Card Slot Order MacPro Dual 3.0 Quad

[Touchwood Studios]

I have a Quad core Mac Pro with HD 3 Accel PCIe and Protools will not start up with more than the Core installed.
It appears that the card slot order is wrong. There is nothing in the installion guide of slot order for Mac Pro's
Protools Boots OK with just the core care but protools fails to start with any Accels cards installed.
The TDM cables are installed OK Port B on Core to Port A on the next Accel card etc.
Any hints would be great. Thanks

Probably bad flexcable, have you tried starting with cards seated but not connected ?

AFAIK, the core goes in slot 2 (whatever's nearest to the video card), the accel cards in 3 and 4. However, it may be a compatibility issue. I just ordered what I thought was a 2x2 3Gig MAc Pro and mistakenly I got a 2x4 (silly me!) This system reports hardware errors when my PCIe host card for my digi expansion chassis is put in. I've had to revert to a G5 whilst Digi (hopefully) produces a compatible PCIe host card for the 8-core machines.

Acoring to the Compability page the 3.0 Ghz Dual Processor Dual Core is qualified.
All the cards are seated OK.

I've just ordered a new Mac Pro and a HD2 system - Has the card order really changed from the G5 times? It used to be the other way around with Core on the furthest slot from the video card.

just had the same exact problem and it turned out to a bad accel card out of the box brand spanking new . just put in one card at a time to find out which one was bad
even the digitest application would crash till the card was removed

My bad - of course the Core goes there right after the video card...

I had the exact problem too. It was a bad Accel card.
