Thought I'd post a bit of information that through lots of experimentation I and others have found out about this board.

One of the key issues with the Canterwood was the ability to have PAT enabled as long as you had a C-based PIV and a minimum of DDR400 RAM. According to Intel it was supposed to always be enabled if the criteria was met and the FSB didn't exceed 200. Yeah, I realize there's some falacy here.

I received version 2 of the board (latest release) with BIOS P05. I immediately updated to BIOS P07, then P08, and finally P09. In the process of testing and benchmarking this board I learned by using CPUz and CTIAW that PAT was listed as disabled. Playing around with BIOS releases I flashed back to P05 and found that PAT showed enabled in both the above mentioned utilities. Not only was PAT enabled but all my benchies jumped up 250-400 points.

This issue was directly addressed with Intel support by several friends that found the same results as I did for my board. Intel stated that PAT was always enabled and that that it could not be disabled as long as the appropriate criteria were met. They also stated that they were working with SiSoft and other benchmark designers to fix their misreporting.

I believe as do many other that have this board that BIOS P05 is the only current BIOS release that has efeectively enable PAT on this Intel board. I wonder why?

Me too, me too! I have two of these boards, one rev 1 and one rev 2 and they both behave the same way with the PAT-on/Pat-off, P05 thingy.

If anyone's interested, there's a giant, pulsating ever-growing thread about this mobo over at ABX.
