Overclock and Undervolt T4200

Hard mod steps:

1. open the case
2. remove heat sink
3. remove CPU
4. use thin copper wire to connect the VID4 pin hole to VCC hole of the socket (undervolt 0.2V)
this is a bit hard because they are a few pin holes apart
5. again use thin copper wire to connect BSEL1 to VSS (overclock to 266)
this is easy as the holes are next to each other
6. put back everything

for the location of the pin holes refer to
http://forum.notebookreview.com/showthread.php?t=390696 has the photo for VIDs of socket p which T4200 use.
and
http://www.xtremesystems.org/forums/showthread.php?t=223849 has the table for BSEL1
I believe this mod also work with T6 series

After mod with RMclock undervolt the cpu temp is really cool when idle at 1.6G. I think the ambient temp was about 16c


Under full load at 2.66G


Notes: I think this only works for non Intel chipset
