In this paper we study strange matter by investigating the stability window within one version of the QMDD model which suffers a thermodynamic inconsistency at zero temperature and check that it can explain the very massive pulsar recently detected. We compare our results with the ones obtained within the MIT bag model and see that this version of the QMDD model can explain larger masses, due to the stiffening of the equation of state.
