i assume you have 2 RAM sticks?
1) Try them one by one and see if they are recognized.
2) Also try using different slots, i one stick is not recognized - faulty ram slot?
3) Check mobo manual and see that you are seating the sticks in the slot pairs that are defined for dual channel. Some mobos allow seating on any slots, some others allow only slot 0 and slot 2 for example, to make a dual channel pair. Try playing with this and seat them in various slots.
4) are you on latest bios? maybe an issue like this was corrected on latest bios versions.
