Very nicely done, you must have won the silicon lottery.
I personally cannot get my PII 1090T over 4.2GHz, temperature is far from the problem as it is liquid cooled but, i've tried multiple times and it always quits right around there.
Still a great chip but, wish I would have gotten a better binned one :thumbsup2:
5GHz is quite the accomplishment :grin1: good luck!
