yes i was pushing 1.57-1.60nbv.but you know to be honest i was only using the dfi while i waited for my UD3P to get back from RMA.and i got to say it was frustrating not being able to go higher than 471,when i could easily do 525fsb with my UD3P&9650.so when i got my gigabyte back i quickly through in my quad and went straight to 500fsb+ and was very happy.if i was you and if you can afford it i would for sure get a UD3P,you'll love it.but remember the dfi p35 is much better in the memory dept
