Default Gigabyte P35 board fails EMI tests

THESE DAYS, Electro Magnetic Interference (EMI) compliance is required for nearly all electronic stuff sold in the EU, US and most of Asia. This encompasses various US, FCC and CE tests, among others. So, the user's assumption would be that all such products do pass the tests.

A fairly recent example is Gigabyte's GA-P35-DS3 mainboard, based on the Intel's P35 chipset, one of which may have been lying in waste, dropped on the floor of Taiwan's spanking new 300 km/h Shinkansen high speed train somewhere between Taipei and Kaohsiung...

Basically, according to the ETC tests, the mainboard slightly exceeds the allowed limit in the horizontal polarity (see screenshot) and vertical polarity CE EMI tests. The 5 dB difference isn't small, but isn't particularly alarming either. According to other tests, similar MSI and Asus boards were within the limits, but close to them.
