  • PCI card install order Question

    I got my new Asus A7S333 from FedEx and I have a question on installing PCI Cards. I've always put the sound card in the last slot then network card and so on so forth. I have a promise RAID card I got and I'm assuming the 2nd PCI slot would be the best place to install it. Any comments?

      Most existing single CPU mainboards use a standard PIC chip (Programmable Interrupt Controller). These cards have just four INT's: INTA, INTB, INTC & INTD. Since so few INT's are responsible for all 16 (0-15) interrupts some sharing is *almost* inevitable.

      Counting from the AGP:

      PCI #1 should be avoided for all but low bandwidth cards because it most often shares INTA with the AGP itself. The AGP can *theoretically* use up to 2 INT lines, but most often does not.

      PCI #2 is typically unshared and best for high bandwidth devices like a video editing card.

      PCI #3 most often shares an INT line with a 6th PCI slot, if any.

      PCI #4 and 5 most often share an INT line.

      The wisdom of putting a sound card in the last slot depends on the cards bandwidth, what is in the shared slot if any etc.

      Some PCI sound cards are still high PCI bandwidth operators (Audigy, SBLive etc.) while others use almost no resources when playing DirectSound (Turtle Beach Santa Cruz/VideoLogic Sonic Fury, Hercules Game Theater).

      Many newer mainboards are coming with the ability to use either PIC (legacy mode) or the newer APIC (Advanced Programmable Interrupt Controller) which can handle up to 256 interrupts

      When APIC is used (must be an NT kerneled OS) you can have >16 IRQ's, and those you use will work much faster than with a PIC chip.

      Rub: best to install the OS with both APIC and ACPI active in the BIOS so it'll configure itself properly. As such existing OS installs may work at first but become unstable after some time. Forcing an ESCD update may fix this, but 'tis better to start fresh.

      Time to dig through the BIOS section of the manual to see if you hit the jackpot

      FYI: the Gigabyte GA-7VRX and GA-7VRXP are both APIC boards.

      The only problem with the GA-7VRX has a problem with the Fasttrak TX4 but the Fasttrak100 works great.

      The GA-7VRXP has a Fasttrak100 controller onboard.

        Doc,

        Thanks for the info...the Asus A7S333 supports APIC and I was wondering what the hell it was...the manual doesnt tell you jackcrap on what it does, though I noticed that only my Video card and Promise controller where reported in the lower ICQ numbers during boot up when it was turned on.

              It's normally a case looking in the book and seeing which slot shares with which.

                As an addendum to what Doc Mordrid said: If you've have the USB controller enabled with and IRQ, it will share PCI 4,5 on your board.

                I've owned a ton of Gigabyte boards (My two of my machines are using them now), and just got a new one (You're not cleared for that one yet hehe...), and this has always been the case with them.

                  Thanks for that addendum MM. I should have included that tidbit, but was getting writers cramp

                  I'm on my first couple of Gigabytes; one GA-7VRX and one GA-7VRXP. Both are excellent save for the 7VRX's problem with the TX4.

                  The only other problem with them is VIA's making: poor PCI busmastering performance. This problem still haunts the cards that use their chipsets bigtime.

                    Normally ASUS lists the PCI IRQ settings in their manuals.. it will be a diagram where it will be indicated which device/slot is sharing an IRQ with another slot, normally if i am using a sound card. i would disable the onboard sound and use the slot it was sharing since it should now be free :P
