The ThrottleStop Guide

CLU is liquid metal, why does it needs repasting?

 

I heard Mr. Fox saying it needs repasting every 6 months to 1 year for optimal performance.

 

Just be careful and you'll be fine.

People say to re-do it at least once a year to avoid the heatsink corroding from natural degradation.

To Mr. Fox, 1 degree is an improvement, and at the tops of benchmarking it is. So he'd rather keep his stuff freshly pasted.

 

I am not understanding this. How would repasting with the same compound help with corroding? I can see CLU affecting corroding on the heatsink but I dont see how would that affect temperature too much....

 

CLU in itself degrades. People don't want their heatsink to be corroded by it, so they repaste. The new compound hasn't degraded yet, so it lasts longer.

 

This exactly. I have been using CLU on my current laptop (W230SS) and if it is left a long time, it will start to not be liquid anymore and is very hard to clean off.

 

From my perspective, CLU sounds like a make work project?

Is there any TIM anyone here would recommend that can be applied and forgotten? While also being worth disassembling a notebook for?

 

hello there!
having testing in the last few weeks(my turbo boost kicks in now thanks to this thread ), i have a question. Running a bench 1024,4 threads, puts C0 at 100%, which immediatly locks my multiplier at 25. My max is 27, which i am getting if not benching. I have a i5-5200U. Any reason for this? My limit reasons table has been clear, sometimes it shows yellow EDP under "ring", ive seen it on uncore, rarely.

As for undervolting, i´ve been trying to follow dufus advice, and i put it to -50mv on "offset". Should it stay adaptive, or i should put it to static? I´ve been reading the "undervolt guide", it says to use a different software i guess is it ok to use throttle stop to everything, even stress test with bench?

 

From what I read, ICD seems to be one of the best long term TIM available. No personal experience though.

 

Here is a good site for finding out what an Intel CPU is supposed to do.

http://www.cpu-world.com/CPUs/Core_i5/Intel-Core i5-5200U Mobile processor.html

For a 5200U, you get the 27 multiplier and 2700 MHz when 1 core is active. When 2 cores are active, the multiplier drops to 25 so your maximum speed will be 2500 MHz. When these CPUs are lightly loaded, they will constantly be switching between 1 core active and 2 cores active. This is happening hundreds of times per second. This is why the multiplier that ThrottleStop reports is constantly hunting around when lightly loaded. On most processors, the ThrottleStop multiplier data should give you an accurate look at what the CPU is really doing internally. It sounds like your 5200U is running exactly as Intel intended it to run. Lowering the voltage helps reduce power consumption and should help maximize performance. Most laptop users should leave the voltage on Adaptive.

There are hundreds of benchmark programs to choose from. If all you do with your laptop is surf the net and play some games then in my opinion, running demanding tests like Prime95 - Small FFTs for 8 hours is not really necessary. The ThrottleStop TS Bench is an OK bench for quick testing purposes so you can watch how the multiplier responds. It creates some stress and heat without going overboard like Prime95 testing does. To test stability when gaming, I still use the Heaven benchmark. You can also let it loop for a few hours. This benchmark is a very light load on the CPU. To simulate a more demanding game, I just run a thread or two of the TS Bench while the Heaven benchmark is running.
The most important test is to use your computer as you normally would. If it runs fine at default voltage but crashes when under volting then that is a good sign that you have gone too far with the offset voltage you are using. I have heard that some U CPUs can run reliably while using offset voltages up to -100 mV. Have fun testing.

 

As always, thanks for your quick reply. The feature works properly in version 6.00 which I'm very happy to continue using for now.

I currently have an Intel Core 2 Duo Extreme x9000 2.8GHz (45nm) which I understand is quite rare, and seldom do I have reason to invoke SLFM. So, it makes more sense that your efforts focus on newer technology. I'm close to upgrading my machine anyway which I will insist make good use of Throttlestop. Nevertheless, I'm curious what advice you might have to offer when selecting a modern processor/chipset.

 

can i test this? i have an U processor on a well cooled laptop(i never seen my cpu going + ~68ºC, on full load). Seems like a good candidate

 

Hey, I have a Lenovo y50-70.

When I stop Throttle stop and turn it off, my pc still keeps the same cpu speed... How can I revert this?
EDIT: My own mistake

 

My plan is to add a new feature to ThrottleStop that does the exact same thing that PowerCut does. I think I will call it PowerCut.

As soon as it is ready, I will send it your way for some testing. Hopefully in the next day or two. Thanks for your offer. Do you see any PL1 or PL2 throttling when using Limit Reasons?

I didn't realize that the SLFM feature worked correctly once upon a time. It has been a while since I programmed that part of ThrottleStop. That's why it is frustrating when I do not get enough feedback. It is easier to fix problems when you hear about them immediately. I finally have some time to do a little bit of programming so I will have a look to see what has gone wrong with this feature.

 

Will this absolutely interesting feature/program work with 3rd gen cpus? For my part, especially a 3820QM in a HP Elitebook 8570w. Because of the HP bios restrictions I hope to get out of the lack of oc and uv. With the help of PowerCut a constant turboboost should be possible.

greetings

Hi UncleWebb, is there a way to overclock the ENVY 17t K200, product number: K2Z68AV with the 5500U @2.40ghz? If so is there a step by step that would apply to it? Thanks for all the work you do.

 

The new PowerCut feature will only work on the 4th and probably the 5th Gen CPUs. PowerCut will not work on 3rd Gen or 6th Gen Skylake CPUs. ThrottleStop will work on your 3rd Gen CPU but what it can do for you really depends on what the manufacturer decided to lock in the bios. If the bios locks a register, ThrottleStop cannot unlock it. You would likely need a modified bios. The 3rd Gen CPUs do not use the Integrated Voltage Regulator so you cannot use ThrottleStop to undervolt one of these.

@Dominick_7 - As far as I know, you cannot overclock a 5500U but the PowerCut feature might be useful to you. Maybe it can help you run your CPU at 2900 MHz when both cores are active without it throttling down due to the power limits.

http://www.cpu-world.com/CPUs/Core_i7/Intel-Core i7-5500U Mobile processor.html

IntelFreakI5U on OCN claims that he has overclocked his U CPU on a Mac. I will wait for him to post some more details.

http://www.overclock.net/t/1592152/intel-core-i5-4200u-overclock-3-9ghz

 

I have to admit, a permanent turboboost could be an interesting feature.
What would be the inconveniences, like overheating and such ?

 

My limit reasons are kinda changing all the time. Right now, i see PL2 in core, uncore and ring. Usually i see only EDP on uncore/ring. Yellow.

 

Thanks for the reply. Hmm k. Is there a step by step on how to do that? And if you up the voltage and it shuts off will that damage it? Sweet. So if he was able to overclock his via a mac. You think that might have some overlap with the ENVY? I posted a reply so I get an update whenever he's get around to posting the detailed guide.

 

You might have a long wait, never heard of a MacBook Pro coming with an i5-4200U.

 

btw, been looking at your tutorial on .ini file, what i see is not particulary equal to what it is shown, can you check if this settings look fine to you?

 

@unclewebb: can you please tell me, if Throttle Stop works with my i7 3960x on my Clevo P570WM? I'm asking because regardless of what I'm setting (i.e. Multiplier set to 40x) it just runs with Turbo Boost and then throttle slightly down to 3,4Ghz.

Any ideas?

There is a register that ThrottleStop does not have access to that might be blocking your overclock. To access this secondary register, try running MaxMulti that Dufus wrote.

MaxMulti

What are your Turbo Power Limits set to? If these are not set high enough, that can lead to your multiplier reducing over time.

Unfortunately I do not have access to any 6 core hardware for testing purposes. Can you post some screenshots so I can have a look to see if ThrottleStop is working correctly. Can you also run the DufusDump tool and post the log file it creates.

DufusDump
http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/page-416#post-10196838

There is a lot of information in this file that might help Dufus or I solve your problem.

 

He posted the guide by editing the op: http://www.overclock.net/t/1592152/intel-core-i5-4200u-overclock-3-9ghz. What you think?

 

heyo im back, ok so I had two problems when i set throttlestop to startup (used task scheduler). I had to have a 30sec delay for it to turn on during startup(idk why but it solved it). Now my 2nd problem is there anyway for me to minimize it to tray? Its always on my taskbar, any fix?

Nevermind I fixed it too! lmao im blind, i was looking for this option inside "options" maybe a fix in the future for dumb people like me. Sorry guys! great program btw, makes my laptop sound like a jet and perform like a jet! Just kidding, hp is crap and I had to use this because their cpu throttling is out of this world. Last hp laptop for me.

 

Hi all,

currently I'm using ThrottleStop 8.00 b7 to undevolt my mobile Skylake i7 6700HQ under Windows, which works very well so far. Unforunately, I'm working under Linux most of the time where ThrottleStop isn't running at all. Are there any plans to bring ThrottleStop to Linux?

Moreover, due to the fact I really like to undervolt under Linux, it would be great if someone could tell me the MSR Hex to do this. So, in principle I like to undervolt the CPU Core Voltage as well as the Cache Voltage by using an Offset Voltage to both of them.

I already played a lot around in order to find out what ThrottleStop and/or XTU is doing with the MSR register while manipulating Cache and Core Voltage Offset with these tools. I used MaxiMulti, DufusDumb, MSR reader as well as MSR walker to find out any differences between a certain offset voltage and no offset voltage.

Unfortunately, I didn't find any consisty between enabled and disabled Offset voltage in the dumbed MSR registers.
Looks like all these tools didn't print the needed MSR register which will be used to undervolt.

So, my plan is to use the Linux tools rdmsr/wrmsr, put these into a simple boot-script to apply the proper values during boot.

Could someone please give me the proper MSRs for CPU Core and Cache voltage to write to as well as the MSRs to monitor these two values?

Thanks and kind regards,
Kontr-Olli

 

I would love for ThrottleStop to come to Linux, that would be absolutely fantastic. That would be the only way it could possibly be better to me. Otherwise, it's perfect for me!

 

Well, would be really great to bring ThrottleStop to Linux. A command-line tool for scripting purpuse in addition to the GUI would be rather easy to implement in Linux...
Instead of using the winring.dll to adress the MSR register, one could use a linux library....the GUI would need to be brought to GTK or QT....and the additional command-line tool could be used in rc-level autostart scripts, taking a config file into account which was created by the GUI for example...

well, but the magic is behind the MSR registers for each CPU which isn't documented in full detail for public use, which indeed I don't understand. I payed for the intel CPU therefore I also like to know the meaning of each register I can work with....maybe Intel is taking a typical DUMMY user into account, that's why they don't publish all details on the MSR register....

Nevertheless, it depends on unclewebb and it's knowledge about the MSR registers to make a Linux tool reality....I guess he is the only person so far able to deal with most of the "unknown" MSR registers in the latest CPU gen. If he is interessted and willing to share his knowledge one could think about a tool for Linux.

But at the moment I would be already very happy to know the Cache and Core Offset Voltage MSRs to undervolt my CPU under linux with rdmsr/wrmsr command line tools. So, no big deal I guess...

regards,
Kontr-Olli

 

@Dufus
@unclewebb
I'm legitimately confused right now.
Background story: I've used ThrottleStop for a while now and somehow with the help of unlocked BIOS I disabled PPL MSR locks, so I can set Short and Long PPL in TPL tab in ThrottleStop. My laptop is Lenovo y50-70 with i7 4720HQ CPU, with TDP limit of 47W. I've set the limit to 65W, but frankly it didn't work - it was still throttling because of Uncore. So, after undervolting the System Agent I got to this point:

The most interesting thing about this is that roughly a minute after taking this screenshot and rebooting I'm unable to get this to work again :/ The only thing that changed is the battery percentage(it increased because the laptop was connected to AC), and yet it still TDP throttles at 47 Watts, lighting PL2 in red in all 3 rows in Limit Reasons. Is there a logical explanation for this? Btw, I'm definitely willing to test PowerCut, I'm just fed up with my laptop not cooperating

 

EDIT5:
Nah, the Clover BCLK OC isn't real, just like I thought. It just skews system time so it appears to be running faster, but in reality it isn't
---------------------------------------------------
And if we are on the subject on logical explanations:
https://i.imgur.com/MVCbc7p.jpg
I used Clover setting BusSpeedkHz to get some kind of a BCLK OC(???) I've set it to 140 and it seems to yield nice results in Cinebench and Geekbench, but:
How is that possible and can it be implemented into some kind of a windows app?
EDIT:
I can't believe it's BCLK if I can push it to 150 mhz. Clover is open source so maybe someone could look at it and see what it actually sets. Btw, it's the same method one guy used to OC his i5.

First I thought it was just a matter of wrong reporting of the frequency, but Cinebench kinda did its thing faster so I don't really get what's going on here.

 

I cant help being what I am

@Ultrax5
Super CBR15 score. Try this OSX bench, 3 runs at 10000 or 15000 problem size. I'd be interested what it reports.

Read this page

CPU Tuning here

As for power limiting there's a lot of strangeness with the Haswell systems some of which I don't have a clue. I've seen for instance turbo boost act like a non-turbo bin with PL1, that is it doesn't limit unless clamped.

 

Looking forward to PowerCut... I have a lenovo yoga s1 with a 4500U processor which feels great if it not were by the limited "turbo" feature.

 

Not sure why but TS seems to be closing itself after the system resumes from hibernation...

 

Try using sleep mode and see if it still does it then?

 

It seems to be random. I started using a programme called "restart on crash" that will restart TS if it's ever not running

 

that's strange... it crashes when I unplug from AC... edit: sometimes!

6300HQ here

 

I've written what's essentially a TS guide for undervolting + temp profiles here: http://www.ultrabookreview.com/10167-laptop-undervolting-overcloking/

I've done my best to give the most accurate information, but if I missed something then please let me know.

 

Just received a PM from @hdneo



i7-4710HQ unlocked and working with TS. Congrats and welcome to the club.
P.S. Better not let @D2 Ultima see you running more than 70W with a BGA CPU.

 

i could break 4790k @ stock clock with lower TDP.

mobile chip is always better than desktop chip.

 

@hdneo how do you have unlocked multiplier?
I have the bios unlocked but I don't find this option
Thanks in advance

 

i modded bios. old microcode has been installed on int now. there is a hole (bug) @ microcode ver 1 or 2 that multipliers are unlocked on haswell cpus.

 

Ok, and how do you have installed older microcode? Can You help me? I have a lenovo y50-70 4720hq

 

http://donovan6000.blogspot.com/2013/06/insyde-bios-modding-cpu-microcodes.html
This guide worked well for my Y50-70.
Anyway, you will still need to somehow get over the TDP limits, and for me it sometimes works and sometimes doesn't. OR you can use PowerCut when it's released, but that involves waiting

 

follow instruction @ http://donovan6000.blogspot.com/2013/06/insyde-bios-modding-cpu-microcodes.html

backup your bios with universal bios toolkit. your bios must be 6.5 MB size. open with hex editor. find microcode on it and replace with this microcode: https://www.sendspace.com/file/c40ey5
save your bios. flash your bios with sleep BUG (put your notebook on sleep then get up it then use fptw64 -f bios.bin -bios).shutdown your system. now your system ready.
Note: check your new bios size before flashing.

 

Ok, perfect , I do it now.
This microcode is also for 4720hq?
https://www.sendspace.com/file/c40ey5

Thank you very much, regards

 

yes. all haswell cpus (notebook+desktop) support this microcode.

 

Do you have it for broadwell?

 

I cannot sent PMs. I have i7-4600U and I like to test it.

 

this method may not work with broadwell.
this link is a some broadwell microcode. choose old ver .
