Now i guess it's just a fluke but... 
Installed f4 official bios and...
got sooo cheesed off with not getting past 315fsb (always crashed around there) i just whacked it up to 350 and it runs beautiful.
Not ran sp2004 or anything yet but been on steam for a couple of hours and everything rock solid.
Read the link about c2d supposedly not liking prime so left it there.
Been posting a lot getting some good advice from you lot so thought i'd share my flukey gotten gains.

ps now scared to change it to see how far it will go
