If the GPU + Motherboard passes EMI compliance, then the GPU - Motherboard must also pass, since the motherboard doesn't provide shielding but only adds noise.

If the GPU + Motherboard passes EMI compliance, then the GPU - Motherboard must also pass, since the motherboard doesn't provide shielding but only adds noise. So I don't think the particular motherboard should matter. The measured interference will always be >= to the real interference produced by the GPU under test.
- exikyut 8y agoHmm, good point, didn't quite look at it that way. But now I'm wondering if there are motherboards out there that radiate a little bit more than they should, and force peripheral vendors to do extra work clipping EMI in their own products. This is probably not true, since all PCI card vendors would have to test their products with tons of different boards.
