turbostat -v will tell you the max turbo for this processor.
Yes, it is normal to run above the TSC frequency --
indeed, that is exactly what turbo-mode is for...

can you force the processors to go slower by writing to sysfs?

eg. as root
cd /sys/devices/system/cpu/cpu0/cpufreq

cat scaling_max_freq
cat scaling_min_freq > scaling_max_freq
cat scaling_max_freq

and see if you can get that cpu to slow down, as shown by turbostat.
