We study a $D$-dimensional Einstein-Gauss-Bonnet model which includes theGauss-Bonnet term, the cosmological term $\Lambda$ and two non-zero constants:$\alpha_1$ and $\alpha_2$. Under imposing the metric to be diagonal one, wefind cosmological type solutions with exponential dependence of three scalefactors in a variable $u$, governed by three non-coinciding Hubble-likeparameters: $H \neq 0$, $h_1$ and $h_2$, obeying $m H + k_1 h_1 + k_2 h_2 \neq0$, corresponding to factor spaces of dimensions $m > 1$, $k_1 > 1$ and $k_2 >1$, respectively, and depending upon sign parameter $\varepsilon = \pm 1$,where $\varepsilon = 1$ corresponds to cosmological case and $\varepsilon = -1$ - to static one). We deal with two cases: i) $m < k_1 < k_2$ and ii) $1< k_1= k_2 = k$, $k \neq m$. We show that in both cases the solutions exist if$\varepsilon \alpha = \varepsilon \alpha_2 / \alpha_1 > 0$ and $\alpha \Lambda> 0$ satisfies certain (upper and lower) bounds. The solutions are defined upto solutions of certain polynomial master equation of order four (or less)which may be solved in radicals. In case ii) explicit solutions are presented.In both cases we single out stable and non-stable solutions as $u \to \pm\infty$. The case $H = 0$ is also considered.
