Mine oc'd since july at 900 Mhz with lv load. Very stable no issues.
Tried lv@950 Mhz rebooted after 2-3 min.
tried stock voltage at 1000 Mhz, worked fine, until i ran streaming video over wifi. rebooted after 3 sec....
Then back to 950MHz with stock voltage. Ran fine for about 2-3 hours, but then suddenly device rebooted again, no reason why.
So now back at lv kernel at 900MHz that's the max. what my device can handle...
