Back in 1998 I heard rumors about a blizzard 1260 over klocked to 133MHz.
I don't know the details about the 1260, but my PPC card has a selective multiplyer. though you have to solder on the board to do so. But AFAIAC i only know of the possability to select between 0,5(for 040) and 1(for 060) using original 50MHz oscillator.
I would really like to know if there is possible to increase the multiplyer somehow....
Especially if that is possible to do on a 1260 of some kind...
