Need help choosing right Memory for MoBo/CPU

All components brand new:
CPU: AMD FX-8350
MoBo: Gigabyte FX 990 UD3
Thermaltake 750 W
GeForce GTX 650 2GB DDR5

Current Memory:
16 GB Crucial DDR3-1600 (4 X 4GB)

If you look here, I described my initial RAM problem here:
http://www.tomshardware.com/answers/id-1771268/stuck-gi...

Essentially either my CPU or MoBo (or the combo) won't take 4 sticks. I had to put one in slot 2 and another in slot 4. Adding a third or forth causes boot issues. I don't really know if it the sticks/slots are damaged, but I see nothing.

Can anyone recommend a solution or new RAM that will be compatible with my components? This is a brand new build. Right now I only have 8GB, but I would like at least 16GB in there.


Thank you in advance.

Does the system boot with single RAM stick in any of the slots?
Have you tested?
For memory, what brand (Corsair, Kingston, GSkill)?

Yes it does boot with a single RAM stick in any of the slots. I have tested it.

The memory is from Crucial.

I have two of those 8GB kits.

Doesn't really matter. I have a question. I just went into BIOS and there is a "System Memory Multiplier" auto enabled for 8.00

Can I set it to 1600MHz?

It would not help, in my opinion.

Prob need to increase DRAM voltage + 0.05 and raise the CPU/NB voltage to about 1.2 to give the MC (memory controller) a boost
