Big Bang Xpower RAM issue

[maninashed]

So I have the board and I've been trying to fix this issue. It's been happening since I installed everything yesterday. The BIOS shows that 4gb is available but you can see the other two 4gb sticks (In CPUID it shows 12gb and 4gb in slots 1,3,5. It is 4gbx3 Mushkin Enhanced Blackline 12GB DDR3 1600 (PC3 12800). I've tried out all the sticks in slot 1, the RAM itself is fine. What should I do? Reinstall Windows with 1 stick and put the other two in after the Win7 installation, or what? I'm stuck...

Thank you ahead of time

Btw quick edit, I have updated the BIOS to the most current one found on the forum.

Two reasons can be uneven pressure of an aftermarket CPU cooler, or there may be bent pins in the CPU socket or poor pin to CPU pad contact.

Check for bent pins and reseat cpu

Are the RAMs already inserted to the black color slots?
