How to Supercharge the M11x with Core i5/i7 UM CPUs

Ah ok, so do I untick the sync profile box then and set each one to what I want?
And I can go to 100 for gaming then? Are there any recommended presets for everyday use, gaming etc that I can use?

Thank you for the quick reply Im eager to get her running at maximum performance

 

Yes, untick the sync box to set up each profile accordingly. You don't alway have to use them.. I only turn on Throttlestop when gaming. SO I have only one profile with TDP = 30 and TDC = 30 (Haven't messed around with different levels yet.)

 

Ignore

Cheers, Paul.

 

This looks just awesome

 

Made a little comparison of using TS and raising BCLK.



1. BCLK @ 182 with TS on
2. BCLK @ 166 with TS on
3. BCLK @ 166 with TS off (stock OC)
4. BCLK @ 133 with TS on
5. BCLK @ 133 with TS off (stock)

The most interesting part for me is that if you are OCing without TS you are willing to get slower results... I have reapeated the test, there is no error here...

 

Is this using SetFSB? I take it not all i7's will be capable of 182FSB??

 

Yes, it's SetFSB.
Well, mine definately prime stable at 182 BCLK under full load with TS(14x182=2548Mhz).
But it randomly crashes when only one core is under load. This happens also when youre not doing anything just waiting on the desktop or surfing.
When it jumps to 17x multiplier it crashes. Thats 3100Mhz.
If it would be possible to ban the 17x multiplier it would be stable for every day use.
Maybe unclewebb can help us out?

 

Haha 3100Mhz, that would be nuts!

 

You are not the first person to notice this. Dell gives you an overclocking option in the bios but when fully loaded, it actually makes your CPU run slower.

Overclocking in the bios causes more power consumption which will send you over the default turbo TDP limit so your bus clock speed goes up but your multiplier goes way down and you will be left with a slower running CPU. ThrottleStop is the only option I have heard of that can fix this problem.

Unfortunately, the Intel design does not give you the option to disable the 17 multiplier. You get 14 when 2 cores are active and 17 when 1 core is active. If there was a bios option to disable the C3/C6 sleep states, that might limit your CPU so you would only get the 14 multiplier but that's obviously not worth it. You are better off if you can decrease your bus speed a few MHz and get back to a fully stable point while being able to still use the 17 multiplier. Save 182 MHz for full load benching where it's impossible for the 17 multiplier to be used.

These CPUs have a hair trigger. When lightly loaded, they will rapidly transition up to the higher multiplier on a regular basis. When testing for stability, run 1 thread of wPrime and then go into the Task Manager and use Set Affinity... to lock this task to a single core. That will increase the amount of time your CPU is using the 17 multiplier so you can see what BCLK setting you can get away with while still being stable. Try some Prime95 testing like this too with a single thread of Prime95 locked to a single core of your CPU.

 

Thats sad.
Well I've already tested out one core stability with 17x multiplier and the highest BCLK I can get without a crash is 175Mhz.

I love this processor.. If I downclock the cpu to 555Mhz and optimize everything for battery use I can get 5 hours of battery life with surfing...
With high performance It sucks the battery down in 2 hours with the same use.
The great thing is that I don't feel the machine slower with my power saving preset while surfing.
I ran wPrime as a joke on that preset. I was so curious. It finished over 120 ish seconds. With my overclocked über high performance preset it is 23ish seconds lol.

 

Can you use SetFSB to run at 111 MHz x 5.0 = 555 MHz?
Do you know what ThrottleStop reports for battery power consumption when you are set up for maximum battery life? When you are going for maximum battery run time, I think it is best to turn ThrottleStop off.

 

Yes I can set it to 111Mhz.
Ofcourse I think switching TS off for max battery life is ok, but what about setting the miltiplier to 5x and disable turbo mode?

 

csufy are you i7 or i5?
175Mhz FSB stable is very nice! Love how people are really squeezing every last drop of battery and power performance out of these babies!

 

This is my i7 and it's even stable at 182Mhz with full load...
175Mhz is stable at idle also.

 

That looks like you got some awesome results. I hope I can achieve something similar within the limits of the i5 i just ordered yesterday.

 

Ahhhh so I'm experimenting with my laptop temp while at idle and while playing games. (I'm using standing fan to reduce some temp too!)
At the beginning of the log it is my M11x R2 i7's idle temp and the very last one is when my laptop shuts down itself automatically.....
CPU @ 150 MHz
Game tested: NFS Hot Pursuit 2011
Am I eligible to ask Dell for fan/mobo replacement if they find out I'm using Throttlestop? I'm just scared that they will void my warranty @@

 

My best guess is that someone at Dell didn't do a great job installing your heatsink and fan.

I don't know how Dell will react if you tell them you are running ThrottleStop. In theory, you should be able to run whatever software you like on your computer. Your mobo and CPU and GPU are probably fine. You just need someone to put the heatsink on properly. If it was my laptop, I'd do it myself so I had a good idea that it had been installed correctly. Maybe try running ThrottleStop in monitoring mode only and see how high your temps go in the log file. That might be justification enough to get Dell to come out and fix this for you.

The bottom line is that other M11x-R2 users are not seeing those kind of temperatures when using ThrottleStop so something is not right with your laptop.

 

Well even the temp gets that high I can't hear my fan kicking in......
(but when it's new it's totally fine)

Edit: Here's another log without throttlestop enabled. Chipmod being throttled at 50 and the temp stucks there, my NFS HP stucks at 5~6 FPS

 

Chipset clock modulation should never be on during normal operation of an M11x-R2. Maybe your fan is dead. Your computer needs to be serviced to find out what the problem is.

 

Hi!! Just bought an m11x r2 i7 and thanks for this thread, but i'm having a sort of a problem here. After using throttlestop and making some benchs, the system do not disable turbo boost in bios anymore. I see this because when running 32M test with wprime it uses 14x multiplier even when turbo boost is disabled in bios. I can only disable it through throttlestop and dont even need to press the turn on button, only check the disable turbo box and exit the program.

So, the monitoring mode seems to be not so monitoring, am i right? And how can i restore the settings so that the options in the bios are applied? I mean, i disable turbo boost when on battery but i dont want to run throttlestop every time to disable turbo boost.

 

You can check or uncheck Disable Turbo whether you are in Monitoring mode or ThrottleStop is running. That option works independently of the on/off state of ThrottleStop.

If you boot up with turbo disabled in the bios and you don't run ThrottleStop then turbo boost should be disabled as long as you don't have a problem with your bios.

If you decide to run ThrottleStop, you can choose to use turbo boost or not. If ThrottleStop automatically unchecks Disable Turbo when you first run it, you will have to manually click on Disable Turbo before you exit ThrottleStop. It doesn't do that on my Core 2 laptop when I run ThrottleStop for the first time.

You could set up a battery profile in ThrottleStop and get it to do the Disable Turbo part for you automatically as soon as you pull the plug. Just check Disable Turbo in your Battery Profile and use the DC Exit Time option which will force ThrottleStop to exit however many seconds you want to after you switch to battery power. Give it a couple of seconds so it can switch profiles for you first before exiting. You can set ThrottleStop up to do exactly what you would like it to do but its not yet smart enough to read your mind.

When ThrottleStop is running, does it show 4 rows of data in the table on the right hand side? Also have a look in your Task Manager and make sure it is showing 4 separate graphs. I just want to make sure that you have Windows set up correctly. Some users accidentally disable one of their cores in Windows. If it only shows 2 rows of data or 2 graphs in Task Manager then that's a problem.

When you ask a question, it really helps if you include a screen shot of ThrottleStop. Click on the ThrottleStop title bar to high light it, hold the ALT key down on the keyboard and while holding that, push the PRINT SCREEN button on your keyboard. Open up Paint and Paste this image into Paint and then save it as a jpg or .png file. After that you can upload it to ImageShack® and then post a link to that image in this thread so I can have a look.

 

which checkboxes do i need checked for the i7 640um?

 

Did you read the first post yet? It explains how to set ThrottleStop when running a Core i7 UM CPU.

 

fair enough. i hope these changes are not permanent

 

Thanks unclewebb, this has made such a huge improvement during my gaming sessions

This may not be the best place to ask, but what exactly is the max multiplier for the i7? Things like CPU-Z and HWinfo show it being as 16/17x while whenever I run TS, it shows up as 14x, which had me confused.

EDIT: Actually, after reading around, it would appear that 14x is the max when both physical cores are active and that the only time it goes above 14x is when I'm running on one core. Is this correct?

 

Yep, you got it.

 

I wish I could make these changes permanent. Most M11x-R2 users that have tried this have been very happy with the results. If you are plugged in and overclocking, running ThrottleStop should be at the top of your things to do list.

amodar: CPU-Z shows a high multiplier at idle for consistent validation purposes. That drives me nuts too. You will find that ThrottleStop very accurately reports the average multiplier that your CPU is using. Full turbo boost can only be obtained when Core i CPUs are able to put unused cores into the low power sleep states. This shows up usually as an average multiplier that floats around a lot when the CPU is lightly loaded.

If you go into the Control Panel - Power Options and set the Minimum processor state to a low number like 5%, that can help get you a low but steady average multi at idle but there is no way to get a steady high multiplier, regardless of what some programs are trying to make you believe.

 

what power option is generally used by other users? i am currently on balanced.

 

I use 'high performance' when gaming and 'balanced' for everything else.

 

Unclewebb, thanks for the quick reply.

Yes, throttlestop shows 4 rows in the table and the task manager shows 4 graphs, so everything seems to be working fine.

I'm actually thinking that i do have a problem with my bios because i don't remember if disabling turbo boost worked before i use throttlestop

Another thing is that when i disable speedstep in bios, turbo boost is also disabled dont matter if it is enabled in bios, so i have to use the set multiplier to turbo in throttlestop to have turbo boost.

Anyone else is having this issues with the m11x r2 i7? Disable turbo boost dont work and disable speedstep also disable turbo boost?

For now, i'll try to use the throttlestop profiles to fix this. I think i need to make the profiles, check the start minimized box and put a value on the DC exit time box to some seconds, and everything will be automatically, am i right?

 

Unclewebb, i'm close to get exactly what i want, just one more thing. I did my two profiles but throttlestop should always be running to actually change ac/battery profiles, so what is the point of the DC exit time option? And i didnt find an option to start throttlestop with windows so that it identify my profile at startup, should i just put it to initialize with windows mannually? So throttlestop needs to be always running to manage my profiles, right?

 

You usually need EIST / SpeedStep enabled for turbo boost and Intel CPUs to work like they were designed to work.

Some users do not want ThrottleStop running at all when they are on battery power. The DC Exit Time option gives them a way to completely turn off ThrottleStop automatically when they switch to battery power. If you do this and then plug back in later on, it will be up to you to restart ThrottleStop. I don't use this feature. I prefer to have two different profiles; one for AC and one for battery power and then ThrottleStop can switch profiles back and forth when you switch from AC to battery and back to AC again. The AC profile can have Disable Turbo cleared and the battery profile can have that box checked.

So yes, ThrottleStop needs to be running if you want it to manage your profiles. You can add it to your Windows startup sequence by using the Task Scheduler if you plan to run ThrottleStop every time you boot up.

Thanks, i'll do that. But, if i want max performance i usually disable speedstep in bios and put the set multiplier to turbo, so that i never get a multiplier lesser than 9x and still are able to get full 14x or 17x in one core (for some reason, disabling that in bios locks me at 9x so i need the set multiplier). Is that a good thing to do to get max performance (off course, i overclock too)?

 

You should not disable EIST in the bios on a mobile Core i7 CPU. There's nothing to be gained by doing this. Try going into the Control Panel - Power Options and set the Minimum processor state to 100%. That's all you can do to maximize the average multiplier when lightly loaded. The Core i7 UM is not a desktop processor. There is no way to lock it to the maximum multiplier when it is idle.

 

Thanks a lot!!! I did that. Thanks for all the help and i promise that this is my last post...

So, i think in the m11x there is no point in checking the set multiplier box at turbo then, right? The only thing that we can do is to set up the TDP and TDC limits. In my tests, 30/30 gives the 14x multiplier and no improvement in wprime tests when i set to 100/100 or more, so it seems there is no point in putting a large number than 30/30. On the other hand, to save battery i put 10/30 and this locks me at 11.9x multiplier. 10/30 is a good number to save battery right? (but if i want to disable turbo boost when on battery that is no point in doing that too, because it will lock me at 9x multiplier anyway?).

 

Now you understand how these UM CPUs work.

Most users don't need Set Multiplier checked as long as you have EIST enabled in the bios. The less you need to check in ThrottleStop, the more efficient the program can run.

You could also try using some TDP/TDC numbers lower than 10/30 for a battery profile so you get some turbo boost but not too much. I haven't tried this yet.

If you don't want any turbo boost then you don't have to adjust the turbo TDP/TDC numbers since they will be ignored. Just click on Disable Turbo and you're done.

Try testing with the wPrime program too to make sure you are getting full turbo boost when you are fully loaded. Sometimes as the CPU heats up, the CPU can start to slow down a little so you have to increase the TDP/TDC numbers a little. This will depend on the CPU. I think 30/30 is good enough for most users but some like it higher.

wPrime usually works the CPU harder than the built in TS Bench mark program.

 

Unclewebb, thanks so much for your program!

I have an interesting question, is there a way that you can make ThrottleStop to help users to save extra power? Like to get the discharge rate for r2 users down to 8kmwh constantly?

Man I would love you even more if that could be done

 

You're welcome seraphkz. The next version of ThrottleStop will be more efficient but when trying to save power, the best thing to do is turn ThrottleStop off and turn everything else off that is using CPU cycles.

You might be able to use the ThrottleStop Disable Turbo option to get rid of turbo boost when on battery power before turning ThrottleStop off. For the M11x-R2, ThrottleStop is mostly a performance improvement tool. I don't own an R2 so you'll have to check with other users to see what's the best way to maximize battery run timer. I wish I could get my Core 2 laptop down to 8 mWh and still be able to see the screen.

 

Just now a dell engineer changed my mobo and my temperature is fine again.....
New CPU means I can overclock from 150mhz to 162 mhz too!

 

DivineAura: That's great news. Now you can go do some gaming and run a ThrottleStop log file and save it somewhere safe so you will have a baseline of how a properly functioning M11x is supposed to run.

 

I can't believe this isn't sticky'd yet.
I disabled SpeedStep in BIOS and I am now getting smoother frames. Is this normal? I remember reading here that SpeedStep makes Turbo work better or makes the CPU work better as a whole..?

 

Run a ThrottleStop log file while gaming with SpeedStep enabled in the bios and then do the same thing with it disabled in the bios. Make sure you play the same game at more or less the same part of the game. The log file should show if CPU performance is the same or not. I usually find that SpeedStep has to be enabled for the correct operation of the CPU but on some motherboards, there are exceptions to that rule.

This is already almost a sticky thread. I just keep coming back here and posting everyday. ThrottleStop is the best thing for an overclocked M11x-R2.

 

What should I set TS for gaming for my i5 r2?

 

hey what throttlestop setting is best for the R2 i5? Right now I OC'd i5 to 166mhz stable *knock on wood* and set TS at 30/30 but what is optimal for the i5?

 

Same as i7 I think... Power limits 30/30 or higher. Also unclewebb mentioned the less stuff TS is monitoring the less issues. (i.e. gpu temps)

 

I have an i5 and have come to find that 100/100 with a force TDP/TDC at 4 gives me the best performance. I'm sure this isn't true for everyone, but give it a try. Don't be afraid to test your settings with the TS bench tool.

 

Much love to Unclewebb.

Running i7, 8GB, 80GB G2 intel SSD
OC - 166mhz

TDP:TDC - 30:60
Force TDP/TDC - 8

wPrime
TS on - 22.241 sec (4 cores 14x167mhz) Max temp 64C
TS off - 33.526 sec (4 cores 9x167mhz) Max temp 54C

11 second improvement? Crazy. Thanks!

Anything else I should be doing to squeeze more performance from this chip?

 

Drop a user's wPrime times by 11 seconds and they come back looking for more.

Dell should have added this simple feature directly to the bios so users could easily choose maximum performance or maximum battery run time without having to rely on a third party app like ThrottleStop.

If you are down to 22.2s wPrime times then there really isn't that much untapped performance left. A few lucky users have been able to use SetFSB and have taken their base clock speed from 167 MHz to ~180 MHz but not all CPUs are going to be able to handle that.

You can try increasing TDP/TDC to 100/100 but if you are already getting a solid 14.00 multiplier while running wPrime, that won't help any. You could also try lowering the Force TDP/TDC option and see if that improves your times any. Your best chance at any significant improvement is by using SetFSB. There is a thread somewhere on NBR about using that with an M11x-R2.

I also wouldn't check Set Multiplier or either of the clock modulation boxes unless they are needed and I wouldn't monitor GPU temperatures either. Save as many CPU cycles as possible for more important things.

 

Oh I hope I didn't come off as unappreciative unclewebb. I am extremely happy with your program and am grateful for your help. Just wanted make sure I didn't miss anything, that's all.

I think I'll leave thing as they are. I'm a lil worrie about te temps when I'm OCing so I may tone it down a bit.

 

Just wanted to add a thanks to unclewebb for the hard work and info. I have set mine to 30/70 with a force of 8. I am getting a prime of 29. That's with 164 overclocking and also using gamebooster. I don't think the throttle stop setting are optimal yet so going to play around with them.
