My setup's problem(s) I traced to one of the KVR400X64C3AK2/1G pairs.
Originally, I had two KVR400X64C3AK2/1G installed in DIMM slots 1, 2, 4,
& 5. I experienced errors during installation from CD. Ntoskrnl.exe
problems on boot, and multiple forms of BSOD.

I finally decided to remove 3 of the 4 memory modules, run a single 512M
stick in DIMM slot 1, and I saw the same issues. I did the same again
with a single memory module from the other pair. No problems. I also
increased the DIMM voltage +0.1V.

I've applied for an RMA from Kingston, will see if problems continue
when I get replacement memory modules. Because, I would like to know if
this a timing issue with this motherboard when using this memory
configuration (two matched pairs of KVR400X64C3AK2/1G).
