please I ask about my motherboard MV43V or here http://eu.shuttle.com/archive/en/mv... why it support CPU Intel Pentium 4 socket 478 2.66 GHz FSB 133 MHZ and it cannot support Intel Pentium 4 socket 478 2.66 GHz FSB100MHZ means when I check My CPU 2.66 GHz FSB100MHZ by CPU-Z or Everest programs ,I get wrong core speed ... 2000 MHZ not 2600 MHz http://hdishna.googlepages.com/7f83... Notice I get last Bios update MV43V007 and donnot fix this problem and I cannot know why my mother board cannot support this CPU 2.66 GHz FSB100MHZ in CPU Support List here http://eu.shuttle.com/archive/en/mv... or here http://www.cpu-upgrade.com/mb-Shutt... please help ....... thanks All [/url]

My guess is you're getting it backwards. There is no "CPU 2.66 GHz FSB100MHZ". You probably have a P4 2.66GHz/533MHz FSB CPU will *should* be clocked at 20 x 133MHz. However, you have to clocked at 20 x 100MHz, therefore it's running at 2.0GHz. All you have to do is change the CPU freq from 100MHz to 133MHz. This is either done in the BIOS or it *may* have to be done on the motherboard itself. Read your manual.

thanks Dear ,but there is CPU 2.66 GHz FSB100MHZ look here http://www.cpu-world.com/CPUs/Penti... - no chance for change in setup screen http://hdishna.googlepages.com/5815... No news in my motherboard manual ..here if you want to check it http://www.zshare.net/download/8260...

The CPU you linked to is 2600mhz, you have stated you have a 2666mhz which has a 133fsb Therefore what do you actually have ??

- Dear Bakers .. I have tow values in CPU-Z program and same with Everest program it,2.66 GHZ and core speed 2000MHZ and look here with Intel programs http://hdishna.googlepages.com/2856... ----------------- so sorry for Dear jam .... I reread the my motherboard website and manaul again .... look here about this question ?????http://eu.shuttle.com/archive/en/mv43_faq.htm -I have P4 2.4.GHz (533MHz) CPU installed, but why shows P4 1.8GHz on the screen? it's same my problem ... and the manual tell me more about this point http://hdishna.googlepages.com/1-9.JPG I will do it now , and tell you about the result .Mabye fine ,thanks all again

It appears that you have a 533MHz FSB (133MHz) CPU running at 400MHz FSB (100MHz). Here's what you should have: 20 x 133MHz = 2666MHz Here's what you apparently have: 20 x 100MHz = 2000MHz All you have to do is change the CPU frequency setting in the BIOS from 100 (or 400) to 133 (or 533). "I have P4 2.4.GHz (533MHz) CPU installed, but why shows P4 1.8GHz on the screen?" Yes, it is the same thing: 18 x 133MHz = 2400MHz 18 x 100MHz = 1800MHz

Dear Jam the bios screen is locked for any change but by set JP1A1 on the motherboard to pins 2-3 and JP1B1 to pins 1-2 to use a 133 FSB or 100 FSB as here http://hdishna.googlepages.com/1-9.JPG Tganks Jam ... thanks all my friends
