New build problems

[Trader]

Hi all,
I just built my new CrossHair Formula iv.
The memory is: Crucial 4x4GB DDR3 - 1333 10600 UDIM NON-ECC.

The system boots to bios no problem with jus one stick in any one of the four slots.

Boots with two sticks in first and third slots and possibly other slots.

System boot with sticks sticks in 1, 3 & 4 but wont boot when sticks are in 1, 2, 3 combination and when all 4 sticks are installed.

Is this a memory problem? dont the motherboard support such memory? is it bios upgrade needd?

I'm just test booting at the moment with no operating software installed yet. Waiting for win 7 to arrive.

thanks for your opinions and advice.
