Boost the Speed of most Apple G3 Systems or Upgrades!
Full OSX Compatiblity with all Single CPU Upgrades... including Tiger!
Exclusive Feedback and
Live CPU/Cache Testing!

Work Faster
and Safer!
The Award Wining CPU Control Software, MAChSpeed Control - has been updated for Tiger and includes a range of new features!

As always, it provides performance and compatibility tools for Mac CPUs. Its features include configuration, testing and reporting of the CPU and Caches. MAChSpeed Control supports all single processor G3/G4/G5 Apple Systems and CPU Upgrades, in OS 9 and OS X with 100% assured compatibility and performance.


  • System tuning. Works around a variety of processor errors in early G3 and G4 CPUs
  • System Information. Ensure accurate CPU details in Apple System Profiler, and Applications
  • Advanced AltiVec Support. True across-the board compatibility with AltiVec applications.
  • CPU Startup Speed Management. Available on 750 FX/GX CPUs.
  • System 9 through Mac OS 10.4. Supports, by far, the widest range of CPUs available.
  • Reset Mode. Allows the user to reset to defaults, if the CPU/cache fail at high speed.
  • Improved XPOSTFACTO support. Extends compatibility to older systems with OSX installed.


  • Improved Memory / Cache Performance. Uses faster settings to maximize performance.
  • Semi-automatic Cache. Allows user to choose from tested “safe” speeds.
  • Dynamic CPU Speed Switching. Available on 750 FX/GX CPUs as found in the iBook G3 and on high-speed G3 upgrades. This feature aChange the CPU speed on the fly via software (750 fx/gx only).

Testing And Reporting:

  • Automatic CPU/Cache Profiling. Exclusive system profiling and initialization at startup.
  • Factory Retest on Restart. Allows the utility to re-profile and test the cache on every restart.
  • Active CPU/Cache Test. When opened, the utility performs a looping CPU/Caches/RAM test.
  • Dynamic Status Information. Provides real-time updates of speed, CPU, and caches.
  • Thermal Monitoring. Will alert you if overheating occurs (750 - 7410 CPUs only).
  • Memory. A memory overview (with optimization) is available on Beige G3 and earlier machines.

Simply install and reboot. The smart cache features test your CPU and stabilize your system immediately. Checking statistics is just a click away. Open the interface to perform an active test, check settings, change Cache configuration or check RAM. Note: Does not support dual CPUs.

Auto Profiling & Protection Technology: Automated compatibility and performance software that provides full cache and CPU profiling for additional combined CPU and cache speed - without the risk.

Smart Recovery: The software will lower the cache speed when it detects a cache system crash. Also includes a unique safe-boot CPU reset feature.

Processor Software Adjustment: Many newer CPU upgrades aren't identified correctly in Apple System Profiler, creating Apple software issues. MAChSpeed Control allows Apple System Profiler to see the true CPU type and speed.

Extended CPU/Cache Testing: MAChSpeed Control is a factory burn-in and testing appication with an additional 're-profile and test on restart' function. Great for isolating CPU/cache issues.
