dodgy motherboard and dont know how to overclock with it

I recently upgraded to a Duron 800 witha beatsty super orb fan :but (there is always a but) the motherboard I purchased - I enquired if it overclocked well and she replied ahhh yes ahhhh veryy well - and any way the story goes I installed it all realised there were no jumper switches cant change cpu sppped or voltage in bios nohing - It is a GA-71XE4 gigabyte

does anybody know how to overclock one of these pieces of **** Oh and no I can't afford a new motherboard ( i am poor at the moment)

Possibly with SoftFsb or another program like it

if you go back to the same person meybe she will let u exchange for another board(i know nothing of this board).if you r here you probably know more about oc'ing than most vendors.im a trucker and have been to shops all over the country,whenever i ask about anything remotely involved with oc'ing they get a glazed look in their eyes.i have been searching for a haetsink that i can get without ordering online and paying shipping.they always show me the one i allready have and i say "i have this ,what about one for oc'ing"there is that look again.if you read alot of post here you will get a good idea for a mobo you can use to oc....just a suggestion.
