[Phenom II CPU]
1. CPU Host Frequency will need to be 233 for DDR3-1866. CPU can natively support DDR3-1333 max, but does have an 8X memory multiplier for DDR3-1600, so that is the one you will be using. 233 * 8.00 = ~DDR3-1864
Note, this will also overclock your CPU Frequency, so you should lower the CPU Ratio if this is not desired. If you would like to keep it, make sure to find the sufficient voltage it needs to be completely stable.
2. CPU-NB Frequency should be 2800MHz, or 12X (233 * 12.00 = ~2800MHz).
Then set DRAM Timings tCL - tRCD - tRP - tRAS - Command Rate/Timing (that the memory is rated for).
3. DRAM Voltage (that the memory is rated for)
Even if the memory is 1.50V, default, it should still be manually set.
4. Lastly, CPU-NB Voltage +0.1V. This will help the CPU fully support DDR3-1866 since AMD technically supports 2 modules of DDR3-1333/1600 only.
5. F10, save, exit, and everything should be ready to go.

[Non-Black Edition Phenom II CPU]
If you have a non-Black Edition CPU, you can attempt DDR3-1600 using Method #1 in this guide:
http://www.gskill.us/forum/showthread.php?t=7688
or
manually inputting DRAM Frequency DDR3-1333, DRAM Timings tCL 8 - tRCD 8 - tRP 8 - tRAS 24, DRAM Voltage 1.50V
These are fail proof settings that should work with any DDR3-1600 CL9 or better memory kit. It is commonly used to determine whether the problem is with the RAM or the BIOS settings.

[FX or A Series CPU]
Method 1.
A. Enable DOCP/EOCP in BIOS.
a. If unstable, raise CPU-NB Voltage in addition to the above.
B. Set CPU-NB Voltage +0.05V to +0.1V depending on stability
C. F10, save, exit, and everything should be ready to go.
Method 2.
A. Set DRAM Frequency to DDR3-1866
B. Set DRAM Timings to tCL - tRCD - tRP - tRAS - Command Rate
(that the memory is rated for)
C. Set DRAM Voltage to what the memory is rated for.
(Manually set even if default 1.50V)
D. Set CPU-NB Voltage +0.05V to +0.1V depending on stability
E. F10, save, exit, and everything should be ready to go.
