Could the CPU fail badly enough that the POST might not make it past the C1 error and into one of the CPU POST messages?

NOTE: I never verified if my DFI was bad or not. I RMA'ed it. But the Phenom is definitely bad in a different motherboard with two different sets of memory. (The 1066 memory has tested fine for a day including 2 passes of memtest. At 800 speeds at this time. No overclocking until everything has worked for a few days at stock.)
