After just reading your post tekjunkie i realized that with BIOS version 0511 I get no difference in memory bandwidth with P1 + P2 enabled? With RAM running at 1605Mhz (7-7-7-21 1T) I get the same bandwidth with P1 + P2 at "Auto" and with it "Enabled"? They mention something about how P1 + P2 work in Anandtech's Striker II Extreme review but I forget what they say (something about it only comes in handy at a FSB higher than 475Mhz or maybe it was only FSB speeds below 475Mhz)? In anycase I see no difference whether its enabled or not. So far I have not experienced any of the issues you mention with BIOS version 0511 (but I've only been using it for a couple days so far)?
