I'm happy with that...

What Tony says is absolutely true! Mem controller in K10 is way better compared to K8. My Ballistix is working flawlessly with 2.25V @1000MHz 4-4-4 timings. On K8 it needed 2.42V and it wasn't completely stable ...

If increasing NB voltage will mitigate risk of breaking CPU with over 2.2VDIMM then it's OK and most affected are AM2+ board owners (due to 1.1V NB power plane).
