CPU Spread Spectrum

I just pulled the bios battery to reset things. What is both CPU and PCIE Spread Spectrum?

It dithers the clock signals to reduce EMI at certain frequencies. I always disable them for overclocking. Unless you have interference problems with radio or TV, then re-enable them and see if it helps.
