Just wondering if this was a good week or if anbody had any info on it??
BTW its a T-BIRD 1.33 Ghz

We could tell it was a T-Bird 1.33 with 133mhz FSB just by the stepping

It's suppose to be one of the best one's out there for that particular chip. A friend of mine has one and it's doing 1.6ghz on air. Not sure the specifics of the settings he used though. Good luck!
