IRQ Priority Boost

REGEDIT4

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\PriorityControl]
“IRQ8Priority”=dword:00000001

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\PriorityControl]
“IRQ8Priority”=dword:00000000

Note: Make sure your System CMOS/Real Time Clock are on IRQ 8

To get the actual IRQ# go to: Control Panel -> System -> Device Manager -> System Devices -> System CMOS/real time clock -> Properties -> Resources tab -> default IRQ# is 8 on all IBM PC clones.

Now you can add other IRQ’s for multiple entries, but real-time priority doesn’t like to share so if your going to, be aware of what your adding since the main tweak boosts almost all performance of your system.

You could boost your network card, or your video card if you wanted. Run msinfo32 to find the IRQ’s that you feel necessary to give this to.

NOTE: ALWAYS BACKUP YOUR REGISTRY BEFORE MAKING ANY CHANGES TO IT.
