###is it possible to upgrade a pci slot to pci-x###

[minkis]

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.

oh ok so would i be ok on the major technology changes for awhile if i got a single 1.8ghz

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...If the systemboard supports PCI-X mode operation for a bridge, then a pullup resistor to VDD33 must be placed on the bridge’s PCIXCAP pin. To limit the frequency of a PCI-X-capable bridge to 66 MHz on a systemboard, the systemboard must also include a pulldown resistor from the bridge’s PCIXCAP pin to ground. The strapping options on GNT[4:3]# are used to distinguish between systems that support 100MHz and 133 MHz; in either of these two cases, the system board should include no pulldown resistors on PCIXCAP.

yea for the most part, i have an ibook up in classifieds and it's already gotten over 1150 to look at it and it only been up about a week or so

[minkis]

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.

oh yea i forgot to post that i just got a single 1.8 so i guess it doesn't matter anymore. thanks

So your sig needs some changing?

[minkis]

how about that
