Anyone UNDERCLOCKING their Athlon Mobiles?

[BDSM]

Just wondering if anyone has tried how low voltage these puppies will accept at about 1-1,2 ghz.. Cuz I have a T-bred 1700+ running rock stable at 1.2 ghz @ 1.21 V actual. I don't care much for speed, I just want a cpu that generates as little heat as possible cuz I have my puter in a very confined aread (closet sorta) to make it nosieless.

So.. anyone know.. or wanna try? I'd buy one and try. But I won't. not cuz of the cost.. but because if it's worse than my t-bred heat wise it will be a big hassle for nothing.

I run it at stock, just diff FSB (195Mhz), that's rare enough

You do realize that the mobile Bartons are made to run at lower voltages, don't you? And since they are all Bartons, they have a larger die, which means they dissipate heat better. I would think that you could cool a mobile 2400, running at it's normal speed (roughly 1.77ghz) with exactly the same cooling setup you are using to cool your XP1700@1.2ghz.

i don't think this theory is true, my barton at 1.833ghz ran 54deg with the same hsf that my duron@2ghz uses and the duron only runs at 47C under load

the extra cache increases the surface area that the heat is dissipated off of, so you actually run hotter, cause that extra die space dissipates the same amount of heat per unit area as a small die does, more surface area with the same number of layers = more heat output per chip

exactly, i think there is an article about this at overclockers.com
