Best Burn in Methods...

[gangstawrapper]

I've heard conflicting advice for burn in methods. Some people say run the cpu at default speed and voltage for a period of time while others say that you should run the cpu at the highest speed/lowest voltage that it is stable at and continually lower the voltage. What does everybody else do? Advice please! My 2.4/2.5v 366@550 is melting the case...

Cool It!

Nothing I have learned about microelectronics has ever confirmed anything about the concept of "burning in" a semiconductor device. The concept of electromigration is a proven adversary of lifespan. It only can be accelerated by increased temperature.

Sure, a new internal combustion engine might benefit from ring-seating sprints, but there is no analog in molecular structures.

Hey Roy: Properly followed "burn in" procedures do work. My P2-450 would not boot at 504 MHz out of the box and now it runs stable at 527 MHz @ 2.0 volts and even 558 MHz @ 2.2 volts when the room temp is cool enough. All of this while the CPU is at 100% load running the RC5 client software, not while at idle!!!

The same process let me get my Celeron 300A stable at 464 MHz @ 2.0 volts and 504 MHz @ 2.2 volts when the room is cool enough.

I dunno if burning works, but i can run a 504 2.2volts after i burned it in at 2.3 for a week with seti@home.before i burned it in it would freeze on win splash screen.

But hey, bees arent supposed to be able to fly either

My dad does environmental testing on electronics for military aviation.
If burning-in means running RC5 for a couple of days, you are letting your CPUs off too lightly!

Try putting it in a pressure chamber, varying the temperature between -60C and 120C, and throwing solvents and steam at it (the kinda stuff that leaks from an airplane with bullet holes in it). While it's running.

Oh yeah, then you zap it with a big f***-off electromagnetic pulse. And some static.

I guess if you are flying combat missions, you don't want your fly-by-wire to disappear if your CPU fan cuts out [img]/forum/smile.gif[/img]
I wonder if they are overclocking...

Yeah U-96?
Well my dad is Bill Clinton and he works his so hard that they all GO DOWN in minutes...

Chelsea Clinton? On this board?

PS I liked the bit in the film where you kicked Butthead out of your window. That was cool. Uhuhuhuhuh!

tee hee (in a girlish voice; with absolutely no sexual undertones)

Seriously, In the time this thread has been active my 366@550 has now become stable at 2.4v....

We all know 366's overclock well but hey 2.4 and 2.5 volts will melt u chip if you arn't carefull
