when i played a game and it was very slow
when opened cpuz
found clock speed at 800mhz
fsb at 200
and multiplier 4
what i tried
1_win7 give my cpu score ( 2 )
when it used to be 6.5
2_tried prime 95
clocks didnt increase

3_reset the cmos
doesnt work
4_disabled cool and quiet

5_power managment in windows set it to performance
doesnt work
6_updated bios doesnt work
7_downgraded bios doesnt work
8_updated bios again no luck
9_downloaded amd overdrive and tried to increase the multiplier
no luck still stuck at 4

until i found this

the cpu vid used to be 1.32
but now its 0.9750
and btw the cpu vid differ than the cpu core
now i think its psu issue
so what iam asking u guys

and read the cpu vid value
i think this value doesnt change even in idle

there's some kind of controller in the windows settings where you can underclock your processor and/or ram. i know this because there was a game where if you had more than 2 gigs of ram it didn't play, and i had to disable half of my available ram. lemme try and look it up

try manually setting the multiplier to the correct setting for your cpu if possible

Go into your bios and manually set the mutiplier. What motherboard do you have?

sounds like you may need to clear the CMOS.

 

[kar1zma89]

how to be sure that the cmos got cleared ???

i removed the battery

and in startup it showed cmos error

and let me choose between 1_default and 2_last known good

i choosed default


does that mean that i cleared the cmos
