Question about Dual Card Setup (Dual 2.7 G5)

[Hisham Samawi]

I know this has been discussed but I just wanted to make sure that given my setup everything is as good as can be. I have 2 -UAD cards and a Lynx Two Audio Card. My current setup has the graphics card in the bottom slot, then the Lynx card on top then the two UAD cards in the top two slots. Does this mean they are on seperate busses? If someone knows a better combination of my cards that will give me better performance, please tell me. Or if mine is the right way to do it then please tell me for peace of mind. Still pissed about the whole bus issue, Can't wait until all my stuff works on the new macintels so i can switch and be done with it.

thanks

Not sure if this helps but it's all the info I could find at UAD.

your setup is on 2 busses
i have them at the 2 lower busses
an additional pci firewire card in the top (faster buss)

i also had your setup
works also
i do think it is a safer setup right now with the 2 on the same buss.
less buffer reruns in logic....

how do the new PCIe cards fit into the picture. Will they solve my problem or is it still a bus issue. How does PCIe work with PCIx?

They don't fit into the picture at all. The 2.7GHz G5 machines are PCI-X slots only. The new PCIe cards are not compatible with the motherboards on the 2.7 G5s and do nothing for them.

The problem is with the AMD chip on the PCI-x motherboard of the 2.7GHz machines and the best solution (if you have to use that machine like I do), is to put the cards in a Magma expansion chassie...which is not cheap.

UA website says:
There are different types of PCIe card slots, 1x, 4x, 8x, and 16x. What type is the UAD-1e and will it work in the other slots?
The UAD-1e is a 1x PCIe card, but it will fit in and work fine in any 4x, 8x, and 16x slot. Shipping G5s have two 4x, one 8x, and one 16x slot, and the UAD-1e will work in all three.

Shipping G5s have two 4x, one 8x, and one 16x slot, and the UAD-1e will work in all three.

But that does nothing for the original poster who has a dual 2.7 G5. Those machines have PCI-x motherboards and the UAD-1e cards are not compatible with the older G5 machines...which is what he is asking about. So the new cards released (which are the same DSP...just a different connector on the card) don't do anything for the original posters question.

I'm kinda lost now...I have a G5 2.7/Dual and I have the UAD card. It runs on my computer...but the number of plugins are reduced because of the 8131 config. on the Mac.

So what you are saying is the new PCIe card will not allow the 2.7/dual to run more UA plugins than with the older PCI card?

The 2.7 Dual G5 is not a PCI express machine. It has a regular, older PCI motherboard. The new UAD-1e cards are for computers with motherboards that have PCIexpress connectors only (Like all the new Intel and Dual Core MACs being sold).

The UAD-1e card will not physically fit in your 2.7 G5 motherboard. Therefor it is not an issue.

Secondly...it is not a new card...it is the same card with a different connector on it. So there is no more or less DSP power on the new card than the one you already have now.

The problem you have now with the AMD chip is on the motherboard of your 2.7 computer and can not be changed.
