ThrottleStop - Performance Adjustment Tool for Core 2 / Core i CPUs

[unclewebb]

When ThrottleStop is minimized to the system tray, the performance difference is minimal. If you're bored, can you post some benchmark scores with and without TS minimized to the System Tray. I'm just curious.

If you don't want ThrottleStop running, eating up CPU cycles, you can use the ExitTime=5 INI option and the program will automatically exit 5 seconds after it gets your CPU setup. Also try playing with the setting, "Do Not Reset FID/VID on Exit" in the Options window so your CPU is set up however you like it when TS exits. Make sure you are using the Windows high performance profile.

If that box is not checked, it will write the highest multiplier to the multiplier request register when it exits. If that box is checked, it doesn't touch that register so whatever information that was last sent to that register is maintained. On my E8400 that I used to run at 8.0 x 500 MHz, it was important to have that feature checked or else when TS exited, it would write the default 9.0 multiplier to that register and a BSOD was soon to follow when the CPU tried to run at 4500 MHz (9.0 x 500 MHz) instead of 4000 MHz.

After playing with it a little more, it seems my loss of performance is not from TS running. I loose performance when I change the multiplier. I can change it to 9.5 ormore and my benches are showing less performance. Weirder than that is when I try it back to default 9 I never get back to the performance level I was before I used TS to adjust the multi.

Example: if I boot up, and run IBT I'll get ~40gigaflops, if I then run TS (default nothing tweaked yet) I get 40gigaflops. If I tweak the multi lets say 10 I get 38gigaflops. If I then set the multi back to 9, I'll get 36 gigaflops.

I'm going to try cinebench next and see if I get the same behavior.

EDIT: Ok loss of performance is only with IBT memory fragmentation?. Cinbench shows a massive improvement going from multi x9 to x10

One user with an Alienware M17x-R1 noticed a hit to memory bandwidth when increasing the multiplier higher than the default value. His laptop uses the Nvidia mobile chipset.

Something like that might be happening to you. I have an Intel chipset on my desktop board that I use for testing and I've never seen this issue.

This is a sweet app for using with my throttling 3830tg. I can run a 20x multi all day long w/o overheating, and it performs MUCH better than the 12x multi that it otherwise ends up at. All I've done is just check the 'set multiplier' checkbox, select multi to 20x and turn TS on ... is there something more sophisticated I can do here so that I don't have to turn on TS to game, then turn it off manually when I'm done so it won't run at 20x when browsing and such? I find myself forgetting to turn it off, so it'd be cool if there was a way to 'set/forget' with this application

Also ... on the first page you mentioned voltage control ... is that still 'in the works' at all w/this app, or is it not possible to mess with VID's from Windows on these chips?

Probably thought of this already, but you know what would make this app REALLY incredible is if you could choose an 'undervolt' setting that would apply across all c-states. I've a strong feeling these i5 2410 chips might well be overvolted quite a bit more than they actually need (much like a lot of Fermi's will run at much lower VID than the one they come with stock) ... if the app allowed you to universally downvolt by like .05V-.2V in .05V increments (or something along those lines) I've a feeling a lot of our overheating issues could be solved w/o such large compromises in multi's (i.e. power that we friggin paid for )

In any case, thanks again for the great app ... it's keeping me from returning this lappie that I otherwise love (it's gaming capability is quite amazing for it's size/weight) ... but it really IS too good to be true w/o throttlestop!

Also, over on OCN we have a thread going about this laptop, and people are starting to experiment w/adding additional heatsinks onto the heatpipe system (one dude used a bunch of nickels) and seeing temps drop pretty dramatically ... apparently, the system lacks proper mass and surface area, but increasing it by just a bit seems to really help a lot.

Which makes Acer look even dumber letting this design get out the door TBH ... but what are we going to do ... set about tweaking, as usual I suppose

A great idea would be automatic profile switching based on what game you are playing. Unfortunately, I don't have time to add that feature. You'll have to continue doing this manually. That's not too hard and at least it makes your 38030TG a lot more usable. You could use ThrottleStop and set up a couple of key combinations so it would be easy to switch ThrottleStop profiles, as long as you remember.

Not sure why manufacturers continue to release such half baked products. This laptop is crying out for a properly designed cooling solution but Acer prefers to dream up some ridiculous throttling schemes instead.

VID voltage control works on the Core 2 CPUs but not on the newer Core i CPUs. Intel moved or eliminated the VID register when they switched designs and there is no public documentation about this so I am out of luck.

Check out the CPU power consumption numbers at different multipliers when your CPU is lightly loaded. I have never seen a huge difference because most Core i mobile CPUs automatically enter the C6 sleep state where voltage gets turned off. If you forget to turn ThrottleStop off, it probably won't make much of a difference at idle so no worries.

[Heartfixer]

Dear Uncle Webb.

You must remember me - on another forum my nick is Cosmin - remember the m11x R2 problem?

Well, I've done it again - it seems I never learn. Bought a Dell M6600 with this processor. Basically had some problems and had to upgrade from BIOS A07 to BIOS A12. Thus the multiplier gets cut to 27 and stays there after a couple of minutes of full load - be it Prime95, OCCT or 3DS Max. Well, Dell, this is the reason I bought this beast, 3.3GHz, baby.

Is there any way to make it so that I can set the TDP for this processor with TS? At the moment the options are grayed out, as you can see here:


Thank you in advance. M11x R2, never forget Also, Dell stinks

[unclewebb]

Hi Cosmin/Heartfixer. I remember you well from the M11x-R2 days. Those were fun times.

The Package Power Limits are grayed out in ThrottleStop because Dell decided to lock this feature in the bios. The only way you can adjust these values in ThrottleStop is if you can find a modified bios for your laptop.

The long term power limit is set to 45 watts. Long term at full load, your CPU will automatically reduce the multiplier so power consumption stays under this limit.

Edit: Based on the CPU-Z validation, I originally thought you had a 2920XM but it looks like it is a 2860QM. Post a screen shot of CPU-Z or ThrottleStop to confirm.

I think the 2860QM can only have the power limits adjusted higher a very small amount and only if the bios supports this feature. If the bios locked this feature, there is nothing you can do besides get a modified bios which may not exist for your Dell M6600 and might not be worth the hassle even if it does exist. No more increasing performance by 50% like you could with ThrottleStop and the M11x-R2 UM processors. Intel finally learned how to really lock a CPU down.

[Heartfixer]

It's a 2860QM but it's basically the same processor as the 2920XM, that's why CPU-Z shows it that way, screenshot is identical to the screenshot in the validation. I just don't have the Extreme Edition sticker on the laptop.

If this is true, I think I`m actually going to return the laptop and ask for my monies back, this is retarded. The processor can do it - I ran it @3.3GHz for a while now. It would get heated. The worst thing is that the BIOS update didn't help at all, but had to do it in order to get the Dell engineer to move his ass to my place to fix my computer. Basically, from what I understand, the A07 wasn't locked, but the A12 is... freaking kill me...

Dell tech support raeg incoming, stay tuned

P.S.: would it be possible to "hack" the BIOS? I'm p. sure there aren't any modified BIOSes out there, as these are usual a professional's tools and they don't always optimize stuff, they just buy it and use it, but for me an hour lost in rendering is an hour that could've been used for something else and at 27 multiplier VS 33, I think that's about right when having hours' lenght renders going on...

Oh yes, I'm mad


LE: 2860QM has 45W TDP and 2920XM has 55W TDP, this is a really sneaky way of making sure those that pay an extra thousand really get those couple hundred MHz extra VS the 2860QM, although this one's theoretical turbo speed is 100MHz higher than the 2920XM's.

LE2: I suppose I can't "downgrade" my BIOS to a previous version, now can I

[unclewebb]

Check out what mw86 can do with his 2920XM.

http://forum.techinferno.com/alienwa...d-results.html

The unlocked multiplier and TDP limit in the XM makes a huge difference compared to the 2860QM. The QM ends up being a bad joke because it is so limited by the 45W TDP.

The limits of the 2860QM are built into the CPU itself so different bios versions are not going to make that much of a difference. Even if your bios unlocked this CPU so ThrottleStop could adjust it, there are still limits within the CPU for both the multiplier and the TDP so you're screwed either way.

I guess you will have to trade your new laptop in for an Alienware M17x or M18x with an XM CPU if you want to significantly reduce your render times. With the proper bios, a laptop with an XM CPU can be a real beast.

[Heartfixer]

Well wait a second, the main idea is that I used to be able to run at 3.3GHz constantly @100% load and now I`m not able to do that anymore, period.

Read the link, daaaamn, 4.3GHz. I don't need that, really The TDP limit in the XM is only 10W more than the QM, is it really that unsurpassable? Proc was ok before this damn BIOS update, ffs.

Also tbqh I'm not trading my M6600 for that bad joke of m17x/m18x, I've compared them before I bought mine, they're utter rubbish in comparison.

At most I'll insist they replace my QM with the XM because of the mess they made with the BIOS, hopefully at no extra cost. Fingers crossed.

great tool

nice cant wait to use this on my laptop

[db87]

Is it possible to use ThrottleStop for locking the multiplier to 21 (turbo multiplier) with my i7 920 D0 desktop CPU?

I did try ThrottleStop and it went into turbo multiplier but dropped back to 20x when all cpu cores were loaded.

My MSI Eclipse SLI motherboard is not able to lock the CPU in to turbo multiplier, unlike ASUS and Gigabyte motherboards...

[unclewebb]

db87: Post a screen shot of ThrottleStop while your CPU is fully loaded with Prime95 or LinX / IBT. Also post a screen shot of the TRL and TPL windows.

A Core i7-920 can use the 21 multiplier when all 4 cores are loaded as long as you are not exceeding the Turbo Power Limits. If your motherboard bios has locked these power limits, I don't think ThrottleStop will be able to help that situation. If the values in the TPL window are grayed out, that means this register is locked.

Some motherboards simply crap out when trying to push these CPUs to 4000 MHz and beyond. I think the voltage regulator can overheat and they are not able to deliver enough power to the CPU socket.

When the C3/C6 sleep states are being used, a Core i7-920 supports a maximum multiplier of 22 when a single core is active. Post some more details so I can have a look.

ThrottleStop 5.10 Beta

http://www.mediafire.com/download.php?3s4jnz69d83jqua
http://www.sendspace.com/file/11ciyj

This is a time limited beta version.

- added adjustable Turbo Boost Time Limit for the unlocked CPUs.

- added an iGPU Throttle flag on the main screen that on my desktop CPU, seems to indicate when the Intel GPU is being throttled due to reaching the power limit. There is also an iGPU Log box that will be checked whenever the Intel GPU has been throttled so you can have a look at this box to see if any throttling was recorded while you were gaming. The documentation does not seem to be accurate so let me know if this feature works like this on the mobile CPUs.

- the new EX PROCHOT box should indicate if an External source is triggering the Processor Hot signal to the CPU and if this is forcing the CPU to throttle.

- added a FLEX VID setting in the TRL window so users with unlocked CPUs can boost the turbo voltage. Be careful with this feature. Unless you have an Extreme CPU and are pushing a very high multiplier, you should leave this setting at zero.

- changed the Set Multiplier value so it includes what value is being sent to the CPU. Instead of Turbo, ThrottleStop might show something like 40 T which indicates that you are requesting the 40 Turbo multiplier from the CPU.

- added a Task Bar option so you can minimize ThrottleStop to the Task Bar.

- added Windows 7 and Windows 8 Notification Area Icon compatibility. If you have any problems, use the Notification_Area_Cleaner.zip file to clean out your Windows icon cache. This handy utility can be found here and does not require a reboot.

ThrottleStop 5.10 Beta 2

[rintamarotta]

Im trying to set invidual Turbo multipliers for my cores, example Core1 53, Core2 48, Core3 48, Core4 48 (because Core 1 can do 5.3Ghz @ 1.4v and Core 2 can max. 4.8Ghz @ 1.4v)

How ever something forces lowest multiplier for all cores even when it should be possible to set Core 1 higer than other cores.
Example if i set Core1 53, Core2 48, Core3 48, Core4 47, it will force turbo multiplier of 47 to all cores.


CPU is Intel i7 3770k
Motherboard is Asus Maximus V Extreme

Something is going wrong here, and im not shure what it is.

Video about problem here (it might still be encoding) : http://www.youtube.com/watch?v=lOt_5...ature=youtu.be

[unclewebb]

All active cores in any Core i CPU are locked to the exact same multiplier. It is physically impossible for different cores to use different multipliers. You can have threads and cores going into various low power C States but as soon as those threads and cores become active, they will be using the same multiplier as the other cores that are already active.

In ThrottleStop and in the bios, when you are selecting the Turbo multipliers, you are selecting what multiplier your CPU will use based on how many cores are active.



The above screen shot means when 1 core of your CPU is active, your CPU can use the 53 multiplier. When 2 or 3 cores are active, the CPU will use the 48 multiplier and when all 4 of your cores are active, the CPU will use the 47 multiplier. Those values are the maximum. If your CPU is too hot or if it is consuming more power than the TDP limits then it is possible that it will throttle and run at a lower turbo multiplier.

I had a look at your YouTube video and ThrottleStop looks like it is working correctly. You are trying to make your CPU do something that is not possible. This limit is at the hardware level and can not be changed with any software.
