If it is locking up as soon as you start putting load on it, perhaps you
have a crappy power supply or bad ram. I know many people on this list
have had strange lockups and in the end it always seemed to come down to
using bad ram (where bad ram is defined as any ram that isn't perfectly
within it's claimed specifications since the memory controller on AMD
cpus _will_ try to use it to the limits of the claimed spec). Power
supplies that are under powered or just badly designed may also have
trouble dealing with sudden changes in demand on power (which certainly
would happen when the cpu decides to change frequency and voltage level
due to change in demand when powernow is enabled). What kind of power
supply are you using?
