I have seen the athlon 64 3200+ clawhammer overclocked to approximately 2.6 ghz. Has anyone seen the maximum overclock of a newcastle 3200 by comparison? Do the athlon 64 3000, 3200 and 3400 clawhammers and newcastles all overclock to the same overall core speed or do they get progressively better for example does the 3400 at 2.4 ghz overlock 200 mhz more than a 3200 at 2.2 ghz out of the box.
