OC and Undervolting

[TheawesomeMCB]

So this has probably been asked lots and lots of times but it's still not fully clear to me.
Does overclocking and/or undervolting (Setting power limit and clocks in msi afterburner) Void warranty. I usually try to stay away from these settings but I want to experiment. I just don't want to void any warranty in the end.

no, there's no way to detect if a card has been through oc or downvolt whatsoever

 

if you flash a custom bios you lose it but within original bios settings you can do whatever you want
