The ThrottleStop Guide

Sadly got same problem here.. Need unlocked BIOS for my R4 to solve this but the A13 BIOS hasn't been unlocked by svl7..

 

I thought that the M17x R4 had a board limitation of 67W for the CPU? Any CPU?

 

Unlocked vBIOS is needed to turn off the limitation... Or do something about it... I'm kind of stuck since I don't want to downgrade to A11 and flash unlocked and svl7 can't be bothered to unlock A13 even though people have been asking him for months...

 

Thanks alot, I forgot that I posted here. It has been working very well with this method. Though I still prefer disable Intel Turbo Boost completely and stick to 2.5 ghz as for myself I don't notice much difference in games.

I'm curious about undervolting. I have MS1763 barebone (GT70) with i7 4710MQ. It almost always works below 70 celcius at 2.5 ghz but I can still feel the temperature on the keyboard in 19 celcius ambient temp room. It makes me sick. I wonder if I lower voltage of CPU, can I get rid of it? I don't know if this temp is also contributed by GPU though.

 

put a better paste and let it work at 3.3x4 cores....at least...mine is goind 3.5 but not all the time

 

Thanks for suggestion, there is Thermaltake TG3 which is most expensive paste in my country. Will you recommend it? I used Zalman TG2 in the past but it was difficult to use due to fluidity.

Do you undervolt your CPU by the way? 3.3 ghz sounds great but does its temps close to 90 celcius during load?

 

IC Diamond
Arctic Céramique 2
Gelid GC Extreme
Shin Etsu x23-7921 5

or if copper heatsink and you're willing to be careful as hell
Coollaboratory Liquid Ultra.

 

Is there anyone who has tested out the new Conventional paste "CoolLaboratory Liquid Copper"? http://www.coollaboratory.com/en/products/liquid-copper/

 

It's not as good as Liquid Pro or Ultra

 

It is a standard Conventional paste and can not be compared with Liquid ultra. But I thought more about how quality is relative to IC7 and Gelid extreme. Maybe it could be a good number three after these two.

 

Not that it matters to you anyway

 

Thanks I appreciate your help but sadly none of them are available in my country. Perhaps I could find them in eBay. Which one is you would recommend in those options of thermal pastes? And why should I be careful about using Coollaboratory Liquid Ultra? Does it cause damage to copper heatsinks?

 

Liquid Ultra only damages aluminum heatsinks. Copper is fine for it.
I would quicker recommend Gelid or Arctic Céramique 2 just for ease of application. But ICD is the best out of them if you apply it correctly.

 

throttlestop doesn't seem to have control over the tdp limits.

 

@unclewebb i have an Acer aspire 5742g core i5 3rd gen laptop. There is an overheating problem in it and i saw a website where they said i can cool down laptop using throttlestop. I want to cool down the laptop but i want it to perform sufficiently good as well. I want to know the optimal multiplier value. Please help

 

Read.. http://forum.notebookreview.com/thr...-liquid-ultra-any-tips-before-i-start.741745/

You should apply a new fresh good quality thermal grease if your processor(laptop) is warm as you say. Maybe you're able to reduce the temperature by 10 degrees with a really good thermalgrease and application on your processor and GPU..

 

I have a Lenovo X1 carbon 2nd gen: Win 8.1 64 bit and i74600. Anyone tried Throttle Stop on a similar machine? What I am noticing is that the machine is making clock rate decisions for itself and I would rather make them myself.

 

The Core i7-4600U is a 15 Watt processor. Intel designed these CPUs to throttle and there might not be a lot that any software can do about that. With a limit of only 15 Watts, these CPUs can throttle down into a low TDP state where the multiplier will also get locked down to 8 leaving you with an 800 MHz processor. I have yet to see any laptop manufacturer mention this feature of Intel's low power U processors. The Carbon has a good screen but you might be disappointed with its performance when running any app that puts a sustained load on the CPU and GPU.

 

Thanks for the note in reply. I guess I am not trying to radically overclock the cpu. I just want to override the software that sets the clock speed artificially low. This is a 2.1GZ procecssor. Most times the machine decides to run at 1.97GZ and sometimes slower than that. Just being able to set a default at 2.1GZ would be good. Interstingly, I have had the machine running for several days now at 3.0GZ; I know that if I shut it down and reboot it will default to a lower speed. I have no idea how it "chose" 3 GZ on the last boot up. Will Trottle Stop work on machine to do what I want? I know that this is not a gaming machine....I did not buy it for that.

Are there any issues if I download Throttle Stop? Is the latest version 6.0??? or what is the link for the proper version (for Win 8.1)

 

There have been people reporting this type of behaviour.. It's really random... If I can find the thread, I will link it but it had to do with a Lenovo with i7-4500U..... Try using Throttlestop and setting the multiplier to 30x.. Make sure you keep the processor cool somehow..

 

Just one more question: version 6.0 is that correct? The reason I ask is that it doesn't list Win 8.1 64bit as a compatible os

 

6.00 is the latest full release. 7.00 has an expired beta and Unclewebb doesn't mind us cracking it for functionality.

 

First off, thank you very much for this software and article. I've been having a problem with my Dell E6400 for the longest while which has had me stumped. Whenever I did anything even putting in a DVD or browsing the web with one program open...sometimes no programs i've been getting 100% cpu usage. As a techsavvy person i've been slapped in the face and clueless.....I've cleaned the fan and heatsink, changed the hard drive, changed the memory, reinstalled 3 different versions of Windows 7, clean boot via 'msconfig', ran virus scans/malware/spyware/root kits....i've gone in windows services and disabled: windows update, superfetch, windows media network service, windows media player and anything scvhost.exe related, I downloaded the latest device drivers including the latest bios (A34) and chipset but ABSOLUTELY NOTHING WORKS/WORKED......So I was now obviously convinced that it was a hardware problem maybe a defective CPU or fan/heatsink even a bad motherboard. Was going to throw the thing away (literally) or sell it for peanuts but luckily 2 days ago by chance I stumbled on this blog and THROTTLESTOP....Oh i also stumbled on another program called CPU Z first but that didn't have any effect whatsoever was still getting 100% spikes which rendered my laptop unusable......So far since using throttlestop i've been getting the best performance ever out of my laptop ..no more spikes or lag.....I have a problem though...I have configured it by chance and through basic understanding, I have no idea if i've clicked or selected the right stuff and wouldn't want to be premature and run into problems later..... here are the specs for my laptop: 250gb hdd, 4gb ram, core duo 2.53ghz.....i just want to know which options i should and should not tick in the 'performance profile' of the software and the corret 'set multiplier' and vid because i'm a newb to overclocking/underclocking/undervolting etc

 

So here's a screenshot of my current throttleshop config.....I went into options and experimented with the 'start dual ida' and since then it has automatically untick the 'eist' option with was ticked before and I try to revert but it auto-unticks almost instantly although the 'eist' option is still tickable (not greyed out).......My maximum 'set multiplier' is '10' but as you can see i took it down to '8' and i lowered the vid from 1.2500 to 1.1500 not sure if i'm being counterproductive but i was reading about undervolting and decided to try it ...should it be at the maximum '10?' ....also as you can see I unchecked the 'BD PROCHOT' .....Also I have 'CLOCK MODULATION' checked but 'CHIPSET MODULATION' unchecked because I see you said it is only really necarry to select one or the other however on a lot of youtube videos i've noticed that both are selected by users simultaneously, also which one should I check Clock Modulation or Chipset Modulation or doesn't it matter because my selection was just a guess really... So i basically wanna know if i'm messing my stuff up because i'm really clueless and new to this..thanks

 

JTECHJA - Great to hear that you finally found a way to fix your Dell E6400. Extremely frustrating for users that Dell did not get around to properly fixing the throttling problems this laptop model has as well as many other models that they produced.

As you read, my suggestion is to only check off the type of clock modulation that your laptop uses. I cannot remember off hand but I think the E6400 uses Chipset Clock Modulation. The proper way to test for this is to turn both of them off, go run some very demanding applications like Prime95 and maybe the Heaven 4.0 benchmark or perhaps Furmark at the same time and see what type of clock modulation throttling that ThrottleStop reports on the right hand side. The CMod and Chip columns in the table should always show 2 columns of 100.0. If you see 50.0% or 12.5% then check what column that is in and correct that problem using that ThrottleStop feature. This isn't that hard to test and configure but most users prefer to just check them both off. That's fine. I just prefer to know exactly what the problem is.

EIST (SpeedStep) needs to be enabled for the Set Multiplier and adjustable VID voltage feature to work. Your screenshot shows that you changed the Set Multiplier value to 8 but that change is being ignored because you have EIST disabled. If you have a need to run your CPU at a slower speed, you will need to enable EIST first. Same thing with any VID voltage changes.

The default multiplier for your CPU is 9.5. Your CPU also supports a feature called Intel Dynamic Acceleration (IDA) which allows one core of your CPU to run a little faster. ThrottleStop takes that further and lets you lock both cores at the IDA multiplier. (Dual IDA). Thanks to Dufus for showing me that trick. Your Dual IDA multiplier is 10.0 and your screenshot shows that you have discovered that feature. Disabling EIST locks both cores so they both use the 10.0 multiplier. Not a huge difference in performance but I like any increase in performance that is free. I think checking off Start Dual IDA in the Options window will automatically put your CPU in Dual IDA mode when you start ThrottleStop. You should also be able to do a right mouse click on an open area of ThrottleStop and select the Dual IDA menu.

1.15 volts is reasonable for the speed that your CPU is running at. You might be able to go a little lower but you have to do lots of testing. If you go too low, your CPU will become unstable and your computer will probably crash ( BSOD blue screen). Usually you will be able to reboot after this happens so you can continue testing with a little more voltage.

Edit - If you are interested, there was a huge paper written up called Throttlegate that explains the issues in the E6500. As far as I remember, the E6400 was not this bad but it sounds very similar to what you have endured.

I own a ThinkPad Yoga with an i7 -4600u. I've had all sorts of issues with it being sluggish since purchasing it a year ago. Thanks to @unclewebb, @Dufus, and the other posters in this thread, I was able to determine the root cause and partially work around the issues.

The symptoms I experienced were:

• CPU capped at lowest multipler (800MHz) when display off (e.g., when laptop lid closed)
• CPU capped at lowest multiplier randomly
  • For months at a time, this seemed to be caused by plugging into a certain AC adapter
  • Sometimes this would happen when I plugged into a Lenovo OneLink dock
  • Only fix was to reboot
• CPU capped at 18x multiplier during sustained load

I haven't found any way to work around the 18x multiplier cap, but I have been able to stop the CPU from dropping to 800MHz by setting the TDP level to 2 and then setting the lock bit. I had to set this via ThrottleStop and RW Everything.

Hopefully this info is of use to someone else with a i7-XXXXu CPU.

 

Welcome back, @unclewebb. I just read your post in overclock forums about Haswell adaptive verses static voltage - a very nice read. I have always used adaptive, because I really didn't understand the pros of static, but I am now moving towards a static approach. I am running into a problem, however. While identifying the default voltage at any particular clock multiplier is pretty easy (just use Throttlestop), I have not found a good way to identify the current default voltage for the ring/cache voltage. I was hoping you might have some suggestions.

Thanks much.

 

My preference for adaptive or static voltage changes depending on the situation. When overclocking a desktop Haswell CPU, I like the keep it simple approach. Keep increasing the static voltage and multiplier until you reach the point where you have to increase the voltage an insane amount to go further. At this point, back the multi off 1 step and do some stress testing. If you want to save some power, enable the C States and you are done.

I don't know of any software or any way to read the current ring/cache voltage from the CPU. If you wanted to run this at a static voltage, you would have to try different voltages to see what's stable. Intel XTU does not give me the option to use a Static cache voltage on my 4700MQ. It is set to Adaptive by default.

 

Thanks for the quick reply, @unclewebb. I am guessing that the ring/cache voltage is close to the core voltage, so I guess I'll start from there. Hmmm... Does the ring voltage also follow the C states or does it always stay at a set voltage?

 

Without having any software to measure it, I am not sure what the cache voltage does at idle when the C States are enabled. You can use a static voltage for the core and still run adaptive voltage on the cache if you want to.

There are 6 separate voltages that I know of in the Haswell CPUs that can be controlled individually and set to either adaptive or static. If you do some Google searching, you should be able to find a picture of the bios settings for a desktop Haswell board to get an idea about what normal voltages are for these.

 

Here is an example of the layout of volts adjustments of Hotwell 4670K-modell during the adjustment ..
Then you have an idea of vring volts versus Vcore.

 

You could do with a Clevo and a prema BIOS. At least the PxxxSM-A models before they're phased out. See if someone will donate one to you or lend you one? Because I can set cache voltage to static (I have on default usually; I just adjusted the slider so it would let me set adaptive/static).

HOTWELL. LOL!

 

Thanks, @unclewebb and @Papusan. From the voltage chart, it appears that the ring voltage does not "float" with the multiplier and remains at a set voltage. I suspected that behavior from my test results, but it is good that is confirmed. Of course, as you noted, @unclewebb, there isn't currently a way to determine what happens at an idle C state. Currently, it appears that my i4790k is stable at a ring voltage of 1.07.

Thanks again!

 

Can i undervolting Haswell i7-4900mq/4910mq with ThrottleStop 6 or ThrottleStop 7?

What can i use alternative software for undervolting? I use only software, no Bios.

 

Sergeant - Use Intel XTU to undervolt your Haswell CPU.

D2 Ultiima - I can change my Processor Cache Voltage from Static to Adaptive with some special software I have but for some reason, Intel XTU has decided to disable that option. I like Intel XTU but it seems to cause issues when resuming from Stand By with the occasional crash and then it forgets my settings. It is providing me with some motivation to come out of retirement.

Oh you're such a tease!

 

If you do decide to come out of retirement, I am sure you'll find a lot of support in this forum. I would be happy to help beta-test. I am running an i7 4790K, so I can test the unlocked settings.

 

Oh man, how sad to have that verified. I posted quite a bit ago with the exact same problem with my i5 and its tdp of 15 watts. I get 1.2 ghz from my 2.7 turbo speed when I have any intensive video/games being played. There is nothing we can do huh? I am a bit frustrated that its actually something they do on purpose, seems kinda shady to me. Its not really what its advertised to be..

 

Hey peeps. Need some advice on this program.
Ive been trying to help my little brother with his computer which have a BayTrail computer and he really wants som better performance out of the N2840 chip.
However there are some weird stuff I dont understand.

1. VID is 4.4375V according to the program lol. Obviously wrong. Should I let that stand unedited or will that voltage be applied if I enable "Set multiplier"? I have no idea what the native voltage for BayTrail really is.

2. Multipliers are 83.34MHz according to the program, so the N2840 runs at 2580MHz in total. 2580/83.34 = 31x I reckon? Anyone have any idea if N2840/BayTrail overclock nicely? I mean the CPU fan hardly comes on and its just a 7.5W CPU, so I think there are some rooms for it.
The PSU is 33W btw.




Thanks

 

Unfortunately, ThrottleStop 7.00 does not support Bay Trail processors. If you are brave and click on the Turn On button, your Bay Trail will probably crash.

The good news is that I was working on ThrottleStop 8.00 today and it finally reports the correct multiplier for Bay Trail CPUs. Probably within the next week, full Bay Trail support should be done.

The bad news is that Bay Trail CPUs are low power slugs. TS 7 reports the bus speed correctly at ~83.33 MHz but TS 7 does not report the maximum multiplier correctly. These CPUs use Turbo Boost, similar to a Core i CPU. The MHz they run at is not a good indication of their actual performance. For many tasks, they have to run at nearly twice the MHz to try and equal the performance of Core i technology.

The maximum multiplier is locked so you will not be able to overclock an Atom at all. I have a 4 core Bay Trail CPU that I have been playing with and it is able to use the maximum turbo multiplier continuously on all 4 cores when stress testing. This means that even if the turbo power limits were unlocked, raising them is not going to increase performance any. The Atom is what it is. It is a tablet CPU.

For performance, I am pretty sure an 8 year old Core 2 Duo will outperform a similar Atom in almost every task, except power consumption.

My thoughts exactly. Intel knows that the average Joe consumer buys computers based on MHz. The bigger number the better.

 

Well thats too bad then. Was hoping you could raise TDP and atleast do some small changes with the multipliers with the program. I know, Intel decides what you can do with the CPUs with the use of firmware.
Guess my brother just got to get used to it then. For surfing etc it works fine, but he wants to play some terraria. Even overclocking the IGP would be helpful. Intel XTU doesnt seem to work with BayTrail at all.

 

Will you be releasing 8.0 fully Unclewebb? 7.0 was not officially released (well was a beta) and we have had to use cracked versions of it..

 

Were can i find cracked Throttlestop 7.0 or how can i crack it myself. Because i cant use my laptop without it.

 

No idea about this either, that's why was wondering if unclewebb could release 8.0 once he's added the baytrail stuff in...

 

Yes. I wouldn't still be working on ThrottleStop if I didn't plan to release it. After years of randomly adding features, TS had become a confusing mess. To add support for a wider range of CPUs, I had to gut the beast and go through the code line by line. It was very time consuming but I am almost done. I finished multiplier and VID adjustment for Bay Trail yesterday, support for 6 and 8 core CPUs is almost done, and full 4th Gen FIVR voltage control just needs to be tested. It was a challenge trying to fully support the vast majority of Intel CPUs released in the last 9 years with one simple, light weight tool. After all the recent changes, I need to release a fresh beta for 2015 but I also need user feedback.

Cloudfire - For a semi fair comparison, here is 2 cores of Bay Trail vs a Core 2 Duo T8100.

http://i.imgur.com/D41UQ6R.png

It took 61.5 seconds for 2 Bay Trail cores at 1866 MHz to complete wPrime 32M.

http://i.imgur.com/lTcMI4y.png

A 7 year old Core 2 Duo can do the same calculation in 38.8 seconds and the T8100 was nothing special back then.

Back on topic. The screenshot shows that Dual IDA works correctly in TS8 and I added an adjustable Windows Timer Resolution feature which can help cure some stuttering issues.



TS8 beta will be out shortly. TS8 Final will depend on if users are willing to help out with testing.

 

Thanks much, @unclewebb. I will be happy to help test TS8. I am sure others will too.

 

Thank you @unclewebb ... Can't wait for this.. Hopefully something can be doine about the power throttling I have with my 3940XM in the Alienware M17x R4 after power usage goes over 60W... I have to flash an unlocked BIOS to disable some Intel setting however hopefully throttlestop can do something about this

 

Starting from a clean slate? Awesome. Looking forward to it!

 

Not exactly. Same old ThrottleStop. I just did a massive clean up of the program. This has allowed me to add support for a lot more of Intel's current and future processors, especially the Xeons. It was brought to my attention that some servers are having throttling issues due to BD PROCHOT so I thought allowing users to disable that might make me a few new friends.

The first TS8 beta just went out to some testers with a 6 and an 8 core CPU. TS8 might just work on a board with dual hyper threaded 8 core Xeons and perhaps it will work on a 15 core Xeon E7. Fun times!

TomJGX - If your bios has locked the power register in the CPU, there is nothing that ThrottleStop can do to help you with that problem. Your only option is to flash the bios to remove this lock.
