I have an 850 on an MSI k7tpro2a with the kt133, I am running at 9.5*106 = 1007 @1.85V I can post up to about 1100 but windows doesnt boot above about 1050. It should definetely work for you at 6.5*133 and you could probably get 7.5*133 = 1000 I've heard pretty good things aobut the alpha, so you should be good. I would suggest using some Arctic Silver or Arctic Silver 2, I use AS2 and it dropped my temps across the board a good 4-5 degrees C from a standard thermal pad. Good luck!
