E6400 overheating throttling

Thanks a lot, you've saved me big time!!!

 

so guys I am back on this thread. previously I didn't have this throttling problem, but now with the summer kicking in I actually do. i have the latest bios and everything, I've been using rmclock to keep temps down but now it's impossible, so as soon as temps go above 45-46C the computer becomes very sluggish, the resource monitor clearly show throttling with a Max frequency of 25%. the cooling system is a joke and this is supposed to be a business laptop worth $1200+? I am glad I didn't pay full price and got it at the outlet.

anyways, do you guys think at this point it needs a new motherboard/thermal paste/heatsink?

 

If you are using RMClock then you should be able to control the throttling by enabling throttling in RMClock and selecting only the 100% index. That was my fix for the throttling I had in the early days of the E6400 when the BIOS was set to throttle the CPU if connected to a 65W PSU.

john, that could be a temporary fix but it's still unacceptable that I have to tinker with this thing so much, come on, this is an expensive top of the line machine.
dell fails.

 

I agree. In my case Dell should not market the M2400 as dockable with the Advanced E-Port supporting 2 monitors if such a setup causes its CPU to perform frequently at 7% of its capability under certain conditions under minimal load.

What happening is that Intel GPU on the north-bridge is too hot for that processor and throttle occurs. This problem is not Dell exclusive, it does affect other laptop.s, (hence why Intel moved it out of there and included in the Core i mobile series CPU's.

A potential, untested fix, is to use high grade thermal paste to replace the thermal pad used by Dell. This should theoretically help. As I don't have the issue (Nvidia GPU), I can't test it.
A good thermal paste is: Arctic Silver 5 (http://www.newegg.com/Product/Produ...008&cm_re=Artic_Silver-_-35-100-008-_-Product)

 

goodbytes, i appreciate your suggestion and i have the knowledge to replace the thermal pad, but I have neither time nor patience to fix myself a system for which I have a warranty and that shouldn't have such huge problem in the first place. If lenovo had better deals at their outlet i would have already sold this e6400, i think what sold me with dell was the 3 year warranty. but all the latest latitude line has had huge problems, remember the e4300 failure?

 

Not quite. My E6400 also started overheating recently even though I have the Nvidia GPU. My GPU temperature reaches 103º when gaming, with no overclocking.

I'll call Dell soon and start whining, maybe I'll get a E6410 replacement? That would be cool even though I'd be happy enough just with a stable E6400.

Oh and I sure also have the throttling problem which doesn't affect me because I use the Throttlestop program (similar to RMClock but easier to use).

 

i think it would be really hard to get an e6410. also my problem is that i am in europe but i have a us system with US warranty.

 

Yeah, that was wishful thinking. But I think I'm entitled to get a working E6400. I'll take a look at the fans, but I cleaned them about 3 months ago so I don't think that is the problem. If the fans are clean I'll call Dell and see what they say.
