I noticed that too. here's /proc/cpuinfo (for one of the cores) on my
PhenomII X2 550 (black edition), not overclocked:
processor : 1
vendor_id : AuthenticAMD
cpu family : 16
model : 4
model name : AMD Phenom(tm) II X2 550 Processor
stepping : 2
cpu MHz : 3100.000
cache size : 512 KB
physical id : 0
siblings : 2
core id : 1
cpu cores : 2
apicid : 1
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 5
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov
pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb
rdtscp lm 3dnowext 3dnow constant_tsc nonstop_tsc pni cx16 popcnt lahf_lm
cmp_legacy svm extapic cr8legacy abm sse4a misalignsse 3dnowprefetch osvw ibs
ts ttp tm stc 100mhzsteps hwpstate [8]
bogomips : 6228.99
and it shows the correct cpu MHZ. However, I note that the bogomips shown
by yours is slightly higher than mine, which would correspond to the 3200 Mhz
clock speed. So, I don't understand why yours shows 800 while mine shows
the true rated clock speed. If yours was really underclocked by a factor
of 4 (which would be the case if it were actually running at 800 Mhz) the
bogomips wouldn't be what you're getting.
I wonder if it's an artifact of how the BIOS reports info to the kernel?...
