I am one of those mysterious speedfan people. I swapped out the bios chip on my board with my wife's computer (both have this board in there) and the C1 fault isn't present on her computer with my bios chip. It boots up just fine. When I talked to DFI support they told me it had to be RMA'd to get it fixed. I suppose it possible it could be a CPU reseating thing, but somehow that just doesn't make too much sense to me.
