think that could be the limit of pci-e feq but again it could be any card that on the bus holding back on 119
so you may find you can go higher by turning off almost every bit
like lans as they are pci-e chips raid chips and graphic card could hold back
but i will find out if we can get a bit more or not on the pci-e but why you want 120, may i ask and no, you need the mod to get. the bios can not fix
it a wrong track link on the north chip that what the mod is doing

it should have been picked up in the early days but no one seem to ask or try pci-e freq
even i missed that but then again i do tv card testing and i know a lot of tv cards on pci-e get upset about the bus over 104 lol
so i dont touch my self
