Overclocking a Conroe and Using Speedstep/cpufreq.

Overclocking a Conroe and Using Speedstep/cpufreq.

[byteFrame]

Word up.

When I dont overclock my cpu (2.4 ghz) cpufreq works
fine (with the ondemand governor) but when I overclock
the cpu to 3.0 ghz in the bios, cpu freq doesnt work.
They neccessary sys files arent in
/sys/devices/system/cpu0/ etc etc. I had orginally
been using the acpi cpu freq driver, but the "Enhanced
Speedstep" inst working either (gonna try it without
an option, but I doubt itll work)


Does anybody know anything about this? Ive been told
it works in windows.


slackware 11 with kernel 2.6.21-ck2/conroe e6600(2.4
default)/ evga 680i motherboard

Thanks homies.

Your BIOS only knows about speeds the chip is rated for.
