Burning in CPU ?

[NialM]

Is it true that you can get higher and more stable O/C results after the CPU has been "burned in" ? If so, how much of a differance does it make and how long does it take to get there ? Is this equally true for Intel and AMD ?

I've heard rumors of overclocking through "burn-in" methods. But as far as I know it is just a rumor.

In my experience, burning in has never accomplished much, except to check whether or not you are stable at a given speed.

So if my TB 1000c can only do 1400@10x140 now (2 weeks old) than thats it ?

Not really. The supposed point of burn ins is to get the overclocked component used to the stress, and then push it higher. Then rinse and repeat.

Are you dissapointed to only get 40% clock rise and 40% memory bandwidt increase? I'd say that was a pretty successful oc... ;o)

What sort of temps are you running at with that, and what heatsink, what voltage and what mobo?

Using Super mini orb (yes...I know !) Don't know bout the temp yet....I just know that it will hang @ 141+ after a few min. I am @ work now but it is running @ home at 140. Will have to check MBM when I am off this morning.

I didn't change the volt. What is the "norm" voltage ? What is the max I should set it at ?

default voltage is either 1.65 or 1.75, the lower I think.

The A7V133 will take it up to 1.85V which helps with stability but also generates a lot of heat.

My 1.33 runs 1.85V to give 11x142 (1563Mhz) totally stable.

So....If I am NOT o/c'ing, and my volt was set to 1.85 and I was running hot, I could lower the voltage and thus run cooler ? When I was running 1000@7.5x133, I idle @ 49c

Yep - but on an A7V133 if you haven't changed it the voltage is set to auto, which means the CPU is getting only what it needs (well, what AMD set it to ask for) Possibly it would run a little lower?

Hmmmmmmm...... I wonder why my little 1000 needs that much Volt ???

The default voltage on my T-Bird-C 1GHz was 1.75V.
