The Continuous Electron Beam Accelerator Facility (CEBAF) 12 GeV upgrade reached its design energy in December of 2015. Since then CEBAF has been deliver-ing 12 GeV beam to experimental Hall D and 11 GeV to experimental halls A and B in support of Nuclear physics. To meet this energy goal, ten new 100 MV cryomodules (80 cavities) and RF systems were installed in 2013. The superconducting RF cavities are designed to operate CW at a maximum accelerating gradient of 19.3 MV/m. To support the higher gradients and higher QL (~ 3×107) op-erations, the RF system uses 13 kW klystrons and digital LLRF to power and control each cavity. This paper re-ports on the C100 operation and optimization improve-ments of the RF system and cryomodules.
