We prove that the moduli space of Calabi-Yau 3-folds coming from eight planesof $P^3$ in general positions is not modular. In fact we show the strongerstatement that the Zariski closure of the monodromy group is actually the whole$Sp(20,R)$. We construct an interesting submoduli, which we call\emph{hyperelliptic locus}, over which the weight 3 $Q$-Hodge structure is thethird wedge product of the weight 1 $Q$-Hodge structure on the correspondinghyperelliptic curve. The non-extendibility of the hyperelliptic locus insidethe moduli space of a genuine Shimura subvariety is proved.
