I haven't tried myself but I remember reading in the past that Peg1&Peg2 accept different speeds. IIRC Peg1 accepts up to 666Mhz and if you try to overclock it more it will "underclock" to 400Mhz or something like that. In contrast Peg2 allows up to 800Mhz. There was an user in pegasos-forum.de who used an overclocked Peg2/G3 (can't remember his username, sorry) he posted pictures about ArtEffect running on MorphOS if that helps to find him nd ask him.
