Freez with dreambox 800 hd

[winnydj]

Hello, I install a DVB-C tuner gray on my dreambox 800 hd pvr.
It works but every 20 sec I have a micro freez.
I work with OpenPLi 2.1 Image and oscam 8777.
Here is the configuration of my reader.

caid = 0100

group = 2
emmcache = 1,3,2

you might try to turn of the sensorbar. The DM800HD (not DM800HD SE) has a very slow processor on board.
