I have no problem with corruption of the ext4 partition but I noticed that in openELEC B4 I had to set my sdram clock down otherwise it hung at the color gradient screen. But no problems whatsoever with corruption and I run a high clock 1050/400/500 +4 before before B4 it was 1050/500/500 +4 not that it matters so much I can only conclude something changed in the firmware in B4.

I run this overclock 24/7 with force_turbo=1 never had any crashes or corruption, unless I ofcause go higher but that usually just result in a crash. I have a older no name/no sticker 4GB card and a 16GB Kingston class 10.
No corruption on either card, anyway just sharing my experience and that something happened in B4 firmware that limited the sdram clock at boot for me.

This is on a 512MB board as said before I have memory leaks happening on the 256MB when streaming HD content it does not overclock as much but I was running it at stock clock ofcause to eliminate that first. Oh well that's another matter..
