.pro loading problems on SCOPE/SP 24 ADAT

[kempfpe]

Hello,

can anyone help me with my serious problem:

I´ve upgraded my SCOPE/SP 4.0 (ADAT 24) System from a P4-Computer (ASUS P4T-533C with AGP-Graphic-Card, Windows XP SP2)
to a Quad Core Q9400 on ASUS P5Q Pro with PCIe Graphic-Card ATI Radeon HD 4670. No other PCI Cards are installed. The System runs under Windows/XP SP2.

Now, from time to time, I cannot reload ( and thats then permanent) previously stored .pro files.

In the Scope bar I can see that some devices are loaded, but suddenly either an sfp error message occurs (in ccwindows.dll, see attachment) or the scope bar is again in the previous state.

I guess its a communication problem of the Scope card with the PCI BUS. Any idea about that ?

Thanks a lot

Peter

have you checked for shared irqs?
did you do a complete fresh installation?

Hello gary,

i think you´re right, but the problem comes with the P5Q Pro motherboard. In ACPI multiprocessor mode it is simply not possible to avoid irq sharing on this board: PCI slot 1 shares an irq with the PCIe graphic card, raid controller and usb controller. PCI slot 2 shares an irq with the PCIe Root Port 1 and 5 (even not documented).
Runnig the system in non-ACPI single processor mode seems also not an option, as I need a lot of computing power using third party software like Kontakt, Gigastudio, Kore, etc. connected to Scope/SP via GSIF,ASIO drivers.

Maybe you have an idea what to do. If I have to change the motherboard , what is your recommendation for a Scope/SP compatible board using a Core 2 Quad (Q9400@2.66 GHz) CPU ?

Thanks a lot
Peter

PS: I do not understand the (nonavoidable, as in ASUS Boards) shared irq concept, as it can cause problems with any PCI(e)-Card.

i've had very good luck with the intel p35 and 33 based motherboards. others have found the newer asus boards to be poorly laid out as well. they were made with gaming graphics in mind, not dsp audio cards. it's possible that disabling the usb port that is sharing(in the device manager) will help, although sharing with graphics is generally bad. sharing an irq with the pci-e root is often ok.

i'd try an intel dp35dp or dg33fbc if the troubles remain, both are cheap and proven, although, as with all current mobos with lots of onboard devices, you'll likely have to disable at least a few usb controllers in the device manager.
