[QUOTE="s-band, post: 1163319, member: 407744"] I've got 3 cards, a 6903, 6903X and 6983 on an SFF i7-8700 (4 PCI slots) PC running Win 10 Enterprise LTSC 2019. I use 6 instances of Crazyscan, one for each tuner. All seemed OK but sometimes one tuner on a random card would fail to start and often the 6903X would fail to start either of its tuners, take many minutes to start or be very slow in operation. All drivers were updated to the latest. Re-installing the cards would fix it until next boot. An irritating side effect of re-installing was that the tuner numbers would shuffle. It doesn't seem to be a Crazyscan issue as a failed tuner isn't usable with TBS utilities either. The only thing I could see was that one IRQ was shared between 2 TBS cards and the audio card (on-board): [ATTACH type="full" alt="irq.PNG"]156795[/ATTACH] I moved the 6903 to a spare slot and that gave this result: [ATTACH type="full" alt="irq2.PNG"]156796[/ATTACH] Now the 6903 and the 6983 behave correctly. However, the 6903X often will not start if another card has been run first after boot. The 6903X usually works if it is started first. The option to change IRQ is greyed out on device manager and I can't see any options that help in the BIOS. I've searched and there seems to be no sure fire way of setting IRQs now. Many answer that it shouldn't be necessary. Any ideas, please? [/QUOTE]
