Hí Subhuman,
thank you for your response.
Unfortunately I have to use USB because my Mouse is attached (ok PS2 would do it) but I have also Steinbergs USB2Midi and a Emagic EMI 2-6 attached. So my main worries are that if I push my Pulsar1+2 to its limits (which I havent done yet, as I didnt use them in a project up to now since I got em) that the heavy load of the USB will sooner or later stress the PCI Bandwith.
Ok here is my setup to give you a detailed scheme:
AGP Slot = Geforce 2MX DH
PCI 1=Adaptec 2940AU
PCI 2=3COM 905B NIC
PCI 3=free
PCI 4=Pulsar 1
PCI 5=Pulsar XTC
PCI 1 (and I think 2) share AGP
PCI 3 shares the disabled onboard Audio
PCI 4 and 5 shares USB
So the only slots which share both each other are 4/5. I thought already about plugging them to 3 and 4 but I think it will end up in a mess if they are not shared each other.
Concerning the forcing:
Yes I did force IRQ 5 to PCI 4/5 but what happens is that the USB IRQ sticks somehow also with it. If I force 4/5 to be IRQ 5 then the USB is also 5 although there are left many IRQs in the system like 3,9 and 15.
PCI Latency is set to 128 with no problems. This BIOS Read ahead feature is also enabled.
Arbitration scheme is untouched yet (but will try it)
All in all a very tricky thing going on here.
"May the nForce be with me"

If you're not using USB disable it in the BIOS.
Check your mobo manual, ASUS generally comes with a chart that shows which PCI slots share with which resources. Put the Creamware cards in slots that share only with each other, not with anything else.
You might have to force an IRQ for these "shared slots" in the BIOS (you can do this on CUSL2, for example)
Remember "TweakBIOS" and "PowerTweak" to adjust the PCI Latency Timer to 64 or 128, and the PCI Arbitration Scheme should maybe be set to PCI instead of CPU (try it, at your own risk of course
Do a seach on the tweak/power programs on google to find them, PCI latency is probably in your bios already since you have asus, arbitration will only be in those programs.
