I haven't noticed a difference with or without cpu margin enhancement on my q9450. And to be honest my OC is basically the same with 0704 and 1402. The biggest difference is 0704 only reads fat32 and 1402 reads ntfs as well, but misses my usb stick so one BIOS only reads flash memory and the other only reads my disk. heh.

I disable those too, except for the OC charger which really helps my p5q-e push my mushkin ascents further.
