Yup.....
Mine did 2.2ghz (Xp3200+) @ 1.61v , 2.48ghz @ 2.05v - watercooled. Temps were nice and low and she loves voltage. That chip is curently in my second rig, my Aquca only needs 1.87v to hit 2480mhz.
With a pommi & 2v a guy hit 2600mhz, dont be expecting that high. 2.3ghz is a more realistic figure. If your cooling & PSU are good and with high enough Vcore 2.4ghz, very very lucky or water cooling 2.5ghz.......
