My p4 as been running at 3.00 ghz as that is the speed of the processor i built the machine my self and as been fine but recentley when i boot it the speed says its set to 1.50ghz I looked in cmos and highest it lets me change it to is 1.89ghz and thats no where near the 3.0. It should auto detetct the speed as that option as always been locked to change the speed. I spoke to computer shop where i got parts from last year he said check jummpers on the board the only ones i can find are the cmos reset and bios write protect. I also rested it and updated the bios but it still runs at 1.50 or 1.89 if i change it.
where is that option in bios. standard cmos advanced bios advanced chipset features integrated peripheals power mangement pnp/pci setup frequencey/ voltage control
abit sg72 mb but on the site all the bios in frequencey/ voltage control is displayed completely differentley. p4 3.0 ghz earlier when a turned it on it had changed to the correct speed automaticly like it should be doing but when a shut down and turned on again now its back to 1.50 100*15 1.50ghz or somat but earlier staed 200 *15 3ghz or soamt a had't changed anything in bios either a got the latest firmware
in your bios under frequency/voltage control, what is the cpu clock ratio & cpu frequency?? ratio might be 30 or 22.5 if cpu frequency is 100 or 133.
This is the options and default settings. Clock control by auto Cpu frquencey 200 Dram ratio spd async asp,pci,src, disabled if you change clock comtrol by user you can change cpu frequencey to 253 dram ratio to 1:1, 3:4, 3:5, 1:2, SPd async asp,pci,src, enabeld or dissbaled no option for cpu clock ratio
change clock control from auto to manual or to a number like 30 or 22.5. see if cpu frequency changes to 100 or 133. i had downloaded your manual & that is what it shows.
what is the bios update date & version because your bios cpu frequency configuration is showing different from manual.
Its the latest one but when a install the origonal that voltage control screen stays wiv same options but at one time it was the same as the manual
ok earlyer when a turned on it displayed corectly a had't changed anything and ran this cpu program in warning displaying this. when a went to rugby a shut down turned on wen a got home a had gone bk to 150 ran tht program again and displayed this.
its already set to 200 a have't changed anything every now and then iut boots at the correct speed but 9 times out of 10 it will detect a 1.50 ghz
