The problem is that I canīt get more than 48 track playback (@24 bit / @44.1 kHz) on the following system:
G3 350 Blue/White (latest firmware)
MacOS 8.6 (Swedish)
ATTO Dualchannel Exress PCI (firmware 1.44)
Protools 4.3.2 with DAE 3.4.f9
SBS Bit3 13-slot chassi
1 x Mix core and 4 Mix farms
1 x Twin Turbo 8 MB graphicscard
Iīve tried to take out 1 of the graphicscards but no joy. Tried all the folloing below.
Troubleshooting:
Doublechecked all Control Panel settings:
Colors at 256 (and greyscale) - helped to get 4-8 channels more
Disk Cache at 128k (also tried 512, 256k)
DAE Playback buffer set at 2, (4 and 8 also)
Removed ALL ATI Extensions (ATI Driver Update is reportedly notorious for PCI bandwidth hogging. Helped somewhat)
Trashed ALL prefs for PT
Tried different cardorder in the G3
The following tried on the ExpressPro-Tools software:
-Sync Rate set to 20/10. - Done (works better at 40/20)
-Termination set to Automatic. - Done
-PCI burst rate to 32. - Done (Works better at 512)
-Enable synchronous transfer. - Done
-Enable wide transfers. - Done
-Enable allow disconnect. - Done
-Enable LUN's Enabled. - Done
-Inhibit driver loading can be left disabled. - Done
-PCI Burst length should be set to match Pro Tools cards: 32 bytes. DSI 5.01 changes the burst length to 32 bytes on boot. This occurs only with the ATTO EPCI-DC card. Adaptec cards often spike with a large initial burst rate causing a -6042 error. - I didnīt notice any different between Adaptec 3940 and ATTO dual channel UW with the same setup. I first had a 3940 and I have bought a ATTO to try it out - No change!!!!
The following cardorder is used (tried minor variations with no luck):
The system is as follows:
G3 B/W card order
Slot 1 - Original graphics card
Slot 2 - PCI chassi host card
Slot 3 - ATTO card
Slot 4 - Extra graphics card (Twin Turbo 8MB)
PCI chassi card order (Bit 3 13-slot)
Slot 0 - Host chassi card
Slot 1 - Empty (as it states in Digi expansion chassi guide)
Slot 2 - Mix Core
Slot 3 - Mix farm 1
Slot 4 - Mix farm 2
Slot 5 - Mix farm 3
Slot 6 - Mix farm 4
I have replaced the following parts during a 5 month period (some improvments thou):
PM 9600/250 -> B/W G3/450
ATI Orion 128 (16 MB) -> Twin Turbo (8 MB)
2 x 9GB Seagate Barracuda -> 2 x 18GB Seagate Cheeta
Adaptec 3940 -> ATTO Dualchannel
Iīm going to try a Magma or Digi 7-slot chassi next week. Also going to try with Protools 5.01 just for the sake of it.
Is it more demanding for the PCI-bus to play back recorded tracks than to record them? I do not get any -6042 errors when recording 64 tracks at the same time but I can only playback 48 at the same time. Can someone at Digi please answer me!
In the studio I work during the days we have an almost identical setup with the exception that we use a beige (classic) G3/266 and a Bit 3 7-slot chassi and Adaptec 2940. We get the -6042 error about once every three month.
