AX8 PCI speeds and width

Can anyone tell me please the speeds and data width the "Abit AX8 Skt-939
PCIEx16 integrated Sound/GLAN/Firewire" m/board's legacy standard PCI
supports?

The background to this question is: I am looking for a m/board with PCI-X
(or at least fast PCI) to support an Adaptec 29320-R SCSI controller (or
even a 29160 card that I have). My supplier listed the "Abit AX8 Skt-939
PCIEx16 integrated Sound/GLAN/Firewire" as meeting my needs but I can find
no statement on the Abit site or in the manual that I downloaded of what
speeds the legacy PCI bus slots support or what data-width (32 or 64 bit).
I saw that
the PCI speed was adjustable in the BIOS but no actual values were listed.

Many thanks,
Iain.

Standard PCI is 133MBps.

If I'm not mistaken the PCI bus is 32bits. PCI-X is 64 bit. You can use
some PCI-X cards in a standard PCI slot but the bandwidth is severely
limited. Search for "pci bandwidth" for complete details.

Wes,

Thanks for your help. 133MHz was what I expected, but I was concerned
that it might be lower: to show PCI-e in a better light - since PCI-e is
what is being pushed nowadays (for good reasons I know, but I have a lot
of investment in good quality legacy SCSI kit that I want to get more life
from yet).

Cheers,
Iain.

It's not 133MHz, it's 133MBps @33MHz. Using a PCI-X card in a standard PCI
slot severely limits it's bandwidth.

Thanks for pointing out my mistake - could have been costly for me (I saw
what I wanted to see, not what had been written! :-)
