uhh im not an expert or close to but from wat i know wen amd makes a chip they kinda set it to work about 80% so the life last long and its not straining it. Overclocking is kinda making it go up so working 90% 95% or something like that so you egt more performance but you are pushing it harder.So it applies to everythign , it kinda just makes it work a lil more percent
