Some peculiarities on temperature dependences of conduction and dielectric permittivity (growth up to high magnitude 105-106) have been found in (TMTTF)2X (X=Br, PF6) in the temperature range between room temperature and temperature of transition into spin ordered states. These features are connected probably with charge induced correlation and appropriate development of 4kF charge density wave in this temperature range
