EMI reduction (not for the faint of heart)

[silent tone]

I was reading on the AVS forum today, where they were trying to get rid of noise in the ground plane and EMI inside a PC case. Aside from routing all the power & data cables and stuff, I heard something new. Apparently the component leads that stick out the back of the mobo make decent antennaes and radiate directly toward the mobo tray, causing a good deal of noise. A solution is to clip off all the stubs, leaving only the rounded solder joint. Has anyone tried this? Can you get higher FSB or RAM overclocks?

For those who don't know: EMI is the Electrical Magnetic Interferance field that is emitted around each and every wire in a cable. Each wire can not only 'send' a signal, but it can 'receive' a signal. No realistic gain in prevention of this phenomea on the pin protrusions on the board, but by adding metalic over-braided round cables into the equation, you confine the range of the signal and capture it within a conductive cage. Now by peeling back the connector back cover, you can gain acces to the braided shield and add a drain wire to a ground plane. DO NOT TERMINATE TO MOTHERBOARD ! Run drain wire ground, attach to chassis where hard drives attach - any screw.
End of EMI signal, end of EMI problem.

im not really sure this is a real problem.

On the contrary. I think my CPU won't overclock because NASA has a microwave antenna pointed at my house. Because it's not anything I did. Time to start snipping!
