* The Pentium Overdrive Processor with MMX technology is equipped with an on-package voltage regulator, which adapts the 3.3V system voltage to 2.8V processor voltage.

** Some motherboards have a voltage regulator next to the CPU socket. These revisions can accommodate a regular Intel Pentium processor with MMX technology. To install the MMX processor use the jumper settings from the table above. The motherboard will automatically recognise the MMX processor and adjust the processor voltage. If the motherboard does not come with a voltage regulator on board, the system does not support the MMX processor!

Warning: INSTALLING AN MMX PROCESSOR ON A MOTHERBOARD THAT DOES NOT HAVE A VOLTAGE REGULATOR MAY CAUSE PERMANENT DAMAGE TO THE PROCESSOR!
