I'm wondering whether my mb would be able to get higher multipliers like 17-20 because future cpu will use them just would like to know if i would be able to upgrade without buyin a new mobo since i would only do that for the hammer.
The multiplier on all XPs are locked which means that AMD can now force any multiplier they want. Even if your motherboard has no setting for multipliers above 12.5>, the higher 13X... multipliers will still be there.
Nobody really knows if it will work. The MoBo manufacturers will only get hold of the TBred in a few weeks so nobody has really done extensive compatability tests. Rumors of the TBred availability on March 20 for purchase WERE FALSE.
