Both Asrock and Gigabyte limit the internal Pll to 136MHz, however on Gigabyte boards (where the external Pll is also present) the external Pll will take care from there. The frequency output of the integrated Pll seem to come even more inaccurate with frequencies past 130MHz, so this might be the reason.
Does this have to do with resonant clock mesh?
