Hi,
Once every few years I dig into things to build me a new PC for daily
work.
What I need now is the power to work on hi-res audio (94KHz/32bit) and
8 megapixel RAW images. But most of the time I'm not a power user,
doing writing, webmastering, etc.
So what I'd like is a silent, energy efficient PC, which I can put in
high gear, only when I need that. And it would be very nice to 'switch
gears' on the fly, without rebooting and changing BIOS settings.
I'm a novice in 'clocking', but reading a lot I'd like to use a
Mobile Athlon XP 2500+ barton (or 2400+/2600+) and 2x 512Mb DDR400.
As I understand it would be best to have a motherboard where you can
set memory, bus and CPU speeds independently and can change (lower!)
Vcore voltage.
I'd like to reach sub 1GHz speeds, would be nice to get CPU power use
under 10 watts. And maybe overclock when I'm in a hurry doing pictures
So what motherboard (Socket A) to buy?
Main thing is being able to change the settings above and especially
being able to set low (1,1 volt or so) Vcore voltages, on the fly
(that's why I go for the Mobile Athlon).
And I'd like a chipset with passive cooling, no fan!
Options is not a priority, don't need 5.1 sound (use my pro card), no
RAID, only Firewire and Gigabit LAN would be welcome. But I don't mind
to buy a more expensive board (with many options), as long as I can do
the right CPU settings.
BTW, I already have a Asus A7N8X Deluxe, but I (now) understand that
is not the one to have for underclocking, after reading this article
http://www.tomshardware.com/cpu/20041001/ where at
http://www6.tomshardware.com/cpu/20041001/athlon-underclocking-08.html#multiplier_in_the_bios_boot_with_what
it says "Unfortunately, it is only possible to change the multiplier
on a few motherboards. One of the fastest, the Asus A7N8X-E, crashed
every time we tried." I guess that's thru for the A7N8X Deluxe and
most NVIDIA nForce2 boards too.
Don't mind using a other chipset but maybe a MSI K7N2 Delta2-LSR could
be a nForce2 option, as I understand the MSI software 'CoreCell' and
'CoreCenter' can change BIOS settings on the fly? But I can't get
enough info (MSI not replying when asked about the range of Vcore
voltages).
Thanks for any advice,
Boyd Noorda
