Is there a reason to ever touch these voltages?

post #1 of 9
Thread Starter 
Is there any reason to touch these voltages in the bios? Or is it better to just leave them on [Auto] ?

IOH Voltage

IOH PCIE Voltage

ICH Voltage

ICH PCIE Voltage


If there is a reason someone would want to up these voltages, can you list them please?

The IOH and ICH voltages help with high end overclocking I.E above 4Ghz on your processor. If you're going with just 3.8 or something then set them to 1.2v

Broadly speaking, yes, but only for extreme stuff.

IOH voltage is northbridge voltage, and can help QPI frequency. ICH is southbridge (HDDs etc) which I would advise not to adjust.

Thanks guys, I didn't know if the PCIE voltages would affect overclocked SLi cards as far as a driver crash issue.

Not really, the voltages set on the card themselves would. I.E within MSI afterburner.

It would make it crash more if anything

You only need to mess with PCI-E voltages if the PCI bus is overclocked tbh.
