The goal of this series of papers is to give a new non-commutative approach to problems about the density of reductions such as the conjecture of Joshi-Rajan, and the generalization of the conjecture of Serre. In this paper, we prove integral Grothendieck Riemann-Roch which was proved by Papas in the case ch(k)=0. As a corollary we prove an integral analogue of Kontsevich's comparison theorem, and we show that if a smooth projective variety X has a full exceptional collection then there is an explicit formula of the motive of X up to bounded torsion.
