I see from this page that the power measurements were done with Processor Turbo Mode disabled in BIOS. Have we ever tried disabling turbo mode while running SPECpower over Solaris on Nehalem-based system?
I haven't found any info about Dell Active Power Controller via googling or visiting the Dell website. How did you know this is a BIOS based facility? Do you have any pointers to more info? Is Dell Power Controller the equivalent of HP Power Regulator -- where BIOS is doing continuous adjustment of pstates based on utilization? This would presumably interfere with the OS trying to do the same thing... -- jdh Li, Aubrey wrote: > FYI, > Dell P-states in BIOS...
