In my ongoing quest to get this 3 x RME card/4 UAD-1 card DAw happening
without the occasional crash or crackling in the audio, I am experimenting
with 2nd Magma chassis (a 7 slot unit) All of my UAD-1 cards are in the 13
slot chassis and all occupy IRQ 19 with the host card in mobo PCI slot #4. I
have been able to get my two HDSP 9652's on IRQ 17 & 18 by putting them in
the 7 slot Magma with the host card in mobo PCI slot #3.
Adding the Multiface PCI card to this chassis scrambles the IRQ assignments
to the point that either one of the HDSP RME cards is on IRQ 16 with the
video card and/or one of the cards is sharing an IREQ with the UAD-1
cards............both bad scenarios. However, putting both HDSP cards in
slots 1 & 2 of the 7 slot Magma and my Multiface PCI in slot #2 of the mobo
has allowed the RME cards to live on IRQ's 17 and 18, the UAD-1 cards to
occupy IRQ 19 and the video card to occupy IRQ 16. The DAW has been running
for over an hour in playback mode without crashing. Tomorrow I'll be
stressing it big time to see if the crackling in the audio is resolved. If
I'm successful, I'll have pushed this system about as far as this
architecture can go I think.
Though it appears that the 7 slot Magma may have solved my problem, in a way
it's sort of disappointing. I was expecting a friendlier IRQ assignment
scenario. I recently sold a 7 slot SBS chassis because after getting the 13
slot Magma and having good luck with it, I figured the Magma's were just a
better product. Now I have my doubts. I think the 7 slot SBS chassis was at
least as friendly as the 7 slot Magma, and perhaps moreso. My previous
experience with the SBS leads me to believe that I might have been more
successful with it in my current scenario than with the Magma.
Anyway.......it's hard to say and if my testing tomorrow goes well, I'll be
settling into mix mode. I've got a lot to do here.
I do have another dual core CPU and video card on order right now and a
Gigabye NForce 3 mobo. This mobo is also supposed to be friendly with UAD-1
cards. I'll probably be building another system with this. For what exactly,
I'm not quite sure If my crurrent system is stable tomorrow, I'll be
leaving it be, most likely..........yeah.......right!!!......Hey.......if
someone wants to loan me an EDS card, 442 aand C-16, I might bench this
thing and see if I can get Paris working with a dual core CPU.
That might be a worth while experiment.
