So for the default of 1.0, no damping is used. The smaller $$\lambda$$, the greater the damping and the the longer the convergence time. Therefore if the solver does not converge, start changing the relaxation factor to 0.9, then to 0.8 and so on. Values below 0.3 are unusual and if you need this, you should have a closer look to the math of your analysis. For cases, where you get a proper convergence you can set $$\lambda$$ above 1.0 to speed the convergence up.
