how to do cpu burn in?
and what "exactly" that means ?
is it some way to make the cpu more freindly with higher speeds?

i asked the same question a few days ago. from what i've heard, nobody can explain why it works and quite possibly (for most people) it does not work. i'm not sure. one thing is certain, a burn-in period will help you to determine the stability of your overclock. it may also allow you to overclock your cpu higher and/or lower core voltages.

what you do is let your system work hard when you are not using it...like when you're sleeping. the popular programs i've seen are prime95, sisoft sandra, seti program, and the protein folding program. usually, a couple of these are run simultaneously.

i was a bit skeptical and still am..but i've been burning in my cpu every night. when i first got my 1.33, i could not get into windows above 150mhz and prime95 would report a rounding error and halt at 150fsb. in addition, my cpu was hitting 45C when i dropped the fsb back and ran my burn programs. i'm now at 152fsb and my core is only at 34C and prime95 is running fine. kinda incredible really. i'm certain i'm doing something differently, but then i'm the eternal skeptic. =) i'll try stepping it up again soon and i'll be adding watercooling soon. here's to hoping for 1.6!

just a benchmark screenie for ya.

Another issue with burn-in is fragile components. i.e. with new electronics (of almost any type) the components are most likely to fail soon after first being powered up or years later.

So some people believe when you get a new computer it is best to push it hard at first to weed out the components which will die early in life. This enables you to return legitimately defective components before the all too short warranty period expires. This is why many OEMs advertise 48hr or 72hr burn-in, they want to only sell a product and send it to you once.
