    How can I reduce the Processor ratings Celeron M900 from 900Mhz to 600MHz

    feitosamarcos

      Hello for All, I'm a Engineer and I'm facing a problem.

       

      We have a DOS application runs since 1995, on the begin of this year the Siemens Company updated your PC477 to PC477B and the processor ratings increased from 600Mhz to 900 MHz and this is the problem, with this rating our application doesn't work.

       

      Is there a way to reduce the rating, Or something to do for the Processor 900MHz works likes 600 MHz.

       

      Note: I need to do something in DOS or in the BIOS.

       

      Thanks in advance.

       

      Marcos.

          Hi there,

           

          In general this would be called under-clocking I guess, that is to tweak the cpu frequency. However this is not always possible.

          At bios level this is totally dependent on the motherboard model.

          Some intel motherboard allows you to tweak the memory and the cpu frequency, however with some limitations though. Mostly high-end extreme boards will have this feature but not all boards.

           

          So if you do not see any option in the bios that allow you to modify the cpu frequency or memory frequency, then it is not a high end board that will allow this feature.

           

          Unfortunately at this level there are no application that will allow you to reduce the cpu frequency at bios level or even dos.. well ..  unless if somebody know how to do it with some low level programming. . I am not at this level yet... If there is any body out-there who can advise you of a better solution, i would be happy to know as well.

           

          Hope this will be useful.

           

          Cheers.

            There's software programs that you can use to slow the computer down like, Mo'Slo.  There is a program called Dosbox as well.
