If you have an AMD Phenom II CPU motherboard combo, and DDR3-1600 memory, the system BIOS should be configured as follows:

[Non-Black Edition CPU]
Method #1
1. Set DRAM Frequency to DDR3-1333.
2. Set CPU Host/Bus Frequency to 240 (this will overclock the memory frequency to DDR3-1600)
2a. Raising the bus frequency will also overclock the CPU, so if you do not want this, you will need to lower CPU Ratio to your desired frequency. If you do want to keep it, you may need to raise CPU VCore to stabilize the overclock. If you have a Black Edition CPU, then it should be capable of the overclock without any voltage adjustments, but for non-BE's most likely you will need to raise CPU VCore.
3. Set timings to tCL 9 - tRCD 9 - tRP 9 - tRAS 24, or whatever your memory is rated for.
4. Set DRAM Voltage to 1.50V, or whatever your memory is rated for.
5. Most CPUs will need a CPU-NB Voltage boost of +0.10V, so if your default is 1.10V, set it to 1.20V.__________________________________________________ __________________________________________________ __
[Black Edition CPU]
Method #2
1. Set DRAM Frequency to DDR3-1600
2. Set CPU-NB Frequency to 2400MHz (DDR3-1600 / 2 = 800MHz, then x 3) CPU-NB Frequency should always be 3X DRAM bus frequency
3. Set HT Link Frequency to 2400MHz
4. Set timings to tCL 9 - tRCD 9 - tRP 9 - tRAS 24, or whatever your memory is rated for.
5. Set DRAM Voltage to 1.50V, or whatever your memory is rated for.
6. Most CPUs will need a CPU-NB Voltage boost of +0.10V, so if your default is 1.10V, set it to 1.20V.__________________________________________________ __________________________________________________ ___
There are many different motherboards and memory, but they require the same changes. If you are unsure of what to change, refer to your motherboard user's manual. It will have more information about each option and its purpose.
If the system is slightly unstable, you may need to raise CPU-NB Voltage. This is the memory controller voltage, so raising this voltage can help with stability. Also, if you are using full slots or attempting any overclocking, raising this voltage can also help with stability.
Once these changes are made in BIOS, your system should be stable. For memory above the standard, majority of the time AUTO default settings will not work, so these settings are required for a perfectly stable system. Recently we have noticed that without manually setting DRAM Voltage, it can cause stability issues.
If you continue to have problems, you can also attempt DDR3-1333 CL8 (8-8-8-24) 1.50V. These are good settings if you can not get DDR3-1600 to work. These are fail-proof settings to test the memory and make sure they are working properly. If the memory does not work with these settings, it is possible that your memory kit is bad.
As always, we can assist if you have any difficulties, so feel free to create a post.
Thank you

it's just toooo stable and tooooooo energy efficient and toooooo quiet haha
