Overclocking DM800HDse

It's possible to run your dm800se at 460MHz instead of the default 400MHz.

Al you need to do is move a resistor (R1818) from the bottom side of the mainboard to an empty resitor spot (R1819) at the top of the mainboard.

Please note, you need to have good soldering skills and preferable 2 small soldering irons to remove the resistor, of course smd soldering equipment would be ideal !

Is it safe to run the dreambox at 460mhz will it make it break sooner?

No, it is ok, as 15% is not really something that will change much on the CPU heat,
