The infrared properties of lattice Landau gauge QCD of SU(3) are studied by measuring gluon propagator, ghost propagator, QCD running coupling and Kugo-Ojima parameter of β=6.0, 164,244,324 and β=6.4, 324,484 lattices. We study Gribov copy problem by parallel tempering (PT) gauge fixing of β=2.2, 164 SU(2) configurations. Rather unexpected features of the unique gauge(fundamental modular gauge, FMG) are observed in relation of physical values vs the optimizing function.
