I'm using an Athlon 2800+ Barton w/333 MHz FSB. It is matched to the PC2700
RAM.

When using a GA-7N400 Pro motherboard with two new 512mb Crucial PC2700
memory modules in a dual-channel configuration, Windows XP crashes or
reboots the system. However, the system runs well with the same memory
modules in a single-channel configuration.

What CPU are you using? And more to the point......is your memory
frequency synchronized with the FSB frequency?
