    Technocd got a reaction from oskarha in [GUIDE] LGA 771 Mod for Dell Vostro 220(s)   
    More informations + Backup Upload 
     
    BIOS 1.2.0
    Dont need to disable Speedstep or C1E support. 
    Only disable C-STATE.

    Tested and Working on Dell Vostro 220 + Xeon E5450 Overclocked with SetFSB PLL 
    Using :
    CV184-2APAG (NEC Express5800 S70 Type FL)
     
    3.3GHz
     
    Note if you Overclock with SetFSB you will need to change some settings in Windows using Windows administrator command prompt
     
    bcdedit /set useplatformclock yes
    bcdedit /set tscsyncpolicy Enhanced
    bcdedit /set disabledynamictick yes
     
    These will set things back to default if your system doesn't like them...
     
    bcdedit /set useplatformclock no
    bcdedit /set tscsyncpolicy Default
    bcdedit /set disabledynamictick no
    You will need to reboot after any bcdedit.
     
    A tiny program called WinTimerTester will show QueryPerformanceFreq 14.31818 MHz
    Run it for 300 seconds you will see Ratio value QueryPerformanceFreq/GetTickCount to reach 1

    This SetFSB overclock method will ensure that the PC clock remains functioning normally
