The ThrottleStop Guide

You can read about that feature in the included docs. Not too practical but good for a screen shot. If there isn't an updated bios version available for your laptop then I guess you will have to depend on ThrottleStop. I think the last computer I saw with this issues was a MSI desktop when running a Core 2 Quad.

Thanks for help!
I thought the same that the problem is in BIOS.

As far as I know, it supports any processor with an 800mhz fsb but i read the heat could be too much for the m1330s cooling altough a few people on here have done it.

I think i'll call Dell tomorrow and ask them, the gpu does still get quite hot under normal use but i think the cooling could be improved, maybe replace it and/or put some good quality paste on the chips as i don't think it's been changed since 07!

Cheers.

Here's an example I posted in the NBR Under Volting Guide of some testing I did with my 45nm T8100.

The "Undervolting" Guide

Running a 45nm Core 2 Duo at a reduced multiplier is not a great way to save power. You are better off running it at full speed, let it get a task done quickly and then that will enable it to get back into one of the deeper sleep states like C3 so it can save power. This saves more power than running a CPU with an intermediate multiplier. Here is a good paper that blows a hole in some of the myths.

Thanks for explaining.

But now I will tell you my behaviour:

As I told, I use P8400 (in Lenovo T500).

RMClock-profiles looks like this:



I have unlocked EIST-Bit by Bios-Mod and disabled SpeedStep in Bios-Settings, otherwise I could not turn EIST on/off in Windows.

So in Win7 (if RMClock is disabled), CPU is always running on Max-FID/VID - never on any C-State.

Your discription^^^ sounds to me, like regular Speedstep-function.

And I can confirm that on a friend PC wih a differend i7 it does say parked

Hey, there's a button called TPL which shows this:


What does it do?
Thanks.

You rocks! Fixed my CPU problems

xShadowCrisisx: That window you opened up lets you adjust the Turbo Power Limits (TPL). Many laptop manufacturers have locked this feature in the bios but it looks like your laptop has this feature unlocked so it is adjustable.

The newer 2nd Generation Intel Core i CPUs contain two limits that control when your CPU is allowed to use Turbo Boost. There is both a long and a short term limit. In your example, for 32 seconds your CPU can operate beyond 45 watts up to a maximum of 60 watts. It is not allowed to operate beyond 60 watts other than for a few milliseconds before Turbo Boost will be reduced which will reduce CPU power consumption to keep it under the maximum limit. If you are running your CPU fully loaded then being able to adjust the 45 watt limit a little higher should get you a little more Turbo Boost depending on what CPU you have. Your CPU looks like a non-Extreme CPU so Intel locked these down so you can only adjust upwards from 45 watts to 48 watts as far as I know. For XM CPUs, the sky is the limit. 2920 XM users have been pushing the envelope with this feature and some users are bumping this up to 130 watts. That will warm your lap up but will allow an XM CPU to really stretch its legs so to speak. Lowering these values might be a way to reduce the amount of Turbo Boost when you want to reduce heat output and perhaps maximize battery run time. I haven't seen any testing of this.

Your CPU package current limit is locked at 97 amps. That number is usually high enough that it won't be a Turbo Boost limiting factor. ThrottleStop has it grayed out because your bios locked the ability to adjust this and also locked the ability to unlock this feature. That's what the grayed out and checked Lock Current Limit Register box means.

For the record, ThrottleStop 4.00 works correctly with Intel Core i 2nd Generation CPUs.

I keep reading in forums that 2nd Generation CPUs are not supported but obviously that is not true. As long as your bios hasn't locked these features, the turbo power limits are adjustable with ThrottleStop.

Next time you ask a question, maybe move the top window beside the main window so I can at least see what CPU model you have.
My wild guess is it looks like a Core i7 2630QM.


Thanks for all the votes.
