Ah the trials and tribulations of testing out new parts.
If you don't mind me asking, what made you decide on this board?
As for the OC, you could start here:
Gigabyte GA-EP45-DS3R won't hold any overclock - XtremeSystems Forums Gigabyte GA-EP45-EXTREME Living Review - Clunk's Forums.
The air cooled links are probably what you're looking for?
I'll look more in the morning, but I've gotta rest now... apparently we humans need sleep, or so I've heard?
