    I am trying to overclock 8400m GS on Dell 1420, however i do not have much experience in doing this, i understand all the dangers in doing this and i know that overclocking technically is not safe. By default: GPU Speed is 400 Mhz and Memory speed is 500 Mhz with 57-60 C idle GPU temperatures and 79-81 C playing something demanding like Empire Total War.(all the readings taken with nTune and the NVMonitor)

    From doing some reading, this looks like the max temperatures people recomend even when overclocking.

    When i try to overclock the GPU to 500 and Memory to 550 the temperature rizes to 85 C but the performance does not increased much, yet when i overclock it to 600 GPU and memory to 620, the performance increases significantly enough, however the temperatures goes up as high as 95 C.

    I was wondering if anyone had any experience with overclocking these mobile cards and running them overclocked for a while? Has anyone found any combinations stable and semi safe while running them for a while? Also, does anyone have any suggestions for semi-safe temperatures on these mobile cards?

    Thanks alot for all the help!

    I've been messing around for quite some while now on my 8400M GS 256mb ..

    THe higher i had the temps go while O/C was 91 wich isn't that bad ...

    usually i O/C it at 600(Core)/425(mem) and it doesn't get higher then 84-85 and get significant improvement ...

    Here's a good thread for you :
