PCI-X 133Mhz and 100Mhz Slots

[benixau]

In the PMG5 (1.8 & DP2.0) there are 3 PCI-X slots. One of them runs at 133Mhz and the other two run at 100Mhz.

After reading the documentation (linked from macosxhints.com) from apple i have a pdf picture of the part of the PCI-X documentation that should clear up which port is the 133Mhz one.

Enjoy all you high bandwith peoples

...what PCI cards would need 133 Mhz thouroughput?

[benixau]

maybe audio (uncompressed)
also video. not as in grafics cards but as in pro video cards. Uncompressed video can be rather large. It (PIC-X 133) has a max throughput of 100MB/s. Enough for alot of uncompressed video.

Also think fibre channel (for connecting to the XServe RAID). It needs about 1Gbps - suprise suprise - same as the max for the 133Mhz slot ......
