The ThrottleStop Guide

I managed to replaced my microcode 1c to 1 but now my lan is not working because the mac address is FF:FF:FF:FF:FF:FF. I think I messed something up during flashing. I'm using AFUWIN to flash my bios. Found out that I also lost my notebook serial number, uuid, etc. Restoring backup from old bios does not fix it. Notebook is a Asus G751JT with AMI bios. I tried some tools to put the serial number back (AMIDEDOS) but I have no idea how to fix the mac address and UUID. It was mention somewhere that I need to use FD44editor. But that doesnt want to read my bios file. Can you help? =/

 

it seems you replace something more. so find your bios recovery procedure. it may be like this:
hold ctrl + home and power on the laptop with hooked usb 2 with the official rom from asus website renamed to g751jt.bin

 

I have already done that. Still no lan.. I have reset cmos by removing battery and everything but still no lan. Tried flashing older version of bios, no go.

Is there anyone with the same G751JT laptop that would be kind enough to dump their bios and give it to me? Thanks.

 

In effect, Intel has corrected the bug in the new revision with Crystal Well because it changes the CPUID and the version of microcode.


Bad luck for owners Crystal Well, great job anyway. Thank you very much for this great program.

I've done all steps in the readme file, also when enabling Power-Cut the CPU was idle...

 

That is strange. On my i7-4600U I can run it with 37 multiplier. The standard is 33 1 core 30 2 cores, but if I want to I can set both cores to whatever I want in the range to 37. The only problem is that it needs more voltage.

I prefer to run at stock undervolted so I can get better battery life.
Without modifying the voltage it is stable with the following settings:
1 Core Active - 36
2 Cores Active - 34
The other strange thing is that It cannot hit the short term TDP limit (25W) on stock multiplier (30). In order to get to that limit I must run it with multiplier 32 (both Cores). On single core it cannot hit 15W until 36 multiplier.
Unfortunately the cooling on my laptop (Lenovo T440s) is not adequate enough, so with steady TDP > 23W it starts to overheat, PROCHOT starts doing its job to throttle the CPU and that renders PowerCut useless.

 

@hdneo powercut and other things in throttlestop with the microcode ver 01 doesn't work. I have modded and updated The bios with microcode ver 02 and powercut, ecc. work! You Can try it!

 

Yes,it works great. thanks a lot @unclewebb and @Dufus.

 

Just got it working. Thanks!!!

Have a look at the FIVR screenshot that @wiFFy posted for his 4500U.

http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/page-429#post-10213313

His CPU reports +0 for Turbo Overclocking. Your 4600U supports overclocking so the maximum multiplier can be increased by +4 bins. The 4500U is not overclockable. I do not know of any publicly available documentation from Intel that shows this but the info that ThrottleStop reads directly from the processor is usually correct. This is a good reason to buy the 4600U over the 4500U. The difference in price is probably next to nothing.

My Lenovo Y510P is also limited by the cooling system. Barely adequate cooling solutions seems to be the norm from many manufacturers.

@jack34 - Thanks for posting some more details. Haswell has a CPUID of 0x306C3 so it was developed a long time before Crystal Well.

 

Well, if you runt it like it is intended to be running there are no issues and it seems adequate. The problem comes if you try to push it above its limits. Do you know if there is a way to set voltages for multipliers above the standard? Because the max voltage the CPU sets is at 33, at 34,35,36,37 there is no change above it. I know I can set it static to some value, but I was thinking if there is a way do to it step by step?

 

I actually got powercut working after two reboots. Now ThrottleStop reports Package Power under 2w. Before that it reported the actual number. I didn't change any settings in the meantime, so no ideas what was wrong with it before.The yellow blinking in Limit reasons stopped after that. It stays completely black while under load.

I'm not sure if this has something to do with powercut, but my profiles in Throttlestop stopped working at the same time powercut started working. For example if I change from profile 1(multiplier 30) to profile 4 (multiplier 9), it doesn't change the multiplier. If I manually change the multiplier using the arrow-buttons, it sets the multiplier correctly.


-EDIT:Are the profiles working normally for everyone else, who flipped the powercut-switch on?
-EDIT2: Thanks for this release, unclewebb. I forgot to say it before. I didn't manage to really do anything with it, but it got my overclocking juices flowing pretty hard. Last processor that I overclocked was a Intel Core 2 Duo E4300. A relatively cheap 1800MHz processor running at 32xxMHz. That was almost a decade ago. I'm feeling a bit like a dinosaur who just woke up.

 

@wiFFy - On U CPUs, if the Set Multiplier feature is not working correctly, try adjusting the Non Turbo Ratio. By default, my 4700MQ and many other 47 Watt CPUs have this set to 0. Set Multiplier works on my daughter's 3rd Gen U but I have not played with any of the 4th or 5th Gen U laptops. Next time I use her computer, I will try to see what the trick was to get this to work reliably. My best advice for U CPUs is to disable everything and run them as fast as possible, especially now with PowerCut. No need to save power when plugged in and you should avoid using PowerCut on battery power.

PowerCut exploits a bug in Intel CPUs. Knowing that, I guess it is not too surprising that it works a little differently depending on the CPU model.

My first Core i overclocking experience was my E6400. Going from 2133 MHz to 3640 MHz on air, Prime stable, was quite a feat. Sure the air was winter air in my garage but Prime stable is Prime stable. I also had an E4400 that overclocked similar to your E4300. I am still using the same motherboard but with a QX9650 now. That continues to be the computer I use to program and compile ThrottleStop on. Hard to believe my ancient tools are still useful in the modern Core i / Windows 10 era.

@DeXa - If you want the voltage to adjust to the multiplier then you are forced to use Adaptive voltage instead of Static (Fixed) voltage. I have never experimented with voltages when going beyond the default maximum multiplier.

 

I just noticed ThrottleStop is at version 8.10, so it's no longer a Beta?

 

@unclewebb

I submitted ThrottleStop to www.majorgeeks.com since I am an assistant editor there

It will be reviewed and probably posted tomorrow to increase its popularity

 

@unclewebb

My submission was approved. ThrottleStop now hosted on Major Geeks:

hello guys,
i got a lenovo y50-70 (CPU:4720 HQ) with an in-built battery which u can not remove it while for example u wanna play a game.

so does this "PowerCut" feature do what i wanna do ???


another question is, i changed few items like VCCIN cpu input voltage from deafult, now i wanna make EVERYTHING as it was before, how should i do that ?


thx in advance

 

and how to know POWERCUT feature is working properly ??????

 

ThrottleStop is an infinite beta. Kind of like Windows 10 and all the Windows before that. Version 8.10 solves a few long time bugs such as the SLFM bug for Core 2 mobile processors. It took me over a year to hear about that one. Hopefully it is fixed but it might be another year before I find out. Such is the state of freeware software these days. Not enough people taking the time to report and follow up on bugs. I think the new PowerCut feature could be significant to many laptop owners but so far I have not seen any benchmark scores that show this. I like the latest beta so I set the expiry data for 6+ months. Hopefully I get some feedback by then. Thanks for sharing TS with Major Geeks. There are still a lot of users that have never heard about ThrottleStop.

What specific problem are you trying to solve? ThrottleStop is a tool. It can help out with many problems but like a knife, if you do not know what end to hold on to, it can cause a lot of problems. Some Lenovo laptops like my Y510P have some very specific throttling problems that can be totally solved by using ThrottleStop. During some situations, this can improve CPU performance by up to +50%. If you are new to ThrottleStop, take some time to learn about this program before using PowerCut.

After you have played around with ThrottleStop, if you find that it is not the tool for you, exit ThrottleStop, delete the ThrottleStop folder, do a full reboot and your computer should be back to its default settings. You can then use HWiNFO to confirm that all of your voltages, etc. are back to normal.

 

first off, i wanna thank u sir for putting such great amount of time into developing such a software.
i do read the whole TS Guide.
i just explained my problem in my previous post but i'm gonna say it again.
my y50-70 laptop has an internal (built-in) battery which it can not get removed. so when i wanna play a game i want to be on AC power instead of battery in order to maximize my laptop performance.
so i was asking does this "powerCut" feature cut the battery outta the system thus i can use pure AC power from the adapter?
i want my battery be totally outta harm due to temp or over-use or ...

also can we make the GPU throttle problem fix by this software too ?

would u pls kindly state those problems and the solution since we're sharing same brand

thx a lot in advance

 

Hi Throttlestop,
thank u for ur Hard work on this Application! i Hope u will Receive a fair amout of donations for it.

I just Found this Tool and have 2 Things To Mention.

On the Guide Page some Screenshots will not be Shown. Im not sure if that is an local problem with my browser.. It's makes reading the parts a bit theoretical.

The next thing is about my cpu for which I'm actually using throttle stop.
the 5th gen mcx13 broad well CPUs are locked to 65w tdp.
Intel and the motherboard fracturer are giving like zero attention to it.
The bios implementation of that 5th gen support is very bugged. The TDP wall settings are just like fake.
U can't go over 65w by using most bios settings. The only way is that Intel xtu overclocking software which is a bit clunky.
It would be great if ur tool would be able to unlock that tdp wall like that xtu tool.

 

http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-4600U+@+2.10GHz the last baseline is mine ( CPU Marks 4922). I am not using PowerCut though, only undervolted.

 

@iAchilles - The PowerCut feature has absolutely nothing to do with your battery. ThrottleStop and PowerCut can cause permanent damage to a laptop battery so you should not be using this program. My Y510P and your Y50-70 are two different laptops and may have completely different throttling problems. If your laptop has a throttling problem, post what the problem is.

You are welcome and you are correct that the pictures in the guide need to be hosted on a different site. ImageShack went to a paid format so all of the pictures went bye bye. I will get them updated someday if I ever find them.

The PowerCut feature might let you go well beyond the 65 Watt TDP limit. I do not own a Broadwell CPU so you or someone else with one of these will have to do some testing and post your results. Why not post some pictures of ThrottleStop's various windows like the FIVR and TPL windows? I cannot fix or make suggestions when I cannot see the problem.

 

@unclewebb
i will get TDP throttle under full load and i read in ur guide that u said if throttle happens ur CMod and Chip percentage should drop, but i will not see a drop in CMod and Chip instead i can see FID drop due to that TDP throttle. so why CMod and Chip show 100% ?

and which one of Clock Modulation and Chipset Clock Modulation should be checked below the setting section?

thanks

 

There are many different ways to throttle a CPU. Chipset Clock Modulation and Clock Modulation are two ways. If your laptop does not use either method then there is no need to check off either of these options in ThrottleStop.

Did you try enabling PowerCut? This is still an experimental feature but it might help with the throttling that you are seeing. Run ThrottleStop with the Log File option checked. Before you use PowerCut, do some gaming and get some data of how your CPU runs. After that, exit the game, make sure your CPU is idle and then enable PowerCut. Run another log file to see if there is any difference in CPU performance. I added data similar to the data in Limit Reasons to the log file a while ago. Not sure if it works because no one has posted a log file yet.

Edit - You can Copy and Paste log file data to www.pastebin.com and then post a link here so I can have a look.

 

ok i tried PowerCut feature, and TDP throttle disapeared while i up the multiplier and with powerCut feature enabled, i could get higher FID!
but now i can not see the accurate package power, and i dont know how much power consumption is approriate for my adapter or laptop power?

and how much should i set the VCCIN voltage? i set as 1.75v as u wrote in ur readme file.

PS. there are many yellow items in LIMIT REASONS (not red though). even i click on the title, they will get disapeared but the will apear after few moment, mostly PL1, PL2, EDP,... in yellow.
what does that mean?

thx

 

Improved CPU performance is the purpose of ThrottleStop. Lenovo has produced some laptop models that do not let the CPU run at its full Intel rated speed while gaming. The CPU in my Lenovo Y510P deliberately throttles soon after the Nvidia GPU is active. Lenovo never advertised this feature before I bought this laptop so I have chosen to use ThrottleStop to disable this feature. My laptop is no longer under warranty so if it blows up, that is my problem. I will have to fix it myself or replace it. If you cannot afford to replace your laptop at your expense then you should not be using ThrottleStop to disable any throttling methods that it uses. ThrottleStop is for users that are fed up and are willing to take full responsibility for any damage that it might cause.

When Limit Reasons shows a box in red, that means throttling is taking place right NOW. When throttling is over, the red box will turn to yellow. The yellow box is a record that some throttling has taken place. Even if there was some throttling for only a millisecond, Limit Reasons will show a record of that by displaying a yellow box. If you run a ThrottleStop log file while gaming, you should have a better record of how long the throttling lasted for.

Every CPU is different so there is no manual you can read to decide how much voltage is appropriate. If you do not use enough VCCIN voltage, your computer will become unstable and it will crash. If you use too much VCCIN voltage, your CPU will run hotter than it needs to and long term, you might burn out your CPU. My computer has a socket for the CPU so if it ever fails, I can remove it, head to EBay and buy a new one. Most laptops these days are produced with CPUs that are soldered onto the main board. The 4720 HQ in your laptop is soldered. If you burn out one of these you are going to have an expensive repair because you will need to replace the entire motherboard. If you cannot afford to do that then do not adjust VCCIN and do not use PowerCut.

 

UncleWebb, thank you for your brilliant program which has saved my Yoga 3 11 from self-throttling to 0.49G despite motherboard replacement - I think this means that the Yoga 3 11 has a BIOS problem (rather than a Windows 10 problem), do you agree? I'd like to pass your insights on to Lenovo who seem to have interest but little knowledge into this.

Anyway I would like to make a donation to support your efforts, how do I do that?

 

I am not familiar with the Yoga 3 11 and its specific throttling problems. In my Lenovo Y510P, the throttling is deliberate. The Y510P throttles to reduce power consumption and heat when the Nvidia GPU is active. An updated bios was never released to fix this problem because to Lenovo, this throttling is not a problem. It is by design. The front line staff on the phones read from a script and may not fully understand what is going on but I am quite sure the engineers have a clear understanding of these issues.

Thanks for your offer to donate but the "d" word is a dirty word on NBR. How about pay it forward and buy someone that needs something to eat a sandwich. Tell 'em, compliments of unclewebb!

Edit - Here is a review of the Yoga 3 11.

http://www.notebookcheck.net/Lenovo-Yoga-3-11-Convertible-Review.143751.0.html

They noticed the poor performance in their benchmarks compared to the competition.

 

right, thx for the warning. i put the VCCIN at 1.75v and it showed locked and after testing throttling problem was gone.
now how to get it back to default ????? since i removed the TS folder and even restart my laptop, after re-extracting TS, still TS shows that VCCIN is locked at 1.75v !

and how to figure out what is my laptop default VCCIN exactly ?

 

Just an FYI, the sendspace link in the first post keeps on getting being falsely identified as containing a trojan on one of my PCs and Defender kept deleting it.

 

Defender might not like SendSpace but my friends in China are glad I use that site. Over there, many legit sites like Google Drive are blocked.

Can you try the Major Geeks download link?

http://www.majorgeeks.com/files/details/throttlestop.html

They added their url to the download folder but other than that, it looks the same. Some day I will make sure each individual file in their download is identical to what I uploaded. At the moment, I am working on adding more thorough control of the Package C State IRL registers. Almost done.

This practice is not exclusive to Lenovo, DellAlienware also they used since the Alienware R2 (2015). I'm very disappointed with the replacement equipment (Alienware R2) because it is not up a high-end notebook to play, throttle most of the time even the simplest tasks. Although on paper this CPU should run seamlessly with four cores at 3800 Mhz it does not because throttle to 3300 Mhz. Fortunately exists this great software ThrottleStop that helped me with a significant reduction of voltage the CPU can run at 3600 Mhz. However, I can not help that when I play that the CPU thottles to 2800 Mhz after a few minutes.
I've tried everything, update bios, undervolt the CPU to -70 mV and Cache CPU to 50 Vm, manage the fans whit Hwinfo, down the clocks CPU, update Vbios....the result is always the same.
Dellalienware has introduced deliberately that throttle and also if you seek help with technical support they tell you that the functioning is normal.
Thanks to you great software I can get a better perfomence.
1. Stock



2. Wiht TS 8:



3. With throttle in BF4

 

@unclewebb is there another way to make PL1 and PL2 throttle stop, execpt using PowerCut feature?

 

@unclewebb thanks a ton for the new throttlestop! With PowerCut I am able to fully load my 4510u without throttling on both cores at 2.8GHz, before PowerCut throttling occured and lowered the cores to 2GHz, a huge difference!
One question about the VCCIN voltage, I have set it to 1.75 as you said, but I can enable PowerCut even with 1.45V Do you happen to know the default VCCIN for Haswell U processors? Is 1.75 too much or should I set it lower and watch for instability? BTW the temps are no different between default, 1.45 and 1.75

 

Prettypls hellllp @unclewebb

I have a Clevo p370sm-a with 4810mq.
I have tried everything and I´m at my wits end..
I can stress the CPU for ages with WPrime for example and it stays on the designated clock but when I´m gaming the multiplier drops to x28 every once and a while.
I have tried static voltage and dynamic voltage, C-States off and on, always the same. It never throttles, no thermal, current or power.
If you could find time to check my settings if there is anything I could do I would truly appreciate it!

edit: the weirdest thing happened.. I tried to run firestrike and for some reason GPUs videoclock didn´t boost and stayed at 700ish. But the CPU clock didn´t drop! What is happening? Do I need another power brick? I have two 980ms. I restarted the machine and GPUs were normal and CPU dropped to x28 occasionaly..

 

Wow that review's really interesting! One of the reply's says:
"Bjoern
Re: Lenovo Yoga 3 11 Convertible Review
« Antwort #4 am: August 13, 2015, 00:48:37 »
I just went ahead and removed the ... Intel DPFT driver.
After that my clock speed throttling behaved normally. The thermal throttling still works since it's managed by the CPU by itself. Maybe worth a shot."

Could the defective code be in the DFPT driver, and does Throttlestop override it? Any downside to removing it? I'd hate to brick the thing!

Thank you so much, I'll be paying that sandwich forward!

 

@iAchilles - The PowerCut feature is the only way I know to get rid of some throttling.

@billgs - I do not know of any way to read the default VCCIN from a Haswell processor. The 1.75 V number is off the top of my head. Some CPUs can run with significantly less VCCIN. My 4700MQ seems happier at 1.80 V than 1.75 V. If you can run your CPU reliably at a VCCIN setting of 1.45 V then go for it. Thanks for the 4510U feedback. I had a feeling that U CPUs were going to benefit nicely from PowerCut.

@wikileaker - Can you run with the ThrottleStop Log File option checked so I can see what the multiplier is doing. I like to look at numbers more than graphs. Upload your data to www.pastebin.com

Your CPU should not be dropping down to 2.8 GHz. That is the default speed so that is a sign that Turbo Boost is being disabled. Not sure why. It might be starving for power. Have you tried TS 8.10 yet? The new PowerCut feature might be useful for your problem.

@Jonty2 - I do not have the DPTF driver installed on my laptop and it has been running fine for the last couple of years. I have seen a few users removing it and I have yet to hear of anyone reinstalling it after they remove it. I do not know enough about DPTF but from the sounds of it, it has throttling written all over it.

"Cool platforms" are easily obtained if you throttle the CPU to a crawl. That's not for me.

 

Thanks for the reply!
Here is a link to log file when running firestrike. http://pastebin.com/CvPxfQX6
It is with the static power x39 settings I like to use because with adaptive voltage the CPU gets hotter..

Yes I changed to the new version and tried with the powercut turned on. It might have helped a bit but it still lowers the clocks.

I got curious about the fact that multiplier didn´t drop when the GPU clock was downgraded. I underclocked the GPUs video clock and memory by 200Mhz and the CPU clock speed dropped only once! So it actually might be starving for power. Do you think lowering the GPUs voltage would help?

 

@unclewebb thanks for the swift response. Since I do not have much experience with throttlIing think this the best place to start learning (this and the awesome thread on Haswell TDP throttling by Dufus in this forum). 2 more observations and a quick question regarding the last version:
-Every time I boot the laptop and throttlestop loads, when I need to open the limit reasons program, throttlestop prompts me to show it where the program is in the hard drive. This did not happen in the previous versions.
-At some point PoweCut was deactivated between some restarts. I dont know if it was random or due to the fact that Windows Defender quarantined throttlestop and I had to restore it. Will keep you posted about this one.
Question: Now that the CPU is unclogged, I can run the TSbench nicely and without throttling at all. However, observing the limit reason program, I am seeing all three EDP nodes lighting up more or less constantly with every single action I do (opening a web page, scrolling, even during typing this message). The strange thing, at least for me, is that nothing lights up during TSbench or other stress tests. Why is that? I am attaching 3 screenshots showing my main profile in TS.
Whatever new trick or option you want to try dont hesitate to tell me, I recall you do not have a 4th gen Haswell U, so from now on my cpu is at your service!
Thanks in advance!

The multi is running smooth at 39.00 and then at 22:27:50 it drops but it immediately recovers. The Set Multiplier feature watches the register that controls the multiplier. If it sees that it has dropped, it immediately puts it back to the desired value. Not sure why but I kind of think this is what is going on with your CPU. My Y510P does the same thing. When the going gets tough, it disables Turbo Boost by changing this register to the default multiplier.

There are two options to improve this. Originally I added a feature so you could get ThrottleStop to check this register more often. That helped the cause but then I decided to try a second method that is more efficient.

Try setting the Non Turbo Ratio to 1. On my laptop, this completely fixed the throttling. There was no need to check the Set Multiplier option any more which saved some CPU cycles for more important things. By setting the Non Turbo Ratio to 1, that basically tells the CPU to ignore the Set Multiplier register. When your laptop writes 28 to that register to try and reduce the multiplier, hopefully it will ignore that request and continue on at full speed.

 

I did not make any recent changes to the code that controls where Limit Reasons is. How did you install the latest version? Did you copy and paste ThrottleStop.exe to your old folder? Did you create a new folder? If you run ThrottleStop in one folder and then you move the folder somewhere else on your hard drive, Windows can quietly change the file permissions on the ThrottleStop.INI configuration file. After it does this, ThrottleStop will not operate properly because it will not be able to write configuration data to the .INI file.

Have a look in ThrottleStop.INI for this line.

LRFileName=C:\Program Files (x86)\ThrottleStop\LR0101.exe

That tells ThrottleStop where the Limit Reasons program is. For testing purposes, I deleted that line from the INI file and then started up ThrottleStop. I had no problems with the Limit Reasons button automatically finding the Limit Reasons program. After ThrottleStop exited, that line in the configuration file was back in the ThrottleStop.INI file. When using Windows 10, you can manually edit this file but you will need Admin privileges. My trick it to use the Windows + X key combo, then select the A key to open up an Admin command prompt. After that I type in Notepad, open that and navigate to the ThrottleStop.INI file so I can edit it without Windows giving me any grief. There is probably a simpler way but that works for me.

It is up to the bios to reset the PowerCut feature. On my laptop, this happens every time I use stand by mode. After that, when I resume, I have to enable PowerCut again manually. Part of the problem might be Windows or your bios. If the bios does not properly reset the CPU then PowerCut might be left enabled after you reboot. It is not supposed to be but some manufacturers do not always follow the guidelines. I am sure that some engineer never thought that user software would be pulling this stunt.

If your CPU is not throttling then does it really matter what Limit Reasons is saying? Not really. When PowerCut is enabled, the CPU is likely in a very confused state of mind. Good. Try running a ThrottleStop log file and have a look at what the multiplier is doing. Does it show any throttling?

I do not think you need any new tricks. The tricks in TS 8.10 seem to be maximizing performance for you.

Edit - One thing I forgot to mention is that you can usually drop your CPU Cache voltage down a similar amount to your CPU Core voltage. This helps reduce power consumption and heat. You can also try dropping the Intel GPU voltage down too. I drop the GPU down less than the CPU.

 

I shall try to make some input with PowerCut.

I have tested it a couple of times and it successfully changes my power readings. The effects seem to last one or two restarts tops. In order to fully eliminate its effects, I have to restart and shutdown.

I have noticed that if I enable PowerCut and then restart, there are different options available via software like intel XTU. Basically, I have less options available post-restart.

On random notes from my own experience so far: I can't nearly undervolt the processor cache, sometimes only like -20mv only. My CPU is stable at -45mv. This is with 38/37/36/36 multipliers.

My limits right now are current limiting throttling. I haven't been able to modify much but I only throttle to 3.4ghz via current limiting throttling.

 

Installing the latest throttlestop from the sendspace in the OP gives me a virus warning here:
Win32/Varpes.M!plock. A false positive?

 

i don't think powercut feature is working on my envy 15 with 4712hq. is there any thing i should do after enabling the feature?

 

Did you enable it while idle and with VCCIN about 1.70 as in the readme instructions?

Spoiler: Instructions here:

How to Enable PowerCut on 4th and 5th Generation Core i CPUs.
-------------------------------------------------------------
- with laptop plugged in and running on AC power, press the FIVR button to open the Turbo FIVR Control window.
- change the VCCIN CPU input voltage from Default to a fixed value. (~1.75 V)
- check PowerCut and agree with the warning message.
- with CPU idle and power consumption low, push Apply. PowerCut should now be reported as Enabled.
- if PowerCut is Enabled, power consumption reporting will no longer be accurate.
- this can help eliminate throttling based on power consumption. (PL1 & PL2)
- another big thank you for Dufus at NBR.

 

working now. still can't maintain solid 3.5ghz though

thank you!

 

Didn`t help.. :/ It does drop a little less with the powercut and non turbo ratio set to 1. Firestrike score went up 200ish to 13998. But it just grates my nerves that it doesn´t stay where its supposed to be! grrrr

 

I think the 4712HQ has a maximum multiplier of 33 when not overclocking and when overclocking, it is 35. The 35 multiplier is only available when a single core is active. Without a bios mod, you might be at the wall.

@dreassica - Unfortunately, some antivirus programs do not like innovative software that hacks away and manipulates Intel CPUs. If you go to www.virustotal.com, you will probably see that the vast majority of antivirus programs are fine with ThrottleStop. Not a single user in this forum has ever reported an actual virus because they used ThrottleStop. Ever. No one's bank account has been cleaned out, other than my account and that is only because I buy too much hardware for testing purposes that I really do not need. Skylake incoming.

@ryzeki - Thanks for the feedback. How long ThrottleStop - PowerCut lasts really depends on the bios. In theory, 101 things should be reset each time you reboot but some manufacturers do not seem to bother resetting everything. If anyone is having problems and needs to absolutely disable PowerCut or their VCCIN setting, I would recommend shutting down, unplugging your laptop and pulling the battery. That should do it.

 

is there a problem if i used powercut feature on battery?

 

The only problem is that your laptop might catch on fire.

When a Core i7 and an Nvidia GPU are significantly loaded, power consumption can overwhelm pretty much any laptop battery. Manufacturers build in throttling when on battery power for a reason. Running at full speed and load even once when on battery power might significantly degrade your battery so I do not recommend doing this. Keep the fire extinguisher handy before running Prime95 or Furmark or both.
