We calculate the pressure (p), the energy density (ε) and the baryon density (nB) of QCD at finite temperatures (T) and chemical potentials (μ). The recently proposed overlap improving multi-parameter reweighting technique is used to determine observables at nonvanishing chemical potentials. Our results are obtained by studying nf =2+1 dynamical staggered quarks with semi-realistic masses on Nt = 4 lattices.
