Don't rule out hardware problems until you've tried a different model motherboard. Some old ASUS boards have a problem where, under intense memory load, the voltage drops below the signalling threshhold and the box locks up as you've described. (ASUS won't readily admit to this or any of the other bugs in their boards, but ask them why they did the third revision to the P2B-F.) That's just an example, but the point is that both of your P4T-Es could have the same bug.
