    In MSI mode the numbers we have in (#) change to (-#)

    Numbers showed in this window are not the keys. They are just presenting IRQ numbers in hexadecimal form.

    Why not to? I`d switched all that could be.

    Sata and nic are in this msi mode. Is reason to even do any this if one has no issues or problems

    Generic reasons like curiosity, feeling of implication, desire to achieve more... The same as with overclocking, game config-file tweaking...

    If you changed registry value MSISupported from 1 to 0, then you disabled MSI-mode for a device.

    hi guys this is a very interesting read, but i have one question, if every device i have has its own IRQ do i need this? will it provide any benefit?

    ok understood, now another question, if i enable this on the video card,will i need to do so on the pciexpress ports?

    My video card shares IRQ 16 with the x58 chipset hub and one PCIEX port. since they are sharing the same IRQ 16, my logic tells me i have to enable msi so to the 3 devices in total.

    is this correct?

    it has a nice and logical explanation, its dependencies are chipset, device and driver, wich makes a lot of sense, trying out something new never hurts, espcially if you get free performance and stability out of it.

    Now in the other hand, if your system provides the speed you crave, then just dont follow the guide. =)

    Im gonna test it myself, but since the data is here, and these great guys have been tweaking with the settings longer than me, then it doenst hurt to ask them so i can take out some problems out of the equation.

    Forums are just for that, sharing knowledge and saving time.

    I always crave more :p

    Anyways I'm going to give this ago when I have more time. Doesn't seem hard to do, but seems a bit of a pain in the ass ... when it doesn't work and gives you a BSOD.

    My 470 GTX isn't running in MSI for starters...

    I have switched PCI-X root ports to MSI-mode. To give you smart answer I don`t have info niether on relationship between PCI Express root ports and connected devices nor on root ports themselvs.

    Successfully changed my 470 GTX to MSI-mode. For some odd reason I booted a few seconds quicker could've just been an isolated fluke.

    Be aware that (NVidia) driver installer can revert device to line-mode. It did on my rig when I`ve installed 320.18.
