Actually I got around that
I did advanced RMA, Paied $20 for them to ship a board to me first, then I ship mine back. So I don't have to deal with their BS and delays and I can use the same box which would have probably cost me about the same amount I payed for Cross shipping.
And yeah, it wasn't the 1900 FSB that killed my MCP, MCP is southbridge. It was the fact that my motherboard is curved (not flat on a table) and its not making good contact anymore.... If I change the screw tension on motherboard standoffs, it changes temperatures of the chipset which means I have a faulty cooling system.
My new board arrives tomorrow but Im leaktesting my WC kit today and tomorrow so I can't really post results with how bad ass the new board is..... yet!
