3200+ -> X2 4000+

Hi guys,

I bought a new X2 4000 processor and I have 2 questions:

-- can I use the same cooler (my processor uses the
deprecated Socket 939) ?

-- should I change a lot of attributes in my kernel .config
file?

TIA

Maybe, depends on how good your cooler is.

You need to enable SMP and the multi-core scheduler option

If its the cooler that came with the 3200+ then no, don't
use it for a
dual-core chip. even though most of the times temps will be
fine, when
loading both cores heavily it would really strain.

no. Btw, the if you buy 'the real thing' the dual cores come
with a nice 
self-regulating cooler. And this boxed cpus are not much
more expensive than 
a single cpu.

enable smp. The rest should be fine. You can but don't have
to enable 
multicore support. Don't enable numa. Have acpi enabled.

Shouldn't he set the timer frequency to 250 or 300 as well?

BTW: I'm still not sure if he talks about the boxed cooler
or something he 
bought separately.  The latter should do fine...

whats with the NUMA stuff?

Not if it's going to be a desktop.  Hires timers are not
common in
x86_64 in the kernel yet (no tickless support) so for now
1000 is still
best for desktops.

in my experience 300 is 'best' for my desktop.

nothing. If you only have once cpu with two cores, don't use
it!
