When I got an error before 10 seconds it was because my memory was unstable, but your memory at 445MHz CL5 shouldn't be causing the instability...perhaps you have a bad stick of memory, in which case you should run memtest just to be sure.

Also, try not to use auto voltage when overclocking; BIOS doesn't have a clue what the optimum voltage is for any particular component so it just gives a blanket amount, and that's not going to help things. What voltage options does your BIOS give, and can you post your current settings?
