Well, he was running a chip that was obviously a 400FSB in it. Yes, the model might indicate an 800FSB capability, but then he would likely have run an 800FSB chip in there instead of the 400 one unless the 1.8 was a leftover from something else. (Or if a newer chip in there originally got fried- but then why would he ask as he probably knew what was in there in the first place.) That's why I was unsure of the capabilities of the board. Heck, he could have meant to type P4P400SE for all we know.
