Well, what is the question ? I have a very similar setup, and
that is what I use. I have some 2-2-2-6 memory in mine.

One thing you might check, is if the DIMMs are inserted in
dual channel config. For dual channel, one stick goes in
the "lonely slot". The second stick goes in either of
the other two slots. Using the picture in the manual,
dual channel is DIMM1+DIMM3 or DIMM2+DIMM3 for your two
512MB sticks.

Note that the Nforce2 is picky about RAM. When running
in dual channel mode, at DDR400 rates, that is the most
taxing config for the Northbridge. You should try running
Prime95 (www.mersenne.org) and its "torture test" option.
It is a Windows or Linux program that does a calculation
with a known answer, and can detect subtle problems with
the processor or with the memory. It is a good test to see
if your combo of memory and Northbridge is working OK.
If it stops with an error within minutes, you've got trouble,
otherwise it should run for hours.

If the memory doesn't seem to be running clean, you have
a "DDR reference voltage" setting. Get the datasheet for
your RAM and see what the limit is for Vdimm. 2.7V should
be safe with any memory, and I think that is what I'm using
right now. Use only as much voltage as is needed to
stabilize the memory, and stay below whatever voltage
the product info states is the max. Using excess voltage
only makes the memory run hot, and in extreme cases, has
been known to destroy memory overnight.
