postcode Dell C6100

Hello,

I just start my new motherboard of Dell C6100 with one L5520 and 6*2Go but i have a problem:

when i start the system, i have nothing on the screen and a code post on the led looks like a 63. I search but i haven't find anything about this code.

I have access to the megarac and i see nothin crazy or whatever. With the console redirection i haven't anything too.

have you an idea?

Thanks
