I not see anything related to that. Looking again, there is a BIOS entry named "Ratio CMOS Setting" whose help reads "Sets the ratio between CPU Core Clock and the FSB. Note: For CedarMill and Prescott Family CPUs, the setup option only available when Intel SpeedStep technology is disabled.". However, I'm not sure whether or not the E5420 is either a CedarMill and Prescott Family CPUs, or maybe the BIOS is just not enabling the feature. I did not try to boot a Linux on that platform. - Arnaud > Thanks > > On Thu, Sep 15, 2011 at 6:20 PM, Arnaud Lacombe <lacombar@gmail.com> wrot= e: >> Hi, >> >> >From today's -CURRENT: >> >> Copyright (c) 1992-2011 The FreeBSD Project. >> Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 >> =A0 =A0 =A0 =A0The Regents of the University of California.
