DFI Alpha Setting
bus#0 dev#0 func#1 0ffset#94,95,96,97

if u want to check alpha setting with WPCREDIT plz change it to 32bit mode.....
from left to right :-

- T(DOE) : Selectable Value: 0,1,2,3,4,5,6
- T(RRD) : Selectable Value: 0,1,2,3,4,5,6
- T(W2P) : Selectable Value: 0,1,2,3,4,5,6
- T(W2R) : Selectable Value: 0,1,2,3,4,5,6
- T(REXT) : Selectable Value: 0,1,2,3
- T(R2P) : Selectable Value: 0,1,2,3,4,5,6
- T(R2W): Selectable Value: 0,1,2,3,4,5,6
- Reserved : always 0

try loosen it to 2-3-3-3-3-3-4... or even loosen.. u will gain more stable FSB... no performance hit.. dont worry

here is other register if u want to do further tweaking...
