underclock and undervolt

If I’m not mistake only hobbyist level motherboards let you control the voltages and if one knows enough to get one of those they probably don’t need the advice I gave.

Also it’s hard to end up with a non-working or unstable configuration with underclocking, whilst it’s pretty easy to do so with undervoltage.

That said, for those who know what they’re doing, your suggestion definitely delivers lowers temperatures than underclocking alone though at the risk of a less stable system (which can be ameliorated with proper stress testing).
