chipset dependant?

chipset dependant?

[A van Staalduijnen]

At home I am running an old box, running an Athlon XP on the old VIA KT133 
(not KT133A) chipset. Since this box is mostly idle I am considering doing 
the old Athlon bridge hack, to turn the cpu into an Athlon XP-M, thinking 
I could be using cpufreq then, in order dynamically scale frequencies.

I wonder though if it would suffice to turn the cpu into a 'mobile', or if 
it would require a different chipset on the motherboard as well (as for 
Intels)?

Any chance cpufreq will work after modding the CPU, or would it be 
useless?


Thanks,

Arjan

useless.  You have no variable VRM on your motherboard, likely no BIOS tables,
and at best you'll just get a new CPU string in /proc/cpuinfo. At worst,
you'll get a dead cpu.

The mod to turn the XP into an MP won't give you M)obile capabilities
but M)ultiprocessor caps. AFAIK the KT133 chipset doesn't implement any
power saving mechanism at all. Bummer...

Chipset dependant?

At home I am running an old desktop box, running an Athlon XP on the old 
VIA KT133 (not KT133A) chipset. Since this box is mostly idle I am 
considering doing the old Athlon bridge hack, to turn the cpu into an 
Athlon XP-M, thinking I could be using cpufreq then, in order 
dynamically scale it's frequency.

I wonder though if it would suffice to turn the cpu into a 'mobile', or 
if it would require to have a different chipset on the motherboard as well.

Any chance cpufreq will work after modding the CPU on this motherboard, 
or would it be useless?
