Prime95 runs the same speed even after Overclock

I overclocked my Q9550 2830 to 3400 MHz.
Updated FSB from 333 to 400 and increased the voltages.

I thought the faster clock speed would increase the performance and reduce the iteration time to test an exponent.
However, when I run Prime95, it reports the same amount of time per iteration as before the overclock.

Is this correct? Should Prime95 run faster on an overclocked machine than a non-overclocked machine?
Is there a setting in Prime95 I need to change?

Thanks!

Yes, CPU-Z says 3400 MHz
Multiplier x 8.5
Bus Speed 400 MHz
Rated FSB 1600 MHz

Memory
DRAM Frequency 400 MHz
FSB:DRAM 1:1
5-5-5-15

Any ideas? Thanks!
