[b]How to boost XP speed by by changing real time clock priority?[/b] I read about this trick the other day over Internet. Open Registry by going to START-RUN and typing REGEDIT. Navigate to [b][HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\PriorityControl]. If you see an entry by the name IRQ8Priority set it to a value "IRQ8Priority"=dword:00000001[/b] if you don't then click on the right pane and add a new dword entry with given name.. IRQ8 is typically reserved for real time clock in most of the computers. Make sure thats the case (by going to device manager -> system devices -> system COMS/realtime clock -> properties -> resources tab , if it is set to another number try adding an entry with that number N as IRQNPriority) . Generally realtime clock priority boosting helps most but you are free to try others as well. [i]IMPORTANT DISCLAIMER: Before doing anything with registry, It is very important that you take a backup of registry by exporting it. Remember even a minor mistake in registry could render your system unusable or will cause it to stop or crash. XPTOOLS is not responsible for any such damage that may occur directly or indirectly as a result of your applying these changes. Don't try it if you are not sure. Use at your own risk.[/i]
