but how does it work ???

on your cpu-z screens (aquamark, superpi, pifast) there is always
bios 0219 for your rampage formula and your cpu is E0 stepping

arent all E0´s supposed to work with bios 0407 and above ?

i´m asking because i really like the board and just purchase a e8600
but all bios after 0308 seem to be "downgrade" for performance and
stability (additionally pci-e controller do not work and so on)
