gaps or seams.

Processor Heatsink Grounding 

Although grounding of the processor heatsink has not yet been required on any AMD Athlon™ 64 
processor-based systems, grounding of the processor heatsink can further lower the harmonic EMI 
levels of the processor. Many AMD Athlon 64 processor-based motherboards contain grounding 
pads around the footprint area of the processor. These grounding pads can be utilized to ground 
the heatsink to the motherboard ground.  

If excessive system level EMI radiated emissions exist after attempting all the listed EMI 
reduction techniques, then more extensive remedies may be necessary. First, determine if the 
emissions emanate from the system I/O cables (including the AC power cord) or from aperture 
leaks in the system chassis. If EMI emissions emanate from a particular I/O cable, then improved 
filtering or cable shielding may be required on that cable. If EMI emissions emanate from slots or 
seams in the chassis enclosure, use copper tape across the apertures to improve shielding 
effectiveness. If copper tape reduces emission levels to a satisfactory level, then chassis sheet 
metal changes or conductive EMI gasketing can be added at that location.
