We present preliminary results for the determination of the leading strange and charm quark-connected contributions to the hadronic vacuum polarization contribution to the muon's $g-2$. Measurements are performed on the RC$^{\star}$ collaboration’s QCD ensembles, with $3+1$ flavors of $O(a)$ improved Wilson fermions and C$^{\star}$ boundary conditions. The HVP is computed on a single value of the lattice spacing and two lattice volumes at unphysical pion mass. In addition, we compare the signal-to-noise ratio for different lattice discretizations of the vector current.
