E6400 overheating throttling

Another important thing to note is that the fins on the "radiator" of the heatsink should be checked that they are not clogging with dust. This is NOT the root issue to the problem being discussed here, but does aggravate the issue. I'm surprised it hasn't been mentioned already in this thread (at least not that I can see). A build-up of dust will certainly cause the core temperatures to raise faster, and has initiated the throttling issue for me several times. However, in support of the rest of this thread, while the temperatures did rise, it should not have been enough to trigger the throttling.

Somewhere on this forum, I previously saw a post with an excellent how-to on cleaning out the dust, complete with images showing the before-and-after with the dust, and specific to the Latitude E-series. Could someone please PM me if you can help me find this, and I'll update this post with the link?

In the meantime, it is easy to check, and clean if necessary. It only takes a few minutes, and I'd recommend doing this bi-monthly at the absolute minimum. Just remove the bottom cover (one-screw). Then remove the fan, and check for and remove any build-up of dust on the cooling assembly that the fan blows against. Pull out any large collections with nothing but your fingers, then finally cleaning up with compressed air works well.

 

I'd be interested in this too, and has anyone changed the thermal grease on the GPU with any good results?

 

Can someone upload please T11 BIOS?
Thanks

 

T11 Bios
The file name has to be renamed (exe)

~ AX842 ~

 

Why would you want T11 when theres new hotness?

 

ax842, Thank you very much for uploading me the Bios, very appreciate that!

one4spl, T11 is my curret bios and till A18, T11 is the best bios - less fan noise.
I want to try the new A19 Bios, but not before I have T11 Bios file to go back if It will not be statisfied with A19

 

Flashed with A19, and wen back to T11...
in T11 the fan more quiet

 

Decided to play a game of Cultris (a Tetris clone).

Results:



Enough to trigger throttling, but throttles to 1.6Ghz instead of 800Mhz.

Anyone know what the GMCH1 temperature is? It's awful high and drops really fast (instant 15-20C drop when alt-tabbing out of Cultris).

 

Are you it throttles and not just slow down to reduce heat and power consumption? What if you do a Everest System stability test (see under Tool menu), does your CPU increase in speed?

As for temperature, that would be your Intel GPU which is in the northbridge. If either processor heats up a lot, your system will throttles to prevent overheating. As your playing a heavy 2D game, I would guess that what you see is normal. This is proven as your RAM temperature is also way up.. this indicates that the GPU was using a lot your RAM (as it doesn't have it's own memory).

 

I would use RMClock, which explicitly shows throttling on its monitoring page, so you can be sure that it is not just speedstep at work.
