Just remember to stay well away from "spread spectrum" or disable
it if possible. It's a 50-75 kHz FM to make the computer sneak

Actually, it's a sneak to allow 15 to 20 dB greater EMI from the
typical PC. The motherboard makers provide a control bit in BIOS to
disable spread spectrum for normal operation, informing the user that
it is to be enabled for agency testing only. The agencies should force
the BIOS writers to remove that bit, since it allows the hardware to
be rendered non-compliant under user control.
