Voltage Spikes (Asus P8P67 Deluxe)


Recommended Posts

Hello Everyone, I have been wondering why I get these random voltage spikes. They sometimes come in bursts or intermitently. I thought they were a result of overclocking but they also happen when the pc sits idle. Sometimes they don't happen at all either overclocking or sitting idle. I keep thinking it might be my psu which is a new Corsair AX750 bought in January with my Sandy Bridge i7 2600k cpu and Asus P8P67 Deluxe motherboard. Do you think its my psu and if so how would I confirm it for RMA with Corsair?

Thanks and Have A Great Day!

I think those spikes are most likely because of the sensor chip providing instable values. In case your PSU would provide such unstable values at cases, your system should sometimes lock up.

BTW, 5.6V for the +5V rail seems a bit high. Do you use an old AIDA64 version that does not fully support your motherboard? Or your PSU really puts out 5.6V?

Thanks for your reply! Yes what you said makes sense,I've noticed the bios voltages were always more like 5.05-5.10 and yes I should upate to the lastest version. Do I have to uninstall first and then reinstall the update?

No need to do that. Just download the latest beta ZIP package, and extract the ZIP contents straight into the installation folder of AIDA64. Let it overwrite any existing files. Your old configuration settings will be retained.

Latest AIDA64 beta is available at:
