It is pretty simple. Go into Advanced Chipset features, and
take things off their "Auto" type settings. Try something like
"System Performance" [User Defined], to expose as much of the
customization features as possible. You will find, the fact that
the BIOS screen exposes new settings when you change things like
this, makes gaining access to the customization features pretty
simple. (You should be able to figure it all out, in about
30 minutes of playing around.)
I take it you've got some good memory, as the Nforce2 is pretty
picky about RAM. The RAM issue only shows up when you try to
reach FSB400/DDR400. If you find you cannot get past 180-185MHz,
then suspect the RAM first. If you get "CPU failed due to
overclock" messages at POST, and yet the computer still boots into
an OS, then you should be running tests on the memory (memtest86
as well as Prime95), as when everything is working properly
(i.e. machine is Prime95 stable), that message will disappear.
I'm currently using CAS2 memory on mine.
The most time consuming part of overclocking, is proving the
CPU/memory are stable. Fiddling with the settings is only a
tiny part of the effort.
Normally, I'd recommend visiting http://www.cpudatabase.com/CPUdb/
to see what overclock is possible from a given model of
processor, but there aren't any Sempron processors in the list
yet. If you do succeed in overclocking, there is an email link
on that web page, and perhaps you can submit your results to
them, so they'll include a Sempron section.
And those forums are useful, even if you have to read a lot of
posts to learn something. Nforcershq does have a lot of useful
info, especially if you are having problems with peripherals
on the board etc.
