Dan3,

Re: "Athlon will overclock to 2.1GHZ with dry ice, and 2.2GHZ in LN2. P4 will
overclock to 3GHZ with dry ice, and (that stepping) overclocks to 3.8GHZ with LN2."

Facinating ... The P4 exhibits what I would expect from a CPU that
has speed limited by FET drive currents (IDsat). As temperature is
reduced, FET drive currents increase due to reduced "phonon scattering" of carriers.
Why doesn't the AthWiper respond the same way ... Could it be some
"architecture thingy" ?? Speed limited in a critical path by a "race condition"
rather than FET performance ?? Not a good thing, IMHO.

Make It So,
Yousef

Looks like Intel pulled a rabbit out of Bunny's hat.
