CuriousG: you should try to draw your L1 bridge again, same thing happen to me. my avia (266) can't do 1.2ghz but once i drew my line again and swith from a super orb to a taisol 742092 with delta 60mm, it does 1.4 ghz stable. i personally can't tell the difference between 1ghz and 1.33ghz, maybe is just me
