:o WOW ! I disabled all the C2E, thermal, and so on... options in the bios and IT WORKS ! WOOHOO !
Not any click at all anymore :D This is amazing !!! Now I have minimal ULLI latency (2ms in, 2ms out) and everything runs fine !

I could have tried the PCIE USB card as a last chance solution too, but ...

The motherboard is a gigabyte GA-EP45-extreme : there is a first PCI slot, then the primary PCI Express
then two others PCI slots, then two secondary PCI Express.

If using a PCIE USB card (and disabling onboard USB) solves the issue, I'm getting one right away.

I only have 3 PCI slots on the motherboard, and for now I can only use the two of them that are close enough for me to plug the STDM cable
between the Scope boards.

Maybe I could try the other PCI slot on the other side of the graphic board, but I would need a longer STDM cable, and anyways one of ...

IRQ 18 Contrôleur hôte étendu Intel(R) gamme ICH10 USB - 3A3C
IRQ 18 Sonic Core DSP-Board
IRQ 18 Contrôleur hôte universel Intel(R) gamme ICH10 ...

With not so recent hardware (gigabyte ga-ep45-extreme, quad core Q6600) I managed to get 2ms latency, that is 2+2 = 4 or 5ms TOTAL
latency (from input to sequencer-and-effects to output) with only one 3DSP luna board. So I guess that your latency problem is again due to this
IRQ problems. If you are ...

Hello,

You people are going to laugh (or not) . I have just bought another 3DSP luna board on eb*y : woohoo doubling my precious DSP powa !!!
I know that's very little as compared with many scope boards out there, but still enough for me since I'm a hobbyist.

BUT... I'm running all this onto a ...
