Overclock+Update Help !- Point Of View Mobii 7.0", 4GB


Oct 20, 2012
Hey there!
I bought a ''Point Of View Mobii 7.0", 4GB'' about a week ago , works great but got some lagg spikes that really annoy me , my CPU Master tells me that im running on 720Mhz and i'm wondering if i could overclock that a bit , lets say to 800Mhz or more.
The tablets is Rooted :)

Update Help.
Im running on a ''Kernel Linux version 2.6.29'' Version KS-20101117 Single touch ''Modelnumber: Android for telechips TCC8902 MID'' And i would like to update my android.
When i choose for system updates it ask me where i got the update files , Well i don't got updates files and wonder if anybody got some updates for my device and could explain what to do.

I'm a total noob if its about tables so here are some pics in case that might help:
