Intel Celeron M

The Celeron M is a budget processor based on the Pentium M. Compared to the Pentium M it has only half the L2-Cache and lacks the SpeedStep feature (excl. Banias family).

Features

  • 800-1600 MHz tact
  • 400 MHz FSB (Supports 533 MHz with CPU-Pin Hack and DDR2,see this This puts the Clock speed in the 1066-2130 MHz range. Tested with a 370 Dothan)
  • 170 Million Transistors
  • 0.13µm or 0.09µm fabrication process
  • 512 KB or 1 MB L2-Cache
  • QuickStart, Deeper Sleep
  • MMX, SSE, SSE2 instruction sets

Thermal Specifications

The max. Core Temperature is 100°C.

GCC 3.3 Optimization Flags

CHOST="i686-pc-linux-gnu" CFLAGS="-march=pentium3 -msse2 -O2 -pipe -fomit-frame-pointer" CXXFLAGS="${CFLAGS}"


GCC 3.4 and Later

CHOST="i686-pc-linux-gnu" CFLAGS="-O2 -march=pentium-m -pipe -fomit-frame-pointer" CXXFLAGS="${CFLAGS}"

Someone can expirence problems with GCC 3.4.5 The solution can be

CFLAGS="-mcpu=i686 -O3 -pipe"


Speed Step

For using the speed step with the celeron M you must add the module p4-clockmod.

Kernel Options

When compiling the kernel choose the pentium-M processot type
