My Dell E4300 hangs up deadly when Intel Speed Step is ON

It is actually on by default, so it took me a while to find out what is the reason. It hangs up after 3-10 minutes of using (usually online video streaming). Later I found way to reproduce it constantly, Prime95 in mode when memory is tested well. Firstly I blamed DIMM module and remove one module then another - result was almost the same (it hanged up after 10 sec instead of 2 in Prime95).

Then I started to play with BIOS settings, and eventually found that when I turn off IntelSpeedStep it works well, without hanging up. The bad is that it works on lowest speed 1500 mhz always and doestn' reach it's maximum of 2400.

Is anyone faced with such issue?

 

Check and make sure you have the latest BIOS version. The latest BIOS Revision is A17.

 

I would wonder whether there is something amiss with the CPU / mainboard so that it is not switching CPU speed / voltage reliably.

bios, chipset soft, drivers - everything latest

 

Have you checked your temps? I had a friend experience the same problem which I took apart the laptop, pulled off the heatsink and rethermal'd it. Didn't fix the problem so I just turned off the speedstep

His temps were way high and still are even at its lowest step. Out of warranty, he just deals with it.

 

yeah, seems the same thing with me
