    i am considering getting a power mac g5 and i'm hearing about how the new video cards will be pci-x instead of just pci and i don'thave the money to get a dual 2.0 or 2.5 so i was wondering ifi could just get a single 1.8 and add or convert my pci slots into pci-x slots. thanks

    oh yea and if you have a powermac g5 you are willing to let go you can post that too. thanks

    First of all, no you cannot upgrade a PCI slot to PCI-X.

    Secondly, the powermacs do not use the PCI-X slots for their graphics cards, they use an AGP slot. AGP slots are currently being phased out for PCI Express (PCIe for shot) not PCI-X, which is entirely different.

    All depends on the motherboard you have, the Rev. A PowerMac G5s used the same motherboard as the PCI-X PowerMacs -- which means they do have a PCI-X HT Tunnel, it's just crippled to run at PCI speed.

    Could be a resistor setting or a firmware setting, don't know.

    But it's rather like the PowerBooks vs. iBooks and the Pro-machine having spanning and the consumer doesn't even though it's the same chipset, and sometimes even the same graphics chip.

    ---

    The Rev. B machines don't use the same motherboard -- they don't have a PCI-X HT Tunnel and use the PCI bus on the KeyLargo 2 chip.

    The SP Rev. B machine uses the iMac G5 board -- so likewise no way there.

    ---

    On the Rev A machine you'll need to find out who made the PCI-X HT Tunnel and how to convert it from PCI to PCI-X speed, if it's an AMD-8131 chip...

    There is no physical difference in the slot, the SP PM 1.6 even has a PCI-X HT Tunnel, it just operates at PCI speed locking out the 100/133MHz PCI-X speeds.

    The on-line .pdf for the AMD-8131 has a chapter on how to configure the PCI-X HT Tunnel...

    The annoying symbols could be the reason nobody is replying, even with the constant price drops, bumps, etc...

    i never said it didn't get replies youre probaly looking at the one the is open, the one i'm talking about is closed but it had a little over 20 and the reason the price droped is b/c i might be able to make up the deffisat. and if the symbols don't work, what brought you here.
