	A 190 MHz base clock and 1.47500V core was needed to run the system stable without the "Current Limit Override" (CPU TM) kicking in. The current limiter will decrease the CPU ratio multiplier when the processor exceeds 130W or 100A, mainly a feature that is desired in servers, workstations, and laptops. SuperPI finished a 1M run in 10.984 sec.		A 190 MHz base clock and 1.47500V core was needed to run the system stable without the "Current Limit Override" (CPU TM) kicking in.
