Let OE be a complete discrete valuation ring and R be a perfect ring in characteristic p, we also assume R is a complete valuation ring whose valuation group is of rank one and non-discrete, we prove the Krull dimension of the ring WOE(R) of OE-Witt vectors over R is at least the cardinality of the continuum.
