I hear different people saying different things about the "burn-in" procedure.

Some recomment running CPU at lowest possible MHZ at VCore+0.5 V to keep low temperatures for 12-24-48 hours (numbers differ). Say 500Mhz@2.2V
Others insist burn-in should be done with high voltage but default(stock) CPU settings. Like 133x14@2.2V overnight.
Third opinion is just run the CPU at highest acheavable speed, and it will be able to get faster over time.

There's also so called "inverse burn-in" saying take the CPU to maximum oc, take a small step backwards to known stable setting, then decrease the voltage til you get to the point it is not 100% stable, then run a stressing utility, then again after it fails and so on. People achieve good results (so they say).

I would like to hear any opinion about the way it should be done. (Taking aside the opinions telling why it shouldn't be done for other thread).

Thanks, Gil.

Well, i had some results after intensive burn in under cpu extreme temperature and load conditions (Prime95) overnight. Each time i do it (and i did it twice), i can increase the FSB in 3Mhz. I set the FSB to 140Mhz @ 1,75v and tested, after 30 minutes get an error. Two days pasted, i tried it again and it run 8h20m clean! Same thing with FSB 143Mhz@1,775Mhz. I don't know why, but i can compare it to my car motor. I get it from my father who use to drive slow. Whe he passed the car to me, it seemed the car "stucks" at high speeds but, now, two mounths passed, the car just flys...
