TRUST me you will have errors if you are SPP/MCP was unstable. As far as going out of the "green" zone on your board. DONT DO IT! A lot say to set SPP to 1.5v for above 450mhz stable. I dont agree. I ran my E8400 @ 450mhz or 4.05ghz for months with low "green" voltages on all SPP/MCP/Vcore/FSB. I even kept spp<>mcp to auto. Not a bit unstable.
If you are having Orthos stability issues than maybe (sine you are only 400mhz) RMA that chip or motherboard. Especially if you have to go outside "green" voltages.
The E8400 should be able to go to 400mhz or 3.6ghz without touching voltages (accept) memory, and even should be able to set voltage blow what auto does. If not I would recommend RMA.
This was my first OC so I was hoping all AUTO settings would work. However, I was experiencing lag and freezing while playing Crysis and was unable to run the Crysis Benchmark with these settings --> 1900x1200;All High; 4xAA. I tried the benchmark 7 times and it crashed everytime with a blue screen. Then I went into the BIOS and increased the FSB from 1.30 to 1.35 and the SPP from 1.3 to 1.4 and it ran the benchmark the first time. Also the lag in Crysis has been reduced.
