Thermal Specifications

GCC Optimization Flags

You should use the following if you have a Mobile Pentium III:

-Os -march=pentium3 -fomit-frame-pointer -pipe

Enable L2 cache

When using a Pentium III MMC2 module in 600E, one needs to activate the L2 cache with the help of a kernel module. See also this post


FOOTNOTES [Δ]
  1. SpeedStep was introduced with the 600 MHz models, the 400, 450 and 500 MHz Coppermine models didn't feature SpeedStep.
  2. Maximum Thermal Design Power as per Mobile Pentium III data sheet. Typical Thermal Design Power values are about 60% of maximum.
