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

An M11x-R2 should not be hitting 90C, even if you are overclocking and using ThrottleStop. Time to pull your laptop apart and clean out the dust and re-paste your CPU if you have to.

After that, run a ThrottleStop log file so you have a record of what temperatures you are hitting and if you are triggering any throttling.

 

Thanks will check it out this weekend ... seems to have at least temporarily stopped today. Is 90C the magic number i.e. what's the threshold? For some months it's been hitting 87C.

 

Max. 96C with laptop fan. LOL

 

For the i7 640um the max TDP is 18 here is the spec of the cpu.
Intel® Core? i7-640UM Processor (4M Cache, 1.20 GHz)

 

And if you have a 640UM in your M11x-R2 and use ThrottleStop and read this guide; you can go significantly beyond the maximum TDP.
Head back to page 1 and start reading.

 

What is the best settings in throttlestop to i5 520UM?TDP/TDC - OC stable at 150Mhz!!!

 

hi,

I decided to overclock my M11x R2 (i7) today and tried to play battlefield. I overclocked in the bios to 166 MHz, and used throttlestop to change the TDP to 30. I do notice a fps gain, but my temps were getting pretty high. Once my core temp reached 100 degrees I decided it was enough and shut the game down. I read on this forum that people get around 85 degrees max... Why is mine getting at 100? I cleaned the fan and I have my laptop elevated a bit so it can breathe a bit better... But is there any way I can reduce temperatures? This is kinda scary!

 

I been following this thread for months, and used throttlestop, can someone help me answer this.

I have i5-520um

What should I set the TDP & TDC at? here are my results using wPrime 32m test.

My multiplyer was 12.0 x 164.34 MHZ (Should my multiplyer be higher then 12?)

OC bios 164, no throttlestop, 36.86 seconds (Multiplyer 8.75)
OC bios 164, w/ throttlestop (20 TDP/60 TDC) 26.801 seconds (Multi 12.0)
OC bios 164, w/throttlestop (30 TDP/30 TDC) 26.899 seconds (Multi 12.0)

Whats the best TDP & TDC settings for the i5-520um for best/quickest results?

Im confused since OC to 166, my multiplyer (FID goes to as much as 14) but when I run the 32m test, it locks at 12.0 instead of going to 14? Shouldent it lock at 14 since thats the highest multiplyer?

Thanks

Edit: Just now for the heck of it, I went to see if I could OC in bios from 164 MHz to 166 MHz and its stable!

My 32m test is 26.211 seconds now (12 x 167.1 MHz = 2004.1 MHz) , is that pretty much the best im going to do with i5-520um? I used 30/30

 

The Core i5-520UM is only allowed to use the 14 multiplier when 1 core is active and 1 core is asleep in C3 or C6. When both cores are active, the maximum multiplier is 12. By using ThrottleStop, your CPU appears to be working at its maximum possible speed.

You chopped 10.5 seconds off of your wPrime 32M time. You must be doing something right.

Edit: Some motherboards support SetFSB or a similar utility to go beyond the 167 MHz limit. A good CPU will max out a hair or two over 180 MHz.

m11x r2 i7 u 640

I'm OC'd in bios to 162 with stepping and turbo enabeled. I have Throttle 4.0 installed and have set multiplier checked and set to turbo with a TDP of 20 and a TDC of 60.

The problem is my prime test runs 36ish seconds and when I'm watching the clocks on throttle while it's testing the multipliers never go higher than 9.99 and my clock speed is only 1500-1600 mhz because of it. Any idea's? I've read through the thread and due to the small amount of simple steps I can't see what I would be missing

 

Hi All,

I have an i5-520UM R2. I am OC'd at 162 in Bios and running TS 5.0. I noticed an issue I'm hoping someone can help me out with.

Current TS setup:
TDP = 30
TDC= 30
Force TDP/TDC = 6

When running wPrime (v209) my 32M time is 45.711 sec. When using the 32M TS Bench I get a time of 76.588. While running the tests my FID stays steady at 12.

I am puzzled why there is such a variance between my benchmarks and other I5 owners that have posted to this thread. I noticed in the "Chip" column in TS that this number steadily stays at 62.5. Its my understanding it should be at 100. I'm not sure why it constantly remains at 62.5

I checked MS Config and the number of processors is unchecked.

I am not sure what I should to do to improve my performance. Any recommendations?

~Update~

When writing the post above I was using the wrong power supply (60W). Once I used a 90W supply I was able to achieve 100 scores for the Chip column.

WPrime is now showing a 27.296 sec score, and ThrottleStop's internal benchmark shows 46.572.

I am new to overclocking, so I'd be grateful to hear any recommendations on improving my I5s performance.

 

The CHIPM column stands for chipset clock modulation. It is a method used by manufacturers to throttle your CPU to a crawl. 62.5 means your CPU is running at approximately 62.5% of its potential. You definitely want that to be showing 100.0 all the time.

Glad to hear you got your problem solved by using the appropriate power adapter. Your wPrime time looks very good now.

 

So after installing Windows 8 on my R2, I don't think the C state limit is working. I don't remember which setting I had it on before in Windows 7, but it got rid of that awful high pitch whine coming from the CPU when idle. Now I've tried every combination and can't seem to get rid of it in Windows 8. I've tried ThrottleStop 4.00 and 4.10, is there a newer version I should use?

 

I read about the last 10 pages - I figured that's where the latest R3 Sandy Bridge users would post. Thanks for your replies to us, UncleWebb. For us with all those grayed-out boxes is there any way to un-grayed-out those boxes? Are those options than can be unlocked on the BIOS (by people who unlock BIOSes). All general next-step-to-preventing-the-power-saving-on-R3 advice is much appreciated!

(I think you noted this before, but most Sandy Bridge peeps seem to use TS to throttle more than overclock in order to prevent odd slowdowns - def my case as well; thanks for that advice too)

 

Hey unclewebb!

I never got to thank you for this wonderful program,
when I first got my M11x R2 (which was probably a few years ago now) I was a bit disappointed with the performance.
But when TS first came out it was all so exciting being able to OC the processor like crazy!

With the stock RAM sticks I was able to OC to 166MHz.
Sometime ago I purchased new RAM sticks and I can sometimes OC to even 185MHz, but it's a bit unstable.
I usually OC up to 180MHz, so thank you once again for making this laptop even better than it is.

I've reached under 20 seconds with wPrime on 32M tests many times.

Thank you once again and I hope everyone has the luxury of running this on their R2 with high MHz!

 

jusalilpanda : For the R3, if items are grayed out in the TPL (Turbo Power Limits) window then the only way to unlock these values is with an unlocked bios. You might find something in the R3 threads.

Shimmycocopuffsss: 180+ MHz for the BCLK and sub 20 second wPrime 32M times is very impressive compared to how the R2 was originally shipped by Dell. It was good times back in October 2010 when ThrottleStop was being fine tuned to help out the R2.

When changing the BCLK in Windows, make sure that you are not screwing up the internal system timers. This was an issue for many Asus laptops but I can't recall if this was a problem for the Alienware M11x-R2. Check out this thread for more info about what I am talking about.

Hello, I am having a problem where throttlestop is not locking my m11xr2 at turbo speeds when plugged in. I try to play WOT, and when I open it, CPUZ says my multi drops to as low as 2 sometimes. any advice?


EDIT: it seems to only occur when the laptop is plugged in. when I pull the cord, it throttles up immediately, and drops back down when I plug it in

 

A 2 multiplier is not physically possible in one of these CPUs but that is how CPU-Z informs users that their CPU is being throttled. Many Dell laptops use chipset clock modulation throttling.

Turn off CPU-Z and then run ThrottleStop and turn on the Log File option. You need a record of your CPU's performance so you can find out what is going on. Copy and paste some data to www.pastebin.com so I can have a look.

It's possible that your power adapter is starting to fail. How long have you been using ThrottleStop and when did you first notice this problem?

When this happens, if your power adapter signals your laptop that it is not capable of delivering full power then your laptop will throttle your CPU to reduce power consumption.

 

the signal pin broke off of my original 90w cord (causing the clock to be locked at 6x and the battery to not charge), so I bought this one, which has worked fine for a while (about 1 year) before I started noticing the problem. the battery still charges.

Also, I am using a cooling pad, HWMonitor reports the temps never pass 80 C

EDIT: pastebin: http://pastebin.com/HT33UR71

well it seems my laptop charger has given up and is not signaling properly (battery no longer charging), thankfully by checking the clock modulation and chipset clock mod boxes, I can force turbo mode even without the proper detection. off to buy a new charger I guess.

 

The log file you posted makes it easy to see the chipset clock modulation throttling. Hopefully with a new power adapter, your log file will show 100.0 like it should be showing without having to use ThrottleStop to try and force it to 100.0.

 

yep new charger fixed the problem

still a great program though

 

Just today I noticed a huge performance drop in my CPU.
It turns out I'm only running 1 core and 2 threads only..
Is my CPU dying? D:
