" rel="nofollow - Does the "Spread Spectrum" setting exist on the X399 Taichi somewhere? I combed through the UEFI and didnt see it, but I could also be blind too. My bus speed is dancing around all over between 99-101MHz, so wanted to see if I could disable spread spectrum.

If a Spread Spectrum option existed in your board's UEFI/BIOS, it would be in the OC Tweaker screen.

I don't have your board, and UEFI updates are not always updated in the manual. Can you set the BCLK rate to 100.0 MHz with the Hyper BCLK engine your board has?

Sorry about long reply. The refclk option seems to be ignored. I set it to 101 or 99 or 120 or 90, its ignored and always sets to 100 actual refclock (plus/minus the fluctuations)
