P45 DQ6 - Not saving overclock

[waqasr]

So my EP45 DQ6 was running my Q6600 at 3.8ghz fine for a few months until for some reason the overclock reset. Now since then i cannot overclock at all, not even a single megahert. Ive tried:

updating bios,
optimising bios settings,
taking cmos battery out
unplugging everything (battery, main plug etc) for over an hour.

has the board developed a fault or am i just doing something wrong all of a sudden?

 Hi waqasr,

Sorry but I suggest you delete your post. If possible, this Topic too.

And create another topic in the next section:
http://forum.giga-byte.co.uk/index.php/board,21.0.html

Please do not reply here, on this subject.
However, you can tell me the new topic to the new section, if you check the status of the battery of your motherboard.
