The ThrottleStop Guide

Hi unclewebb, Throttlestop works perfect for me: I'm able to overclock X9100 in Windows XP. However I'm using only Linux. Could you point me out which MSR unlocks multiplier? Using 0x199 MSR I could only downclock CPU.

 

mdncr - Try using RW Everything or my MSR Tool.

When you are in Windows, unlock and adjust your X9100 multiplier higher with ThrottleStop and keep an eye on MSR 0x194. It shouldn't be too hard to figure out. Dufus was the brains behind this feature so thank him for sharing it with me.

Question - Does anyone need a version of ThrottleStop for their 6 core CPU or for their dual CPU server? Julien at Ranch Computing was having some major problems getting their servers to run at full speed. A problem with BD PROCHOT was cutting his CPU speed in half so I wrote him a special testing version of ThrottleStop. Here was his reply.

With a positive review like that, it looks like supporting the 6 core CPUs is on the things to do list.

I don't own any 6 core CPUs so if you are interested in doing some testing, let me know.

King of Interns - Thanks for the positive feedback. Great to see that you are still rocking your 920XM. Those 45nm CPUs were built like tanks. ThrottleStop has always been the 920XM CPUs best friend.

 

I know some Clevo P570WM owners that would be tickled to have a version of ThrottleStop that works with their 4930K and 4960X CPUs.

 

Yes, I for one would love to have that tool for my P570WM

 

Dufus and unclewebb thanks a lot! MSR 0x194 do the job.

 

Hi. I have X9100 cpu. Could you tell me how can I just unlock multiplier and exit program keeping maximum multipllier for standart windows powe scheme? For example when I run throttlestop and set multiplier to 19 it shows correct fixed speed. When I exit ts it resets to usual maximum multiplier. But when I restart windows Windows can speed up cpu up to 19 x. How do just unlock max multiplier and keep this maximum and let windows use standard power scheme?

 

[

Hi,Unclewebb,I recently purchased the dell venue 11 pro model 7310 with I5 CPU,and I run

some tests,this I5 CPU will disable turbo booost and goes down to 0.6 GHz when the CPU

above 60C.and can't even watch the online video smoothly,I use the lastest version of

ThrottleStop,and no matter I do,it doesn't work.I would like to use ThrottleStop to

raise the throttling temperature a bit higher most likely 70 or 80 C temporarily .is

that possible?

 

wdeh - Here are the specs for a Core i5-4300Y.

ARK | Intel® Core™ i5-4300Y Processor (3M Cache, up to 2.30 GHz)

These CPUs have a Max TDP of 11.5 Watts but the SDP is only 6 Watts. Long term, that is not enough power to run the CPU and Intel GPU at their full rated speed. It's not enough power to do much of anything. I wish ThrottleStop could do more with these low power devices but I think Intel locked them down to prevent software from doing that. I do not think there will ever be any software that is going to turn a 6 Watt CPU into anything more than what it is, a 6 Watt CPU.

The throttling you are seeing is usually based on power consumption, not core temperature. The temperature will be somewhere around 60C when this happens but the limit is usually power consumption. The multiplier and MHz reported by CPU-Z does not appear to be very accurate when a CPU starts to rapidly throttle like this. You can trust the MHz that ThrottleStop is reporting.

Can you post a screen shot of the TPL - Turbo Power Limits window? Have you tried using the Intel Power Balance feature? If you direct more of the power budget to the GPU then you might get a little better overall performance. I expect that most stuff in this window is locked by the bios and even if it wasn't locked, it is not going to make a significant difference.

I will never buy one of these low power CPUs with my own money for development purposes. If this device does not perform as you expected, send it back to Dell.

eugene2878 - Is the "Do Not Reset FID / VID on Exit" option checked? See if that works for you. It has been a long time since I have looked at this code so I can not remember what it does with an unlocked Core 2 Extreme CPU. I think your unlocked multiplier should be maintained when that option is checked. After you exit ThrottleStop and re boot or go into Stand By or Hibernate mode, what happens depends on the bios. Some laptops might reset the maximum multiplier and some might not. I just leave ThrottleStop running. Then I have a very good idea what the multiplier is going to be. ThrottleStop is pretty light on CPU and memory resources so leaving it running should not be overly stressful on your CPU.

 

Thank you for your reply,I don't know much about the hardware,although this CPU is a low power processor,but it's enough to do my work.And what bothers me is the CPU throttling,As I said above I did some tests,and found out CPU temp above 60C when the throttle happened,and The multiplier suddenly drop to the lowest and then raise up,and then drop again,it makes this tablet can't play online video smoothly when the multplier change so frequently.But if I find a big fan to blow behind the tablet and keep it cool below 60C,the multplier can keep stable at 20(high-performance power plan),and everything is ok,I can open 3 or 4 online video at the same time,and all play very smoothly.This is what I am trying to do with TS and see if there is any way to adjust the throttling tempereture above 60C.

 

Some of my thoughts on Haswell

I've actually noticed that Haswell has brought back the Current Draw limitation. This is the real culprit behind the throttling on this generation. It hasn't really been implemented since Sandy Bridge where the firmware even locked the ability to alter this despite being able to freely set the TDP. Ivy bridge chips actually had the current draw limitation default set to 95A most of the time on most machines thus these chips were pretty much only limited by their cooling.

For Haswell, I've played around with the i7-4700MQ and I noticed that around 75A current limit is needed for unimpeded 3.2Ghz on all cores while 95A is required for 3.4Ghz on all cores. Be warned though, load Prime95 Temps on the W230SS (which has the option to force 100% fan speed) hovers at around 70 degrees (2.8ghz 55A stock setting), 80 degrees (3.2Ghz 75A) and 95+ (3.4ghz 95A).

Why the rapid increase in temperature? this is squarely the fault of the IVR, VRMs very rapidly increase in temperature when forced to operate beyond the rated spec. Combined with their tiny thermal transfer area and you can understand where Haswell's infamous temperatures come from (on the desktop, its basically not entirely the fault of the Heat Spreader).

I honestly don't think the situation will improve with broadwell until Intel either:
- Eliminates the IVR (highly unlikely because this is the secret to Haswell's better power draw + idle characteristics)
- More VRM phases (also unlikely as this increases Idle power draw)
- More efficient VRMs (most likely due to 14nm lithography but don't expect miracles)

 

Thank you for you reply. Yes. I have this option checked but for some reason it does not work for me. When I exit with this option it resets to original multiplier. And when I restart I do not need to run TS and my cpu is unlocked upto maximum multiplier and use speedstep.
Original bios does not support unlocking of multiplier, so it was patched by Nando few years ago. I would not mind to leave throttlestop running in the tray. I just would prefer idea to have highest multiplier unlocked for my cpu and use Intel speed step. So laptop would use maximum speed when needed jumping from lowest to highest like in original windows power scheme.

 

I'm eager to try undervolting my NUC D54250 that has a 4250U CPU.
I use my NUC as a download pc and control it through RDP, so no input devices or screen attached.

My question is this: If I experiment with how low I can go on the voltage and it freezes, will a reset disable the undervolt setting or will it be enabled again, and freeze the system again, upon running TS?

 

hi, here the TPL for i5 Y-series (level 2 cant be selected)


btw, because the annoying 6 watt SDP (i wish it can be hacked and removed away lol), down-volt the CPU and GPU actually increase the performance.

with -70mw on CPU and -50mw on GPU, the fps increase 10fps in Left 4 Dead 2.
With -70mw GPU, the fps goes up 15 fps but the graphic driver will crash in a few minutes.

so, for anybody with the annoying Intel Y series CPU, try down-volt it as far as you can. The boost in performance is delicious

 

Hello,

I have a Toshiba Qosmio x775-3DV80. I7-2670M with an nVidia GTX 560M. Having consistent throttling issues after about 7 months of purchase. Any game throttles. Today, after remounting the heatsink with some Artic Silver 5, still having problems. Pattern kind of shows it may be the GPU throttling at around 70C even though I've heard they're capable of more than 100C before thermal throttling. CPU Temps were peaking at 93C before remounting--which lead me to believe it was the CPU at first. Temps are generally cooler after remounting... but I'm still in the curing phase. The fan is also clean.

It also appears Toshiba has locked mostly everything down in the bios. I can't even control the speed of my fan... I have the newest bios, newest nVidia drivers, and newest Toshiba drivers. ThrottleStop settings and log attached. I can make a clearer log if this one is confusing. The battery was removed before the second thermal throttling occurred.

Thanks for reading.

Edit: Added another log. Not so consistent with GPU: View attachment 2014-06-263333.txt

 

orangpelupa - Thanks for the screen shot. With your CPU, the TDP Level Control is useless. The Long Term Power is locked to 6 Watts and the Clamp option is also enabled which makes sure this CPU is going to remain tied to a tree. If you could find someone to modify a bios for you and unlock that register, it would do this CPU a world of good. Have you played with the Intel Power Balance feature yet? Setting all of the power budget to the GPU and zero for the CPU can help out when gaming or trying to game I should say. I was playing around with voltage control tonight. Adding some more voltage control options to ThrottleStop is about all I can do to help out with the low power U and Y series CPUs.

 

@unclewebb
thanks,more voltage control wil be a nice option for me and those with intel Y.
About bios, unfornately there's not a huge community of Intel Y series bios modders, unlike with those in AMD Desktop board bios moddng

yeah, i also have tried fiddling with power balance but nowadays games need CPU at 0.9 Ghz minimum to make it playable (left 4dead2, portal2, watchdogs need 1GHz+) otherwise the fps will get even much lower due to cpu bottleneck.

So what i have done to be able to play Watch Dogs on Intel Y i5 is the reverse, i put 15 to CPU and 5 to GPU in Power Balance. Then run the game in 640x360 pixels upscale tp 1080p.
Yes the game looks crap but it works

thanks unclewebb

 

orangpelupa - When you have the time can you run CPU-Z and create a text report and then copy and paste the info to Pastebin.com - #1 paste tool since 2002! and post a link here. There are a few registers that I am curious about.

With the Long term limit locked and clamped to 6W, it probably won't make any difference, but have you tried locking your TDP to Level 0?

 

here the pastebin of txt rport for intel i5 Y intel i5 Y - Pastebin.com
sorry i have not try to "lock" the TDP level. will try later

thaks

 

Hi, this software is absolutely amazing.
I have Dell Inspiron 7537, I5-4200u, GT 750M DDR5, 768p screen.
When CPU use more then 15W for 30s, frequency goes down from 2.3 to 1.8-1.9.
I did set static voltage 0.8V(default is 0.92V ) for 2x2.3GHz and worked stable i all games, including Crysis 3 and Watch Dogs but still had throttling issues in OCCT and PCSX2 Emu with MTVU on.
Set the intel power balance CPU to 31, GPU to 0, and goodbye throttling :hi2:

 

i did notice the temp improvements when disabling turbo while gaming. i also lower my offset voltage to -60
what else have you tried?

 

Interesting. I may have to try this out on my Sony Vaio Pro, because GPU throttles like crazy, making some games unplayable because it's fine then FPS dips to an unacceptable level, then back up to decent, then back down. The GPU is showing a fluctuation in speed when I track it.

 

Hello unclewebb,
I have Intel XTU installed in my Alienware 18. Please, I have two questions:

1) If I install throttlestop with XTU already in, may I have some incompatibility?
2) Comparing Intel XTU and throttlestop which one gives better result regarding OC?

Hello!
I have a sony vaio fit multiflip. After 10 minutes with HDMI attached mu CPU frequency fall to 0.58ghz. Even if i set CPU max frequency to 100% and high performance mode. How can i use ThrottleStop to avoid this problem?
Thank you



EDIT:
I don't know why, but if i disable BD PROCHOT, even with turned off TS, the CPU works perfectly.

 

could i have some help to get my computer to its max here are my specs http://i.imgur.com/FXmYPS2.png http://i.imgur.com/0N5mlLI.pngal so some step by step help would be great im new to throttle stop

 

Unclewebb, beta 2 works wonders on my 4700mq. Managed to make it max out where XTU just froze all the time.
Thank you again, +rep.

 

Your screen shot shows your CPU running at 798 MHz. If another monitoring program or Windows says 0.58 GHz, it is wrong. I am glad to hear that your CPU is working better with BD PROCHOT disabled. When you use ThrottleStop to disable this, it turns this feature off within the CPU until you reboot. If you use Hibernate or Stand By mode, BD PROCHOT will usually get turned back on by the bios so you might need to run ThrottleStop again after you resume from Hibernate or Sleep. No need to run it if you don't need it running 24/7.

With BD PROCHOT disabled, your computer will still throttle if the CPU ever gets too hot and reaches the thermal throttling temperature. Turning BD PROCHOT off prevents other items on your motherboard or your GPU from throttling your CPU when it probably does not need to be throttled. Keep an eye on your temperatures when this is disabled. Your U CPU is designed by Intel to be a low power CPU. Some laptop manufacturers lock these CPUs in the bios so there is not too much you can do with ThrottleStop. Other manufacturers leave a few things open so you can use ThrottleStop and improve your performance a little or a lot if you get lucky.

dmt_2000 - A Core i3 CPU does not use Intel Turbo Boost so unless your laptop has a throttling problem, ThrottleStop will not be able to make your CPU run faster. To check for throttling you would need to turn on the Log File option while you are gaming or doing something stressful with your laptop. A log file should show a high multiplier, at or near the maximum which is 17 for your CPU and the 2 different types of Clock Modulation should be showing a constant 100.0%. If that's OK then you do not need ThrottleStop.

sangemaru - Thanks for the feedback. My 4700MQ likes ThrottleStop 7 too.

rbatts - ThrottleStop and XTU have some features that are similar and some features that are not available in the other program. Try both programs and use whatever program gives you the best results. At the moment XTU has more voltage control options for the 4th Gen CPUs so if you need that, use XTU. You can run both programs at the same time but you have to be careful when doing this and you have to understand that the CPU only has 1 set of registers. If both of these programs are writing information to the same registers trying to control your CPU then the results will be unpredictable. XTU assumes that it is the one and only program accessing these registers. ThrottleStop puts more effort into maintaining whatever you ask it to do. If you are running both programs at the same time, if ThrottleStop detects that another program has changed something, it generally tries to change that register back to whatever you set in ThrottleStop.

I have lots of plans for more features but it is too nice outside these days to be inside programming. Pray for rain!!

 

Yeah, disabling BD PROCHOT is a really great thing. I am able to do it in the BIOS (unlocked version) but most laptop owners do not have access to this. That is, of course, only true for those that are not smart enough to use ThrottleStop.

This product is truly amazing and I truly appreciate having it. I hope that support for hex-core desktop CPUs works out. If I end up buying a P570WM with 4930K I am going to be wanting to use ThrottleStop with that beast as I do my Alienware monsters.

Thanks for all you do for us, unclewebb. Without ThrottleStop (and HWiNFO64 - thanks to Martin also) being a PC enthusiast would not be nearly as great.

Actually, you're going to want to use both. First use XTU to disable the turbo lock that keeps the Haswell CPUs from working correctly. Once you disable that with XTU the improvement in performance will be immediate. It won't be great, but what's not to love about a 1.0GHz speed improvement with one mouse click and a reboot, right? Not sure why Alienware enabled that in the BIOS, but it pretty much ruins the performance... to say that stock performance is horrible would be an understatement. The nice thing is, XTU will kill that problem real quick.

Use XTU to find out what OC be suits your needs. Figure out what voltage and power settings you like the most. Saving your settings to an XTU profile, then stop using it. It's too inconvenient to use all the time... ThrottleStop is so much easier. Use ThrottleStop to implement those setting and run as a Windows Task during logon. You'll never need to fart around with XTU again unless you decide to do more tweak for higher performance.

 

Can you elaborate on that turbo lock? Where do I find the setting?

Thanks in advance!

And how do you get it to stick on reboot?

 

First I would like to thank uncleweb and Mr. Fox by ever so detailed replies that help us to improve performance.
Mr Fox, I think I understood exactly when and for what use XTU and ThrottleStop.
I have a question: every time when I find out with XTU a stable OC setting or do any change, I do need to reboot to apply those settings? And after that, do I need to set XTU to run on Windows logon for everything works properly? For instance, I’m using HWiNFO64 to improve fans (BIOS A08) and it is working like a charm. But for that HWiNFO64 needs to run on every Windows logon and I still have to open it and minimize to task bar for the fan tables setup I did start working.

Look in this screen shot. I have a red box drawn around it. Once disabled, it disappears at reboot and stays disabled. In order to get the multiplier values to stick after the first reboot you may need to change one multiplier value by one click, click apply, set it back where you want it, click apply.

No, just use XTU to figure out the settings that work best, then plug those in with ThrottleStop once you know them. You can set ThrottleStop to run as a scheduled Task during logon and it will do it perfectly for you every time. The alternative of manually setting things after every logon with XTU is terribly inconvenient. The beauty of ThrottleStop is ease of use and having 4 CPU clock profiles that you can switch between on-the-fly using key combos. I have HWiNFO64 running at Windows Startup as well. The custom fan tables usually takes over on their own. Once in a while I have to click on the little fan icon to open the fan control window (the one with the sliders) before my custom fan profiles actually kick in. This seems to be something with the EC Support being enabled causing a conflict for the laptop rather than a problem with HWiNFO64. I find that having the EC Sensor enabled on the Alienware 18 causes some problems, but with that disabled (box unchecked) it works fine.

 

I have disabled Package Turbo Power Lock and then apply and reboot. Now this option is not available any more in XTU. Is that correct??

 

Uncleweb... Have you ever considered adding additional profiles? I'd selfishly love a 5th or 6th

 

I cannot seem to get throttlestop to minimize to the system tray with throttlestop 7.0b2. In either a bootcamp setup or otherwise. Task scheduler will also no longer start the program. Also when I manually start it, it still refuses to minimize to the tray.

-Solved with clearing notification tray cache

 

Hi Uncle,

Just asking whether throttlestop support 4210u processor
I had try both 6.0 and the beta version and would like to report that the voltage control is nonadjustable at all, while I'm able to control the clock multiplier but it seem not working as the clock speed don't go up

 

HI Dj,

I have Acer Aspire e15 with i5-4210u, which is very similar to your 4200u
May I know which version of throttlestop you using? I'm unable to set the voltage and cant seem to find the intel power balance option too

 

Hi Guys!

I have an Acer Aspire V5-573G with i5-4200u. I am also interested in undervolting the CPU.
Would be cool if you have some tips.
Kind Regards!

 

tgary - Can you post a screenshot of ThrottleStop 7.00 beta 2? The voltage adjustment features ended up in the TRL window. The same register is used to set the turbo overclock and the adjustable voltages so these features are together there. I have no idea if adjustable voltage for the low power U CPUs is supported by the CPU. I think it is. ThrottleStop 6.00 does not have this feature.



To undervolt the CPU I would set ThrottleStop to use offset voltage and then move the slider until it says about -50 mV. That is usually a good place to start.

The Intel Power Balance option is at the bottom of the TPL window.

 

Hi,
I have now undervolted my i5-4200U in my Acer Aspire V5-573G with the Intel XTU.
It runs stable with dynamic CPU offset voltage -80.
And Intel Graphics voltage -90.

But i can't undervolt the Nvidia GT 750M because that is locked...

 

(Repost from y510p Thread Feel free to delete this post if you consider this redundant or the one in the Thread)

Y510p Laptop - i7 4700MQ

I've been running 36T on my throttlestop, Doing Digital Painting and stuff on PS CC Kinda weird though but I made some tinkering and downed it to 34T.
(Highest temp is 70 C or so)
Now I can't seem to bring it up back to 36T

FYI XTU is set for max 36 Multipliers on both Processor and Core.

Weirdest thing is that the Clockrate does GO OVER 3.4, I hardly think this is a hardware issue since no Problems has been arising. Hope this is more of a Throttlestop bug.


PS: Solved It, Re-installed Throttlestop Or so to speak redownloaded it Fixed the Problem im curious to what caused it to act like that though.

 

unclewebb : that it is a screenshot with setting for you y510p?(I have a Y510p and I am a little non-tech person, so I want to apply a safe settings)...

 

Kaeru_p - If you are ever having problems with ThrottleStop, instead of downloading it, just exit the program and delete the ThrottleStop.ini file. This file contains all of ThrottleStop's settings. This is a stand alone program which means there are no additional settings hiding in the registry. Delete the IN file and next time you start up ThrottleStop, it will start up clean and it will automatically create a new INI file for you.

It sounds like you set the Turbo Ratio Limits to a maximum of 34. If you do this, the adjuster on the main ThrottleStop screen will not be able to go higher than 34T. Set your 1 Core Active Turbo Limit back to 36, click on OK and then you will be able to adjust the Set Multiplier value back up to its maximum which is 36T on the Core i7-4700MQ. I wouldn't really consider this to be a ThrottleStop bug. You just need to play with the program some more so you get to know how the program works as well as how a 4700MQ works.

If anyone is having a problem, take the time to upload a couple of screen shots to somewhere like imgur: the simple image sharer so I can have a look at how you have the program setup. If I can see some screen shots and / or some log file data, it makes it a lot easier to figure out what is going on with your CPU.

pigulici - Yes, that screen shot is from the 4700MQ in my Y510P. To be honest, if you are a non-tech person, you probably shouldn't be adjusting the voltage going to your CPU. This is considered to be the deep end of the pool so to speak.

Every CPU is unique and what works for my CPU might not work very well for your CPU. Many years ago when I was playing with Windows XP and a Core 2 Duo, I ended up going too low on the voltage and nuked my install of XP. I had to reinstall everything so I tend to be more cautious when lowering the voltage now.

 

@unclewebb Actually the Core Multiplier is set to 36 on one core it seemed to have reoccurred again, only happened since yesterday. Curiously enough.

The problem is TS multiplier cant get past 34T. XTU is already set to max 36.

 

Hey unclewebb I am running throttlestop 4.10 with my 920xm.
Are there any new features in later versions that might come in handy? Any reason to update?

Cheers KoI.

ps; I am pushing 28x-29x across all cores with an OV completely stable in games. 920xm rock on!

 

As I said before, you need to post some pictures of exactly how you have ThrottleStop setup including the TRL window. When you are using XTU and ThrottleStop at the same time, both programs are writing information to the same registers within your CPU. ThrottleStop usually takes precedence so some of your settings in XTU will be ignored. XTU will also not report your CPU correctly while you are using ThrottleStop. Next time the Set Multiplier in ThrottleStop is locked to a maximum of 34T, make sure that you have opened the TRL wiindow and you have selected Overclock and you have increased the multiplier in this window to 36. This value limits the Set Multiplier value on the main screen.

King of Interns - If your 920XM is rocking with a 28 or 29 multiplier then why bother upgrading ThrottleStop. I like the new version better. I think it is more efficient but a lot of the newer features are for the newer Core i CPUs. Your first gen Core i does not need these features. The latest version also works well with Optimus but I don't think you are using that either.

 

I have Core i7-4712 on my Schenker W230SS/XMG P304. It really clocks down on battery, all the way to 1.4ghz when all cores are stressed. But I can live with that.

iGPU clocks down to 400MHz on battery and that's too low. Aero feels sluggish sometimes, even old games doesn't run any more.

Is there anything I can do iGPU clock on battery use? On AC it's overclocked 1.25GHz.

 

Using ThrottleStop 7.00 Beta 2 for i5-4200U.

To play with PP0, I set the PP0 Power Limit to 10 and since the option did not seem to work, I tried to lock it.

Since then, there is no way to unlock the PP0 Power Limit again.

Rebooted. Shut down and wait and then Restarted. Reset Bios. Changed CPU Power setting in Bios.

None of them worked. It stays locked at 10.

A similar option, TDP Level Control, can be unlocked when I Shut down and wait and then Restart. PP0 Power Limit stays locked.

Is there any option any way to unlock it again?




UPDATE:

My laptop is ATIV BOOK 9 PLUS. i5-4200U.

I discharged the battery and unplugged the laptop from power source overnight. [DID NOT WORK]
Opened up the laptop, and removed the battery. [DID NOT WORK]
Removed the battery and also removed the CMOS battery... Confirmed that the BIOS was reset. [DID NOT WORK]

So I guess a lesson learned here. Don't ever check "Lock" and press "Apply" for PP0 as you have no way to unlock it.
You will be stuck with whatever PP0 value you set and have to live with it.

I would love to hear feedback / solution to this as I am out of tactics.

 

anybody got surface pro 3 with core i3 Y ?

please add the throttlestop screenshot for TPL. According to anandtech benchmark, core i3 Y on Surface Pro 3 is almost 2x faster than Core i5 Y on my vaio tap 11

Anyone know how restrictive are the HP Elitebook 840 G1, Acer TravelMate TMP645-MG-6429, and Dell Latitude E6440 laptops with the CPU settings?

The first two laptops both use the U-series 15W TDP CPUs, and the Dell laptop uses the M-series 37W TDP CPU.

 

loptimistk - Did you delete the ThrottleStop.INI file after you locked the PP0 power limit? ThrottleStop does not make any changes to your bios. It writes all changes to the INI configuration file. Exit ThrottleStop, delete that file, reboot and you are usually back to the default bios settings. If you went into the bios and changed a CPU Power Setting while the CPU had this Lock bit set, it might be possible that the bios also saved the status of the Lock bit at the same time. I have never heard of anyone with this issue before so make sure you delete the INI file and let me know if it makes any difference.

Loney111111 - I prefer the 37W CPUs to the UM CPUs. More flexible.
