Just because the processor is rated at 1200 doesn't mean that the motherboard is running it at that speed. Any time I've seen this problem, it was because the motherboard was left to autodetect the CPU speed and didn't do so correctly (don't know why they seem to incorrectly guess 1G) Check your BIOS settings. > > ===Cut=== > FreeBSD 4.8-PRERELEASE #0: Sat Mar 1 12:01:00 YEKT 2003 > emz@freedom.norma.perm.ru.:/usr/obj/usr/src/sys/FREEDOM > Timecounter "i8254" frequency 1193182 Hz > CPU: Intel(R) Celeron(TM) CPU 1000MHz (1009.95-MHz 686-class CPU) > Origin = "GenuineIntel" Id = 0x6b1 Stepping = 1 > Features=0x383f9ff > ===Cut=== > > I have the same problem on 4.6-RELEASE (real CPU frequency is 1700 > MHz): > > ===Cut=== > FreeBSD 4.6-RELEASE #0: Mon Oct 7 17:54:30 YEKST 2002 > emz@tiger.norma.perm.ru:/usr/obj/usr/src/sys/TIGER > Timecounter "i8254" frequency 1193182 Hz > CPU: Pentium III/Pentium III Xeon/Celeron (1009.95-MHz 686-class CPU) > Origin = "GenuineIntel" Id = 0x6b1 Stepping = 1 > Features=0x383f9ff ===Cut=== > > I have some FreeBSD-boxes running with CPU frequency lower than 1GHz - > FreeBSD detects them correctly. > > Is it some kind of misconfiguration ?
