No can tell if it will but you are much more likely to see it suddenly die if you keep them that high. Might last 1 week, might last 2 years but the question to ask yourself is: would it be ok if it died tomorrow?I'm not really concerned about reduced life time as long it'll survive till sometime next year
Get it to 1.5V or less as a start. You will have to drop the Ghz as a result.So basically i should turn it down to what voltage?
