Overclock Crash

[matrix]

I have a c760 currently running cacko lite 1.22 w/hotfix

If i overclock the c760, after a short while the system starts getting crazy.  and will eventually require a hard reboot.  the logs show complaints about crc checksums on mostly the /, /home, and /usr mounts.  the exact error locations and affected mount points vary, but it always happens and eventually requires a hard reboot.

I do only use sd media.

I originally thought this might be heat related, but now think heat is only one big factor in this problem.  it will eventually happen no matter what i do, but if i run mplayer (via kino or otherwise) i can be sure that the system is hosed when I get back to the system.  If i use my symbol wifi card or am charging, there are more errors and the system gets really unstable.

a forum search for overclock crash didn't turn up anything.  the main overclocking thread mentions the system can get unstable after overclocking especially if you are charging.  but it looks like many people successfully overclock for video and games without problems.  

anyone care to share their own experiences with overclocking, particularly with cacko on a 760, but any at all would be welcome

Iv been running 1.22a full fat on my c750 for months and run "normal" on battery and "overclocked" on power with no problems.  I just reflashed with 1.22 thin and fixpack "a" which also seems stable (but quicker).

Do you have any other modules running? bluez / vpn  has this alwars happened or is a recent occurence if so have you installed any sw / changed any configs?

There is only one option when system is unstable - don't overclock. Overclocking is never garanteed to be successfull.

Overclocking does save on backlight though...... ;-)
