E6400 overheating throttling

Unfortunately with the dell e6400 it means it can drop down to 800 MHz when it's under load too.

Thanks for the tip on the Minimum Processor options. I noticed there is a "High Performance" Power Profile which already has this set to 100% minimum. I'll try it out and see what happens (whether the e6400 will try and throttle it anyway?)

 

When playing with the ThrottleStop tool, maximize your voltage before raising the multiplier. If you don't, that might be why it crashed before.

Run something like a RealTemp log while gaming without ThrottleStop turned on so you can go back and have a look at your MHz and see if there was any throttling going on. If you don't see any evidence of throttling then you don't need ThrottleStop. With the VID set first, you should be able to use the highest multiplier setting in this program to truly force maximum performance.

You can also run Prime95 and see what happens to your MHz and Clock Modulation settings after it has been running for 5 minutes with ThrottleStop off.

Use RealTemp 3.50 to monitor for both of these:

Thanks for the followups unclewebb. I tried this last night, and ran my laptop plugged in (but not docked) through the night while downloading some files.

This morning it's been docked for 4 hours without issue. Premature to say this has fixed the problem, but so far, so good!

 

That one setting is what controls your MHz at idle. Also disable C1E if you don't want your MHz sagging down. I've done some tests that show that SpeedStep does not always transition back up to the highest multiplier quickly enough so I usually leave my computer at the highest value. On battery power you might want to let it use the power saving features.

 

Spoke too soon. The issue came back about 3pm.

I have Dell coming out to "replace some parts" in the next few days so we'll see how that goes.

 

What sort of issues are you having? Your issues might just be the way this laptop is designed to work or the way you have it set-up. Post some screen shots of the problems so I can have a look.

 

So where do we post issues with throttle stop? I was given the afternoon off work so came home, it is not a particularly hot day atm, 35oC, put on a divx movie, an hour into it everything came to a screeching halt. Rebooted and monitored the CPU with RMClock and the temps with i8kfanGUI and put the same movie on, same thing 20mins into it, was able to close vlc player and hit the tickbox on throttlestop for "Disable clock modulation" nothing happened, I could see the % swaying between 12% and 24%, even then I tried ticking the tickbox to set multiplier and voltage, no avail. Strangely enough, when I tried to turn the settings i normally turn on in RMClock to stop the throttling that didnt work either...... I am on BIOS A19, is there something different about A19? I used to be able to stop throttling with RMClock on lower BIOS versions?

Might downgrade and try it all again. OH and I can get a BSOD by setting the multiplier to greater than 9.0 in throttlestop, which is I am guessing should be expected, as I cant set the multiplier higher than that in RMClock.

Anyway, have a merry Christmas everyone, and hopefully an unthrottled New Year

Unclewebb is the developer. PM him, that's his user name.

I wish I could help you, but I don't know much about the E6400's BIOS revisions.

CyrusB: Post some screen shots. I don't even know what CPU you're using.

If you have RM Clock properly set up then you probably don't need ThrottleStop.

When you tried to set the multiplier to the highest level in ThrottleStop did you set the voltage to the highest level first? If I knew what CPU you had I could look it up and tell you more about what's going on and what to try. Include i7 Turbo in your screen shots. It also works for Core 2 CPUs.

 

Hi everyone

I have only just found out about this issue with the e6400

I have a P9600. If I run it through a few intense tasks, it gets hot and clocks down from 2.66Ghz to 800Mhz. It then cools down (to say 50c) but the clock doesn't go back up to 2.66. Is this the throttling problem?

If so, what's the best way to fix it you have found so far? I have read a lot of the thread but can't find a definite fix. I am still on the BIOS it came with (circa May 09')

I am using Real Temp 3.40

Thanks

EDIT - Just been watching the temp/clock numbers for a couple hours now. Its gone back up to 2.66Ghz. I expect it will hit a high temp and drop back down in a bit though.
