AMD Athlon 64 2800+ ("Newcastle") Socket 754

AMD Athlon 64 2800+ ("Newcastle") Socket 754

[Michael Pophal]

Hi,
I decided to change my new Sempron 2600+ to a Athlon64 2800+. Does
anybody habe experiences with this CPU an CPUfreq? Does it work
together? 
This CPU knows of course 'Cool'n Quiet', but is NOT a mobile processor!
Is there a difference between powernow! and Cool'n Quiet?
I have to send the sempron back soon, so any hints are appreciated.

Thanks!

Mike

Hello all,

In the same thread I'd like to ask if is it possible to slow down a
"Intel(R) Xeon(TM) CPU 3.40GHz" with the appropriate module
()p2_clockmod)? It does not has 'Cool'n Quiet'. It is a workstation.
BTW which is the best utility to switch cpu frequencies, besides the
kernel modules of course?

Thanks,

Daniel

All Athlon64 do support C'n'Q.

I have 3000+ and my brother have 2800+. Both work with cpufreq without
any problems.
(I've even undervolted my C'n'Q :) )
Ofcorse, you should read your motherboard manual and search Internet a
little bit because some Socket 754 mobos does not support C'n'Q well if
they work with two memory modules.

C'n'Q = PowerNow! for AMD64

You're referring to p4_clockmod, and its possible to use it to slow down said 
processor, AFAIK.
However, it does not scale _voltage_ (and only throttles but does not scale
frequency) like 'Cool'n Quiet' or 'Demand-Based-Switching'. Some recent
Intel Xeon processors are capable of dynamic frequency and voltage scaling,
so you should try out "acpi-cpufreq" and "speedstep-centrino" first.
