2.1 GHZ. but usually reduced by EIST to 1.5 GHz
(It can have just two values above)
I did the tests again:
CPU frequency locked to 2128.000 Mhz:
maxim@MAIN:~/tmp$ sudo ./port800
cycles: out 1650, in 1065
maxim@MAIN:~/tmp$ sudo ./port800
cycles: out 1648, in 1066
maxim@MAIN:~/tmp$ sudo ./port800
cycles: out 1649, in 1065
maxim@MAIN:~/tmp$ sudo ./port800
cycles: out 1648, in 1065
maxim@MAIN:~/tmp$
CPU frequency locked to: 1596.000 Mhz
maxim@MAIN:~/tmp$ sudo ./port800
cycles: out 1730, in 1138
maxim@MAIN:~/tmp$ sudo ./port800
cycles: out 1730, in 1138
maxim@MAIN:~/tmp$ sudo ./port800
cycles: out 1735, in 1140
maxim@MAIN:~/tmp$ sudo ./port800
cycles: out 1734, in 1139
maxim@MAIN:~/tmp$ sudo ./port800
cycles: out 1734, in 1138
maxim@MAIN:~/tmp$ 2128.000
A bit strange, isn't it?
