I recently buiilt myself a new computer from the ground up: mobo: Asus P5E3 Deluxe Processor: Intel Core 2 Quad Q6600 RAM: Corsair TWINX 2GB DDR3 XMS 1333mhz Graphics Card: GeForce 8800GTX I inserted the RAM in the correct slots (according to the MBO User Guide) for Dual Channel config. However when I boot-up the BIOS splash screen says: Single Channel non Ecc mode. I can find nothing in the manual requiring any changes in the BIOS settings. I have queried Asus about this but have received no response. As for the official Asus forum, well has anyone tried to register with these people? The required fields demand everything but the color of your underwear. No doubt I'm missing simple and would be grateful if somebody would point me in the right direction.
