Using AMD K6 or Cyrix/IBM/SGS-Thomson 6x86 Processor
When running AMD K6 or Cyrix/IBM/SGS-Thomson 6x86
processor and you hear a tune/music, the reason is most likely due
to #3 in the “Heatsink/Fan Related Tune/Music” section - the
heatsink/fan may not be sufficient for today's fast and hot running
processors (such as those from AMD and Cyrix/IBM/SGS-
Thomson).
AMD has verified a list of the heatsinks/fans that are most suitable
for their K6
™
processors. Please refer to AMD's web site: http://
www.amd.com/products/cpg/k5/thermals/k86thermals.html for
details.
Intel's Pentium MMX (and also most classic Pentium processors)
do not run that hot since they are manufactured under the 0.35
micron process - these require less power and they generate less
heat. Also, Intel's VRT (Voltage Reduction Technology) further
reduces the power consumption (to 2.8V) - so overall, these Intel
processors can use a relatively smaller heatsink/fan combo than the
other processor brands/types.
This sound can be intermittent or continuous. If there is one or
two quick beeps/notes, typically at boot-up, it is safe to ignore it. If
it is not during boot-up or if there's a continuous tune/music, then
there is something that is definitely not correct and it must
immediately be checked or serviced.
