I'm using 2 Pulsar II boards succesfully for years now in SFP Mode. and had XTC mode running in the 3xx and 4xx era.

Now I was hoping to get XTC Running now it is supported in 5 but I get crashes and these error messages:

ScopeDriverloctl (1908900 returned error code -99

PepDisplayObject::GetHardwareInfo: invalid board-no 0


I'm using a ASUS P5Q-e and Cubase 5 as sequencer. and a NVIDIA 9500XT with latest drivers.

I tried With ACPI and without in a clean install but no succes....
I'm trying to fix this for days now but have no idea what's wrong..

Anyone some ideas?

The "scopedriver" error i something that happens when you use your daw with multiple cores. You have to set cubase to only use one core. I hope wc Will fix this soon

I use XTC with Sonar and Reaper on my quad core, with all the cores on, and I never saw this error...

Its only a problem ón some motherboards. I have had 2 now with the same problem. Other users have reported this problem as well. But its great that its working for you!

This happens at times with me on my P4 with Hyper Threading enabled.

How dó you disable ht?

You have to do that in the BIOS, at start-up.

I'll try that. Thanks
