Re: Spread spectrum

depending on the BIOS (most only support spread spectrum on AGP or PCI Express, not memory or PCI - so far i have only seen one motherboard that allows spread spectrum on the latter) it can spread the generated EMI across a wider frequency spectrum, which can reduce the "damage" on audio circuits. Note it doesn't actually reduce EMI, just spreads it "thinner".

If you can, try "underclocking" - that will actually reduce EMI, but be careful, you may create a non-bootable PC (in which case you need to reset the CMOS).

You could also try EMI shielding, for example, wrapping the audio card and ribbon cables using aluminum foil (grounded). Be careful about creating short circuits or unintentionally trapping heat.
