Magma Expressbox7 EB7 Which one? Gen I or II
Hi
Not enough DSP, so I am looking for a used PCIe Expansion Chassis so I can get more HD PCIe Accel cards. I have a 12 Core MacPro (2010). It looks like the Magma Expressbox 7 is the way to go. I see there are 2 different generations of the EB7, Gen I and Gen II. All I am seeing for sale in the used market is the Gen I, is there any real need or upside to the Gen II version? The Gen II is double the throughput, but does an HD5 PCIe card system need that, or when would it be needed? Also, I can't find any compatibility information on Expansions Chassis and ProTools 10 in Avid support. . . does anyone know the link to that info? Avid article on the EB7: http://avid.force.com/pkb/articles/e...-II&popup=true I would have gone HDX a long time ago, but Avid did not bother to support the blue faced 192s and WAVES has not done AAX DSP either, so it seems me, and everyone else I know that already had HD3, is sticking to ProTools 10 with the old cards. I bet if all the math was revealed, AVID is actually loosing business revenue by their planned obsolescence strategy, but that is another topic all together. Please advise is anyone knows more about which Magma EB7 I can/should use, and any other associated caveats related to moving the cards out of the MacPro and into an expansion chassis. Thanks!

Re: Magma Expressbox7 EB7 Which one? Gen I or II
I think both are approved, Video & GCI both need higher bandwidth than Audio
the other related links seem MC related To your other point, there were functions that were not doable in the old architecture and the old chips were End of Life/no further development Parts manufactures discontinue parts lines regularly, I will not bore you with the hell I went through looking for an old Dolby PL Decoder chip for a system that needed it (it was cheaper than redoing the whole room but but it was a major PITA)

Re: Magma Expressbox7 EB7 Which one? Gen I or II
The EB-7 is indeed the way to go. I got one about 9 months ago and am running it in my MacPro 1,1 with 7 cards. It is awesome.
I seem to remember reading something about the Gen II not being qualified for HDX but since you will be sticking with TDM I dont think it will matter. There is absolutely no reason to wait around for a Gen II box as the Gen I is much, much more common and also fully supported by AVID. There are two potential caveats I should make you aware of:
I used to have a ton of unexplainable, intermittent Kernel Panics when running HD7. The crux was that all cards alwyas passed DigiTest which only tests the funcionality of all the chips. However, problems started arising when the chips were under load as they draw considerably more power then. Because of the way each mix is evolving different chips on different cards will be allocated even if you are failry consitent as far as track count/voice allocation and plug-in usage is concerned. That means erratic behaviour is very difficult to pinpoint. A bad PSU can screw things up in more ways than one so if you buy a chassis and start having issues this should be your fisrt port of call. I recently spent some long and very painful hours troubleshooting my system until a member on this forum pointed me towards the PSU as a possible cause (I should use this opportunity to thank Bob Nagy again for doing so). Once I swapped out the PSU all of these problems went away. It is very easy to do only takes about half an hour. Regarding the fan: I bought this one which is absolutely brilliant and not very expensive at all. I would definitely get an EB7. It works very well and prices for Accel cards are very low right now. I am surprised there aren't more people buying them at this point.

Re: Magma Expressbox7 EB7 Which one? Gen I or II
Yes it does. It is fully supported / qualified by Avid.

I suppose the thing to check is whether this is a common problem or whether it is unique to you. Also, is this something that's a recent development on a system that was fine before? I wouldn't have thought that certain plug-ins cause the chips to have more of a power draw than others (when taking the same amount of DSP). Maybe try running a test session without using TDM and see if it happens on purely native sessions as well.

Re: Magma Expressbox7 EB7 Which one? Gen I or II
Wow, that's great news. So your able to use all those chips.
9x7=63 total chips for 7 cards? right? Or does it let you just use 6 cards with chips and the 7th card for inputs? Thanks, Marc

However, some plug-ins take more DSP depending on which chip they are instanciated on. That is the same for all TDM rigs though, regardless of the number of cards you have.

I think I'm going this route for my mix setup. I use Logic Pro for music anyway but, having more cards would make the mixing process easier/quicker. I really appreciate this info, Marc
