This tweak can increase the priority given to any IRQ number, improving the performance of that component. The most common component this tweak is used for is the System CMOS/real time clock, which improves performance across the board go to : HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PriorityControl in the right hand pane create a new DWORD name it IRQ8Priority double click it and and put a 1 in the decimal box will look like this > IRQ8Priority REG_DWORD 0x00000001 (1) Reboot for it to take affect .Labels: irq priority perfomance, perfomance |
Of course, this tweak is good one to improve the I/O performance of the system. If we have to give priority to any other component the IRQ numbers can be found by typing msinfo32.exe in the run window.
Start>Run> type msinfo32.exe. Expand the Hardware Resorces tab and click on IRQs.
