Problems with 2000Mhz memory (with an overclocked CPU)

I am very new to overclocking and not sure if I have played with the correct numbers in BIOS :)

The issue is that when I try to run my memory at 2000Mhz I end up with BSD.
Could it be that my motherboard does not support 2000Mhz? or Did I just do it wrong?
I managed to get 1840Mhz, which is not bad at all, but just wondering why I can't have 2k.

Also If someone could give me some indication if my CPU settings are ok?
Looks like that processor is running smoothly at the current clock, but I would like to aim higher if possible.

Asus M4A89TD PRO
AMD Phenom II X6 1090T Black Edit (at 4,15Ghz ~50celsius)
Noctua NH-D14
2x2GB Adata Gaming Series DDR3 2000Mhz 9-9-9-24 1,55 - 1,75v
2x4GB CORSAIR high performance XMS3 2000Mhz 9-10-9-27 1.65v
(NVIDIA GeForce GTX660 OC 2048 MB)

This is what I changed in BIOS:
CPU ratio - 18
AMD Turbo - Disabled
CPU Bus - 230
DRAM - 1840Mhz
CPU Voltage offset + 0.1875 >> 1.6995
DRAM Voltate - 1.65

Everything else in bios is on AUTO and you can see more from the pictures.

But they are 2000Mhz from the factory. I'm just wonderig why I can't get that.. Not really clocking the memory here. But yes the CL is a bit off but I was told that they are combatible and would just run on the lower CL.
 


Individually they are tested to DDR3-2000, but they are not tested to DDR3-2000 as a set, and they are not tested with a Phenom II X6 1090T infront of them, or with an Asus M4A89TD PRO bringing them together. It's very important to make sure that DRAM modules are matched as closely as possible.

High speed memory is nice to have but it's incredibly temperamental and thus it's very important to follow proper procedures when purchasing and installing the modules, as well as to be aware of the risks and challenges involved with overclocking memory controllers. The memory controller on the 1090T is only rated to DDR3-1333, anything above this is not guaranteed.
