I posted before and was told p965 boards would only work with 1.8v ram. It says so on the newegg mobo specs for Asus & Gigabyte boards. This trick was posted in the newegg consumer reviews for DS3:
Pros: i dont own this board but this im trying to help many of yall. this applies to the DS3 board too. the reason most yall cant boot up or u think ur ram isnt compatible is becuz most high end ram needs 2.0 V to get it going and the board defaults to 1.8V. u need to either buy ram that isnt rated 2.0V or buy a cheap stick of value ram ,boot with it and set 2.0 as ur ram voltage ,save it turn it off. switch out ram and presto it should work. hope this helps many of yall.
