We present the results of an all-sky search for continuous gravitational wave signals with frequencies in the 200--600 Hz range and frequency derivative (spindown) from $\ensuremath{-}1\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}8}$ through $1.11\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}9}\text{ }\text{ }\mathrm{Hz}/\mathrm{s}$. Together with the results from [ Phys. Rev. Lett. 123, 101101 (2019)], this search completes the all-sky survey for frequencies between 20 to 600 Hz on O1 data. It also demonstrates the scalability of our search on a parameter space 26 times larger than previously considered. The results presented here complement the LIGO O2 data results [ Phys. Rev. Lett. 123, 171101 (2019), Phys. Rev. D 100, 024004 (2019)] with comparable when not better sensitivity and do not rely on data with irregularities in the noise-subtraction procedure. We establish strict upper limits which hold for worst-case signal parameters and dedicated upper limits for generic $\ensuremath{\approx}0$ spindown signals, such as those expected from boson condensates around black holes.
