Hey mate, I have an Asus Striker II Extreme. Let me give you some advice, take PcProbe readings with a pinch of salt.
PcProbe was reporting my DDR3 voltage as 0.0v, then 2 seconds later, 3v! If this was correct I'd be getting bluscreens or even fried RAM modules, as 3volts would almost certainly kill them. Other programs such as motherboard monitor or HWmonitor, did not see these fluctuations in voltages. Also, PcProbe reported my Vcore to be 1.55, whilst in BIOS it was 1.4v.
Try other programs to "double check" the PcProbe readings. I've emailed Asus support regarding these errors, and they've simply replied to me "If your system is otherwise stable, and other programs are reporting correct voltages/temperatures, then do not worry".
If the readings are correct, then you might try what mame said. Wow, I've written a lot.
