't exceed 45 Watts no matter what software you are running.

 

You're definitely right, unclewebb. I ported my portable ThrottleStop from my i7-2820QM and didn't create a new .ini. After creating a fresh file, things went smoother, although I should note that while general settings were reset, Turbo Ratio Limits, Turbo Power Limits and C State have all kept the previous values, despite me having deleted the .ini. I wonder if this is a bug or what could've made the settings from those menus to stay as opposed to a full wipe alongside profiles and general settings.

I have set some profiles for emulating other CPUs and wasn't aware Clamp was needed, but that'll come in handy for some experiments.

So, after setting long term power limit to 88 and short term limit to 110, I am now exceptionally happy to say I now get full on 4.4GHz on all threads at full load, with 95-100W readings as opposed to the previous 62-65W. Seriously, someone give unclewebb a cookie... actually scratch that, make it a full on jar of cookies for I couldn't be more of a happy camper right now I might tinker with additional clock rates later on, but for now I'll just enjoy unhindered max stock performance while keeping an eye for temps, especially as I'm aiming to have under 80C on full load, but time will tell.

And given screenshots are more often than not requested, might be good to add that to either the OP or signature as to help speed things along.

 

Thanks for the feedback tribaljet and it is good to hear that you got your CPU sorted out. I will look into the INI issues you mentioned.

By default, Intel designed the turbo power limits so if you reached the limit, turbo boost would be disabled and your CPU would be left running at the default multi which is 40 for your i7-4790K. They also included a Clamp option but this feature is rarely used. With Clamp enabled, the CPU will throttle below the default multiplier. I included this option in case any manufacturers were using this trick but it is also handy if you are doing some testing and want to create a low power CPU without having to spend any extra money on one.

 

Sorry about being late, I just got back to this forum.

I can use XTU to overclock the iGPU but not to keep it in the max power state. I'm not sure how I would do that?

 

So I set up throttlestop on my Dell M4400 with a T9600. Win7x64

Turned speed step to off in bios. EIST is unlocked in the program.

Then I set profile one:
Clock Modulation:100
Multiplier:11x
BD Prochot on, C-states on
VID 1.1 set and shown in both boxes.


What I wonder is why does the FID/multi keep fluctuating depending on load. Is this normal. I've tried to run "dual ida" and indeed when I run the ts bench both cores are at 11.x multiplier. When CPU is lower thought the multiplier falls again. I was thinking this was 11x all the time.

In CPU-Z I get completely different info, 1595 mhz and 1.213V Sometimes it jumps to 2.9ghz.

Hw monitor shows both clock and VID as set in throttlestop. Changing the throttlestop settings almost immediately alters stuff here behaving as I thought it would. Clock modulation and multiplier alterations are reflected in the sensor status window. The 11X multiplier holds and the clocks are jumping around 29xx on both cores (slightly different values)

So who is right? Throttlestop readings? HWinfo64 readings? CPU-z? Is dual IDA really on?

For battery I set:
Multiplier 6.0
Power Saver
Disable Turbo (doesn't appear to really work)
Prochot
SLFM
EIST
Cstates.

VID set to 1.0250 but really it goes to .900v in HWinfo and hangs around 800mhz on idle, jumps to 1595 and the voltage setting I set when working and at 100%.

Is this actually going to save me power or just waste power clocking low and taking longer to process any tasks?
