My first guess would be memory but you've changed that; no guarantee that the new stuff is OK. Try pulling the memory from the board that works great. Try just using one stick, then two, then four. Compare the dmesg and /var/log/syslog from each box. Try a serial console and the first thing you do on boot is cat /var/log/syslog. This way you can capture it before the box crashes. Swap drives between the systems. Last (since you have to disturb the heat-sink grease), swap the CPUs from one to the other MB.
