Most motherboards made in the last 15 years or so can disable spread spectrum and usually default to off. "Name brand" computers not so much.
The idea behind spread spectrum is to modulate the CPU and other clocks to spread radiated EMI across a larger spectrum so OEM systems can pass FCC/EU radiated emission standards.
The main source for radiated emissions is fast rising edges on data and clock signals.
From an EMI standpoint faster = noisier.
