Is it possible to disable the use of spread spectrum clocking for the PCI Express channels on the DX58SO2 motherboard? We've received a card from one of our partners that was developed for an embedded system with asynchronous clocking on PCI Express and they've asked us to see if we can use it with some of our desktop systems. I've not found any mention of this being supported in my review of the system documentation but I wanted to make one last effort to make sure I didn't miss anything. Thanks!
