I own a cherised Scope Professional card.
I've been installing my new computer (see my signature for specs) but I think I have more dropouts now than with my older PC (ASUS P4P800 Deluxe and 2.4 GHz CPU with and AGP card)
I thought it would be great idea to spend my vacation building the new monster. I have now been awake nearly 7 days AND 7 nights to get the perfect DAW but I have dropouts, crackling and pops here and there.
I run 2 20" wide sceens in 1680x1050 resolution, tried both dual screens and one "big" one including both sceens at 3360x1050.
I have done all the tweakings in XP as I one can do
Disabled everything in BIOS as I possibly can
Put SFP in LOW and Cubase in HIGH in Activity Manager
No antivirusprograms etc
Lowered graphicsslider to the lowest settings etc
Running x1 on the BIOS settiings for the PCIe.
Tweaked with Double Dawg to get right latency for Scope (96 is standard and I tried 64 and 32 as well)
I have tested with SX3 and Cubase 4 and when I run the demosongs in Cubase 4 it sometimes works flawlessy down to 3 ms, let's say 4 ms. But if I run an old Cubase projects involving Direct X plugs and lots of VST instruments it's another case. When I click on things with the mouse, fiddling with SFP synths or something there is HEAVY crackling. My older PC seem now to have been working better.
I DONT WANT TO RUN 25 ms LATENCY IN ULLI! =)
All in machine is internal PCI express as well as my Soft RAID Sil 3132 card. Just Scope is PCI. I have tried slots 2 and 3 ( slot 1 is covered by coolers from Leadtek GeForce 8600 GT card)
I've tested to run ny songs from both RAID partition and from the second SATA2 drive which is installed in SATA port 2 on the motherboard.
I have disabled things so Scope is alone on IRQ 18 APIC mode.
I run XP Pro 32 bits with SP2 and all fixes from Microsoft.
I can't really believe that I don't get a decent musicmachine with this parts.
Im used to computers and Scope since many many years back, even professionaly (selling PCs and Cubase and worked with DAWs since the beginning of time).
All I can get it down to is GUI problems. But PCI express cards have their own "busses" and don't hog the PCI bus, ey?
Can it be my Scope card (bought it Dec 2001, manufactured Sept 2001) has gotten sick? I mean.... then it shouldn't work at all or not being able to run 3 ms in Cuase 4 demosongs?!?!?
I have also tried all in Cubase setups and with the SFP-drivers, changing latencys and ULLIs and disabled Multi CPUs etc etc etc
Can Garyb or someone else in this forum, running same motherboard etc, come up with a solution for me?
I have read nearly all the threads here and on Steinberg forums as well.
I'm now out of ideas.
Is P35 chipset wrong choice?
Can't disable all USB cause there is no PS/2 port for mouse and I must run backups to an external USB harddrive (especially if I choose to edit audio on RAID 0 in the machine)
I record vocaltakings and external synths as audio, I use many synths in SFP and the big 2448 mixer and many plugins synths and effects in Cubase.
I run Scope 4.0 and will upgrade to 4.5 soon but Ralph at CW told me there is no new drivers or applications in 4.5 (just want the new devices)
I really hope you want to and can help me in this matter. Having a new record coming out this autumn!
Feel fre to add me on MSN ( see profile)
Greetings from Sweden (on a destroyed holiday

Remarks:
I've totally disabled swapfile on C:
I run the /3GB switch in XP and it seems to be OK
I run an Evolution MK-249C on Pcs USB buss (not through SFP MIDI cable)
